Help with Official Flashing on LG G2 - G2 Q&A, Help & Troubleshooting

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

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

[Q] Fixed my D800 after being bricked but now I am stuck with Jelly Bean? Pls Advise

Hey guys,
I have been for hrs trying to find a way to update to Kit Kat to no avail.
I was on Kit Kat on my D800 but decided to try CloudyG3 rom to get a feel for the G3 interface etc.. but, I didn't like a few things and wanted to revert back to my stock Kit kat since I have a backup.
I was able to use the TOT method with LG Flash tool etc.. but the only stock firmware I was able to successfully install is D80010o. I have searched and found a thread explaining how to install Kit Kat, but the link to download the version is not working and the mirror takes you to the jelly bean ones.
I can't update it via the phone as an OTA update either. I need to get back to Kit kat so that the backup I made will accept the restore of my old settings.
How can I go back to stock kit kat, please help me find a way. I will greatly appreciate it.
thanks
Why can't you update it via an OTA update?
root, autorec and install a rooted stock rom

When I check it tells me there are no updates available for my phone that I am up to date at 4.2.2
maybe it is because I messed with flashing the baseband? It says I have version ending 1.0.190034
Are these the files you downloaded?...
LGD800AT-01-V10o-310-410-OCT-19-2013.zip
LGD800_20130904_LGFLASHv160.dll
... then used LGFlashTools v1.8 to flash the *.tot per the instructions in the second part of the OP in this thread:

that's exactly right.. although when they send you to the link to download the TOT file there are 2 tot files. One is the one you showed here and the other is V10d with a date of August. They do not specify which to install. I did it with the V10d. then trying to fix it with the V10o but the flash tool would not install it and gave me an fail load error. so I kept it at V10d. Now I am stuck with jelly bean apparently?

hey man.
I tried it and the LG mobile tool said that My device has the latest software available from LG Mobile support Tool. and a pop up window says "no upgrade items to fix"
Gotta tell you though that today I had a message on my phone saying I had an update available and when it booted to the android logo to start the process it said that my phone was rooted and that I can't get the update (because of that)
So I probably need a way to just unroot my phone and get back to completely stock as If I was starting from zero.. Is there a simple way to unroot?
Try this:

Edit: After 20c is flashed and says it is up to date, just contact AT&T and ask them to manually push the 20u update to your phone. That is what I had to do.

Dude, try looking for methods on how to do a hard-reset on your device. That would be the first thing you should be looking for.
Sent from my LG-E425g using XDA Free mobile app
I deeply searched into google / XDA and Turkey forums and found an information : You can not install any kind of stock rom which is different than original onto 311K models.
Finally I found a way that is work
I tried TOT method but does not work (different model error) and then I decide to try a different way that never tried before
* I have V20C Turkey Stock rom. (laggy and buggy )
* Rooted and installed TWRP
* Download CloudyFlex custom rom. Opened the zip file and deleted all things under "system"
* I extracted Germany 20H KDZ file (system.img) and copied all things into system folder into CouldyFlex zip file.
* Now I have cloudyflex.zip which includes system folder from V20H (Germany Open firmware 16GB)
* Installed zip file from TWRP. Now my device's LG D802. (was D802TR)
* I use the TOT method and installed V10A firmware (tellcon)
* Then I tried Lg Flash Tool 2014 way - finally it is OK. Now I have stock rom V20H Germany Open.
I had the same issue after flashing Cloudyg2 3.1. When I tried to go back to stock flash tool stopped at %2 and no flashing was possible. Thanks God I had TWRP. My solution was to flash the flashable zip stock rom I downloaded from the below link. After installation I was able to use KDZ method again with no error.

hi
This is a g2 thread. You might wanna post it on g3 thread instead.

Pre-rooted .tot / .kdz file ?

HI all !
Today I was on reddit (https://www.reddit.com/r/Android/comments/4ek7ue/lg_v10_has_root_now/) , and I was asking myself if it was possible to repack .kdz / .tot file ? I know root method already exist for the G2 and every variants, but I think it's more easy for someone who wants to go back to stock to use a preroot stock file rather than re-root every time using actual method.
I already managed to decompress the .kdz file with this tool thanks to @bullghost . I download UpTestEX.exe , but now when I try to merge all files, I have thoses errors : http://imgur.com/a/LU7SH .
Thanks !

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.
