[justrelax]

i have got G3 (LS-990) Sprint but the software is D855V
the previous owner changed the model from LS-990 to D855V
i have a little knowledge about how to change the model by flashing TOT with LGUP.DLL file

but i cant reverse it to the original Model
i want to change it from D855V to LS-990

Are you absolutely that it is an ls990 and not just the wrong stickers and labels? Open it up and look at the chips inside. If you are sure it is the USA sprint ls990 then try and flash the right firmware with the tot file for ls990. I don't remember all the instructions off the top of my head RN but you can find guides on XDA.

Hi
I had that problem
and I solve it
all you need
LS990ZV4_04.51101.tot Ls990 Stock rom
LGUP_8974.dll mod Dll for Ls990
LGLS990_20140704_LGFLASHv160.dll Original Ls990 Dll
HEx editor
Lg flash Tool (I use v1.8.6.x )
Lg drivers

Steps
1. install Drivers, Lg flash tool, hex editor
2. open LS990ZV4_04.51101.tot on Hex editor
3. search ls990, looks like this
[34 12 78 56 4C 47 4C 53 39 39 30 00 00 00 00 00] 4xVLGLS990
[00 00 00 00 4C 53 39 39 30 5A 56 34 00 00 00 00] LS990ZV4
4. change that 2 lines with this 2 lines (only the part inside "[ ]")
[34 12 78 56 4C 47 2D 44 38 35 35 00 00 00 00 00] 4xVLG-D855
[00 00 00 00 44 38 35 35 31 30 65 00 00 00 00 00] D85510e
5. save it
6. open Lg flash tool, click on manual mode, Use Mod dll and the rom hex mod
7. click on Board DL
8. Use 2.0 USB port and flash it (will be know ls990, but with error)
9. Flash again but using original Dll and original room

It works for me on win7 32 bit
(sorry for sharing hex code like this but xda dont allow me to put links or image )
