Hi all
I have done my best to search all the possible solution on xda as well as google, and I don't think I found the answer.
Basically, my phone (for some unknown reason) now suddenly have the boot loop issue.
I first tried to use the LG PC suite, but it is never able to find the phone when it is connected in download mode.
I then tried to use the LG Flash Tool v.1.18 to flash a stock rom in download mode, but failed, due to the following error (of course USB driver is installed, and COM41 changed)
Code:
PID: Null
IMEI: Null
Model :
DLL: D855
BIN: LGD855AT-00-V10g-222-99-JUL-14-2014-16G+0.TOT
SWV:
SWOV:
Model Information Check Fail
000000000
Finally I use LG Flash Tool 2014 to flash a stock KDZ image, using CS_emerengcy and CES flash, the KDZ image is obtained from the LG dev using my own IMEI. This method actually works, but after it reboots, and goes into the Android Setup wizard, it restarts itself and stuck in boot loop again!
So what may I do please? I am very stuck and have no clue.

Did u try booting into recovery and doing a factory data reset after flashng?
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 drivers…
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

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?

Yes is the only mode i cant enter, download mode (pressing vol +) and got to upload firmware screen. I connect to flash tool and up to 6% and crash.
I try factory reset (power + vol -) it says ok but nothing happends... now if i power normal, lg logo starts, says boot verification fails, and the screen goes black.
>I connect to flash tool and up to 6% and crash.

Not a brick. You must change the dll in lg up
By replacing existing LGUP_8994.dll . search xda ...cant't post link
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.
