Yes, if you scroll down apear a lots of No then you find a yes in CWR and do factory reset.What version of CWR do you have installed :touch or non touch?

ok im sorry!
Did not noticed that i can scroll down -.-
did a facotry reset but device is only loading recovery( CWM v6.0.2.8)
may i can flash a firmware by using adb or try to make a hard reset?
or can i flash the normal bootloader from this point?
if already a thread exists im really sorry, but i searched a long time via google.de and xda but i did not find a working solution for me.
i even tried to flash the firmware on over pcs but i always get errors and come back to recovery or emergency

Try to flash a rom from cwr.For exemple i use this rom.Download via pc ,remove sd card from phone, copy rom on sd card ,then insert sd card in phone.Boot in recovery ,after that install rom:

i have tried to use the cm10 rom but after restarting only the recovery is loading -.-
does anyone else have a hint for me??
Yours Sincerely Jan
EDIT: does anybody have a working link to a stock v20a firmware ? I only geht errors that i do not have access

SOLVED
My LG is back in LIFE!
Think the reason for it was that i flashed the normal stock v20a and not the v20d or so but I`m not quite sure..
Thank u for your HELP!

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

[HELP NEEDED] LG G2 D802 won't boot and in download mode it says model is F380K

Hi everyone,
I am having issues with this phone of mine. Here is a background of it:
My phone is rooted and is running rayglobe rom. I tried updating the update that it gave me and made me stuck in bootloop.
Now I downloaded another rom, which I don't remember since this happened december 2013. after flashing, it does not boot and does not make me go to TWRP anymore. Now I tried using download mode to restore my phone. but eveytime I try to flash (using the 2 methods I saw in the thread), either it hangs at 49% or the other one does not start flashing because it says I have inconsistent dll? I downloaded a D802 stock rom and tried flashing via download mode and it says that I have different model (F380K). Now I tried downloading a dll and F380K stock rom, but won't allow me because it says that my phone is D802. But when I go to download mode it is korean and it says F380K.
I think I have flashed a korean rom before which made this incident happen, but do you have any idea how I can restore this?
Thank you all in advance.

If this was me, I would do a factory reset.

sounds like you should go back to stock firmware.

First check what exactly phone model in Internet Browser. Then download TOT and flash back to stock.

I faced similar problem with D800. I had the correct dll and the firmware but it failed saying my phone model was different (I think its because I tried the "upgrade recovery" option on the LG PC software by selecting a different model).
My phone was passing the LG screen and stuck at android boot screen.
What I did:
Pushed a kitkat based rom for D800 to sdcard using adb on Linux (on windows adb failed to recognise the device).
Then adb reboot recovery and flashed the rom.
Then I was able to flash the factory image.

[Help]Motherboard problem lg g2 d802

recently, I rooted my phone and after that I updated via software-updater and it rebooted. finally , it had an error ''boot certification invalid'' and after that I install twrp on my device and tried to backup everything(also efs) and it went right. I have a backup but after that I wipe everything (also efs) and i wanted to try to install d802 stock rom via zip files on the forum and all wipe is ok and i went to reboot recovery after that my phone's motherboard has a debug. Guarantee service said me : '' there is problem motherboard software and we can't repair it. You should change motherboard '' .
What is your advice for the problem? Do I need to go to another guarantee service ?
Sorry, my bad english....

it seems your motherboard's hardware is fine since you're able to do all the things you mentioned and the phone boots to recovery, I think it's a firmware issue.
I would try to force the phone in download mode and flash a stock .kdz file through the Lg firmware utility.
you should find all files and instructions on the xda forums.

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..
