Help Sprint LG G3- deep trouble after flashing wrong rom

[jogandrioad]

Hi, fellow forum users. I need your help.
So here is what happen to my phone, I end up flashing the new limited dual 4.0 ( lg g5 based rom for lg g3) and didn’t realize it was for model d855. So basically, I bricked my phone bad by installing a wrong model rom. My model is LS990, where as the rom I accidently flashed was D855. It is essentially in fastboot mode.

Here is what I tried. I can only get my phone into download mode. I used lg flashtool to flash the ls990 tot and original dll file (LGLS990_20140704_LGFLASHv160.dll). However, it didn’t go well as lg flashtool gave me error saying MODEL CHANGED.
Furthermore, then i came across a post where username "iowabowtech" mentions about editing the tot file with hexeditor. So this is the part where I am stuck now. I have to change the tot file LS990 to D855 somehow to trick the lgflashtool into flashing it, please help me on this part. Check the attached image to see if I am doing it right.

Afterward, iowabowtech suggested to use that hexedited modifed tot along with a LGUP_8974.dll (univeral dll for all lg phones).

You only edit the first instance. The one that starts VLGLS. You need to edit out the LS and make that a D followed by 855. Since LS990 has 5 characters and D855 only has four characters, you need to make the zero (0) in LS990 <-- a blank, which should show up as a dot or "period" in that right hand column of the hexeditor.

In other words, you start with..
LS990

And you end up with..
D855.

Ooh sounds familiar. I have a client with a G2 with the same kind of issue but his is a d800 and he flashed some t-mobile rom and the model changed to a d801. He flashed the d801 firmware and now wants to go back to the d800 firmware.
So all things said. Would i edit the d801 tot or the d800 tot? Can i do this on Windows? I do have Linux on a flash drive if not

What jog said. You use the tot for the device he actually owns. Then you edit to the model that he inadvertently flashed. So he'll want to use a D800 tot and hexedit to D801 to allow it to flash back to D800 firmware.

Congrats @jogandrioad on getting your phone back into shape.
