firmware update do not....lg g4 h815 - G4 Q&A, Help & Troubleshooting

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:

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:

and only after install Freedom Rom:

Check if it works

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

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.

LG G4 H815 stuck, download mode only, no adb

Hello hello,
I unlocked bootloader, installed TWRP 2.8.7.0 (adb -> fastboot method) and then I flashed SuperSU 2.46 zip. After reboot from TWRP my phone stuck.
I can't access TWRP or i don't know how to…
System isn't starting BUT sometimes after few minutes of seeing LG logo i see standard wallpaper and suddenly animation freezes. That's all.
When i go to recovery mode (voldown+power, release power and press power again) I can "do" factory reset. I choose 2xYES and i see green android. Then phone is restarting but i should enter to TWRP, right?
I tried to flash stock system (kdz, tot, dz) via:
- LG Flash Tool 2014
- LG Flash Tool 1.8.6.527
- LGUP
- LG Bridge
but nothing…
My phone PID and IMEI is null :/ (and "CUMSS" to :?)
I tried fix that with QPST (2 different versions) but in device manager my phone is only detected as COM port. No "Android Device". I can't read and write anything…
adb isn't working
I tried all USB 2.0 ports, different drivers, roms (even not for 815), dlls.
I fought 3 days and still have brick, not smartphone
I have only download mode working.
I can send commands to com port (Send_Command.exe) but sometimes nothing happen, sometimes i see "fail" after sent command.
Any ideas? Can I install recovery through download mode? Or maybe somebody know how to send files to phone in download mode but without adb?
I had stock rom MM V20L. What else you need to know?
Thanks for any suggestions, sorry for chaos in post and my english.

After trying different roms in different programs with 3 versions of dlls and different driversâ€¦
I found solution: just reinstalled .NET Framework and then finally i flashed by LGUP (refurbish, v20L, kdz, dll 0.0.3.23)!
Welcome back H815

[Unbrick] How to revive H815 - no recovery/fastboot/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.
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

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.

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.
Click to expand...
Click to collapse
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

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.

Flash failed, stuck in download mode (H815)

Hi guys,
for the last months I was using LineageOs, but since they dropped development for our device I wanted to get rid of it.
I tried to get AOSP running but failed. Next I flashed a stock kdz file in Download Mode using LGUP and it worked,
I was back to stock. I tried to install AOSP through TWRP but failed again and eventually ended up doing a hard reset.
This temporarily bricked the device because now the stock android booted and Android Device Protection (FRP) was
active and didn't let me log in. Desperate to find a solution I flashed random kdz/tot files for the device that I found on
the Internet until one finally worked (LGH815 EU Nougat 7.0 BySezerSimsek), the FRP thing was gone. Then I tried to at
least get back to stock again, but when I tried to flash the stock kdz file LGUP aborts at 25% with Error Code 0x2000.
Every time I start the phone now, it goes directly in this firmware update/download mode.
The device shows up as "LGE AndroidNet USB Serial Port" In Windows Device Manager
In Download mode it says "633A B92 Official" on the display
I already tried:
Different dll files for LGUP
Using LG Flash Tool 2014 instead
Putting dump file on SD card
Should I put it in 9008 mode and work with QFIL or what am I supposed to do now?
Thank you.

I'm still able to get into fastboot mode btw. But I'm going to wait for replies here
before I make things worse. If that's even possible at this point. :silly:

My phone is alive again, thanks Jason:laugh:
Just a short recap what I've done now in case it helps someone with the same problem, the full instructions
are in Jasons link.
I used the KDZ and TOT Extractor to extract the LGUP8994.dll file out of a stock Marshmallow v20p KDZ.
I renamed the dll to LGUP_8994.dll and moved it to C:\..\LG Electronics\LGUP\model\8994, overriding the
existing file. Now LGUP was able to flash the v20p KDZ without the 0x2000 Error.

LG G4 H818N Stuck in Download Mode

Hi, I've been trying to fix my H818N from the past couple of days.
Here is what I did to brick it, unfortunately
1. Downloaded Nougat 7.0 TOT file (H818P v29a TOT) from this website: androidsage lg g4 android 7 0 nougat firmware
2. Started my G4 into download mode and tried to load this TOT file using LG UP, however, LG UP stopped me by displaying an error message: Invalid TOT file
3. Then I used WinHex to change H818P to H818N in the TOT file and saved it
4. Now I was able to upload this file to my G4 in Refurbished mode using LG UP, the upload completed, phone rebooted and displayed: Erasing
5. After that it is stuck in download mode (If I restart it, it displays LG logo and starts download mode automatically)
6. In Download mode, my phone displays this at the bottom of screen:
U 633A s12. 0 AS10. 5 B100 UHS
S U LG-H818N 07.0 Hrev_10 .CPU4
H81529a
Here is what I did till now without any success:
1. installed the latest LG drivers, LG UP, and LG Flash tools on my PC
2. Tried to Flash the following firmwares using LG UP/ LG Flash Tool (I also extracted the dll file from each firmware one by one and placed in the model folder for LG UP while trying)
H815 V20o Modded.kdz
H818N10l_00_0113.kdz
H818N20f_00_0818.kdz
H818N20h_00_1019.kdz
H81520p_00_0403.kdz
H81820p_00_0314.kdz
Hong Kong H818N10b.kdz
H81520p_00_0314.kdz
H815TR20g_00_0428.kdz
F500K20C_00.kdz
All the firmwares get stuck at Internal command failed 9%, 11%, 24%
3) I have scoured the internet but wasn't able to find a solution yet
4) I even tried using the fastboot mode but unfortunately the bootloader is locked and I cannot erase the recovery or image
Now I'm not sure what else can be done to bring my phone back to life. I might try to get it into Qualcomm 9008 mode and try to unbrick it by following this guide: pakfones unbrick lg g4 hard bricked
Any help on this will be much appreciated
