Help please. Lg g3 f400l bricked - G3 Q&A, Help & Troubleshooting

Hello worthy developers. I am facing an issue with lg g3 f400L just bought. It was on kitkat so i tried to root it but it stuck in boot loop. Then i downloaded the tot 10a to flash stock via tot. But it failed. I found 30c marshmallow kdz and tried it too but it restarted at 60 percent. I didnt find lolipop kdz on google tried alot. Its second time i am facing this already paid once in market. So plz help me guyz. What are my options.. I should add one more thing that i flashed same tot on another f400 L modal that was working. But not in my case

Instelled new kdz, or use tot and dll, downgrade 4.4.2, update lollipop, root and recovery, and installed bumped F400L for recovery.

root (stump) , re-root (IOROOT), BUMP, TRWP,
Rooted with STUMP initially just fine. Then had to factory reset due to a malfunctioning app.
Stump does not (yet) support re-root after reset unless you flash back to stock. http://forum.xda-developers.com/lg-g3/orig-development/root-stump-root-lg-g3-sprint-verizon-t2850906
Thanks for all the helpful posts in several threads. I Rooted using IOROOT, using ADB no problem. http://forum.xda-developers.com/showthread.php?t=2776198
Now running BUMP TRWP recovery too. http://forum.xda-developers.com/ver...pment/bump-unlock-lg-g3-twrp-verizon-t2900590
BUT, since i'm somewhat of a n00b, i used Flashify from the Google Play store to flash the image. Worked flawlessly. http://www.droidforums.net/threads/...ock-and-install-recovery-on-any-lg-g3.275056/
(in flashify, pick 'choose file' and navigate to the .IMG file)
Thanks!!

My phone does NOT work so I'm not sure why the change log states 12B.
What was upgraded, fixed, etc from 10B to 12B? Not really a fan of downgrading.

No there isnt unless you downgrade to KitKat
But it seems i cant find any KitKat firmwares for the F400L online
f400
In as much as the g3 is a GREAT "looking" fone with "some" great aspects.
after going thru the issues i have met with my korean version, LG has created A DISASTER
there are more than 12 dif. versions none is even close to the other.
the korean versions are ORPHANS they have download and recovery entries issues no developers
ONLY the d855 seems to have a bit of a base.
my advise look for a kitkat KDZ file or TOT and load them via download root it with towel root and don't ever think about
doing anything else.
this is my first and last ever LG fone.
even the ONE+ has better developers than this crap.
google f400k 10a or 10e files and load them, root with towel root and be happy
the kdz 10a or 10e are available in some vietnamese boards
supposedly they have the 20e and 20h versions and after loading these under recovery
if you go back also under recovery and load a preset superuser 2.39 you're supposed to be able to root it
it never worked for me, once i set the lollipop, i have no way of getting into recovery mode and if i do both
under TWRP to fone craps
i personally am waiting for the ONE+ TWO and will give this one away, it's a LEMON.
good luck

D852g Cant revert to stock

Good morning
Im using a Canadian version of the LG G3 D852g on Videotron network.
I have been able to root and twrp the phone no problem. I have tried most of the roms available (candy cm 12 etc)
I installed cloudy 2.5 for my model of phone and since then i have been unable to revert to the stock OS via the KDZ method or TOT.
What is odd is that the KDZ worked no problem until after i installed cloudy 2.5
The KDZ method would now stall at 2% and indicate that it can not find my device. (yes i know drivers com port 41 etc etc etc)
I downloaded tot file and dll required for my device and when i run the LG flash tool.
SO then i tried the TOT method to revert to kit kat. and this is where i got a weird error message

Any help would be greatly appreciated

Downgrade problem

Hello!
I am running 20A (Poland Beta) because I am not able to downgrade to Lollipop. I don't know what happend but if I try to downgrade using LGUP (the same way as 2 months ago) it stucks at 13% and error 0X2000.
Can anybody help me ? I only want my specific system ACZELD.
I tried:
Phone in Android, LGUP refubrish/upgrade
Phone in Download Mode, LGUP refubrish/upgrade
what KDZ are you using?
I already downgraded my system. I downloaded the SAME kdz 3 times. For the last time, downgrade was successfull, but I don't know why, because on my friend's G4 also first two downloaded KDZs was OK
