Guide of installing Stock ROM and Kernel after Custom ROM

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 ?

[Q] LG G2 D802 Kitkat root problem

Hello,
I have LG G2 D802 brought from UAE. I accidentally upgraded to KitKat 4.2.2 after I brick my phone when trying to install trwp recovery in my 4.2.2 firmware. As I was eager to root it, I saw a method using IOroot25. It went very well and speruser and busybox are installed. But the recovery was horrible as it is not recognising my internal memory at all, when I tried to flash zip files it is not showing in the sd card and no option for back up also. So I tried to use the trwp manger, after that now when I tried to boot into recovery, only error message comes saying that " certificate error", Otherwise the phone is working very well. I tried to unroot using the flash tools, failed, also tried to downgrade firmwae to 4.2.2. using flash tools, failed. No neww rooting method also appering in any of the LG g2 forum. Kindly anybody can help me to solve this problem.
Thanking You

Downgrade worked for me twice. Just after downgrade, you must perform a factory reset.

I tried downgrade using the Xda thread. When I start upgrade, it goes to LG site and says you have the latest firmware, and it stops there. Can you please send me the details how you downgraded. Remember my 4.4.2 shows it is rooted, I tried to unroot using this thread thttp://lionking853.blogspot.ae/2013/10/how-to-root-and-unroot-lg-g2-all.html.

No unroot will work. Only flash back to stock which was as replied above. Do not use the official lg tool. Use the one in the thread above.

Help w/possible bricked G2!

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)

[Q] [Urgent] g2 stuck in fastboot mode after flashing dori kernel .Which kdz to flash

Hi everybody
i am a newbie here and require serious help
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
now i want to know if i can flash any d80220b (europe,asia etc) in normal mode over my previous one without losing any data
I have 32 gb d802

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

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..
