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.

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.

[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 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] No recovery after flashing stock rom? LG G2 D802

Hey guys, I've been having some issues booting into recovery since flashing the stock rom back onto my LG G2 D802.
My phone had been rooted and was using TWRP as it's recovery tool. However, I wanted to unroot and go back to stock on this phone so found a guide in order to do so.
I followed the guide exactly as it is in this thread and completed 100% but now when trying to go into recovery mode nothing happens, the screen just goes black and just reboots itself.
Does anyone know if and how I can get the stock recovery back onto my phone?
Thank you in advance

Well you should clearly use a descriptive title as I got into this thread without any expectations.
Anyhow, depending on the rom you tried to restore, you might have ended up with LP modem (from cloudy 3.1) on a kitkat rom... or not, considering you didn't really provide much information and I have no idea what variant are you talking about.

Help with Official Flashing on LG G2

Hello Guys,
I was wondering if you can help me out clarifing a few things about flashing roms in .kdz format.
So i was on Cloudy 2.2 and had a lot of issues and then i decided to revert to stock. I followed the hyelton thread and did the TOT method. Now i have the phone on 4.2.2 working fine. At this moment i want to upgrade to 4.4.2 or 5.0 but when i check for updates i get the information that i'm on the latest SO. So my questions are:
1. How can i force update to 4.2.2 or even 5.0 without rooting? I tried to find the TOT file of a lolipop rom to flash via tool but can't find any.
2. I tryed to flash a .kdz lolipop rom via LG Tool (i extracted the dll and DZ) but i get an previousLoad error... so any suggestions?
3. The last case i could go back on rooting and put a custom recovery and then put the lolipop, but to achieve this, from 4.2.2 wich steps should i follow?
I'm asking this here because i saw multiple threads and discussions but can't get the right ways to do what i want.
Thank you very much.
Cheers
Note: The version is d802, portugal.
Well guys, after much nerves and errors.. here are my conclusions
1. If you want to use Lg Flash tool and flash a stock rom with .kdz extension, you need to put the rom file in the tool folder then run the tool with admin prev. Then select the file and press cse flash. You'll get an error on connecting to servers probably (i got one). Ignore it, but DON'T click on nothing.. the process is still runing, so even with error, just wait... you'll see your phone doing some progress. After a while it will reboot and VOILA
2. About TOT file, i just went with the kdz method.
3. To get the right KDZ file use thiss repo: http://devtester.ro/projects/lg-firmwares/
then you can put your imei and get the rom or just find a rom that fits you.
4. To get the lattest Lg Tool go here: http://lgflashtool.com/
Notes:
. Keep in mind that the .kdz files are big (>1,6gb) so make sure the download is not interupted, use a download manager or firefox. If its corrupted you'll have problems.
. All the files and sites are not mine, i'm just mentioning them.
Now running stock lolipop with no prob.
Cheers
