Hello. My LG G3 D855 originally ran CyanogenMod13 Nightly, and for some reason 6.0 Marshmallow GApps did not work. So I attempted to flash back to stock using LG Flash Tool. However after the flashing (successful), my phone would only boot into Download Mode, even after hard factory reset. Nothing worked, ADB, fastboot, nothing. So I then downloaded the older version of Flash Tool (2014), and the G3 D855 6.0 marshmallow KDZ. I believe this was successful, as now the phone changed from download mode to the MiniOS boot animation. However that is all it did, just displayed the animation. I attempted a hard factory reset (and the design of the screen had changed, which is why I assumed the KDZ flashing worked). That didn't help, and so I booted back into Download Mode, and tried flashing the TOT file for my device using the newer Flash Tool. However the new Flash Tool didn't even recognize my device, and so I, in one last hopeful effort, downloaded LG PC Suite to try and fix my phone, but in Download Mode or otherwise, my phone wasn't detected. I've tried flashing other versions of the KDZ on my phone, all unsuccessful. And of course there is no recovery I can access. Please any help would be extremely appreciated.

Hi,
I tried to upgrade my LG G4 H815P with this thread:
https://forum.xda-developers.com/g4/development/h815-nougat-stock-locked-bootloader-t3709119
The process with LGUP was ok (upgrade mode), but after the first reboot the phone stucks on LG logo, so I tried to use refurbish mode but the process throws a error 0x2000.
I tried a lot of solutions but the problem continues.
Maybe you know a tot file with android 6 to restore my phone with LGUP?

Seems like the restore only works with H81520p_00_0314.kdz
Solved!
Hey guys
First, a little bit of history:
I own a G6 now, so I wanted to have some fun with my G3.
I rooted it (LGOneClickRoot), installed TWRP, installed LineageOS 14.1 and everything went pretty well.
The problem was that LineageOS 14.1 is terrible, huge lags, tons of bugs, so I tried installing another ROM through TWRP, I don't know what I messed up but I messed up and the flash failed. I dont remember exactly what I tried to flash after that but I failed again and then classic --> Stucked on LG boot logo, no recovery mode, no download mode, nothing.
So I used the popular fix for hardbricked G3, creating a short between test point and ground while connecting it to revive him, and it worked. I went with the whole procedure in BoardDialg and stuff. Kinda surprised by myself that I didnt go full-panic mode creating tons of threads everywhere lol, I managed to make it work even if it took me something like half a day of learning and work.
Now I'm back to stock Android 4.4.2, rooted with LGOneClickRoot again and everything is fine.
I mean... Almost everything is fine, because now I want to be able to install Magisk, and I found that Magisk is for Android 5+.
So there are some informations I need to gather before going further and risk a brick again (please no more short on the motherboard lol):
1- Can I flash a stock Lollipop ROM with LG Flash Tool in download mode using CSE Flash ? Is it a proper way to do it or do I really need to go through this boring TWRP recovery flashing again ?
2- where can I find such a ROM (stock Lollipop for d855) ? And which version to chose ? v20a, v20e, v20f, v20h, v20i, v20p, v20t, v20u, v20w or v21a ? I've been looking for hours now, hard to find reliable informations about all different versions.
Thanks for the read, I hope someone can help me
UPDATE:
I flashed a Lollipop v20f with LG Flash Tool and it's working fine.
I heard that after v20f, newer versions were "harder" to root so I sticked with v20f.
I'm gonna play around with Magisk now and see how it goes.
I'm in the same boat. I also went back to 4.4.2 via TOT. The I rooted and installed TWRP. how I want to restorel my RR 5.8.5 from a TWRP backup. My question is to I have to install the 35B bootstack before or after the restore or at all?
Hi,
Upgrade (LGFlashtool + CSE flash) to V30B
Follow this post ==>
https://forum.xda-developers.com/lg-g3/general/root-twrp-marshmallow-d855-30b-t3286268
Then you can install custom Rom ou upgrade to stock V30N (with root : there is a post about it)
Hey how did you do the unbrick process? I stuck at flashing kdz eventhough i have correct dll and drivers installed
hi,
Try LGUP instead of LGFlashtool (download mode and type *.kdz + select kdz file in LGUP)
Depends if you're hardbricked or softbricked. I was hardbricked so I had to create a bridge between 2 points on the motherboard and reflash everything one by one. I formated recently and didnt keep all these things but I can get into it again to try to help you.
EDIT: LGFlashTool isn't enough if you're hardbricked, you'll have to use other tools and open your phone. First step is identify if you're softbricked or hardbricked, google it you'll find your answer
Mine was hardbricked. I use shorting test point method and successfully flashing partition. Then I flash kdz using LG flash tool 2014, my phone stuck on boot logo. Then I do factory reset. Still same. Last option, I use LG UP. It stuck on LAF info with number on it. Is my LAF file damaged?
Hi,
With Boarddiag try this :
1-EMMC TEST Option "erase" ;
2- then Restore theses partitions and reboot in download mode and flash Kdz.
1)Boot
2)Aboot
3)BackupGpt
4)Boot
5)dbi
6)laf
7)PrimaryGpt
8)Recovery
9)rpm
10)tz
11)sbl1
