You must go with your Tablet into the download mode and make a restore with the LG Mobile Tool on your Windows PC ,
You have a guide in a post by the section android development !

I don't know where to start. So I changed the resolution of my LG G3 F400L to 1080p via terminal. then I reboot it. The LG boot logo appear, after waiting for a while the logo won't go anywhere. the boot sound can be heard also when I touch the screen I can hear unlocking sound and touch feedback which means my device is working properly JUST the LG bootlogo covers up everything just like a curtain.
Another thing is, I tried to boot it to recovery to restore my firmware but it just won't work. My device has TWRP flashed by AutoRec. I used every button combination and tried like 100 times each that I found here: http://forum.xda-developers.com/lg-g3/help/f400l-recovery-t2960352 but the device won't boot to recovery. It just boots normally and stuck on LG bootlogo as I mentioned above.
Running to a dead end. I put my device to download mode (which the only mode that I'm able to do) to flash my device back to stock ROM using LG Flash Tool. After a few processes it stucks at S\W Upgrade part saying "Upgrade stopped due to an error". Just so you know I have the latest driver installed.
The stress and frustration really makes me want to bump my head to death. Any help and solution IS GREATLY APPRECIATED!
Please Help me.
yesterday after answering a call my LG G3 suddenly rebooted and since then it keeps rebooting after the "LG powered by Android" screen. I cant even go to recovery. I've searched and tried everything so far without success. My last attempt was restoring the phone using LG Flash tool 1.8.1.1023 (phone in download mode, TOT, DLL, COM41, etc) and everything gone OK, program reports "success at 559s" but it keeps rebooting on the same screen. any idea how to fix or the phone is dead? I was using LineageOS 20170515, TWRP 2.8.7 bumped/mod, pico GApps. It is the 32GB/3GB RAM unlocked model
flash D85530B_Global using flashtool2014 on download mode and see goodluck,if it doesn't fix it try changing the battery don't buy it just try one if it works then buy it
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
So, I have the LG G4 AS986 which I presume is very similar to the Verizon VS986 but I decided to post here because they aren't exactly the same model. The phone has been working for years but recently got the dreaded bootlooping issue. I decided to follow a few guides to try and fix it by using LG KDZ Tool and LG UP and bricked it. I was able to unbrick the device by flashing some G4 Sprint files using the Qualcomm tool (qfil?). After unbricking the phone, I put the phone into download mode and flashed the phone using LG UP with a KDZ from the Verizon variant. LG UP said it was successful, however, whenever I try to boot the phone, a message pops up with "Secure booting error: 1006" or something similar to that and stays there until the battery is pulled. Somehow, I was able to flash TWRP on the device by nuking the laf partition but even flashing a custom rom on the device using TWRP, it still encounters the secure booting error issue and won't boot. Any help will be greatly appreciated! Thanks!
