Develop Bugs

Please help me understand my options. I bricked my Zenfone 2

I'm seriously stressed from thrawling through forums making posts and as of yet I've got no answers, hopefully someone here can help me or discuss my problems.
Yesterday I tried rooting the ZF2 Z00A , Originally a CN 2.20.40.63. It went into bootloop.
At this point ADB does not recognize the phone but fastboot does.
I tried installing a non rooted rom via SD Card but I got a signature verification error.
Now it looks like my only option is to flash a pre-rooted rom via Fastboot as that still recognizes the device. However I cannot find a CN 2.20.40.63 or newer pre rooted rom, I can only find CN 2.20.40.61 ....... am I right in believing that this would not work due to .61 being older than .63? Would it matter if I flashed a WW rom that was .63 or later? Even if it meant the phone was buggy but then allowed me to unroot and install a stock rom I wouldn't mind, I just would like my phone to work again (I only rooted because there was random webpages and apps opening and downloading the whole time).
Please somebody help. Also my brother who is in another country has a rooted CN 2.20.40.63 phone, is there anything he can do?

Invalid Software Package & Rooting questions

Hello XDA,
I got an LG G4 gifted, and as one of the first things I want to do is to root it. However I seem to have quite some difficulties with it.
My previous phone was a Nexus 4, and I simply rooted with 'Nexus Root Toolkit'.
For this phone there appears to be many, different ways to do that.
First thing I need to be sure is what exact model my G4 is.
In 'Phone Info > Hardware' it simply says H815. In the LG Mobile Support Tool it says H815B (Which gives no result on Google). The phone is from Germany if it helps.
Second thing is that it says I can update to SW version v10c. But when I download the update, it simply throws a 'Invalid Software Package' error at the end of it. The LG Mobile Support Tool says I have no update avalaible instead.
Third thing is that I don't remember if I have to unlock the bootloader to root my phone (did that only once on my N4, forgot if it's needed). If yes, can somebody link me to the appropriate page? (I've read around LG itself released a tool to unlock that?) (Also, I will loose all my data IIRC?)
Last thing, obviously, the most appropriate Root guide for my model. I've read many of them, one requires you to have linux on your PC (Which is a nope), others mentions '10c' (which I suppose is the update I'm unable to get). So far I got myself only very confused. (Root voids warranty? IIRC LG still covers phone with root?)
Thanks in advanced for your help
EDIT: Currently trying with LG Bridge software, seems to work and says my phone is H81520A (So I suppose the part after the device code is the 'SW Version' ?).
EDIT2: Apparently updating with that software worked. Now on v10c (Marshmallow 6.0 - Unless there are other updates waiting)

You can indentify your model by adding your IMEI to the following link: csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=
(look for the field buyer)
The unlock process is described in this thread.
But don't fash SuperSu If you are on Android 6.0, because it will fail to boot. First flash an custom kernel (like this) and then SuperSu.
If you're unable to unlock the bootloader, then there is no possibilty to get root on Android 6.0.

Thanks. It says DEU at the buyer line.
D(eutschland)EU(Europe) I suppose.
And thanks for the link. In the kernel page it says 'download 20a or 20b? What's that number? So I need a Kernel that inclused SuperSU as flashing it on its own will cause that problem in few words?
What about this? http://forum.xda-developers.com/g4/development/repack-kernel-root-android-6-0-t3232387
From what it seems, it's a custom kernel + root. Would I still need to unlock the bootloader? Perhaps using the 'LG Site' section from the thread you linked (http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241)?

The software versions are quite strange on lg phones. 20A was the first test version that was released in poland. The official version now is 20B but phones with a branding have different versions. For example my phone has a vodafone branding and has the version 20A, but it is the same as unbranded 20B. (so it's really strange some times)
Look what is written in the settings under software information.
You need to unlock your bootloader to root your phone on Android 6.0 (this will void your warranty). You're right, it seems that SuperSu is already integrated in the kernel so you don't have flash SuperSu separately. But i am not complete sure because i didn't unlock my bootloader.

Thanks a lot for your help.
I managed to unlock the bootloader, but then I fuffed up..
Accidentally installed SuperSU (Was following that guide, and forgot about what you said).
Now the phone is kinda stuck at the very start, with the LG Logo (Not the animated one, the very first one)...
I'm hopeless now? D:
EDIT
I'm trying to recover with this video (LG G4 KDZ Firmware Restore Unbrick and unroot tutorial -- can't post links yet..)
But the LGFlashTool throws an error at 9% (imgur link -- can't post them fully yet) imgurDOTcom/pR1NYHD
EDIT2
Apparently I'm trying to flash a KDZ with Android 5.x while I'm on 6.0, which is a no. Will try with a 6.0 KDZ if I find one...
Else I hope for LG assistance (Or Amazon support, since the phone is less than 1 week old)
EDIT3
No luck with KDZ, but now the phone is going past to the animated logo, but being stuck there..
EDIT4
This saved me: http://forum.xda-developers.com/showpost.php?p=63843511&postcount=146
Worked perfectly, my phone is back and fully working

Sorry, i wasn't online the last couple of hours, but i'm glad that all worked out for you

No problem, you were of great help.
I'm currently not trying to root until there is a safe procedure to do so for 6.0

I don't think that there will be an easier option in the near future. You can make a backup with twrp and try to flash the kernel again.

Mmm, currently I have only the bootloader unlocked. No root, no custom recovery.
I don't feel like to play more with these stuff in the near future, after I nearly bricked the G4
Perhaps later on.

Downgrade MM to LP from sd CARD, NO more bricks :D video

On 551 Z00A or AD the official downgrade version of LP WW-52.20.40.196 firmware from any M stock firmware - via sd card
https://www.youtube.com/watch?v=_1T6SMJiUSg&feature=youtu.be
Success -- Downgrade of MM to LP works with the downgrade firmware above , works via update from sd in MM recovery ------- Marvelous
Stays on` updating IFWI ` for approx 8 mins but after that - bingo !
It also erases data after which it didnt updating in same OS
Also , i set it up -- after a reboot , it detected .134 and ..144 and .184 MM update packages and now also should detect .223 latest firmware if on ext SD if written like mentioned and shown in the video !
The above LP downgrade version is detected in .223 latest M firmware after a reboot.

Some pics

Seeing a lot of people bricking their devices downgrading to LP from M .
There is now no need for all these bricks when we can downgrade via M recovery to LP via ext sd card .
If you are on a stock rom MM bl and rooted TWRP ..you just need to flash stock boot.img and recovery for the MM build you are on . Reboot to stock M recovery. Follow above procedure.
If you are on M bl custom Rom and rooted TWRP but have no stock M back-up , flash back boot.img and recovery for.134 , sideload .134 stock. Then downgrade
That above applies to 551 Z00A .

Merry Xmas to all at XDA --Still seeing people looking to downgrade from M to LP even after posting this method above via ext SD card - WOW
So , my present to you is a video of the above process
Say NO to anymore bricks Say NO to ever having to use xFSTK downloader again
This makes our phones fully , changeable forwards and backwards via SD card (for good)
The process will go from .184 M to .196 LP on the 551 Z00AD or Z00A
If you Have MM bl custom rom - use giovix`s Modder tool to `return to stock option` flash boot.img - flash recovery option in Modder . Follow process.
Video Coming Soon ...........
Ps, i assume the process will be exactly the same for Z008 from the latest Stock M to LP but using the relevant downgrade version(whatever that is) from official ASUS site for Z008
I dont have a Z008 so if anyone wishes to attempt it and give me your results here , that would be great for others
pps, i decided to do the video due to either people dont trust this method or people are extremely shy about hitting the thanks button . Whichever -- help others

Yup, using the Asus files to downgrade from MM to LP bricked my brother's phone. I've tried a few methods with xFSTK to fix it but nothing has worked so far. Looks like the phone will be recycled Oh well, he seems pretty happy with his Samsung Note 3 for now

You need to have a working device to downgrade via SD :good:

Okay, I was able to restore stock MM to the phone which is what it has before it bricked. Problem now is that I can't verify the Google account I tried both of my google accounts without success. I'll have to find some other method.

But you was bricked a moment ago - no comprehendi ?:laugh:
If you used xFSTK you wouldnt need to downgrade , you would be in LP already.
If done on another device try later , maybe a reboot :good:

I was bricked and was able to iFSTK to get into the bootloader. I then used the Asus Flash tool to flash an MM raw file to at least get the phone booted. I was happy until I was stuck at the set up screen with no way to verify the google account.

Now its time to party vid coming soon .
All the very best wishes to each and all

MM raw file Hey , please share here ?
If there even is a MM raw file that is
Flash 5.0 raw for 5.0 then you wont need to downgrade btw
And this is nothing to do with downgrading via SD card btw - off topic

I believe I used the MM ww raw file from here: http://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256

Hi , I understand where you went wrong , you flash raw again in boot loader ,where it stays on ' RESULT=OK ' a couple of mins into flash in on screen cmds , you close flash tools . Force close it...restart flash tools .put all stuff in again ...then press vol+ once.
Leave connected to PC from first part flash all the way through closing flash tools and restarting flash ..do not touch fone apart from vol + before second flash.
Serial will be corrected and you will boot into system.
There is a vid of this exact process in my unbrick thread.
Enjoy
Ps , I never let the first flash finish , due to knowing above process to correct serial..
So if you run into probs , you may need to re flash in xfstk again.

THANK YOU, THANK YOU, THANK YOU! It worked.
This is what I did to cause the loss of serial #:
used the sd card method to downgrade from MM based on instructions from another forum (i.e. not XDA);
phone got stuck at the erasing portion of the process and stayed there for about 45 minutes so I powered off the phone;
used xFSTK to successfully flash the bootloader
successfully flashed MM raw file with Asus Flash Tool;
tried to downgrade to LP again and bricked again;
used SFSTK again but serial # was now abcde... in bootloader so I used Asus Flash Tool again. AFT never finished flashing a ROMand the phone was stuck on the bootloader screen with "Result: okay" so I just shut down the phone and left it off until I saw your post this morning.
Edit:
I set up the phone ran software update option from settings but the Android Version is 5.0? Also, when I boot into fastboot, I see the serial # as abcde... but I can get the proper serial # by pressing the volume up and down keys a few times. Lastly, my SD card is not seen in recovery but is seen in the ROM. When I boot to recovery from the bootloader, I see this:
Android system recovery <3e>
LRX21V.WW-ASUS_Z00A-2.20.40.198_20160930_8756_user
E:file path/tmp/last_install

E:file path /tmp
Finding update package
Opening update package
E: file path:/sdcard/MOFD_SDUPDATE.ZIP
E: failed to map file
SD installation aborted.
E: Installation failed with status 1
I'm not too worried as these things are cosmetic. The important thing is the phone now works

Just to clear things up.
You never bricked your device using the method in the OP regarding downgrading via sd card. So not to scare people off .
Mofd sdupdate method is for adb sideload using a cable.
In the video it shows how files must be written when downloaded for each stock firmware in file manager in the first few mins. To be recognised from ext sd
Lastly , 2.20 in firmware or raw = LP
4.21 = M which doesn't have a raw yet unless I missed it coming about

[Asus Zenfone 3 Deluxe ZS570KL Pro] Android Oreo update's problems

Hello,
I don't receive any more OTA updates on my Zenfone 3 Deluxe ZS570KL Pro (Z016D) whereas before it was able to download them and to install them.
I contacted the support of Asus compared to this problem. The support, after investigation, indicated to me that it had undergone a modification either by the use of the official tool UnlockTool or by the installation of a bad version of firmware. However, I indicated to them that this telephone was new and no modification had undergone. It managed to receive OTA updates.
As it cannot any more download and install OTA updates, it was advised to me to carry out the updates manually.
I carried out manual updates WW-5.15.44.2588 and WW-5.17.44.68 with success. However, when I wish to carry out update WW-15.0210.1804.47, this one fails and doesn't install.
Could you indicate a procedure to me to install this update and to explain me the reasons for which it doesn't install ?
Moreover, there is it a method to lock the bootloader again on this phone if it was modified as the support of ASUS indicates it?
Anyone else has this problem and found a solution ?
Thanks a lot.

you have to lock your bootloader again then try to flash the official firmware from asus website. flash it thru stock recovery on apply update bla bla

Had the same problem, used ASUS Flash Tool. Info on this Forum, you will have to reflash TWRP if you use it.

LG G8 (LM-G820QM) Unlocked

I have LG G8 Alexa variant. Model LM-G820QM.
I think ts on latest firmware "qm21e". Right now I live in India so the VoLTE is not working. I tried to cross-flash it to Open firmware but LGUP gave error "Cant change the device(AMZ_US > OPEN_US)".
I have three questions.
Can I cross flash Korean firmware ?
And if so, will i get VoLTE working ?
And my G8 has 2 cams while the Korean varient has 3 cams. Will my cams work with Korean firmware ?
Thank you.

Do you by any chance still have the OPEN_US Firmware?
I've been looking everywhere for it but I can't find it.

I think any of this 2 are OPEN. If not then reply me back I will deep search on google. I happend to found it somewhere but can't remember where exactly.

Thanks for your reply
Unfortunately, neither one worked.
I tried the first one, however the flash tool didn't work because (OPEN_US_>NAO_US)
The second one would not download at all. I don't think it would have worked anyway since my phone is not the Alexa version. It's factory unlocked, purchased from Best Buy.

Hey man, I was able to figure out my problem! Not only that, I discovered one of the NAO_US Firmwares was actually OPEN_US, and that worked for my phone. I am now back up and running, with an unlocked bootloader and Root!
I appreciate your help, and I want to help you if I can.
As for the cross-flashing, you can't do it via LGUP. The only possible way is to download the firehose for your phone and to use the Qualcomm Image Flash Loader(QIFL) tool. You can extract the firmware you want to flash, and load all the images into the QIFL partition manager. There is no guarantee your phone will boot from it, but you can try it. NOTE: Do NOT modify the OP partitions! This will cause your phone to throw an OPID mismatch error and it won't boot!
As for the cameras, you may be able to extract the current Camera APK from your phone and install that on the Korean firmware so that you are still able to use them. No guarantee this will work, and they might work fine with the Korean camera APK, but it's worth doing before you flash.

I see, but I just want VoLTE to work. I don't mind using stock rom or custom rom too. So keeping that in mind what do you suggest? And also, Do you think that your solution " I discovered one of the NAO_US Firmwares was actually OPEN_US, and that worked for my phone. I am now back up and running, with an unlocked bootloader and Root! " could work for me too ? If so do let me know how did you figured that NAO_US was actually OPEN_US. Maybe I can find out one for AMZ_US.
On the box Model : G820QM
SKU : G820QM8 (QM8 stands for AMZ)
Thank you.

I'm really not sure how VoLTE works internally, so I couldn't tell you if using another firmware would actually work for you - but the way I found out one of the firmwares was actually OPEN_US was by extracting it using the KMZ extractor tool someone made. This is how I was able to reflash the partition on my phone that I screwed up on in the first place and created a brick with. Like I said, you could manually reflash all those partitions one-by-one in QFIL, but i don't recommend it as it may not even work and could potentially brick your device. It's really up to you in this case, if you'd like to try though:
Download the firmware you want to try, search for KZM extractor on Google, download QFIL and all of it's prerequisites, and finally the firehose.
Use the KZM extractor and place the firmware inside of it.
Once it is done extracting all the files, put your phone into download mode and open QFIL
NOTE: DO NOT FLASH THE PARTITIONS WITH 'OP' IN THEM! Your phone won't boot for sure!
From QFIL use the firehose file and manually, one by one, sort through the output files of the KZM extractor and find the partitions that match their name and flash them with the file.
Zero guarantees this will work, and you may end up with a brick for a phone at the end of the day, but if you're that desperate it just might work.

Hi there.
I am still looking for solutions for VoLTE to work. I googled a lot and came on this post " https://piunikaweb.com/2021/06/07/unlocked-lg-g8-thinq-now-supports-att-volte-after-april-update/ "
Mine is Amazon version "QM8". Yet I did received april update via OTA. But still no VoLTE. I can OEM unlock from devs. Can I flash AT&T "QM7" on Amazon "QM8" ?
What do you think of this please let me know.
Thank you

VoLTE seems to depend on files in the OP partition, so crossflashing other partitions but not OP will not get VoLTE to work. LGUP will not allow crossflashing.
See my experience to get working VoLTE and Wifi Calling: https://forum.xda-developers.com/t/lg-g8-volte-fix.4113291/post-85455109
You will need to be bootloader unlocked and rooted.
