Guide of installing Stock ROM and Kernel after Custom ROM - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

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

my phone has root, free bootloader and with custom ROM and CWM.
KDZ updater won't work on Windows 8.1, installed msxml and put compatibility/administrator and no luck.
is there another way to flash downgrade v10 ?

Scared to flash anymore

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

This morning i decided to flash dori kernel. I downloaded the ota app and through it i flashed the kernel But when it rebooted it got stuck into the dreadful fastboot mode
after that i tried to flash many different kernels through adb but nothing helped and it is still stuck in fastboot mode
After countless hours of searching (still searching) i found that i can fix this by flashing the kdz file in download mode
I absolutely dont want to lose my data as it has some files which are very very important to me
There are various posts which say that i can use normal flash in flash tool if i have the same kdz as before
but i dont know which kdz it had before
it only said d80220b
but when i search for it now there are various d80220b versions(europe,asia,france,taiwan,india)etc

You flashed kernel for wrong variant...make sure you get correct kernel...power off the phone and continue to hold power button until lg screen flashes off again...now its off...hold power +vol down and when lg logo shows release and press both again quickly...a screenfor factory reset will show...follow instructions to where it will try factory reset and it will boot into twrp where you can fix with correct kernel or restore a backup

Thanks for the reply
The kernel was download by the Dorimanx ota app
It says d802 on it though
I can boot into recovery though I dont have twrp i have philz recovery
after that i tried to flash various d802 kernels through adb of philz recovery
but still it stuck at fastboot mode
I was not able to make a backup as the app booted into recovery and installed at once :crying:
Can you provide me a link to the right kernel or the stock d80220b kernel?
That might solve it

Are you on Kitkat or Lollipop? Dori's kernels are for Kitkat ONLY. If you have KK this is the correct kernel for your phone from Dori.

well i was able to fix it (boot into my rom) by flashing the d800 kernel
what does it mean?
does it mean that i have actually a d800 and not a d802?
but it says d802 in the about phone screen and i also checked the imei online it says d802?
So can i now flash the d802 lollipop kdz or the d800 kdz?
does it mean that i have a fake d802?
Yes it is a fake. Open the backcover and read the code..

Someone I helped earlier had the same issue. He reverted to stock using kdz method and his phones said rooted. He was still running stock ROM when he decided to use cse flash. After the flash was complete he booted up and to his amazement all of his files were still there and his root. So what I did was installed the tot and DLL file and restored using the tot method and surel after the flash he wasn't rooted and was on complete stock ROM. Try using the tot method and see if that works.

LG G2 Bootloop, can't get into TWRP

Hi everyone, I perhaps kill my old lg g2 [R.I.P], but maeby you find a solution for that. This is my story.
Today I want to install MIUI 8 so i download one .zip file from this forum. Like always i do full wipe and then install ROM. everything be normal, ROM be installed and i started setting my new OS. After few sec, i can't go thought the setting cuz there be a error. I decided to reinstall system one more time, and this is that moment when I know I f**k up. Off my phone, wanna on TWRP and then i see i can't do anything, phone stuck in LG logo.
Any ida what to do?
Thanks for all ideas.
Maybe go back to a stock ROM and start over? This thread may be helpful in getting back to stock: https://forum.xda-developers.com/showthread.php?t=2432476
The thread helped me go from Cloudy 3.2 to stock MM on a d802.

Right so I'm facing two problems with going back to stock method:
1) as i said, the phone won't boot up on flashing ANY version of d802 firmware (I've observed that in lg flash tool, where you flash tot files, shows that the phone's model number is d802at. So I'll try flashing a d802at fw for the last time and see if it works)
2) i try to flash an ls980 fw, the flash tool gives a model number error. (If flashing d802at fw doesn't work, then i guess i have to modify the hex data in the ls980zve.tot file and force flash it on the phone)
I'll give you an update after something has happened.
@ audit13 it is work!!! Thanks for your help! And I have one last question, I still have root acces and TWRP installed?
Glad it worked
You should be back to stock recovery and no root.
