[ROOT] H932 - lafploit 1.5 up to v20a

WARNING​
DO NOT LET YOUR PHONE REBOOT, OR POWER OFF UNTIL I TELL YOU THAT IS WHAT YOU NEED TO DO.
If you do, I am not sure what shape your phone will be in.
This should go without saying, but you MUST have your bootloader unlocked (check OEM UNLOCK in developer options AND fastboot oem unlock). If you don't, you will probably brick your phone.
If you use this on any model V30 besides the H932, you will be stuck in a bootloop, and you will not be able to fix it since you will have wiped out download mode!
This is safe if no mistakes are made (typos, missing a step, etc). However, if you do mess up, the risk is high that you lose download mode at best, or brick your phone at worst.
If you deviate from this procedure, and think: "I can just skip a step, or I can do this on my own Linux install". Don't complain if you brick your phone.
PREREQUISITES:
You MUST to be on 10d: link
You must have H933 10h laf installed. You will need the KDZ: link
We are going to flash this using the patched LG UP: link MOD EDIT: original link dead. Try THIS ONE instead
It MUST be installed in: Crogram Files (x86)LG ElectronicsLGUP
You can't just unzip it anywhere and run it, it will not find the model file.
You need TWRP: link
You need an SD card that is formatted for FAT16 with TWRP copied onto it EXACTLY as it is named when you download it.
You need to grab FWUL (version 2.7 or later) and burn it to a USB stick: link
Even if you have Linux, and you think you can install the dependencies, don't. I know this works from FWUL.
After installing TWRP, grab @weakNPCdotCom's latest TWRP flashable ROM threads: Oreo 20s or Pie 30d
MOD EDIT: If your phone is (or has been) on Pie, you need to use a later LGUP version to roll back to Nougat 10d, then SWITCH to the original LGUP version linked below for the remaining steps. See this post for details.
PROCEDURE PART 1: Getting a working LAF onto your phone
By far this is the most dangerous part of this procedure.
Make sure you are on or downgraded to 10d
Boot to download mode
In LG UP, choose partition DL.
Pick the H933 10h KDZ
Click start
You will be given a list of partitions to flash, ONLY check laf
Click start
You will get a warning about additional modified partitions -- ignore it, and click OK.
As a safety feature, LG UP will start flashing those modified partitions after laf completes flashing.
After the flash is initiated, pay close attention to the "step" and as soon as it changes from laf to another partition, PULL THE USB CABLE!
If you let it completely flash the H933 KDZ, your phone WILL reboot, and you WILL have a brick that can't be fixed.
You NEED to pay attention. The additional partitions that are flashed are very small. The second that step changes from laf to
the next partition, PULL THE USB CABLE!
Click OK and it will start flashing.
Once laf is flashed, and you have pulled the USB cable, you can click exit, and then re-open LG UP.
Choose partition DL again, and this time pick the H932 10d KDZ.
Select all partitions except laf. If you forget to uncheck laf, you will have to do this all over again.
When it completes, it will reboot your phone.
Go back into download mode. This time you will be running the H933 laf, and we can continue with PART 2
PROCEDURE PART 2: Installing TWRP
Boot from your FWUL USB stick.
Put your phone into download mode. With the phone powered off, hold vol up and plug in the USB cable. You do not need to
touch the power button -- the phone will power on and enter download mode.
Once booted, login. The password is: linux
Double click the LG folder that is on the desktop
Double click on LG LAF (runningnak3d) icon and you will be at a terminal prompt.
The following are the commands that you enter into that terminal. You can copy / paste them if you like.
MOD EDIT: Refer to THIS POST to make sure that LGLAF is able to read the SD card
Code:
git pull
git checkout h932-dd-write
./step1.sh
When you are told to, pull the USB cable, and the phone will power off. You now have TWRP installed. At this point you can flash a ROM, or Magisk or whatever you like.
You must use the key combination (with phone off, hold vol down + power. When the LG logo appears, immediately release and then hold power until you get the the factory reset screen. Choose yes twice and you will be in TWRP) to IMMEDIATELY boot into recovery. If you don't, then recovery-from-boot.p will wipe out TWRP, and you will have to do THIS part again.

PROCEDURE PART 1: Getting a working LAF onto your phone
Make sure you are on version 10d. Again, check in Software Info / Software Version if you are unsure.
Boot to download mode
In LG UP, choose partition DL.
Pick the H933 10h KDZ
Click start
You will be given a list of partitions to flash, ONLY check laf
Click start
You will get a warning about additional modified partitions (cache, OP, userdata) -- ignore it, and click OK.
Click OK and it will start flashing.
Once the flash completes, your phone will reboot into the OS. Just power off, and go back into download mode.
Choose partition DL again, and this time pick the H932 10d KDZ.
Select all partitions except laf. If you forget to uncheck laf, you will have to do this all over again.
When it completes, it will reboot your phone.
Go back into download mode. This time you will be running the H933 laf, and we can continue with PART 2

PROCEDURE PART 2: Installing TWRP and rooting
Make sure the SD card is in your phone.
Boot from your FWUL USB stick.
Put your phone into download mode. With the phone powered off, hold vol up and plug in the USB cable. You do not need to
touch the power button -- the phone will power on and enter download mode.
Once booted, login. The password is: linux
Double click the LG folder that is on the desktop
Double click on LG LAF (runningnak3d) icon and you will be at a terminal prompt.
The following are the commands that you enter into that terminal. You can copy / paste them if you like.
Code:
git pull
git checkout h932-dd-write
./lglaf.py
These next commands you will type into the LGLAF shell. It will look like this:
Code:
LGLAF.py by Peter Wu (https://lekensteyn.nl/lglaf)
Type a shell command to execute or "exit" to leave.
#
You will type these commands at the # prompt that you see above. When you enter the commands, you will NOT get any indication that the command completed. However, if you get this:
Code:
Hello, I am LAF. Nice to meet you.
then you typed the command incorrectly, and you need to try again. There are TWO spaces between !EXEC and toybox.
Also, the phone will NOT indicate that flashing is taking place since we are using dd and NOT the normal WRTE opcode. When you enter !CTRL POFF, the phone will go to 100%.
Lastly CAPS matter. These lines need to be typed exactly (better to use copy / paste). If you mess up, it is no big deal, just try again.
Code:
!EXEC toybox dd if=/storage/external_SD/twrp.img of=/dev/block/sde bs=4096 seek=10246\0
!CTRL POFF
You can now pull the USB cable, and your phone will power off. You now have TWRP installed. At this point you can flash a ROM, or Magisk or whatever you like.
You must use the key combination to immediately boot to TWRP:
Power off your phone
Hold vol down + power.
When the LG logo appears, immediately release power (and ONLY power) and then immediately hold power again until you get the the factory reset screen.
You never let go of vol down until the factory reset screen appears. Once it appears, you can release both buttons.
Choose yes twice by using the vol down key and power to select, and you will be in TWRP.
You should only tap the power key to select yes. Don't press and hold, and don't spam the power key.
It takes TWRP a little bit to boot -- be patient.
If you don't do this, and you let the phone boot into the OS, then recovery-from-boot.p will wipe out TWRP, and you will have to do THIS part again.
By THIS part, I mean if you mess up the key combo, and the phone boots to the OS, you only have to do PART 2 -- not this entire process.
ROOTING:
OK, so now you are in TWRP, we need to flash a few things or TWRP will be wiped out, and your phone will be encrypted again.
First swipe to allow modifications
Choose wipe / format data / type yes
Choose reboot / recovery -- this will reload TWRP. Do not choose reboot / system. Make sure that when it reboots you are able to mount data without it prompting for a pin / passcode.
If it does, then you need to format data again and reboot to recovery because you chose WIPE and not FORMAT.
Pick install, and browse to your SD card where you have Magisk, dm-noverity-opt-encrypt, and rctd remover
You can install each one individually, or you can add them all together in the queue -- it is your choice. Also, Magisk needs to be flashed first -- the order of the other two zips doesn't matter.
Now that they are flashed, reboot to recovery yet again just for good measure. If everything looks good, reboot to system and you should have a rooted phone.
OPTIONAL:
If you would like a second copy of TWRP on your laf partition (I *highly* recommend this), follow these instructions:
Download the version of TWRP that you want to install onto laf.
Rename it to twrp.img
Boot your phone to TWRP, and connect it to your PC
Open a command prompt where you downloaded TWRP and type:
adb push twrp.img /sdcard/
adb shell dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/laf
With the phone off, hold vol up and plug in the USB cable and you should be greeted by your second copy of TWRP.
CLEANING UP:
If you do NOT want TWRP on laf, then we at least need to get the H932 laf back onto your phone.
Download this zip onto your phone: h932_laf.zip
Boot to TWRP
Choose install, and browse to where you downloaded the zip
When it finishes flashing, you will have the H932 laf back.
I can't say this enough, you should really consider keeping two copies of TWRP around. You will never be in a situation where you go: "Man, I wish I had download mode, but all I have is TWRP".
However, there are plenty of times that you may wish that you had a second copy of TWRP. Imagine flashing a ROM that wipes out recovery. Oppps. Imagine flashing a new version of TWRP and
it doesn't boot -- again -- opps.
-- Brian

I've added link to WTF instructions pointing T-mobile H932 users to here. ALL other V30/30+/V30S can use that easier method, but T-mobile H932 HAS to use this method.

OK -- those are the final instructions for now. Root away!
I have upgraded to Oreo, and then downgraded to 10d and tested this 4 times so I know it works fine. However, getting H933 laf onto your phone is dangerous. PLEASE pay attention and pull the USB cable. You can be too quick -- pulling it while it is still flashing laf. If you do, then you just need to flash 10d and start again. However, if you wait and your phone reboots, the H933 has a different RSA key and your phone is toast.
I don't have a TMO G7 to test with, but this should work for them as well. Just need to find the correct laf to flash for them.
-- Brian

I remember when the OP released this method for the T-Mobile G6 (I used to have one). Many bricked their phones in the process. Others were successful and happy. Too risky for me.

I can't post a screenshot right now, but here ya go -- proof that this works:
Code:
joan:/ $ su
joan:/ #
joan:/ # cd sys
sys/ system/
joan:/ # cd system/
joan:/system # cat build.prop | grep H932
ro.product.model=LG-H932

First thing: Nice job, Brian! Thank you, and those who helped bring this to light by being guinea pigs.
Second: Brian, there appears to be a break in the link for FWUL. I was still able to copy the link text, then take the break out after pasting it into the address bar to get to the page, but wanted to let you know that the break is there.

Man I hope that's true but the g7 has a locked bootloader HTC style unlock now. LG haven't unlocked the Tmo version last I checked unless I missed something
Also, so it's okay to OTA to Oreo now? I'm on nougat and much rather be on Oreo

NOOO Don't ever take an OTA. You will need to flash an Oreo zip to get back. I am guessing there isn't one since there would be no need.
I don't have time to make one today unfortunately.
EDIT: and what?! you mean TMO finally has a locked bootloader on the G7 just like all other carriers? They didn't just strip fastboot flash, they removed oem unlock as well?

I should have added im sick in bed today and haven't rooted yet so itd be a 100pct stock OTA. Is it still not recommend to OTA to Oreo beforehand?
And yup, it appears LG has done the HTC style unlock and the Tmo version isn't unlockable yet and probably won't be Imo. I think it was LG but could be Tmo since it seems the more custs they get, the more like at&t they become

If you did, you will be wasting your time since you have to downgrade to 10d.
I will try to get a 20a flashable zip up as soon as I can.

Wow. Being so sick has made me not think straight . I can't believe I didn't think about that since you have to flash back to 10d.
No pressure on the flashable. It isn't that big of deal for me or us but thanks for thinking about us with the extra work.

Hey Brian. I dont know if you saw my pm but im glad it works

@me2151 No, sorry, my PM box is so backed up. I am going to have to spend some time this weekend going through it.
This isn't quite the same as lafsploit for the H918, but the concept came from research for that project.
Next tasks:
* Get Oreo and root working on the V20
* Get all other G6s root in addition to the H872
* Consider buying a V30 so I can help here as well

Ah lol. My pm had jsut suggested taking a look into the h932 since its similar to the h918 in regards to bootloader. yea you should join us. I have my P rom working now. ill probably hold off on releasing it to the public though til i do more features. However. Only non stock rom to have enforcing on Joan

@runningnak3d
You stated, "You need to grab FWUL (version 2.7 or later) and burn it to a USB stick: link
Even if you have Linux, and you think you can install the dependencies, don't. I know this works from FWUL."
When I went to the page it has 2 options/2 types of FWUL... which should we download:
"Main Download Server:
persistent mode ( read FAQ #4 ): Latest version (click)
forgetful mode ( read FAQ #4 ): Latest version (click)"
I'm guessing Persistent mode version....?
Thanks

Feedback
I had a moment to go through the instructions as a "typical user", and am providing feedback to make this as painless as possible, crystal-clear, & hopefully prevent any bricks!: (Please correct any inaccuracies!!)

EVERYTHING should be said!!! Especially things that will brick our phones People like me that ARE extremely computer literate and have been 'custom rom-ing' for almost a decade still won't know all of these nuances. I've been just catching up on all of these advancements with the V30 and your latest discovery, read hundreds of posts, but I still won't pretend to know everything! And apparently a mistake like this could've made my phone gar-bosh. So don't underestimate peeps like me So: in Android phone settings->Developer Options: There are 2 checkbox(es) we need to select? "OEM Unlock" and "Fastboot OEM unlock"? (Im not sure about the latter mostly)

Fat32: I've used SwissKnife https://swissknife.en.uptodown.com/windows to do easy FAT (same as FAT16) formatting. I say this because I already saw issues around this.
I'm looking to buy a V30 only since you figured this out Much thanks! I'll say that again, you're awesome & I'm jealous! It sounds like now ALL variants can get the bootloader unlocked and a custom recovery installed: H932 via this thread/method & all other variants via WTF exploit (Again, please keep me honest!). (I just want to double-check my info so I (& others) buy a phone that will be able to get a custom ROM & plan to get the H932 and will report back if/when I get band 71 working for those interested.
I know some of you that have been in this since the beginning are thinking, come on man, read the posts! Like I said, I have been for over a week. There are thousands of posts, and even if I/we read EVERYTHING, we still wouldn't be able to decipher the bad info from the good! ...so thanks for your patience I'll post more once I actually try this. And thanks again Brian!! Really awesome...

Umm... For all of us that use this and get it working, I think we should do donations until Brian can get a free V30, eh?!? (Can't yall read between the lines ) Besides, think of all the additional support you'll get if he actually has a phone to test with!! haha

@igotroot
Did you get it working yet? If not I can run you through the hardest part of it. Also, choose the persistent FWUL. Basically persistent mode means it saves your data when you leave. It's just easier that way

v30 Recovery Un-Brick Zips

LG V30 Recovery UnBrick Zips​
So as some of you are aware, I released a h932 rom that soft bricked a few devices. well in the process of that I (with @runningnak3d help) figured out a way to unbrick those devices. As long as you have TWRP or download mode with ADB then you can unbrick. These zips here are NOT meant to be flashed to just flash. These zips are for those people that have a non 9008 brick only! DO NOT FLASH THESE ZIPS OR RUN THESE COMMANDS FOR ANY REASON EXCEPT FOR A NON 9008 BRICK! DO NOT FLASH OR RUN THIS COMMANDS BECAUSE YOU HAVE A BOOTLOOP! ONLY FOLLOW THIS THREAD FOR NON 9008 BRICKS! PLEASE BE SMART!
Now on to the good stuff.......
Only download and flash the zip made for your original device model. Do NOT flash whatever your converted too. for example i have a ls998 converted to us998. I would flash the ls998 THEN convert to us998 later on...
NOTE: After flashing the unbrick zip for your model youll need to have a rom zip on your sdcard or internal storage. You'll need to flash that rom zip (aosp or stock) in order to boot
Recovery Zips
H932_Dump.zip [Download]
See Post 2 [Post 2] for what to do if you do NOT have TWRP
See Post 3 [Post 3] if you want to contribute to this thread and backup your device models EMMC for others to be able to recover. ( NO PERSONAL DATA WILL BE USED )
Don´t forget to hit the thanks-button if you like this zip! :good:
You want to help me with a [donation?] Not asking for it, I have fun doing this for you, but feel free...

#RESERVED1
For those of you that dont have TWRP but have download mode and ADB, you have a second option of just manually running the commands to unbrick.
Step 1 - Make sure you have ADB installed on your computer
Step 2 - Download the zip for your orginal device model
Step 3 - Extract the zip and place all the files into a folder called dump
Step 4 - ADB push the folder to your device ( adb push <file path to dump> /sdcard/ )
Step 5 - Open the update-binary file inside the extracted zip inside META-INF/com/google/android
Step 6 - Run all the make_ext4fs commands in adb shell (adb shell make_ext4fs <partition name>
Step 7 - Run all the write_raw_image commands in adb shell ( NOTE : remove $INSTALLER in your commands and replace write_raw_image with dd ) ( EXAMPLE : adb shell dd if=/sdcard/<partition name> of=/dev/block/bootdevice/by-name/<partition name> )
Step 8 - Once this is done you'll need to reboot and profit.
If any questions about this guide please feel free to tag me and ask and i will help you
thank you

#RESERVED2
Make sure you have enough space on internal storage before flashing the backup zip. You'll likely need 10GB+. this new zip now checks free storage on internal and aborts if not enough. it also now creates a flashable restore zip so now youll have the restore zip internal storage/dump/backup.zip and you can flash this zip when you get a non 9008 brick
Dumps can be done with aosp or custom roms but please try to backup only stock roms if possible. Thanks Everyone!
EDIT: NEW ZIP HAS BEEN ATTACHED.

#RESERVED3

#RESERVED4

I'll be releasing the flashable zip to dump your partitions later today!

Added a flashable backup zip. please flash in twrp and then upload Backup.zip from internal storage Dump folder somewhere and send link here. ill make a restore zip so we can make the v30 almost unbrickable :good:

LG V30 bricked
Hi!
I need your help please, if there is any help... (I hope this is the right thread for my topic)
I got my LG V30 a few days ago (on 8.April 2019, EU version, H930). I schwitched it on and made the initial setup (wifi, region, ...). And the "normal" system update. (I think, it was sec.update from 1.1.2019).
After 2 days I wanted to root the phone. My mistake ....
The steps in short:
1. adb and fastboot installed (on my laptop with Windows 10). I copied SR5-SuperSU-v2.82-SR5-20171001224502.zip into the root of the phone (no sd card in the phone).
2. with adb and fastboot (and LG develpoer account + imiei & co) I managed to unlock with my unlock.bin
3. phone restarted. Since then I see an additional start screen "Lock the bootloader." for 1-2 sec at every start/restart. After this the boot process continues with the standard screen : LG V30 ThinQ powered by Andriod
4. restarting the phone with volume up + power buttons did not funtcion (I gave 4-5 times a try). It never ever succeed for me on this phone. Maybe this is an important point...
5. restarting into the new feature of the phone worked out only with adb reboot bootloader
6. I flashed TWRP in Win10's cmd with fastboot flash recovery recovery.img (I renamed TWRP-3.2.3-7-DataIMG.img to recovery.img)
7. restarting the phone with volume up + power buttons still did not funtcion (I gave it a try 4-5 times)
8. I found this hint : fastboot boot recovery.img. It did the job, TWRP was started (Version 3.2.3-7 DataIMG).
9. I made a backup in TWRP, copied the BACKUP directrory to my laptop. (maybe the only smart thing of me...)
10. TWRP started with fastboot boot recovery.img again
11. in TWRP -> intsall -> SR5-SuperSU-v2.82-SR5-20171001224502.zip selected and the 'restart' option checked.
12. I have seen, that SuRoot....zip was succesful installed (without any errors) and the phone rebooted automatically (it was connected via USB cable to the laptop, but it should not be the problem)
13. since then nothing happens, but the boot screen: for short time the screen with bootlocker text, then only the black screen with LG v30 ThinQ powered by Andriod
I can not boot in to TWRP with volume up + power buttons. This never worked for me. I tried it 20-30 times... :crying:
With volume up + power buttons I can restart, but only the screen with bootlocker text, then only the black screen with LG v30 ThinQ powered by Andriod appiers.
My laptop does not recognise the phone on USB.
Before I destroy the phone with a hammer, any hints?

Your mistake was not following any of the rooting Instructions in this V30 forum. If you did, you know we don't use SuperSu, we use Magisk. That's probably what messed up your phone.
I understand you obtained an "official" bootloader unlock code from LG for your H930 -- which is not necessary now for almost a year with the WTF exploit -- but you still need to follow the rooting instructions guide.
The unlocked bootloader warning screen is normal. Ignore it, it's just a harmless annoyance. You would have learned that if you read the instructions.
Try manually going into Download mode (power off completely, then hold volume up button while plugging in USB cable) -- if you can, then reflashing most recent full stock H930 KDZ via Dev Patched LGUP in "Refurbish" mode. Dev Patched LGUP is attached to post #1 of that thread.
If/when you recover, your bootloader should still be unlocked, but you'll have install TWRP again and this time use Magisk. Read the WTF instructions, but you can skip the bootloader part, as you've already done that. You can start with Section 6. Read those instructions on a web browser, not an app.

Thank you for your quick reply!
I'm learning this forum threads, intstuctions and flashing... And I am now preparing for the unbricking.
After installing LGUP, what dev zip files do I need?
LGUP+V30DLL_PATCHED.zip
LGUP_common_DLL_V30_ALLVARIANTS.zip
LGUP_common_OREO.zip
I can take this kdz: H93021w_00_OPEN_EU_OP_0121.kdz, right?

Are you able to get into Download mode?
You want the "patched" version, but be sure to read the installation instructions.
Yes, you can use that KDZ.
If for some reason your bootloader is not still unlocked, you can run your code again.

Sent via open market LG US998 V30/V30+

So just uploaded a new zip in post 3. this new zip now checks for free space and will abort if theres not enough to create the backup and flashable restore zip. need at least 10GB in Internal Storage. the zip will now create automatically a flashable restore zip :good: i designed this around the v30 but in theory it should be able to work on all qualcomm devices and maybe even some other SoCs as well. but this has not been tested on other devices. ive fully tested this on my ls998 and everything works great! Enjoy!

john, did i ever tell you, that i like your work and efforts? good man! :good:

Lg v30 h932 brick
Hello, I need your help.
My LG V30 H932 phone is left as a BRICK after installing an erroneous kdz, it does not enter download mode or emergency mode, is there any way to revive it?

For those of you that dont have TWRP but have download mode and ADB, you have a second option of just manually running the commands to unbrick.
Step 1 - Make sure you have ADB installed on your computer
Step 2 - Download the zip for your orginal device model
Step 3 - Extract the zip and place all the files into a folder called dump
Step 4 - ADB push the folder to your device ( adb push <file path to dump> /sdcard/ )
Step 5 - Open the update-binary file inside the extracted zip inside META-INF/com/google/android
Step 6 - Run all the make_ext4fs commands in adb shell (adb shell make_ext4fs <partition name>
Step 7 - Run all the write_raw_image commands in adb shell ( NOTE : remove $INSTALLER in your commands and replace write_raw_image with dd ) ( EXAMPLE : adb shell dd if=/sdcard/<partition name> of=/dev/block/bootdevice/by-name/<partition name> )
Step 8 - Once this is done you'll need to reboot and profit.
If any questions about this guide please feel free to tag me and ask and i will help you

LG V30 Recovery UnBrick Zips​
So as some of you are aware, I released a h932 rom that soft bricked a few devices. well in the process of that I (with @runningnak3d help) figured out a way to unbrick those devices. As long as you have TWRP or download mode with ADB then you can unbrick. These zips here are NOT meant to be flashed to just flash. These zips are for those people that have a non 9008 brick only! DO NOT FLASH THESE ZIPS OR RUN THESE COMMANDS FOR ANY REASON EXCEPT FOR A NON 9008 BRICK! DO NOT FLASH OR RUN THIS COMMANDS BECAUSE YOU HAVE A BOOTLOOP! ONLY FOLLOW THIS THREAD FOR NON 9008 BRICKS! PLEASE BE SMART!
Now on to the good stuff.......
Only download and flash the zip made for your original device model. Do NOT flash whatever your converted too. for example i have a ls998 converted to us998. I would flash the ls998 THEN convert to us998 later on...
NOTE: After flashing the unbrick zip for your model youll need to have a rom zip on your sdcard or internal storage. You'll need to flash that rom zip (aosp or stock) in order to boot
Recovery Zips
H932_Dump.zip [Download]
See Post 2 [Post 2] for what to do if you do NOT have TWRP
See Post 3 [Post 3] if you want to contribute to this thread and backup your device models EMMC for others to be able to recover. ( NO PERSONAL DATA WILL BE USED )
Don´t forget to hit the thanks-button if you like this zip! :good:
You want to help me with a [donation?] Not asking for it, I have fun doing this for you, but feel free...

You tried to cross flashed another variant stock KDZ over your T-Mobile H932? Not sure why you would do that, but normally that results in 9008 brick which needs remote viewer Octoplus help to recover.

The T-Mobile root guide does say flash the LAF partition of the H933. But only the LAF partition. Some people do not pay attention and flash the entire H933 kdz over the T-Mobile H932 and brick their phone.
Just had a guy in the Frankenstein thread who said he followed instructions. I didn't believe, told him so, and asked him to tell me step-by-step what he did... Turns out rather than flash US998 Nougat, then Master Reset, then Oreo of choice -- he flashed 20f (Oreo), Master Reset, 20g Oreo.
I asked him why he did that. He said US998 20f was Nougat. That's like saying a banana is an apple. "10" is Nougat, "20" is Oreo. Plus, in my instructions I have specific download links to all requisite firmware, which he ignored.
He said he downloaded KDZ from LG-Firmwares website who told him US998 20f was Nougat -- which they didn't. But even if they did, who cares? You're following MY instructions, so use my download links. Once he downloaded actual Nougat from my download link -- hey that worked!
Also use the Dev Patched LGUP which I recommend. Some guy over the telegram thread said he was following my instructions, but used Uppercut. Of course that's going to fail. None of my instruction mention Uppercut and never will because it doesn't work on Oreo or later and conflicts with Dev Patched LGUP. I always include the specific version of Dev Patched LGUP you should be using. (The Dev for Uppercut is amazing, but it just doesn't work on our phones past Nougat. If it's NOT in the Instructions, don't use it.)
This isn't a recipe where you can substitute your own ingredients.
You need to read carefully and pay attention.
I'm happy to help -- but while some people's problems are quite preventable, once occurred may not be fixable.

H931 Devices Possibly Other Variants Wifi Fix Android 10 Roms (Liquid 10, LineageOs)

Short Story: Updated to pie us99830b kdz after flashing some things and clean flashed 10 roms again and somehow wifi wanted work ok since then. I also made backups but I am not clear if they will work without first getting pie blobs through kdz. This fix is not necessary on all LG V30 variants so first check if your model works with the roms fine. May also want to double check Zachs adb shell commands do not work on your device or do that also just in case (bottom).
Suggestions: This may actually take some time if you run into problems. Might be good idea to throw your sim in another phone so you don't stress. Smoke a bowl or open a beer.
Warning: AOSP rules may apply here although everything seems well with both permissive/enforcing for me. See that thread. Proceed at your own risk. If anytime you are not detected in download mode you must flash an oreo stock twrp zip such as h93120h or us99820e.
Files: Wifi working for me with this method on each 10 rom I have tested(Liquid, Lineage, AEX, ION, Havoc) so find one of those. You may also need us99820b kdz(us99810d if 20b doesn't boot clean some reason), the h93030q twrp zip, kernel(huamea 1.9.3 suggested) and h930 22j modem (https://drive.google.com/file/d/16o93WU262HWv2fKPYnMxC81GY6bJ3Txd/view?usp=sharing).
Quick Steps:
20b kdz partion all boot to setup screen then power down+fastboot+install/boot twrp+ magisk-decrypt-ak3remover zips+boot to setup screen again(don't setup) then power down+download mode+ 30b kdz partition all. Decrypt error for me first boot with 30b kdz so "reset phone" may be needed if greeted with that screen. Get to actual setup screen on 30b then power down+fastboot+twrp(cancel on encrpyt error)+format+wipe all(but sd)+reboot recovery. Then finally your selected poison havoc q+open gapps+magisk+decrypt for a clean flash. After booting in once I then reboot to twrp and flash huamea because it temporarilly removes root which needs to be reflashed.
Troubleshooting Suggested Steps:
Prior Potentially Unecessary Steps*
i. First install the 10 rom without wifi and make a backup or use mine below of chosen rom (in my case us99830b clean flashed to liquid/lineage)
ii. Clean flash h93030q twrp zip +magisk+disable encrypt+22j modem.img boot to startup screen then reboot to recovery
iii. Format data then wipe all but sdcard/otg and restore the Q backup. Goal here is to get the wifi initially clicked in, but the calling quite likely will still not work now. You can attempt to flash some stock modems to see if they work for you but I had no such luck. Reflash 22j modem after if you do test others.
iv. If the 30b kdz has not been booting up flash us99820b kdz partition all then reinstall twrp. If the 20b kdz restarts by itself after booting up you must partition dl all us99810d kdz first before 20b.
Steps
1. Format data then wipe all but micro sd don't reboot
2. Go back and reboot recovery
3. Magisk+disable encrypt
4. Power off then download mode(volume up while plugging in cable)
5. Partition dl all us99830bkdz using patch lgup
6. Let it boot to first welcome screen but don't setup anything
7. power off then fastboot mode(volume down while plugging in cable)
8. In adb & fastboot enter fastboot flash recovery then fastboot boot twrp.img
9. Will get decrypt error still in twrp for second just hit cancel
10. Repeat steps 1 & 2
11. FLash Liquid 10.1+Opengapps or Microg if wanted+ Magisk+ disable decrypt zips and boot it to start screen but don't setup
12. -Optional-Reboot Recovery Flash Humea kernel 1.5-1.9.3 or another to stabilize wifi/ better battery life(could possibly be done in prior step, may possibly lose root) and reboot
13. Andy's Fingerprint fix for internal error promp at startup(some roms ok without): Download osmosis busybox and magisk props config hide. Reboot then type "su" in any terminal then "props", follow prompts and select lg-v30 h930. The error should go away on boot.
*The prior steps here initally fixed wifi for me but I still didn't have calling, so I chose partition dl all partitions(only way kdz seems to boot) using patched lgup back to us99830b to test again which I assumed would cancel this procedure out so alas still not 100% sure if required. A dev has said though if you get wifi on your device once you will always have it. Wifi has been sticking for me afterwards until flashing any oreo kdz then I must re follow quick steps.

Zachs Faster Wifi Fix for some lucky LG V30 users:
" - you need a kernel with dm-verity disabled (custom kernel, etc.) - for now the one of the haumea_I.base kernels allow this process
- Magisk must be installed (root permissions)
- get into a shell and become root (adb shell -> su ; or via other means)
- cp -a /vendor/etc/wifi/WCNSS_qcom_cfg.ini /mnt/vendor/persist-lg/wifi/WCNSS_qcom_cfg.ini
- in my example wlan_mac.bin is copied to /storage/emulated/0/joan_int/wlan_bins/wlan_mac.bin (that's internal storage and a newly created folder joan_int and subfolder wlan_bins)
so the final command to "fix" all is
cp -a /vendor/etc/wifi/WCNSS_qcom_cfg.ini /mnt/vendor/persist-lg/wifi/WCNSS_qcom_cfg.ini
cp /storage/emulated/0/joan_int/wlan_bins/wlan_mac.bin /mnt/vendor/persist-lg/wifi/wlan_mac.bin
chmod 644 /mnt/vendor/persist-lg/wifi/wlan_mac.bin
you copy over the WCNSS_qcom_cfg.ini file to the expected place (the symbolic link is wrong)
and copy over the missing wlan_mac.bin also to the expected place"

Shouts out to @ChazzMatt , @SGCMarkus, @kherio, Andy, Zach, Chiru, Harris, and others on telegram for the group think. Any difficulities after following these steps you can hit up @tyl xda / Andy on telegram, he was able to use a slightly differed spin using persist lg files which may work for you. I will try to update as things get figured out

Power & Vol+ before Yellow Warning : System with magisk (Short yellow warning)
Vol+ on Yellow Warning : TWRP
If you want to return to stock erecovery, do these:
Boot into twrp
Push erecovery image to /cache: adb push drag & drop img file to console /cache
Flash erecovery to erecovery: Install > Install Image > Select erecovery image from /cache folder > Pick erecovery_ramdisk partition > Swipe
Spoiler: Passing Safetynet (For Android 12 and Below
Keep in mind that Safetynet is deprecated and Google is encouraging developers to switch to Play Integrity API. To pass safetynet you need to have 3 checkmarks, as such you'll need to follow all 3 instructions I'm about to give you.
Spoiler: Evaluation Type Basic
Disable "Spoof Pixel 5" & Enable Safetynet in phh options then reboot.
Download YASNAC from play store and check for "Evaluation Type" from result.
If it says Basic and others fail you can skip this part.
If test fails or doesn't finish do these:
Install Magisk
Enable Zygisk & Enforce denylist
Install Universal SafetyNet Fix module by kdrag0n
Now check YASNAC again. It should finish test and say Basic in evaluation type.
Spoiler: Basic Integrity Fail
This happens because root is detected most of the time.
If your GSI has Dynamic Root, uncheck root from phh settings.
If your GSI has SU, securize from phh settings.
If you had to flash magisk because of evaluation type, tick google play and google play services in denylist.
If those didn't fix, contact GSI maintainer.
Spoiler: CTS Profile Match Fail
This happens because build fingerprint is not play certified.
Make sure you have safetynet option ticked in phh settings and do these:
Edit /data/adb/phh/secure
Add these 2 lines to bottom:
resetprop_phh ro.build.fingerprint HUAWEI/ANE-LX1/HWANE:9/HUAWEIANE-L01/9.1.0.368C432:user/release-keys
resetprop_phh ro.build.version.security_patch 2020-08-01
Reboot and test again.
Everytime you untick safetynet you have to edit this file again. You can also pick any other fingerprint from here should you choose to. You need both fingerprint and patch date. If you want to simulate other devices add following lines:
resetprop_phh ro.product.brand HUAWEI
resetprop_phh ro.product.device HWANE
resetprop_phh ro.product.manufacturer HUAWEI
resetprop_phh ro.product.model ANE-LX1
resetprop_phh ro.product.name ANE-LX1
Spoiler: Passing Play Integrity (For Android 13 and Beyond)
If you want to pass it you're going to have to read this wall of text. I can't shorten it.
What is Play Integrity:
Google enforces Play Inregrity once your api level is set to 33 (android 13). I currently don't have enough information about it other than apps can decide which checks to perform on your device. One of those checks is called strong integrity. We can't pass strong integrity because it requires hardware backed checks which our device lack. However you can still fool some apps that don't enforce strong integrity.
How you can fool it:
Ever since magisk retired magiskhide, some forks have been made to keep it maintained and improved. One of those forks is Magisk Delta. Before you head over to it's github and install it, you still need to install a valid CTS fingerprint. Then you can install Magisk Delta.
Steps:
Disable Spoof Pixel 5 & Enable Safetynet from phh settings if they exist.
Add these 2 lines to bottom of /data/adb/phh/secure (create if it doesnt exist) & Reboot
resetprop_phh ro.build.fingerprint HUAWEI/ANE-LX1/HWANE:9/HUAWEIANE-L01/9.1.0.368C432:user/release-keys
resetprop_phh ro.build.version.security_patch 2020-08-01
If you have magisk :
- Download Magisk Delta apk
- Change .apk to .zip
- Install it as magisk module
If you don't have magisk :
- Download & install Magisk Delta apk
- Patch recovery_ramdisk & flash it via fastboot
Enable Zygisk and MagiskHide from Magisk Delta App
Install this module : https://github.com/HuskyDG/safetynet-integrity-fix/releases
MAKE SURE GMS IS NOT IN HIDELIST
Reboot and test safetynet. (Feel free to link any app that tests for Play Integrity)
Spoiler: I went back to EMUI, why it looks like aosp?
That happens because EMUI stores it's themes and few stock apps in /data/hw_init folder. When you factory reset with stock recovery, they are preserved. But when you use twrp to factory reset they are removed. Doing factory reset once from twrp is enough to make EMUI think it's corrupted, in acuality it isn't. To fix it you can either let EMUI update from system settings or you can download this, extract hw_init folder and push folder to /data from twrp with this command :
adb push drag & drop hw_init folder to console /data
Flashing LineageOS 16.0​Note:​Stock kernel from EMUI .300> have trouble with wifi. Use Phenix 4.9.319 or above to fix it.

Firmware finder has been revived and you can use that to get your prefered cust or build.
If you need only one image not the whole build, I uploaded each one you'd typically need below.

SYSTEM.img
VBMETA.img
VENDOR.img
XLOADER.img
They are from .401 c432.
If you wiped /data once you probably won't have emui themes etc if you go back to emui. To fix that you can push hw_init folder (in data.7z) to /data. Not the contents of it, just put the folder in root of /data. It should be like this: /data/hw_init
Spoiler: Hisuite
Connect your phone to pc and open up hisuite. Check for updates and if it finds one it'll download following files update_full_base.zip, update_full_ANE-L01_hw_eu.zip and update_full_cust_ANE-L01_hw_eu.zip to your documents folder. update_full_base.zip file contains main UPDATE.APP. You can extract images from it with Huawei Update Extractor
Spoiler: EMUI's System Updater
Flash magisk patched image from quick links. After you get root in EMUI allow system updater to do its job and update. It'll ask to reboot, allow it. It will throw you back to system after reboot because recovery is not stock. Get a file manager that allows root access. Allow system updater to download again. But this time do not allow it to reboot. First one downloaded OTA, second one downloaded FullOTA. Which is better for archival purposes. After download is done go to /data/update with a root file explorer. Copy HwOUC folder to internal storage and from there to your pc. There should be 3 folders with numbers. You can find our main update_full_base.zip in one of them.
Spoiler: Downgrading
Spoiler: From EMUI 9 to EMUI 9
Spoiler: Using just the SYSTEM.IMG
Get files of your prefered build. I recommend build .278. Extract SYSTEM.IMG from UPDATE.APP via huawei update extractor and flash it with fastboot flash system . Factory reset with stock recovery then flash any TWRP except for the official ones. Official TWRPs freezes when wiping /data which is what we need to do. After wiping /data boot into system. You should have aosp background with square app icons if you did correctly. Check for system updates and it should find your current build. Download and install.
Spoiler: Using dload from Certain Russian Site
BOOTLOADER WILL RELOCK, DON'T DO THIS IF YOU DON't HAVE YOUR BL CODE
For this you need to have a sd card that is formated as exfat. Fat32 doesn't allow >4gb files so exfat is required. Download your prefered build from Androidhost.ru or mega link above. Inside the zip file you'll find a folder named dload. Extract this folder to somewhere and transfer it to your sd card. Folder structure should look like below. Hw_eu and L01/L21 will depend on your region and single/dual sim status. After this unplug your phone and shut it down. Start pressing vol- vol+ and power all at the same time. Different kind of yellow warning will appear and a screen with blue progress bar over black background will appear. If you downloaded correct variant for your phone it'll start progressing. After process is done you'll boot into stock emui with NO yellow warning. This is because your bootloader is locked. Do whatever you want at this point but remember, unlocking bootloader again will low level factory reset your phone.
-/storage/AAAA-BBBB/dload
---/update_sd
---/ANE-L01_hw_eu
---/ANE-L21_hw_eu
Spoiler: From EMUI 9 to EMUI 8
If I recall correctly there is only one way to do this. You can't dload between emui versions. You also need to be on stock emui for hisuite to function. Some people say a specific hisuite version is required but it wasn't the case for me. Plug your phone to pc, hisuite should show up beside your phone in drives section. Install it and open it. Do whatever it instructs you to function correctly. After you see your phone in app click Update button. Then click on "Earlier Versions". It'll show version 8.0.0.167 along with some warnings. Rest it pretty straightforward. Follow along and it'll return you back to emui 8. But if you're doing this to unlock your bootloader, build .167 is not enough. Exploit that dc-unlocker uses is patched in this version. So you have to roll back further. I had success with .125 build but up until .150 could work. Link to .125 build.

Getting Stock Firmware Files And Downgrading​Prerequisites:​
Unlocked Bootloader and FRP
adb and fastboot installed on pc
Huawei Update Extractor
Firmware Zip (EMUI8 and EMUI9)
HiSuite
Erecovery
EMUI's System Updater (via root)
HuRUpdater Guide / HuRUpdater Download
HwOTA
Getting stock files are problematic because of huawei. Least shadiest way to get them are the hardest so bear with me.
Androidhost.ru : Click the EMUI9 from prerequisites and search p20 lite. You should get a wide variety of versions to pick from. Make sure to match the Cust in the file to yours if you don't know what you're doing. C432 for Europe for example. After you download the zip file open it up and find the dload folder. You can either get this folder and paste it right into your sd card to force dload or you can open this folder and extract update_sd.zip. Inside update_sd.zip you'll find a file named UPDATE.APP. Use Huawei Update Extractor to open this file and there you'll see all the partitions you need. If HUE gives error while opening it, go to settings and untick "Verify file checksum". You can extract .img files by right clicking and selecting extract option on each partition. Normally you can't open these .img files but after pushing them through simg2img you'll be able to explore them too. But lets be real if you need guides for this, all you need is recovery_ramdis.img.
Using Dload Folder : Your sd card can't be FAT32 for this. FAT32 by nature don't allow files larger than 4gb so you can't get this folder to your sd card. Format it to ExFat via any guide on the internet then copy the dload folder to your sd card's root. It can't be inside any folders. Then shut your phone and press Power + Vol+ + Vol- all at the same time. It'll boot to erecovery which'll check the integrity of files then install them regardless of your EMUI version. So it is a good way to downgrade. Keep in mind tho you can't dload back to emui 8 from emui 9. And any successful dload will lock your bootloader back.
Hisuite : You can actually get firmware files pretty easily with hisuite but it requires real work. You see, hisuite downloads firmware files right into your documents folder. Connect your phone to pc and open up hisuite. Check for updates and if it finds one it'll download following files update_full_base.zip, update_full_ANE-L01_hw_eu.zip and update_full_cust_ANE-L01_hw_eu.zip. It might not get all 3 files most of the time so you have to copy each of them and update a few versions consecutively to get them. Keep in mind, it deletes each update file after it is successful so make sure to make a copy of them some place else. I recommend reverting back to EMUI8 through hisuite and then updating it to latest one to get all files. It is tidious but you need to do this once. It doesnt update you to .370 from .132. It'll send you .132 then .200 then .368 then latest whatever. You can actually use these files with HuRu updater or HwOTA to manually update. Or you can get the UPDATE.APP inside them and extract images with Huawei Update Extractor.
Erecovery : This one requires some network knowledge and it'll only get you the latest version so I don't think it worth the hassle. You need a router that allows you to change dns address for DHCP clients. Which most of them do these days. Now you need to create and run a dns server on your pc. I recommend adguard home. Pihole works too. Use Windows Subsystem For Linux or Docker to install either of them. Once you get them up and working set them to log dns requests. I believe you know where this is going. Open your router's interface and enter adguard home/pihole ip address which maps back to your pc's local address. Check if it works or not by opening up few sites on your phone which should be connected to your wifi and isn't set up to use a different dns server. If all is good open up erecovery on your phone and connect to your wifi. If you set it up correctly it should get the latest version from huawei which will show up on your log. Use that url to download it to your pc and extract it same as others. There was a paid service that used this method to send specific versions to your erecovery.
EMUI's System Updater : This is tricky and my favorite. Get the official TWRP .img and patch it with magisk manager. Then flash it via fastboot. I know, "twrp and magisk? wtf?" just do it. It takes a long time to boot but it works don't question me right now. After you get root in EMUI allow system updater to do its job and update. It'll ask to reboot, allow it. It will throw you back to system after reboot cuz recovery is hijacked. duh. Get a file manager that allows root access. Allow system updater to download again. But this time do not allow it to reboot. First one downloaded OTA, second one downloaded FullOTA. Which is better for archival purposes. After download is done search for a folder named HwOUC in /system. Copy it to internal storage and from there to your pc. You can find our main UPDATE.APP inside update_full_base.zip. Other zips include cust and all that which HuRu and HwOTA requires.
Magisk​Prerequisites:​
Unlocked Bootloader and FRP
adb and fastboot installed on pc
Stock recovery_ramdis.img
Notes:​Officially speaking magisk support for our device is dead. Magisk decided to retire magisk-in-recovery method which our phone uses. But hey it is still working without modifications unlike a-only devices so that's a win. As a foot note, you CAN use twrp image instead of stock recovery_ramdis.img but it'll take longer to boot. Using .380's recovery_ramdis.img on .278 build will not work. Make sure to match your EMUI build with ramdisk you're flashing. Ask me how I know.
Steps to install older version:​
Get the Prerequisites
No, I mean literally just get the Prerequisites and thats it
Open up your browser and find a bin service (pastebin will suffice)
Create a paste with following
Code:
{
"app": {
"version": "8.0.7",
"versionCode": "4834",
"link": "https://github.com/topjohnwu/Magisk/releases/download/manager-v8.0.7/MagiskManager-v8.0.7.apk",
"note": "https://cdn.jsdelivr.net/gh/topjohnwu/[email protected]/app/src/main/res/raw/changelog.md"
},
"stub": {
"versionCode": "18",
"link": "https://github.com/topjohnwu/Magisk/releases/download/manager-v8.0.7/stub-release.apk"
},
"uninstaller": {
"link": "https://github.com/topjohnwu/Magisk/releases/download/v21.4/Magisk-uninstaller-20210117.zip"
},
"magisk": {
"version": "v21.4",
"versionCode": "21400",
"link": "https://github.com/topjohnwu/Magisk/releases/download/v21.4/Magisk-v21.4.zip",
"note": "https://topjohnwu.github.io/Magisk/releases/21400.md",
"md5": "ee6dd05579776e7de3a6077087846e53"
}
}
Get the paste's raw url
Take the recovery_ramdis.img to internal storage
Install magisk manager 8.0.7
Open it's settings and select custom channel
Write the raw url you just created
Allow it to check for updates and it'll find that 21.4 is the latest version
Click install and select recovery_ramdis.img
After it finishes patching get the magisk_patched.img to your pc
Get your phone to fastboot mode
After connecting to pc, write this fastboot flash recovery_ramdisk to console and drag magisk_patched.img over to console and press enter
Now if you enter recovery it'll boot to android with magisk but if you boot normally it will not detect magisk so each time you restart you have to use Power + Vol+ combo in order to get magisk
Remember to switch custom channel to stable channel if you want to receive updates.
I know that you can pretty much reduce the amount of flashing and restarting by flashing twrp to erecovery but since erecovery is a lifeline for most people here I decided not to get into that. But for those who are interested check this thread.​

I wish good luck to those who will use your guide .

Among other things, the HwOTA and HuRupdater methods have not worked since February (unless someone has the necessary files stored on the disk). Huawei changed servers and Firmware Finder is dead.
EMUI 8 firmware download doesn't work for the same reasons .

Disable Encryption​Prerequisites:​
Unlocked Bootloader and FRP
adb and fastboot installed on pc
Official TWRP
Stock recovery_ramdis.img
Notes:​You can disable encryption at any step, even after booting, but in order to disable it you have to do a factory reset from stock recovery_ramdis. Because of this I recommend doing between flashing gsi and flashing gapps.
Steps:​
Get the Prerequisites
Boot to TWRP (power + vol+ after shutting down)
Allow modifications
Press Mount, select Vendor
Connect phone to PC
You can do next part 2 ways, if you're good with command line interface use steps 7 through 11, if not skip to step 12
Type adb shell and press enter
Type nano /vendor/etc/fstab.hi6250 and press enter
Remove fileencryption=aes-256-xts:aes-256-cts part from 16th line, make sure there's only one comma between check and reservedsize
Press Ctrl + X then Y and press enter
Go to step 18
Type adb pull /vendor/etc/fstab.hi6250 and press enter
If you have adb in your $PATH go to your user profile folder, if not go to folder where adb.exe resides
Open fstab.hi6250 via a text editor (please use notepad++)
Remove fileencryption=aes-256-xts:aes-256-cts part from 16th line, make sure there's only one comma between check and reservedsize
Save file and open a command prompt
Send this command adb push ./fstab.hi6250 /vendor/etc/fstab.hi6250
View attachment 5422531
Now you need to do a factory reset with stock recovery_ramdis.img, if you have it installed go to step 21 if not do 19 or 20 first
If you have recovery_ramdis.img in your sd card, press Install and press Install Image then select and flash stock recovery_ramdis.img to recovery_ramdisk partition
If not shut down phone, connect it to pc and hold down vol- until you're at fastboot, then write this command fastboot flash recovery_ramdisk and drag recovery_ramdis.img over to console then press enter
Shut down phone and unplug it from pc
Press and hold power+ vol+ until you see short yellow warning
Press Factory Reset and type yes
You've successfully decrypted your phone and you're good to boot up or flash gapps
Getting Stock Firmware Files And Downgrading​Prerequisites:​
Unlocked Bootloader and FRP
adb and fastboot installed on pc
Huawei Update Extractor
Firmware Zips
HiSuite
Erecovery
EMUI's System Updater (via root)
HuRUpdater Guide / HuRUpdater Download (don't work anymore)
HwOTA (don't work anymore)
Getting stock files are problematic because of huawei. Least shadiest way to get them are the hardest so bear with me.
Androidhost.ru : Click the "Firmware Zips" from prerequisites and search p20 lite. You should get a wide variety of versions to pick from. Make sure to match the Cust in the file to yours. C432 for Europe for example. After you download the zip file open it up and find a folder named "dload". You can either get this folder and paste it right into your sd card to force dload or you can open this folder and extract update_sd.zip. Inside update_sd.zip you'll find a file named UPDATE.APP. Use Huawei Update Extractor to open this file and there you'll see all the partitions you need. If HUE gives error while opening it, go to settings and untick "Verify file checksum". You can extract .img files by right clicking and selecting extract option on each partition. Normally you can't open these .img files but after pushing them through simg2img you'll be able to explore them too. But lets be real if you need guides for this, all you need is recovery_ramdis.img.
Using Dload Folder : Your sd card can't be FAT32 for this. FAT32 by nature don't allow files larger than 4gb so you can't get this folder to your sd card. Format it to ExFat via any guide on the internet then copy the dload folder to your sd card's root. It can't be inside any folders. Then shut your phone and press Power + Vol+ + Vol- all at the same time. It'll boot to erecovery which'll check the integrity of files then install them regardless of your EMUI version. So it is a good way to downgrade. Keep in mind tho you can't dload back to emui 8 from emui 9. And any successful dload will lock your bootloader back.
Hisuite : You can actually get firmware files pretty easily with hisuite but it requires real work. You see, hisuite downloads firmware files right into your documents folder. Connect your phone to pc and open up hisuite. Check for updates and if it finds one it'll download following files update_full_base.zip, update_full_ANE-L01_hw_eu.zip and update_full_cust_ANE-L01_hw_eu.zip. You only need update_full_base.zip file, others are used to work on HuRUpdater and HwOTA but they are deprecated since February. Inside update_full_base.zip you'll find UPDATE.APP which you can extract images from with Huawei Update Extractor.
Erecovery : This one requires some network knowledge and it'll only get you the latest version so I don't think it worth the hassle. You need a router that allows you to change dns address for DHCP clients. Which most of them do these days. Now you need to create and run a dns server on your pc. I recommend adguard home. Pihole works too. Use Windows Subsystem For Linux or Docker to install either of them. Once you get them up and working set them to log dns requests. I believe you know where this is going. Open your router's interface and enter adguard home/pihole ip address which maps back to your pc's local address. Check if it works or not by opening up few sites on your phone which should be connected to your wifi and isn't set up to use a different dns server. If all is good open up erecovery on your phone and connect to your wifi. If you set it up correctly it should get the latest version from huawei which will show up on your log. Use that url to download it to your pc and extract it same as others. There was a paid service that used this method to send specific versions to your erecovery.
EMUI's System Updater : This is tricky and my favorite. Get the official TWRP .img and patch it with magisk manager. Then flash it via fastboot. I know, "twrp and magisk? wtf?" just do it. It takes a long time to boot but it works don't question me right now. After you get root in EMUI allow system updater to do its job and update. It'll ask to reboot, allow it. It will throw you back to system after reboot cuz recovery is hijacked. duh. Get a file manager that allows root access. Allow system updater to download again. But this time do not allow it to reboot. First one downloaded OTA, second one downloaded FullOTA. Which is better for archival purposes. After download is done search for a folder named HwOUC in /system. Copy it to internal storage and from there to your pc. You can find our main UPDATE.APP inside update_full_base.zip. Other zips include cust and all that which HuRu and HwOTA used to require.
Magisk​Prerequisites:​
Unlocked Bootloader and FRP
adb and fastboot installed on pc
Stock recovery_ramdis.img
Notes:​Officially speaking magisk support for our device is dead. Magisk decided to retire magisk-in-recovery method which our phone uses. But hey it is still working without modifications unlike a-only devices so that's a win. As a foot note, you CAN use twrp image instead of stock recovery_ramdis.img but it'll take longer to boot. Using .380's recovery_ramdis.img on .278 build will not work. Make sure to match your EMUI build with ramdisk you're flashing. Ask me how I know.
Steps to install older version:​
Get the Prerequisites
No, I mean literally just get the Prerequisites and thats it
Open up your browser and find a bin service (pastebin will suffice)
Create a paste with following
Code:

}
Get the paste's raw url
Take the recovery_ramdis.img to internal storage
Install magisk manager 8.0.7
Open it's settings and select custom channel
Write the raw url you just created
Allow it to check for updates and it'll find that 21.4 is the latest version
Click install and select recovery_ramdis.img
After it finishes patching get the magisk_patched.img to your pc
Get your phone to fastboot mode
After connecting to pc, write this fastboot flash recovery_ramdisk to console and drag magisk_patched.img over to console and press enter
Now if you enter recovery it'll boot to android with magisk but if you boot normally it will not detect magisk so each time you restart you have to use Power + Vol+ combo in order to get magisk
Remember to switch custom channel to stable channel if you want to receive updates.
I know that you can pretty much reduce the amount of flashing and restarting by flashing twrp to erecovery but since erecovery is a lifeline for most people here I decided not to get into that. But for those who are interested check this thread.​

Oh, man! Are you serious?

I don't know what anyone expects from a guide... Is it better to just repeat the same thing over and over again? "Flash system with fastboot, factory reset with stock recovery, flash and boot twrp, resize system, flash gapps" is literally the summary of this. That summary is what you'll get as an answer if you ask for help on any telegram group. Instead of saying flash twrp, I wrote how you can flash twrp. Thats why it's so long. This guide is for "how" not "what".

I would say that even so far, people have managed to install GSI, Magisk, etc. .
Btw, Recovery and eRecovery are the same for all models and build numbers . They are even compatible with LLD and BND models.

Frax3r said:
Thats why it's so long
Click to expand...
Click to collapse
It is long because because of procedures that are too complicated, e.g. chapter "Disable Encryption" .
It is long because of duplicate procedures, e.g. chapter "Flashing Any GSI".
Sorry but Chapter "Magisk" is useless. Nowadays nobody needs to install the old Magisk. Rather focus on some of the nuances of installing Magisk on EMUI 9.1 that would be helpful.

Hello there! Alive parts of this forum is still filled with simple help requests so I decided to put together a simple all-in-one thread that basically covers most stuff. I don't wanna get into bootloader unlocking because right now only free way to do so is with potatoNV which I do not know how to use. Dc-unlocker is an option too but it is 4€ so pick your poison.
I have uploaded all my resources for this device to here. Inside EMUI folder you'll find some of the versions that I archived with the methods I explained on getting firmwares section. You can find recovery_ramdis.img from each of these version inside RECOVERY_RAMDISK folder as well.​​Special key combos:​
Power + Vol+ = Recovery Mode​
While USB connected, Power + Vol+ = Erecovery Mode​
While USB connected, Vol- = Fastboot​
Plug USB while holding down Vol+ + Vol- = Download Mode​
Power + Vol+ + Vol- = Force Dload​

People use gapps versions because they don't want to waste time by flashing zips. That's why it's 2 part. Gapps one is shorter.

Magisk-in-recovery as in "magisk hijacking recovery" not "installing magisk using recovery". You can't even find huawei section in it's installation instructions. Look here and here. As for the nuance you asked, installing magisk in EMUI is literally same as installing it in GSI or LOS. You patch the image, flash the image, boot the image.

I added "ask me how I know" part for a reason. I tried. You CAN patch official twrp with magisk and it WILL boot. If a person unlocks their bootloader for the first time how is he supposed to get stock recovery_ramdis.img? Get the mmcblock of recovery_ramdisk? How is he supposed to do that if he flashes twrp over to recovery_ramdisk partition? We can't use "fastboot boot" so that's out of option. Use a different recovery_ramdis.img you might say. I TRIED. .380's recovery_ramdis.img patched with latest magisk won't boot if you're at .278. I created a folder where I patched .380 recovery with each different version of magisk starting from 20.4 up to latest version and none of them booted on los 16 which was installed upon .278. It is not universal as you might think.

Care to elaborate? I am open to constructive criticism. As for what I know, I do know that you won't find yourself bootlooping if you follow these steps by the letter. I saw your instructions on los 16 and other threads too. Here's a criticism for you, do not tell people to wipe /data or factory reset with twrps and especially do not expect them to flash twrp over to erecovery. Wiping /data or factory reset from twrp always resulted in phone freezing for me. I guess twrp in erecovery could fix freezing but there's a reason why they are asking for help and you expect them to overwrite their only lifeline. 1-2 extra rebooting and flashing won't hurt anyone. When you wipe /data or factory reset with most twrps, including official one, some folders that needs to be untouched (huawei am i right) gets deleted. So you have to use stock recovery_ramdis.img or an advanced twrp which compansates it. Check the tishserg's twrp for example. I use that not the official twrp for these things. And it can write to erecovery which is exactly why I didn't advocate on using it in this guide. Have a good day...

Use recommended TWRP, not 3.4.0. and above, which is not fully compatible with hi6250 devices (including official one). Did you know?
Btw, I never advised anyone to do a factory reset in TWRP, on the contrary

Yes you said that here. However my own experience says otherwise. Before my current los 16 installation I used official 3.5.2. Flashed los, flashed stock recovery, flashed phenix kernel, flashed gapps all from it. I even used nano from adb shell to edit fstab.hi6250. I used backup and restore only on kernel partition but it was successful anyway. What that incompatibility be? Is it boot override thing? If you have twrp in recovery and send reboot to recovery from android it just keeps booting to twrp in each reboot even tho you select otherwise from twrp's reboot menu. BTW tishserg's twrp have an option to remove that override if you find yourself in that loop. As for factory reset part, you said format /data here. We had a discussion here because of that. My bad on reading wrong. While writing this I realised incompatibility is probably about formating /data on twrp 3.4.0 and above. If that is the case I'll update the post. Good thing I didn't tell people to format /data from twrp. My steps might be long but they are correct. It is wrong to call all this a nonsense.
Everyone might know it is possible to install latest magisk but not everyone knows how to install an older version now that magisk's future is uncertain. After magisk removes magiskhide from its code people are gonna wanna go back to latest version that worked while waiting for module version of it. Patching twrp image with magisk is highlight of this post but it is literally what flashing magisk.zip (.apk to .zip) from twrp does with the latest version. If patching twrp is bad then why is my guide to installing an older version, which allows you to select which image to patch, is the target? + With that .json, you can make magisk manager patch the image with your own modified version of magisk should you upload it somewhere and change the links.

Hi,
I'm building trying to port Ubuntu Touch to this device and I'm running into a few challenges. I have already reverted to stock 2 times and re-unlocked the bootloader (starting from EMUI 9). So far I have only flashed recovery_ramdisk with twrp as I was worried I might not be able to revert to stock if I flashed erecovery.
Question 1: Is this correct or a misunderstanding?
Installing Ubuntu Touch requires the data partition to be formatted to ext4. I can do that from twrp, but someone (maybe you) wrote that wiping the data partition with twrp was liable to create trouble.
Q2: Same question as above.
I understand Huawei requires the kernel and ramdisk to reside in separate images on separate partitions. So I have used this guide (https://wiki.postmarketos.org/wiki/Huawei_P10_Lite_(huawei-warsaw)) to separate the boot.img produced in my build, and then flashed these two image files to the kernel and recovery_ramdisk partitions respectively. However, examining the LOS 16.0 rom that can be installed, I see that it contains a "boot.img".
Q3: Can I flash my boot.img without separating into kernel and ramdisk first, and if so, which partition should I flash?
Q4: After flashing the image files I built (kernel.img and ramdisk.img along with system.img), do I need to reboot to a recovery (if so, which?) and wipe something (if so, what?) before rebooting?

Hello,
If I understood you correctly you're asking if you can flash stock erecovery after you've modified it. Answer is yes, you can flash twrp on it and when you're done you can flash stock erecovery image over it. Fastboot won't allow you to flash anything on erecovery partition tho. So you need to use certain twrps that are capable of flashing over erecovery. s_mak and tishserg twrps should allow that iirc. First flash any one of those twrps to recovery_ramdisk then boot into it afterwards flash same twrp image to erecovery partition from inside the twrp.
Yes, if you look at last few replies in this thread that was exactly the conversation. However that is only the case with official twrp. If you use s_mak or tishserg's twrps from the mega link in the thread you should be able to wipe without a problem.
Last 2 questions are beyond me I'm afraid. PostparketOS and Ubuntu Touch are inherently very different to android and they could require some stuff that are unique to them. However I would imagine you wouldn't need to wipe anything after flashing those images.

Misunderstanding. You can revert to stock via eRecovery & wi-fi.
Huawei has Recovery and eRecovery, each has different functions.
You can use the following combinations in your phone:
- Recovery + eRecovery (stock FW)
- TWRP instead of Recovery + eRecovery
- Recovery + TWRP instead of eRecovery

Same answer as above. Formatting (not wiping) data with TWRP 3.4+ is dangerous (running stock EMUI).
Q3: All this only works on EMUI 8 as far as I know.
Q4: follow the instructions, imo.
P.S.: as you can see, mobile Linux projects such as Ubuntu Touch, postmarketOS or Sailfish OS work only partially on Hua/Ho phones,but we already talked about that .

Re-reading your answer above, I see I'd like to double check: Is this dangerous only if you are running stock EMUI, or would it also be dangerous to use TWRP 3.4+ to format the data partition when you wish to run a different system on the device, as in my case?

Hard to say, no one has experience with different system . But I don't think it matters - see Mr. Frax3r's post above (and read carefully bro ).

I'm bumping the thread, few improvements are made for android 13.

Thank you for the update.
I have modified Phenix_4.9.235-phenix-1.0 rebased on Harmonyos to make it permissive which make most A13 GSIs boot normally on my phone. I have attached the updated one.

How To Guide Install GSI Image to A54 5G (Compatible with all devices with OEM Unlock toggle)

First of all, download the firmware for your device. I use Samsung firmware downloader (https://github.com/zacharee/SamloaderKotlin)
In the model section, put your device model (If you don't know it, go to settings, about phone and below your model name, there should appear a code next to "Model number" Example: A546B)
In the CSC section, put your CSC. (If you don't know it go to settings, about phone, Software information and search for Service Provider SW Ver. You may find 3 or more 3 letter codes in it, the one we care about is the first one. For example, for me it's "EUX/EUX/-/EUX")
Now, click on "Check for updates" and then "Download". It will take a while, so leave it for 5-10 minutes depending on your internet speed.
Now, we will need to unlock the bootloader. If this is your main phone, backup data if you really want to custom ROM it, because it will erase all data. First of all, we will need to shutdown the device. Now, when it is fully off, we will press both VOL + and VOL - keys and connect a cable from the phone to our PC. Now, you should see a light blue screen with a bunch of text. Now we need to hold VOL+ key for 5 or more seconds, and press the vol+ key when the text changes.
Going through the setup is not necessary, as we will need to factory reset later on.
Now, check the folder where you told the program to store the firmware in and extract the folder. In it, you will see 5 files that end in .tar.md5 (CSC, HOME_CSC, CP, BL and AP), the one we care about is AP. Open it with winrar and extract the "recovery.img.lz4" file. Now, install lz4 (https://github.com/lz4/lz4/releases).
You can add the folder to path, but it's optional. Now, open CMD/Powershell and go to the directory your "recovery.img.lz4" is stored. Now run this command: "lz4 recovery.img.lz4 recovery.img". After that, you should get the recovery.img in the same folder.
For this step, we will need a github account, so go to github.com and create an account. Now go to https://github.com/Johx22/Patch-Recovery and fork the repository (the button is at the top right). Now we should be in our fork. Click on the "Actions" button below the repository name and click "RECOVERY". Now, we will upload our image to transfer.sh and get the link it gives us. Click on run workflow, and put the link transfer.sh gave us. Wait a minute or so, and we should get a file named "Patched-Recovery". Download it. Now, extract the file and we should get "fastbootd-recovery.tar".
Download odin https://odindownload.com/SamsungOdin/ and open it.
Now we will get the phone on the same mode as before (the blue screen), and instead of holding the VOL+ key now, we will press it once. Now connect your phone to your pc and click the "AP" button on odin. Select the file we got (fastbootd-recovery.tar) and click "Start".
Now, this is very important, when the bar finishes going to the end, and the square above says "RESET", we will need to hold the power key+VOL+ key. If we don't, the recovery will the rewritten and we will need to flash it again.
Now we should be in recovery mode.
Now, there should be a new option: "Enter fastboot mode"/"Enter fastbootd". use volume keys to move and when you are on "Enter fastboot mode", click power key.
Now, download platform-tools, i already provided them in the thread. Unzip the file and open CMD in platform-tools and now it's time to download a GSI image.
There's many GSI's but pixel experience is my favourite. As of now, the latest working GSI of pixel experience on samsung devices is this one: https://github.com/ponces/treble_bu...Plus_arm64-ab-13.0-20230421-UNOFFICIAL.img.xz.
Uncompress it and move the image to platform-tools. Now, we run this command on CMD: fastboot flash PixelExperience_arm64-ab-13.0-20230104-UNOFFICIAL.img, and wait till it completes.
Now click "Enter recovery mode" and click Wipe Data/Factory reset and after it completes, restart to system. You should see a google logo now.
Enjoy!

are you running a gsi now? do you mind telling me if you saw any audio degradation when using gsi on your a54?

Updated latest compatible PE GSI build

I'm still getting error during building patched recovery, do you mind upload your patched recovery?
Thanks a lot!
