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

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 )

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

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:

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.

Moto G7 Power/Supra [All Versions] [Pie] Magisk Root Guide [OTA/SafetyNet Working]

Disclaimer: This WILL void your warranty. I am not liable for breaking/bricking your phone, you losing your data, or any nuclear war/other catastrophe. This process WILL totally wipe all data on your phone. Make sure you have a backup! You will also forever see "bad key" displayed in the top left of your screen for a few seconds after a reboot after unlocking the bootloader. There is currently no way around this that I'm aware of (let me know if you have a way)
This guide was assembled from mingkee's G7 guide here: https://forum.xda-developers.com/moto-g7/how-to/root-g7-magisk-t3907084
You will need:
1. Your Moto G7 Power (Any hardware version, any carrier, but running Android 9 Pie)
2. A stock boot.img for your hardware version, here are the two that I have. You can just extract the boot.img from a stock ROM for a hardware version not listed, although I'm not sure it actually matters which one you use. Experiment at your own risk.
XT1955-5 US: https://mega.nz/#!L0sHzSKY!323GrDQ8BTsPmKvrSoU7DV-2kJuVris0cWN8Xt3u_6o
XT1955-2 LATAM: https://mega.nz/#!uk912I4B!12_EgPML2l5sIXDeDGVqiVDB2RwA6iF6-H-mivNecOo
(Full stock ROM's for both versions will be linked in the next post. )
3. A USB cable to connect your G7 to a computer
4. Motorola USB drivers: https://support.motorola.com/uk/en/...moto-g-family/moto-g7-power/documents/MS98028
4. Your bootloader unlock code from Motorola, more on that below
5. Android SDK
Step 1: Unlocking the bootloader
First we'll need to unlock the bootloader, to do this, you'll need your unlock code from Motorola:
https://support.motorola.com/us/en/bootloader
Note that this will require you to register your device with Motorola, and this WILL void your warranty.
Then, download and install the Motorola USB drivers (link above), you may need to reboot your computer after installation.
Next you'll need to download and extract/install the Android SDK
https://developer.android.com/studio/index.html#downloads
Note that you'll only need the "command line tools" for this guide, unless you really want the whole SDK (huge).
Extract the command line tools to anywhere really, C:\Android is fine for Windows. If you downloaded/installed the whole sdk, the tools you need will be in C:\Users\[your username]\AppData\Local\Android\Sdk\platform-tools
Once you have that, open up a powershell window in your tools folder by holding Shift and right-clicking in the folder.
Now, reboot your G7 to fastboot mode by powering off, then holding power+volume down until you're in the bootloader. Now, connect your G7 to your computer with your USB cable.
In powershell, verify your device is recognized by typing "./fastboot devices". Your G7 should show up by its serial number.
Now, type "./fastboot oem unlock [your motorola unlock code]". THIS WILL WIPE ALL DATA ON YOUR PHONE. After that, use the volume up and down buttons and then the power key to restart the bootloader. You should now see "flashing_unlocked" at the bottom of the bootloader screen. Now use the volume/power buttons to select "start" to boot the phone. You will see "bad key" displayed in the top left corner of the screen. This is normal. The phone should boot and bring you to the Android set up wizard. Go ahead and set up the phone as you normally would.
Note that at this time, if you go to "Update" in system settings, it may warn you that "system integrity is compromised" and that you will no longer receive OTA updates. This is also normal, we'll fix that in a bit.
Step 2: Rooting
Now that we have an unlocked bootloader, we can flash things to the phone through fastboot (at the time of this writing, TWRP or other custom recoveries are not available for the G7 Power. Once it is, you can use that to flash the Magisk .zip file instead of using powershell).
Copy the correct *_boot.img for your hardware version to a folder on your phone. I used the downloads folder. (not too sure if the version makes a difference; I was able to flash the entire US XT1955-5 firmware/rom to my Latin America XT1955-2 without a problem, but experiment at your own risk)
Download and install the Magisk Manager APK through Chrome or browser of your choice on your G7
https://github.com/topjohnwu/Magisk/releases
It will ask you if you want to allow [your browser] to install things from unknown sources. Say yes.
Then, open Magisk Manager and tap "Install". Then tap "patch boot image file". Select the *_boot.img you copied earlier and let it run. It will tell you when its done.
Once it completes, copy the patched *_boot.img back to your computer and place it in the same folder as your Android SDK tools (where fastboot.exe and adb.exe live)
Now power off the phone then boot to fastboot, again by holding power + volume down until the bootloader appears.
Now in powershell, type "./fastboot flash boot [the name of your patched boot.img].img" and hit enter. Alternatively, type "./fastboot flash boot" then hit space, then drag your patched *_boot.img into powershell and hit enter.
(Note, if you get an error saying "Invalid partition name boot__a" like I did, add a "_a" to "boot" ie "./fastboot flash boot_a [the name of your patched boot.img]" instead. )
Powershell should tell you "Image signed with key bad key". This is normal.
Now use the volume up/down buttons and power button to start the phone.
Once booted, load up Magisk Manager again. You should see all green checkmarks. Congrats, your G7 is now rooted! One last thing:
Tap where Magisk says "tap to start SafetyNet check". This tests to see if its able to fool Google's checks and let you install OTA updates or use Android Pay. If you did everything properly, this should all check out fine. Confirm by going into Updates in System Settings and verifying that you are up-to-date and it doesnt say anything about "device integrity compromised".
Thanks to everyone who's work I shamelessly paraphrased. I wanted to make a concise guide specifically for the G7 power as I didn't find much online regarding it. (And the stock US rom was ridiculously hard to find and acquire). I'll link stock US and Latin America G7 Power firmwares/roms in the post below in case anyone wants to go back to stock, once the upload finishes. Note: there is no known way at the time of this writing that you can ever get rid of "bad key" being displayed at boot once you unlock the bootloader (again, if anyone knows how, let me know! Thanks!)

gedster314 linked me to a site in another thread where stock ROMS for a lot of devices can be found, including the XT1955 (codename: Ocean).
https://mirrors.lolinet.com/firmware/moto/ocean/official/
"RETUS" on that page would signify "Retail, US"

Baby steps my friend.

Their are still reasons to Root a phone besides ROMs. Titanium backup, Root explorer, and having super user
access. I used to Root my Pixel 2 to enable tethering when the carrier blocked it. The fact that we don't have
the option of super user access on a device we own is crazy. Jailbreaking the iPhone opens up so many
customization's with tweaks and apps that I went to the dark side. I also have the G7 Power so I'm not a
total traitor.

I've tried that. Flashing the XT1955-2 with the XT1955-5 firmware. It flashes and boots up without a problem but no dice for the 5Ghz. I have gotten ALL LTE bands unlocked however, about to write up a how-to. If I can get 5ghz wifi working then the XT1955-2 will be the cats meow with its 4gb ram and dirt cheap price.

Perfect. How about NFC? Does the XT1955-2 come with NFC already enabled? Or does the -5 enable it?

I was wrong in my first thread, my -2 does NOT have NFC. Heres the newly minted LTE Band unlocking guide: https://forum.xda-developers.com/g7-power/how-to/guide-moto-g7-power-supra-enable-lte-t3925246

Try rolling back to stock with my other guide. Then try again.

Thanks for the guide, phone is now rooted. Is it safe to do a factory reset to be able to start the phone set up again to automatically download apps, settings, etc from Google? If not, is there another, better way to do that?

PLZ HELP!!!
before if found this thread, I unlocked the bootloader then i saw a magisk boot.img in another website that works with xt1955-5 & 1955-6 and hwen i flash it it said "Imaged signed with bad key bad" and when i reboot it bootloops between the "your device is now unlocked" and the motorola logo
This is my first time working with fastboot
i worked with EDL but not Fastboot
But after some research I FOUND out that i could have used "fastboot boot boot.img" before actually flashing it but I WAS TOO LATE.
ANY HELP
APPRECIATE IT SO MUCH
And i just bought this phone yesterday

You could try to flash a stock firmware with diversenerd's guide
https://forum.xda-developers.com/g7-power/how-to/guide-moto-g7-power-supra-flash-to-t3927138
And try to root again,
Also, I tried to "fastboot boot boot.img" and it does not work, dont blame yourself for that

[SOLVED] Help Flashing Lineage OS

EDIT:SOLVED -- READ BELOW:
I finally got it flashed by following a few guides here which I will link, and try to break it down easier for someone else to come across and follow. I thought I bricked my phone (flashed LineageOS then rebooted, phone did not show anything on screen, full black screen) but after following a few guides I got it solved.
If you get bricked, or just want to follow a clean perfect install, please start below (Skip to step 2 if you are starting fresh, if you have soft-bricked your device start from step 1)
1. Bricked it and had to execute QDLoader 9008 fix again.
Tutorial is easier than it looks, do not fear, if you have soft-bricked your device and see a black screen, go ahead and go through the qdloader brick solution.
2. From factory recovery updated to Version WW-16.1220.1909.193.
If you have started fresh, I would highly recommend updating to the more updated firmware first. For me this worked, and I suggest updating to get a more current kernel, which may play better with Lineage OS install. To install a newer stock firmware linked above, download the ~2GB Firmware above, and save it to your Minimal ADB / Fastboot folder. Power off your device, after it has been successfully restored (if you bricked it) or you want to start off fresh and get the install right the first time. With your device powered off, Hold Volume UP and then Hold Power Button until the Fastboot menu appears. Use your volume keys to select Recovery, then press Power button to enter the STOCK Recovery (we are still on stock firmware with stock recovery). When in stock recovery select install from ADB. We are going to push the install via ADB (I tried dragging the firmware to the internal and selecting install ZIP and that didnt work).
Go into your Minimal ADB / Fastboot folder on your computer and open command prompt by holding Shift+Control and Right clicking and then selecting open command prompt here.
Now, enter the following command in the command prompt and hit enter:
adb devices
This command will show if any fastboot device is connected. If it doesn’t show, then please check the drivers are installed properly and try again.
If your device is listed, then type the command given below and press enter:
adb sideload File_name.zip
^^This will be the ~2GB Firmware file downloaded above
Wait until the installation process completes.
Once the installation process is complete, restart your device.
Done. You have successfully upgraded the Asus ZenFone 6 to the newer firmware, please continue.
3. Downloaded OTA 16.1220.1909.193 to 16.1220.1909.194, renamed it to UL-ASUS_I01WD-ASUS-16.1220.1909.194-1.1.1-user.zip and placed into root of internal memory.
When I disconnected USB cable (or rebooted, not sure), I was prompted with update notification. I have updated it. Either way, reboot your device if you don't see the notification, and look in your notifications to see something saying: System Update Detected Proceed with Update - and select it and update.
4. Now that your phone is 100% Updated with the newest firmware, let's follow another guide I found here:
I assume you're on a fresh Android 9 stock ROM, or just finished restoring your phone with the Flashall_AFT.cmd from this tutorial.
You should at least boot once on the system, and disable any PIN or password to unlock your phone (hence putting a default password for the FBE).
Download the latest OFFICIAL TWRP.x.x.img (which we'll use to boot on it), and it's installer to install it later (TWRP.x.x.zip) if you want to use it.
LineageOS installation steps :
Reboot to bootloader (=fastboot mode), connect to your PC and boot on TWRP :
Command:
fastboot boot TWRP.x.x.img
Once on TWRP, you can see that we're on slot A (Menu > Reboot). Now go to wipe > factory reset and then wipe system (technically I suspect this only wipes slot A, but do it anyway, don't worry about the errors!)
Now go to Install > flash the newest official LOS_latest.zip. What happens here is that the LOS installer will flash LOS on the inactive slot (slot B in our case). And will also install the LOS recovery (on both slots it seems).
Reboot to recovery : your phone automatically switches slots and will boot the LineageOS recovery (Don't fear, we don't need TWRP right now, just go along with this step) on slot B.
On the LineageOS recovery, do factory reset (which seems to be a full /data format in fact, thus removing any previous encryption AND all your data on internal storage). If you want to use Magisk, go to the recovery's install menu and sideload it now
Use code:
adb sideload Magisk-v20.3.zip
Now reboot to system. It might take a while (one or 2 loops in my case), but your phone should boot, or in some cases will end up on LOS recovery asking for a 'factory data reset' (then do it and reboot again).
Once booted on your LOS rom, you can define a pin or password to lock your phone (that'll be the FBE decryption password).
Now if you want to use TWRP, reboot to bootloader and boot again on TWRP.img (step 1)
From TWRP > Install > flash TWRP.x.x.zip (that is, the TWRP installer). It installs on both slots by default. If you had installed Magisk, you have to flash it again (because anything modifying the boot.img - like the TWRP installer in our case - will erase it).
You can now reboot to system and enjoy LOS

Thanks for the nice documentation. I've recently also struggling with installing a custom ROM and this clears some things up.
Wanted to ask, if you also have the audio issue that 1) callers hear an echo of themselves, and 2) the bottom speaker is active when receiving a call?
Thanks.

Haven't actually put my sim in yet to make calls, will let you know later today, sorry about the delay!

I had previously attempted this a number of months ago, and managed to soft brick my Zenfone 6 several times, eventually kind of giving up and just using the stock firmware.
I tried again back on Memorial Day in the US. This time around, I bricked it hard. Could not get device to power on in any fashion. PC would not "see" USB connection at all.
I returned it to ASUS for service, and they've charged me a little over $200 to repair it. The only problem they noted was, "Device is rooted/unlock". So I have no way of knowing if their diagnosis is based on actual inspection of the device, or if they're just replacing the SOC on the basis that I used their official bootloader unlock tool, thus registering my phone's S/N.
Just a little caveat emptor for anyone attempting to use this guide. I was able to get TWRP to load, and succesfully updated the stock firmware, but any and all attempts to load the Lineage image failed.
Eventually one of them soft bricked my phone as before, and I think my mistake was interrupting the soft brick rewrite procedure by prematurely unplugging my phone from the PC.

I had a similar issue: Bricked and totally unresponsive phone (or so I thought until I realised the screen was flashing very faintly when I switched off the lights - I could only tell in the dark due to how dim the flashing on the display was) where de "Powered by Android" logo kept flashing for a millisecond and in a loop. None of the button combinations worked so I couldn't switch completely off, access recovery/fastboot, and my computer wouldn't recognise the phone when I connected it via USB. I ended up buying an EDL cable for deep flashing Qualcomm phones (€9) and within minutes I was back up and running. All solved.

I bought it from Amazon. The one I bought is out of stock now, but there are a lot of them available (from other brands/sellers). This one for example - is the one that most resembles the one I actually bought: https://www.amazon.es/ASHATA-tel%C3%A9fono-reparaci%C3%B3n-Adaptador-Engineering/dp/B086WZMFKW/ref=sr_1_18?__mk_es_ES=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=cable+edl&qid=1597417614&sr=8-18

Since the thread is already on topic, could I flash lineage os while being on a custom rom? I have Bliss ROM on partition A and stock on B. Is it possible to have both Bliss and Lineage in dual boot?
Also, maybe a little off topic, the partition A/B scheme was intended to be used as a dual OS boot like normal PCs? Because right now I can select A and boot Bliss, select B and boot stock, I don't get why the procedure for flashing Lineage OS is so convoluted(requires having stock both on B and A?!) since both partition seems to be standalone and separated from each other.

The cable itself (on its own), doesn't seem to "do" anything, but is paramount in reaching the right area, in order to fix the problem by means of the appropriate instructions and files. I can't recall where I ended up getting the right instructions from - as I researched quite a bit, and did a lot of "trial an error" before getting it right - so I'm sorry but I can't refer you directly to them via link (so that whoever posted them originally gets the credit they deserve), but this is what I ended up doing (on a WINDOWS machine) based on said instructions:
DOWNLOADS:
- Qualcomm drivers: https://androidfilehost.com/?fid=11410963190603857508
- Firmware with scripts: https://androidfilehost.com/?fid=1395089523397969054
- Latest official ASUS firmware from the ASUS webpage (download and place it in a memory card)
- (If you don't already have it on your WINDOWS machine): download and install Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package
PROCEDURE:
1- Install the Qualcomm drivers
2- Unpack the downloaded firmware containing the scripts
3- Place the memory card in the phone's slot (with the latest official ASUS firmware already in it)
4- Power off the phone by VolumeDown + Power buttons (keep them pressed for about <25 seconds)
5- Connect the phone to the computer via the EDL cable and press the button on the EDL cable (there was an extra bit on what to do with a archive from the drivers file if your computer doesn't recognise the port straight away, but it wasn't necessary in my case so I didn't keep that step/archive name in my notes... I'm afraid you will have to search for it like I did if you come across that issue).
6- Start update_image_EDL.bat script from the unpacked firmware
7- After the script in step 6 finishes, start script flashall_AFT.cmd
8- Start bootloader
9- Go to stock recovery mode and install the ASUS firmware from the memory card
X- (Instructions also suggested to repeat steps 8 & 9 again at this point - for a second time - but in my case it wasn't needed)
I hope this helps.

Hey buddy, I appreciate your reply. The cable is on its way but I got a bit fiesty and opened up the phone to short the two contacts. This did the trick for me, got me back into EDL mode, and I was able to flash the latest firmware. On that topic, I'm trying to find the most suitable firmware version to run LineageOS 17 on the phone. I grabbed Mauro's TWRP to temporarily boot into which allowed me to flash the latest Asus image from their site. I guell I'll just carry on from there.

As far as I understand, that's pretty much what the cable does actually... I also came across that method along my research, but I didn't want to risk opening the phone up. Since you are in the "flashing state": be careful with some of the instructions out there - I flashed through TWRP as I have been doing all these years with other phones, following specific instructions for each ROM I've tried, and I had nothing but issues until I flashed through ADB. I still don't know why I was getting the "No OS" warning all the time despite flashing correctly from TWRP (contemplating the A/B partitions matter), but none worked...

Appreciated but I'm all sorted. I believe my pitfall was not using the copy-partitions .zip file detailed in the instructions. I had no idea that was a thing. Was extra careful this time and now I'm on the ROM I need.
I ****ing hate A/B partitioned phones, makes custom ROMs such a chore. Sort of getting fed up with phones in general but at least this is working well for now.

Same here. It was so easy to do the Samsungs "back in the day", and you always had ODIN as a fallback if things went south. But this "A/B" partition nonsense (as well as other useless changes they introduce every time they "upgrade" Android, or certain structure modifications every so often when a new phone comes out) are a pain in the butt! Changes clearly aimed at making things more annoying/difficult for us people who don't want standard/corporate/unnecessarily bloated phones... Actually (as a former Blackberry user) I was tempted to get one of these Android based Blackberrys (the KEY2), but I didn't in the end precisely due to the fact that the bootloader can't be touched, and it can be rooted...

I want to switch to because the latest security update (August 2020) by Asus is soft bricking the phone for many users,
but I am seeing a few reports about some bugs (like the phone is stuck in the lineage boot symbol and cellular errors) in lineage os and also seeing few post with a lot of installation errors (like soft and total bricking) etc. and for me in developers options I'm not seeing the OEM and advanced boot options.(in my asus stock os) I just found out that I have to download the Unlock Boot loader apk separately from asus and install it using command prompt so I don't know how to proceed.
Can you please elaborate on how you actually did it with your Asus Zenfone 6(2019), I am a total noob in this and I also couldn't understand the partition a and b parts too.

Guide LG G8/G8x/v50 Bootloader Unlock and Magisk Root using Firehose by Seasee606

I gave up on unlocking the bootloader of my V50 sprint version because I thought it was impossible. Not until I stumbled upon this guide in the LG G8 forum.
I think it is good to have the information in the LG V50 thread also. The thread is owned by Seasee606.

I'm on xda so I don't have to resort to telegram. we've been over this.

I ve just done it on my V500N
took me about 2 hours so not so easy but not impossible
maybe I was lucky ?
couple of difficulties :
* first I could not get into EDL mode but I took the LG USB cable from the box and this worked
* the first time I exited the QFIL partition manager the phone rebooted to EDL mode but was not recognized as "qualcomm device" (there was an unknown usb device in the device manager) ... I just manually rebooted into EDL mode and the phone was recognized as "qualcomm device" this time and I could continue the method without issue ...

(deleted) (see below)

pierro78 said:
nice (and strange !) surprise :
* after bootloader unlock I was supposed to enter "fastboot flash abl_a abl_a.bin" and "fastboot flash abl_b abl_b.bin" but the phone rebooted without issue (telling me first I was bl-unlocked)
Click to expand...
Click to collapse
Oh I had to "fastboot flash abl_a abl_a.bin" and "fastboot flash abl_b abl_b.bin" otherwise my software version would be LM-G850N20z (instead of V500N20z)

I successully unlocked my V50 sprint version. It was fairly easy to do it.
1) To be safe, use the original LG cable. was not successful unlocking the bootloader the first time when I used a generic cable. Even though I was able to enter EDL mode.
2) Make sure to verify that the correct abl_a.bin and abl_b.bin versions are downloaded. The size should be about 1MB.
3) One part in the guide that was not clear was which abl engineering image to flash on a and b partitions. Well, it is the downloaded abl_a.bin that should be flashed in the abl_a and abl_b partitions.

I can see this is very recent which gives me hope, I just bought a v50 (v450vm) on a whim and am wanting to flash twrp and install an aftermarket rom on it. Is there a working version of twrp for this model and has anyone had any success in flashing it? I'm really wanting to the try the new unofficial dotOS version that was recently posted. Thanks in advance for any help/info provided.

I finally got around to rooting my Sprint V50 (LM-V450PM), and I agree that the overall process wasn't difficult. It's just that the guide has little to no explanation for specific models, causing a lot of confusion among users in that thread. It also doesn't help that the guide's OP pretty much posted it, edited it once, and never returned to XDA. And the TWRP installation guide posted by someone else is poorly laid out and has been rightfully criticized by others.
So, here are some pointers from my experience:
- Getting into EDL mode is a bit tricky in getting the timing right, so it may take a few tries to get used to it.
- As has already been mentioned, it's a good idea to use the LG OEM cable to connect the phone to the computer. Some people have been getting a "Sahara fail error" in QFIL that might be due to different cables
- You are backing up the abl and boot partition files for both A and B slots because you don't know yet which slot is active on the phone until you enter fastboot mode, which gets enabled after flashing the modified abl engineering file to replace both abl_a and abl_b partitions.
- For getting root, the newer Magisk versions no longer have a separate Manager APK and ZIP files; they are combined into one APK file now. So, instead of the Manager, you just install the single APK file from the Magisk website. From there, you should be able to patch your boot image file just like it says in the guide.
For TWRP:
- As lallolu mentioned in another post, there are two different versions: One for USA models and one for non-U.S. variants. I'm assuming that the U.S. one is for the Sprint and Verizon V50 while the non-U.S. is for all other types.
- You flash the TWRP ZIP package inside Magisk manually as a module. Note that this will remove root as it tells you on the progress screen when done flashing.
- Since for some reason, the touch screen is not active when entering recovery from a reboot, you need to turn off the phone and then enter recovery via the button combination. Some V50 models appear to have the button combination disabled, and there is a separate guide on here for getting it back, but on the Sprint model, it's still enabled: With the phone off, hold volume-up + power, and when the logo shows up, briefly release the power button while still holding volume-up and then hold power again alongside holding volume-up until the factory reset screen shows up. Answer YES twice, and you will eventually enter TWRP.
- TWRP will greet you with a password, but you just hit cancel to continue and get to the main menu. From there, you'll need to go to Wipe and Format Data (where it will ask you to type "yes") to remove encryption.
- Now you want to get root back by flashing Magisk. All you need to do is rename the Magisk APK file extension to ZIP and flash that in TWRP. Right after that, you should also flash a file called Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip which is also needed to remove encryption.
- Reboot into the system, go through the initial setup, and everything should be set.
For the Verizon model, I'm assuming that the "Enable OEM unlock" switch in the Developer Settings doesn't exist, and so the Verizon FRP image used for the Verizon G8 should also be used. The button combination to enter recovery may also be different. But everything else should be identical to the process for the Sprint model.

I finally got around to rooting my Sprint V50 (LM-V450PM), and I agree that the overall process wasn't difficult. It's just that the guide has little to no explanation for specific models, causing a lot of confusion among users in that thread. It also doesn't help that the guide's OP pretty much posted it, edited it once, and never returned to XDA. And the TWRP installation guide posted by someone else is poorly laid out and has been rightfully criticized by others.
So, here are some pointers from my experience:
- Getting into EDL mode is a bit tricky in getting the timing right, so it may take a few tries to get used to it.
- As has already been mentioned, it's a good idea to use the LG OEM cable to connect the phone to the computer. Some people have been getting a "Sahara fail error" in QFIL that might be due to different cables

Did you briefly release the power button and then hold it down again? It may take a few tries to get it right if you are not used to doing this. The white factory reset screen will show up if you did it correctly.

I got into the white factory reset screen by doing the volume down+power. What do i do? Select erase or just exit?

As I mentioned above, you have to answer YES twice. If TWRP is installed, it will go there, and nothing will be erased. If it isn't installed, then the phone will do a factory reset.

Ok. I got into TWRP, but it doesn’t recognize The internal storage. Is there a work around to it?

Fastboot Loop

Hey guys,
I'm currently stuck in a fastboot loop after trying to install Magisk after flashing the Arrow ROM. I believe I messed up when choosing between boot_a and boot_b and flashing the patched img via QFIL. I initally patched boot_a, but when that didn't work I rebooted and patched boot_b. I did this because when I installed Arrow the instructions asked me to select the device slot that was inactive. I thought this meant it was swapping my device slot from A to B, but I probably got that very wrong. I did go into EDL mode and flash my original boot_a and boot_b in hopes it would reverse my mistake, but that did not work.
When I attempt booting the TWRP zip from the lineage guide archive I get this error "failed to load/authenticate boot image". I'm assuming this is because it wants an .img file and not a zip. If I try flashing the same zip file I get this error "Cannot flash this partition in unlocked state".
I did make a backup of all partitions via TWRP before this, but I'm unsure how I'd go about restoring everything. I do have access to EDL mode.
Any help is appreciated. This isn't a primary device though, so if it's bricked I'm not going to be that upset over it. Just something I wanted to try for fun. Haven't rooted a device in years. The G8 was a bit more difficult than I recall, so I'm sure I made a mistake somewhere.
Update 1
I flashed the ABL enginnering file and have some progress. Now fastboot shows my Active A/B Slot. It is set to B now, it was A originally, which I guess confirms that the Arrow OS instructions did switch from A to B. Maybe patching both through Magisk broke the boot image? If I'm understanding this correctly.
Update 2
While in fastboot (Phone was still looping) I entered the following command to change from Active Slot B to A, "fastboot --set-active=a". I've read this could potentially brick your device, but since my device was originally set to A and it was a brick at the moment already I took the risk. Booted into the recovery mode and selected factory reset. It took about five minutes, but I'm now back to the setup screen in the OS. Glad to be back to this point. Now I just need to figure out how to get Magisk Root working without repeating this process.
Update 3
Almost forgot to boot back into EDL, load up QFIL and push the original abl_a and abl_b files back to your phone. Otherwise you won't have any touch input.
Update 4
I seemed to have messed it up again. I tried locking the bootloader back, so I'd stop getting the error message upon bootup. I've decided there is no benefit to unlocking the bootloader and rooting for my purposes. Just wanted to try it out. After doing so I started getting an error stating the device failed security checks, so I pushed the abl engineering file back to the device to unlock it. After I went to push the stock abl_a and b files and decided to go ahead and push the stock boot_a and boot_b to make sure everything was back to normal. Which I didn't think was a big deal, but now I can't boot into the phone without using the abl engineering file.
At the moment I'm unsure what to do. If I push the abl_a and b stock files the phone goes into a fastboot bootloop again. Can't run any commands that way either. I have to boot the abl enginnering file to do so, which in turn allows me to get into the OS but disables touch input. So at the moment I think it's bricked.
If I could find a TWRP image file to flash with the abl enginnering file I could possibly perform a restore from the original backups I made, but I'm unsure where to find one since TWRP doesn't really exist for the G8. I just have a zip file.
Overall not too much of a loss, but the G8 was a great DAP. Hate to lose it. If anyone has any suggestions I'm all ears.

Absolutely the same issue. I wrote about it in arrowOS thread . But I did not try to flash engineering abl. I'm begging you, if your will find solution, please write here about it. I am also notice you here, if resolve this issue.

It's a little confusing to try to determine where you are with this, but I can tell you that for the G8, to get twrp 'injected' into the boot partition, you use magisk and flash the zip, you don't 'boot' it.
So to accomplish that, you need **your specific variant** boot partition with magisk injected into it. You can do that yourself by using the magisk manager, or by simply asking if anyone has that available.
But, you'd then have twrp, and you could flash backups, but, from what you say, it's hard to determine if that's going to help.
If you have one of the variants that has the kdz available, I'd suggest simply use LGUP and flash your kdz, and start from scratch.
Lastly, re locking the bootloader. Numerous people make this mistake, but you can't re-lock it unless you're on pure stock (no modifications at all). If you try to re-lock it and yer not on a freshly flashed stock kdz, you can end with 'edl mode only' device.
cheers

As of right now I have a kdz for my phone, I have a Verizon model. Where I'm having trouble with now is I can't get the phone into Download mode. When I do it says my device failed a routine safety check and then boots to fastboot mode.
I also have a couple patched magisk boot partitions from the initial install. I loaded them via QFIL and I can now get to the Verizon bootup screen, but it gets stuck in a loop.
Update:
I got into Download mode by going into the system recovery and doing a factory reset. Now I need to figure out LG UP.
Last Update (Hopefully) Lol:
I installed the kdz using LGUP and it seems to have worked! I'm back in the stock OS and touch input is working. I'm relieved. I hate leaving things like this in a broken state if it's possible to fix it.
Thank you @AsItLies for responding and helping out!

What I did was put the phone back into EDL mode and open QFIL. I loaded my original magisk patched .img file. This got me out of the Fastboot loop. Then after holding volume down and power to reset the phone out of EDL mode I pressed volume down and power again to boot into the modified system recovery. This took a few attempts as it's really finicky.
Once I was in the modified system recovery I performed a factory reset. This seems to have resolved my "Failed routine security check" error when trying to access Download mode. Now that I was no longer getting that error I booted backup into the modified system recovery and hit power down. Make sure your phone is not plugged into your PC at this time or else it will just boot back up.
Once your phone is off and unplugged, hold volume up and then plug the phone back into the PC. Hold volume up until download mode starts. Now you can go go about installing the kdz of your phone.
Now I'm not sure what model your phone is, but since mine was Verizon I found a Verizon KDZ. Then downloaded LGUP. There are a lot of different variations of LGUP, but for my G8 I needed at least 1.16. So I download the Lab version (Probably not right. It scaled very small, but hey, it worked).
You also need to download the DLL for your phone and place it in your Program FIles (x86)/LG Electronics/LG UP/Model/Common folder. I did have to create the Common folder for some reason, but after I did everything worked fine. Make sure to rename the DLL "lgup_common" (without quotes).
You'll also need the LG Drivers for your phone as well, if you haven't installed them already.
I'll post a couple links for you below of where I got this information or files from. I hope this all helps. If you have any questions just let me know. I'm no expert, but I'll do my best to help.

Woo, thats great, that you resolve your problem! I will try to do all like in your manual.
imei.guru said, that for my imei i have :
Model: LGABCD
Region: ABC
LG LMG820N
With such region i did not find kdz at lg-firmwares.com
When my smartphone boot up (when it was worked) i see LG U+ when booting.
Also it was trying to set korean language. What do you think, which kdz should I take? And what version of android?

also solved my problems - here i described here how https://forum.xda-developers.com/t/...lg-g8-alphaplus-alphalm.4354847/post-86038237
