So I have a LG G2 D800...well that's what the IMEI sticker says... the phone software detects a d802 international version anyway after rooting it all fine and dandy I go to install a custom recovery I tried twrp and cwm both give out a boot certification verify error, my first thought was that it was bricked but I unplugged it and it rebooted fine. So I have no idea whats going on here and why I can't install a custom recovery.
I just did get this phone back from lg over a bad flash, the flash went so bad that the lg techs said the board was bad and replaced the motherboard.
So any help or ideas why I can't flash twro or cwm to it?

if it is now on kitkat then you need to use autorec; a little concerned about it being d800 showing d802 after being sent back by lg

I'm not sure if it just says that because it's been rooted, but I had to send it into lg because it was either Odin or lg flash recovery that said the dll file was wrong and I couldn't find any way to fix it so I tried recovering it in fastmode and the bootloader some how got screwed.
If I use AutoRec and don't have a custom recovery how easily can it become bricked?
Actually it says whats exactly in your sig, LG G2 D800 on D80020U
And like I mentioned my phone is already rooted so could I just run this root to overwrite it or just go back to stock?

well first if it is d800 it should always say d800 whether it has been rooted or modified(I own a d800 and do lot's of modding always making sure it will say d800 as model number)
yes autorec can brick a device but only if you are using the version which is not for your device and to fix involves a lot of work
to return to complete stock you have use the lg flash tool and tot method

ok then, you should be good to go for using autorec for d800 but after using it you will not be able to use knock on/knock code because it does not have updated kernel for d800 which incorporates knock on/code and I suggest you make a backup and then flash a custom kernel with knock code support for d800 to fix the issue(it happened to me so I should know)

If I do brick it would I still be able to enter download mode and reflash back to stock?
I was planning on flashing Cm11 to it anyway so knock code isn't that important to me, but I do remember being able to flash it then installing Cloudyd3 and knock code would work fine.

Autorec only has a chance of bricking when used for the wrong device, and because it flash a laf.img this means kfbyour device gets bricked by it you lose download mode and have to restore it using adb and fastboot commands
Cloudyg3 includes kernel modification for knock code for d80020u, while on 20k/c this was not an issue

Hello people. I have to ask one question about my LG L5 E610.
My L5 E610 has stock 4.1.2 baseband 20G, most updated to date, I updated via KDZ updater.
I already rooted and installed custom ROM on three differents phones, ZTE and Samsung, never had any problems, so I can say that I have some experiences, but in case of samsung, for use warranty, is needed to install everything stock and reset flash counter, so I wonder if my E610 will be needed the same procedures ?
I'm thinking of installing CM10.2 on my LG L5 E610, I believe one day I will do this, but then I need to know how to install back EVERYTHING STOCK IN CASE OF WARRANTY, but never found tutorial about it, never heard if LG has flash counter, but I bet doesn't have.
anyone can tell me if it's possible or explain me how to install stock ROM, stock Recovery and stock Kernel after customizate everything on E610 ?
Never heard about flash counter.
For returning all to stock (as far as i know) you must have 2 kdz
1: v10d_downgrade , made by someone in 4pda, search it over internet. Its special because it wipes out everything, others kdz just flash up system and that's it, if you already have a bootloop or have a custom rom that may be not compatible with stock, normal kdz wont boot at all.
2: your OFFICIAL stock kdz for your VERSION (e610/e612/e612g/f, etc) get it from here
In case you want to return to stock, boot in download mode (hold vol - / + while connecting usb cable until vibrate) and flash it up. Flash v10d... let it boot (it'll be in russian lol) and then flash your normal kdz (by booting in download mode again)
Then, you can try anything you want (pls, don't mess with swap partition, 2 phones are almost hard-bricked while playing with that and it couldn't flash kdz either!)
Good Luck!
just use the kdz updater

it's thing from Samsung, if users flash the custom rom, the phone will show how much custom ROM was flashed, it can be consulted in warranty that the phone has already flashed and the warranty will be voided. but there does exist methods to do reset flash counter, but I guess only Samsung phones do have it.
but what happens if I have everything custom and then flash the normal KDZ like 20g baseband ? Will be bricked ? and can be unbricked ?
the flash counter can be removed by triangle

I already tried that worked the first time now gets hung up when it runs the LG software up date carp.just says your phone is already up to date
FIxed
I was able to downgrade and fix my issue using the small network http set up in this http://forum.xda-developers.com/showthread.php?t=2625044 thread thx for all the help the other way only works once. After that you MUST "trick" the r&d update tool and lg mobile software to drowngrade to the "newest" firmware version
Folks,
I gave my rooted (mahdi rom) ATT G2 to my teenage son seeing I was no longer using it. He said he tried to update the Mahdi ROM and now it is bricked. From my questioning him all I know is when he was installing the mahdi update, but he did not flash the D800 patch. Noticing there was a problem I think he tried to re-flash recovery or something. All he would get is "fastboot mode".
I think I am a pretty smart guy and have been on XDA for years flashing and what not with no issues - but this one has me stumped. These are the steps I have taken:
1) Finally got it into download mode and when I try to flash the tot file for ATT, it says incorrect model. Says the model is the D801 (t-mobile)! I was like what?
2) So I tried to flash the D801 tot and it seemed to work, but the flash would ultimately "Fail" in the LG Flash Tool. It would boot up into the t-mobile rom but I would get errors and reboots - very unstable. AND the IMEI was wiped!
Does anyone have any ideas what I can try next? I would like to somehow change the model back to the D800 and flash the ATT tot file. Maybe it is truly just bricked!?!?
Any help would appreciated! Thanks!

if you can successfully root device with towelroot(best choice since it is not device specific) then your best bet is to copy d800 build.prop(or to play it safe edit the build.prop model number from LG-D801 to LG-D800) into system/ give it rw-r--r-- pemissions and reboot into download mode, it should say you have d800 and you should be able to flash back to d800 tot(might want to be using d800 dll that ignores model check too just in case)
I just bought a used lg g2. Guy had it unlocked and rooted and used Cyanogen mod for a d801, he used it on metro pcs. He said it was att phone. I verified by disassembling and check the MOBO. The imei also matches a d800. However when trying to return to stock on LG flash tools, I get an error saying device model is different. LG flash tools says its a d801 and im trying to install a d800 file. Anyone have any ideas?
Its running team win recovery v2.7.0.0
and CM 12-20150225 nightly d801
should I flash a d800 rom from recovery and then use lg flash tools?
Have you tried flashing the 801 kdz file? I've seen another thread on here about this specific problem. http://forum.xda-developers.com/lg-g2/help/version-g2-t3042262
No I havent. Just stock d800 tot
Fixed!
Flashed stock as per super sports thread and used the dll file at the bottom of the first post.

Are you sure you have original D802? Because many refurbished D802 are in fact either D800 or D801.
You may need to open it and see main board.
