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.

If you can go to S/W download mode then flash this with smartflash. If you can't go to S/W download mode use "Bootloader installer for v19c", and flash that rom I linked

The bootloader installer is at the first post of this thread.
Enter your phone to APX mode:
Remove battery
Press and hold volume_up and voulume_down button while you connect USB cable
Install APX drivers
Run the bootloader installer for v19c.
Hey i need bootloader for v20c.Can you give it to me?
Hi I'm a noob who just bricked my F240L (korean ver.):crying: I somehow wiped my system partition and the result is disastrous; KDZ flashing is impossible via R&D / support tool and I can't even get into the recovery mode. Only download mode is available.
I heard that it could be fixed by using NPST but I only can find the files for E980 at
http://forum.xda-developers.com/showthread.php?t=2272177, not 240x series. Moreover, KDZ files for OG Pro cannot be extracted by using LGExtractor so there is no way I can get this file by my own.
So is there any possible way for me to get those files??
-------------------------------------------------------------------------------------------------------SOLVED----------------------------------------------------------------------------------------------------------------------
How to solve it ? I'm also having the same problem
I got the same problem also, mine is F240L (Korean version)
The differences is I can manage to enter CWM, but the CWM can't mount external SDcard. As if my MicroSD doesn't exist.
I got no backup file to restore via CWM 6.0.3.3.
Using R&D Tool to flash, after 10s update process. Appear error message "Insufficient Battery Level to Proceed", that's strange because the battery is 100% full.
Using KDZ Updater, the error message appear "File Extracted Error" for 2 KDZ files I got (10T and 10V).
Hard Reset didn't solve the problem.
Now I'm stuck in DOWNLOAD MODE and CWM 6.0.3.3 (can't do anything in CWM).
Before entering CWM, there's an error message "Secure Booting Error ! Cause : Device Unlock, so Boot success !"
Please, anyone would be so kindfull to HELP.
@stupididiotism can you explain how you solve it ?
@chimmot307 have you ever tried this version to flash (translate from chinese)
so my phone was bricked (only download mode available) 1hour ago:
go in download mode->install LG support tool->in menu go to "customer support"->"recovery phone"->(your imei should be here or enter it if not)->click check
and now wait it download the whole img and flash it for you
The firmware 10T in baidu.com is broken, asking for username and password to resume. Little HELP with the username and password, fellas ?
I follow your advice go to "customer support"->"recovery phone"
After 10s update process. Appear error message "Insufficient Battery Level to Proceed", that's strange because the battery is 100% full same with 2nd battery whose 100% full also.
It seems LG Corps. tried to block anyone outside Korean to update their phone (I live in Indonesia, got this phone from real Korean people who sale this phone in Indonesia illegally, because Indonesian market is E988-16GB storage compare to F240L more spacious).

Following your 1st advice, I managed to download the KDZ from baidu.com, and run the tutorial step by step. Everything runs smoothly.
Thanks in advance @smaybe. I owe you BIG one.
:good:
For those who got stuck in DOWNLOAD mode, you can follow these steps (in attachment).
LG PC Suite won't recognise my device (in DOWNLOAD MODE), it only recognise when in LG SOFTWARE MODE (Settings => PC Connection => USB Connection Type => LG Software).
So I can't go to Device => Firmware Recovery.
Why did you delete the 1st advice, @smaybe ? Totally recommended.
hi guys
I was in the worst condition : wiped system partition and moreover, I hard reset my 'rooted' phone.
Recovery mode not supported and kdz flashing also not working.
Then I found this divine tool called 'LG mobile flash tool v1.5' and I could find the tot and dll files for F240 series from some china website (I paid for that tho)
So my point is if anyone holding F240L and having the same problem as me. Then I can send you the files. I feel like posting the file here is a violation of intellectual property of the chinese devleoper(?! what am I saying?)

LG PC Suite sucks
I've updated to the latest version, it still doesn't recognise my F240L (in SOFTWARE MODE), it said "Need to change with the right cable" even when I swap with different USB cable.
Or maybe my Windows 7 Ultimate (64bit) having problem in compatibility with PC Suite that won't recognise the USB. Cause, I haven't try with different operating system (Mac, or Windows XP)
Stuck in U+ LTE Logo
Dungeon Hunter 4 messing my Optimus G Pro in this thread http://forum.xda-developers.com/showthread.php?t=2380374
So I decided, to wipe system & data partition.
Hope that KDZ Updater will bring it back normal the way smaybe told me to.
KDZ Updater show 100% Finished, but my F240L still stuck in U+ LTE Logo.
So I try new LG Mobile Support Tool, Upgrade Recovery => IMEI=> OK. Updating to 1.69 GB, 100% finished, still stuck in U+ LTE Logo.
I haven't try LG Mobile Flash Tool 1.5, maybe stupididiotism could tell me step by step ! And not to forget to send the TOT & DLL files.

I run LG Flashtool according to website http://forum.gsmhosting.com/vbb/f177/lg-flash-tool-free-no-need-b2b-user-pass-1628819/index2.html
Extract F240L10t_00.kdz from Baidu.com, got 2 file :

- F240L10t_00.dz
So I used those 2 file in LG Flashtool ( I don't know if those the correct files to use in LG Flashtool, cause I can't seem to find DLL file for F240L, but I think for S/W file is correct ).
Used port COM41 to flash (DOWNLOAD MODE is activated on F240L). Then I unplugged the USB cable for 5s, and replugged it. Error message appears as follow.
Am I using the correct DLL file to flash ? If not, would you be so kind to upload the DLL so I can flash my F240L ?
Thanks.

Hello I read all threads with brick text, i try all and i cant to unbrick my phone.
I try to update my lg g3 but i block the bootloader or something, then i enter in fasboot and i delete recover and follow this tutorial
http://forum.xda-developers.com/android/general/unbrick-lg-model-download-recovery-t3060184
With this i sure make a mistake, i upload all from 30b version, and in the tutorial dont say i need to flash custom1 and custom2, so i didnt... then i get out from fastboot and now i enter in download mode. I use flash tool 2014 and flash tool for tot files, with 2014 not work, with tot file it starts (i try with 10a and 10e version) but try to delete custom partition and fails in 6% says this
[17: 7:55] Can not find Parition name : cust
and not work any more.
I think the problem is that is expected 30b with custom partition and is not there, so it not continue. Any ideas what can i do?

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?

VS986 Stuck on Download Mode

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.

I just did all your steps for my VS986 , and I got 2 G4 Verizon's back up and working , Thank you so much.
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 will be simple, after installing this room
https://forum.xda-developers.com/g4/development/h815-nougat-stock-t3659860
, I had a problem, ie I had more access to the recovery mode, then I wanted to install marshmallow but the phone remains blocked on
firmware update do not unplug the usb connection until the process is complete...
even when I remove the battery and then I turn on the phone it remains locked
Screen:
http://zupimages.net/viewer.php?id=17/37/z8va.jpg
i think you didn't install any Nougat bootloader and modem before flashing the rom
In TWRP wipe everything, then flash Nougat Bootloader and modem (this file) from TWRP:
https://www.androidfilehost.com/?fid=745425885120759121
and only after install Freedom Rom:
https://www.androidfilehost.com/?fid=745425885120759485
Check if it works

lg g4
thank you for having answered, the problem I have no access to the TWRP, when I want to access the TWRP it makes a return to:
firmware update do not unplug the usb connection until the process is complete
thus impossible to install this link:
H815_29a_Modem_and_Bootloader_no_splash
Ok try with LgUP
1) First install Lg Bridge (for LG usb driver) HERE
2) Then install LG UP HERE (both LGUP_Install_Ver_1_14_3.msi and then LGUP_8994_DLL_Ver_0_0_3_23.msi)
3) After download THIS and copy these 2 .dll here C:\Program Files (x86)\LG Electronics\LGUP\model\8994
Download a .kdz LG G4 firmware like this 20d HERE
4) GO in Download mode with your G4
Plug the USB Cable into the PC(not connected to the LG G4)
Have you PC Powered On and Logged in
Power Down the LG G4
Press and Hold the Volume Up Button on the LG G4
While Holding Volume Up, Plug the USB Cable into the LG G4
Continue Holding the Volume Up Button After You See ‘Download Mode’
Let Go of the Volume Up Button When You See the ‘Firmware Update’ Screen on the G4

5) and following the indication you need from this post
TO DO A FULL WIPE AND INSTALL MM
1) Open the LGUP on your computer.
2) FILE PATH point it towards the MM KDZ (LgUP will see only .tot, so when you browse and search your .kdz pay attention to change in the menu .tot to *.* to see everyfile you have)
3) After you load the .kdz now shut down LGUP!
4) Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section.
5) Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient

I have the exact same issue, tried the above but lgup wil stuck at 11 procent with an 0x2000 error message "Invalid command response"
I have tried to flash the 20d version a couple of times but no luck with that so I tried the 10b version still no luck and ending up with the same error. So I decided to give it another try with H81520p_00_0314.kdz and guess what, it flashed and booted up and installing apps now.
I have not been able to download the file, every time I have this error message that appears:
Download interrupted
