Can i use CWM and EXrecovery (v19c) for v20c rom?
Hi @alamatnitotoy !
Me and my friend, who has su880, were testing the v20c kdz.
We flashed v20c kdz using KDZ updater, smartflash and even we tried the offical LG update upgrading from v19c to v20c.
After every way of flasing v20c the phone always stucked at LG boot logo. So We read back every partition from the phone and it turned out that the LNX partition, which contains the kernel, is empty. I mean the kernel was missing after every flash of v20c, but every other partition was okay.
We extracted the the every file from the kdz and the the kernel image was empty in this case as well.
I don't know what is it. Maybe we are doing something wrong or LG simply left out the kernel file from v20c?
Did you flashed v20c?

yes i did flash the v20c. I had that problem before also when using other flasher other than the kdz updater. also sometimes when its failing, what i do is i run the file "Root v20c" thru apx before using the KDZ updater to upload the v20c

Thnak you! The rooting-forv20c.rar contains the v20c kernel file.
I need CWM for v20c.Do you have it?
@alamatnitotoy I looked deeply into why flashing v20c brick your phone. My statement that the kernel image is missing from v20c was wrong. The kernel is there but an wrong place. When you use the extractor from P990 AIO toolkit to extract the image files from AP.bin file, the extractor shows you that which image file is at what OFFSET (or address) in the AP.bin file. Here is what am I talking about:
Code:
[01] address=0x00100000 size=0x00400000 // bct file
[02] address=0x00500000 size=0x00200000 // partition layout
[03] address=0x00700000 size=0x00200000 // bootloader
[04] address=0x00900000 size=0x00600000 // recovery
[05] address=0x00f00000 size=0x2bc00000 // system
[06] address=0x2cb00000 size=0x00600000 // kernel
[07] address=0x2d100000 size=0x12c00000 // internal sd content
These adresses also used during smartflashing. These adresses tells the smartflash where is the kernel image and system image and etc in the v20c AP.bin file
If you flash v20c and you read back the 12th partiton with nvflash you can see only zeros.
If you open teh v20c AP.bin file in a hex editor and you go to the 2CB00000 offset you can see there is nothing just bunch of zeros, the kernel is not there. The kernel actually at 2E000000 offset. Not just the kernel is at a wrong offset, also the sd-img is at the wrong offset. sd-img should be at 2D100000 offset, but in the v20c AP.bin it is at 2E600000 offset. So, when you flash v20c the kernel partition will be filled with 00 hex values and the internal sdcard got damaged as well, because the kernel image gets flashed to the internal sdcard. This cause the Stuck at LG boot logo effect, even if you flash v20c kernel to the righ partition with nvflash, because the internal sdcard is damaged.
Fixing v20c AP.bin file:
There are only 00 hex values From 2CB00000 to 2E000000.
Delete those 00 hex values, then the kernel image and the sd-int.img get to the right offset
Insert the same amount of 00 hex values as the amount of deleted 00 hex values to the end of the v20c AP.bin file to keep the size of the sd-int.img, then save the modifications.
I flashed this modified v20c AP.bin to my p990. I read back every necessary partition with nvflash and everything was okay. bootloader, bct, partitions, kernel, recovery, system are aon the right partition so maybe it's fixed, but I am not 100% sure just 98% because I don't have su880
I want to share you and with others the fixed v20c, so you can test. You can download it here
I want to share my google drive folder as well where you can find my works with su880. It has cwm for v19c and v20c. I also write a read me how can you flash it and root your phone with CWM. Well it was not tested as well, I am 98% sure it works, because rooting p990 and su660 stock roms works that way and p990, su660 and su880 almost the same. I use the CWM recovery image from "CWM for v19c".
My folder is here, some files are still uploading. I will notice you in this post when it is finished
There is no bootloader.img in the folder "SU880_V20C_CWM".Have you forgot it?

Oh sorry . Bootloader is there just rename it to bootloader.img from bootloader.bin, or download the rar file again from my google drive folder. I fixed it now.

You can use this tot file to get your phone back to stock KK:

OK thank you for the file. However call me a n00b, but the file I downloaded was a tot file and the instructions say I should have a kdz file. Should I rename the file to kdz? The tool is looking for a kdz file.

So I had the same issue with my phone. I made a nandroid backup of my lollipop 5.0.1 and installed a MM rom. when I did it didn't work so I re formatted the phone and restored my back up, and I had no imei number, the phone said no service and I had an x at the signal bar. I tried everything, and couldn't get it to work, so after reading different topics, and random side topics, I found a soulution. after I re installed the lollipop version, I found the right modem.zip file for my phone. I used this one http://forum.xda-developers.com/att-lg-g3/development/rom-lg-d850-20f-lollipop-5-0-1-extras-t3052041. download the modem.zip and put it on your sd card. re boot to recovery and flash the zip with TWRP. Than bam, you have your imei and signal back. Hope this helps.
Hy nexus friends,
I need help from someone with a 791F 32GB. I dont know if a 790 or a 16gb version is identical.
It would be great if someone with a rooted device can make a backup for me of the bootloader bin files.
aboot, sbl1, rpm, tz, sdi, sbl1b, tzb, rpmb, abootb, misc, laf, persist.
I flashed the hammerhead bootloader and stuck at 9008 mode.
It will be ver great if someone could help me.
Some partition apps could make a backup or with the dd command.
If i fet a solution, i would post it here. At the moment i had the device and the tools that i flashed for test a nexus 5 sbl. So write is possible.
Thanks for help guys
Where can I see if my phone is 791F?
i have the US Nexus 5X 32GB. Tell me what to do and I'll get you what you need.

Ok. Just rebooted into bootloader and under "Variant" it says LGH791 but no F, sorry
Thx for your help.
You can backup the partitions with some partition backup apps or with dd.
If you look with a file explorer in /dev/block/platform/soc.0/f9824900.sdhci/by-name/XXXXX , XXXX there are the partiton names.
If you want to copy with adb, make adb shell, su, and then:
dd if= /dev/block/platform/soc.0/f9824900.sdhci/by-name/cmnlib of=sdcard/cmnlib.img
Around 36 partitons are in the MM build. System, cache, userdata are not needed..

Have you found a solution to get booting again? Been searching and tried multiple methods to repair my boot image on the H791 I own.
I have worked with another XDAer who extracted and now have the bootimage files from several stock H791 files available. They include the GPT from the stock image MDA89E and the boot image files from bootloader-bullhead-bhz10i.img bootloader-bullhead-bhz10k.img and bootloader-bullhead-bhz10m.img. Let me know if you still need these. I see 11 files in the boot image. During some testing I flashed over the sbl1 on my device and lost the ability do anything but go into QUSB DL mode 9008 as well.
As I am writing this I am now wondering if there is a separate set of SBL etc. files for the International variant? We may need to extract from the 791 tot file available the needed files if we do not have another method of obtaining them. Let me know if you have found a workable way to flash the needed boot images in place. Thanks.

I think the only way from my perspective so far is to manually flash the needed QComm/boot image/boot loader files with something that can interface with the phone. I am pretty sure I know a method to manually do this but need the flash programmer that works with this device to accomplish. Or if there is a way to add MSM8992 support to the BoardDiag tool, that would work...I have not given up, just have not had a whole lot of time to work on this the past 2 days.

I see boardiag for n5 , please don't give up ?.
And i see blank flash file for N6
Try to connect the usb cable with the pressed vol up button. Normaly the lg download screen should pop up.
Its possible then to flash a tot file with the lg up tool.
But i found only one tot file around the i net.
It will be flashed but hang in the bootscreen.
A org. tot or kdz file were great or a solution to create such a file.

Yes. The FW download screen is not an option here. Seems those of us currently needing a solution or method is do to the phone being in QC emergency mode only. I can see my phone in device manager only as with the QC HUSB 9008 drivers.

Today something went wrong while flashing weekly LOS build and my LG G4 (H815 with v20P firmware) went into very fast bootloop: https://www.youtube.com/watch?v=9gm0dh6bLp4
In this state i wasn't able to enter recovery, nor fastboot, nor download mode. Only IMEI screen (Vol Up + Vol Down I believe) was accessible which was no use.
Here are the steps which got me out of troubles:
A) Verify that you have LGUP installed and have proper 8994.dll version for your device.
Different versions of FW use different libraries which results in errors during flashing.
Steps:
1) Install LGUP with this guide https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
2) Get the right DLL. You can try this one:

...or extract it directly from KDZ file with extractor https://forum.xda-developers.com/showthread.php?t=2600575.
You need to extract it from FW version that your phone is already running, not from the one you are about to flash! (when flashing from v20d to v20p you need v20d version, but when reflashing v20p FW you need the v20p DLL)
3) Navigate to LGUP install folder (default "C:\Program Files (x86)\LG Electronics\LGUP")
4) Overwrite the old DLL located in "model\8994" folder version with new one in
I don't know the exact compatibility, or how many different DLL versions are out there. Hopefully it doesn't brick the device even more when wrong version is used, it just doesn't work.
B) Write h815 image to sdcard as mentioned here:

Hi guys,
i came up with a temporary to unbrick LG G4 H815 , you just need a 32 GB SD card ( i used Sandisk 10 class) , the dump that i will link , and Win32 disk Imager, the SD card must low level formatted.
1- download this dump
http://www.4shared.com/rar/NzSqsBzib...230737_00.html
2- put the SD card in the PC and chose the dump file and write ( run as admin ):

It worked for me with just 8GB one. Be aware that the image written to SD have like 20 partitions so windows might go crazy.
C) Follow these steps:

3. One the Write Completes. Eject Card and insert in your LG G4 H811. Press Volume Up Button while connecting the USB Cable.
4. There you go, it will open the download mode.

D) At this moment my G4 finally entered Download mode
I was able to reflash KDZ using the usual procedure (select UPGRADE, find a KDZ file, restart LGUP, select REFURBRISH and START). Initially I got 0x2000 error at approximately 16% (boot displayed as status) that was caused by old version of 8994.dll library.
E) Back to stock
Now you should have stock H815 again so lets flash LOS back as usual
Kudos to OPs: @bullghost , @shakeyabooti , @leptdre , @jam1445 and other posters on G4 section of XDA!
Hope this helps someone!
Good job. If your using this and you're gonna buy a SDCard on purpose, be aware that this fix might not work on your device. Ehehe
@Jirrick im getting the same error on LGUP where do i find a newer version of the dll?

I'm using a 16gb microsd, but however I try to image it (exfat, fat32 filesystems, different win32imager versions) also have tried different cables, but it still doesn't show any sign of life. I bricked it exactly the same way as OP did. Does anyone have anything else I could try to fix this? Also does the battery charge when its on 9008 mode?

Can you get at least to the IMEI Display mode (Vol UP and then quickly Vol DOWN, keep both pressed until it shows up)?

No could it be caused by low battery? I remember it being like 30% when I bricked it, and does it charge under 9008 mode?
Sorry to hear that. I'm afraid this is beyond my knowledge if it wont even enter the IMEI screen. I suppose you can leave it bootlooping in charger over night and then try in the morning?

It does not bootloop, straight up dead. Just shows 9008 forever on the pc, I left it for like 2 hours like that yesterday. I'll leave it overnight today and if not I'll hack up a direct 5v 1a charger to charge the battery directly. If both don't work i'll probably flash LS991 files in QFIL and use it as a tablet afterwards.. damn i got this phone not even 2 weeks ago perfect condition and all. Will not buy any more damn LG devices.
Oh, I thought your phone was rapidly bootlooping like mine did. Sounds like the person who sold it to you was aware that the phone is on last legs (probably even baked the phone so it runs for few days more) and screwed you over. My next phone wont be LG either.
I somehow managed to oem and boot-loader unlock the phone. But im confused on how to proceed from here, I've tried varies methods leading to dead ends and dead links.
I have Qfil and LG-UP up and running with drivers and i know how to enter edl, and fastboot mode.
The closest i think i came to completing the process was getting this error (not support for G710VM21b_04_0812) in LG-UP when trying to cross-flash, for which i have the magisk patched boot a and b, for which i could load into Qfil, but they only work for for this firmware version (G710VM21b_04_0812) which is verzion.
ive been at it for 2 days. So, in short if someone could give me detailed instructions and working download links on any working method to root the phone would be much appreciated.
thx
nevermind i figured it out

LG G7 Thinq
I ended up cross flashing with (G710ULM11g_01_NAO_US_OP_1112) and following this video ---https://www.youtube.com/watch?v=OkdqgNZuQPk---
So for anybody with an LG G7 and boot-loader unlocked here is what i did
Supplies - 1 firmware - (G710ULM11g_01_NAO_US_OP_1112)
2 file - (prog_ufs_firehose_Sdm845_lge.elf)
3 app - Magisk
4 necassry drivers ( i just downloaded anything i could get my hands, not sure how i got it to work)
---i download all these files from multiple forums i could find with active links---
Steps 1. cross flashed with (G710ULM11g_01_NAO_US_OP_1112)
2. Downloaded Magisk to the phone using the phone
3. Boot in EDL mode
4. Open Qfil / set to flat build / storage type ufs *bottom right corner*/ then select this program for programmer path (prog_ufs_firehose_Sdm845_lge.elf)
- Select tools / then partition manager / ok / find boot_a and right click to select manage partition data / then select read data / wait for it to finish and save in edl mode and close it down
5. Find the Qfil folder in Appdata / Roaming / qualcomm *type %appdata% in the Run search if you have trouble finding it* / select whatever Comport folder your phone is in *example "COMPORT 7"* / rename the find called ReadData_ufs etc.............. to "boot_a.img" / Take phone out of edl and restart it normally and plug into cpu / then copy and past that boot_a.img file you just renamed into the download folder of the phone
6. Unplug phone open magisk app / get it up and running / installation method / select the boot_a.img you just copied over to the download folder / check the preserve force encryption box / after finished close app
7. put phone in EDL mode and plug up / Open Qfil / set to flat build / storage type ufs *bottom right corner*/ then select this program for programmer path (prog_ufs_firehose_Sdm845_lge.elf) Select tools / then partition manager / ok / find boot_a and right click to select manage partition data / then select ****LOAD IMAGE**** data / wait for it to finish and save in edl mode and close it down
Notes
1. Unfortunately I'm not a tech savvy person so if anyone has trouble following this please refer to someone smarter
2. I'm not responsible for bricked phones, follow at your own risk.
3. But mine is working and i did all this just so i could have the abilty to change my MAC address so i could use this phone as a media/mp3 device
4. all the forums i used were from google searched XDA's
5. Here are videos i used as references to boot-loader unlock it ---https://www.youtube.com/watch?v=OkdqgNZuQPk---

GOOD LUCK
