After 2 day
My problem have been resolved (by me)in this morning:fingers-crossed:
Soo good morning every body
I have got my g2 backed
I will tell u if your problem just like me
To force flash firmware without checking model numbers on your g2
1.do not use kdz file (but we still need it)
2.do not use up testEX
MAIN program we need is Lg flash tool
Just download your right kdz firmware file
Download your right tot firmware file
For model dll do not use dll given with tot file
Just use kdz extractor and extract your dll from your kdz file
Flash it with your tot firmware in lg flash tool
And Good luck:laugh:

I am in the same problem you had and I have read your solution but I do not understand how to extract the kdz.

[q]Force Device to Install Rom From Other Model

Hi, I accidentally bricked my phone by installing F302S rom into my d802 (CloudyG2 3.0)
After lot of struggles I managed to fix the download mode (it's booting on fastboot previously)
but error occured when I flash d802 stock kdz file to my phone, it stopped at 49%
in the download mode it displayed my phone as F302S instead of d802
and seems like the error is because the flash tool does not allows me to install d802 as it is not F302S
I've read about cross dll file / LGUP_8974.dll for this problem, but I can't manage to understand it, can anyone please guide me on this?
any help will be appreciated greatly

Please help me anyone,
I'm getting desperate on this
I've tried to extract the kdz for my d802, and manual flash using Flash Tool V1.8.1.1023 with LGUP8974.dll from F320 and the extracted dz file of my kdz
but the flashtool does not detect my phone at port COM41, I've installed the driver too
please anyone, thanks

Have you tried Returning to Stock via the .TOT method? Refer to this tutorial.
The .TOT and .DLL file for the D803 including extracted 10C partition images (if ever needed) can be found here.
A lot of people who get stuck at 2% for the KDZ method are able to successfully Return to Stock using the .TOT method.

I'd also recommend using the .tot instead of .kdz... I'm on the VS980 (different variant I know), but I've never had luck using the KDZ method and always have to use the TOT method. Pretty much the same with a different file.

the .TOT method seems like it would work BUT when flashing should begin in the flash tool, it tells me the phone model is different , I'm thinking I need a .TOT for D803R20F ( the .TOT file in your link says LGD803 V10c ), that is how the KDZ file wich I've succesfully used in the past was named , any ideea where I could get that file ?

[Alternate solution] Lg g2 vs980 recogniced as model L01F

Yesterday I installed this rom:
http://forum.xda-developers.com/lg-g2/development/lollipop-grola-rom-5-0-1-t3028569
And after it "finished" the phone got stuck in a fastboot screen, and the usb was not working, neither the recovery nor the bootloader.
So I really screwed it up, the I followed a tutorial in youtube to fix corrupted qhsubs , It was awfully hard to make my device to work, so now that I'm finally capable of entering into the bootloader when I use the lg flash tool with kdz, it gets stuck at 2%.
If i try to flash via tot+dll it shows that my lg model is the L01F.
I have read about doing a cross dll editing with a hex editor, but I have tried and I dont get to work neither the dll nor the tot file
***************************************************************************************************************************************
The posible solutions
There are many posts out there to edit with hex editor, in order to trick your phone to install the rom, also there are posts that will indicate you ro reflash all the .img again by killing the bootloader and entering in fastboot mode, but at least for me none of this worked.
The solution that worked out for me (thanks to Ayala's Inc youtube channel)
What you will need:
1-Lg flash tool for TOT files
2-Generic DLL
http://www.mediafire.com/download/vh6y1unm9fq8vtx/LGUP_8974.zip (893kb zip)
3-.tot image file that you are going to flash
http://storagecow.eu/index.php?dir=Xda%2FLG+G2%2FStock%2F
Note, if you are in this post, then you will realize that the .dll that are in the link above are not working for you, you must instead use the generic dll that it's in the zip.
How to flash, now this part is know by almost everyone:
1-Open flash tool.
2-Check the "select manual mode" box.
3-Load the generic .dll in the DLL part.
4-Load your image .TOT in the s/w part.
5-Do not modify anything else here.
6-Connect your device in download mode
7-Go to device manager
8-Scroll down below to Ports (COM and LPT)
9-Right clic to your device and select properties (Lg mobile usb serial port)
10-Clic in the port config. tab, then click in advaced options
11-Set the COM port numer to 41 and accept.
12-Now back again in the flash tool Click in the yellow arrow that is in the top left, and wait, if it doesn't start the process automaticaly, disconect your LG (keeping the download mode) and reconect it to the pc.
13-Wait for the process to finish, after the proccess is over, you will be able to flash any stock rom, your LG g2 will no longer be confused about its model.
*If the kdz lg flash tool stucks at 2%, this will be your solution.
*If the TOT lg flash tool doesn't flash because the rom/dll/phone is diferent this will help you to solve the problem
This might work with all the variants, I haven't tested, but it should because it's the generic dll file.
There it is the video, that helped me out, credits for him, he told me about the .dll solution
I can't visualize the video correctly so here is the link:
