can't unroot T mobile LG g2 kitkat
1) pre-OTA update to Kitkat, using the guide that said back up to D80110c.kdz
2) loaded d80120a.kdz
5) tried to revert to stock Rom using UpTextEx.exe - but where it normal ask for English/Korea imput, I get a screen with the following:
Port, ESN/IMEI, Model, etc. But all my phone info is missing.
Click read phone information and it starts to scan then I get a popup: Port (USB or Serial) not found. I click okay (only option) and it keeps scanning but as of now, it doesn't add info at all.
I don't want to start the upgrade (as it's not an upgrade) for fear of deleting the IMEI or some other item that will turn my phone into a permanent paper weigh.
Just need to get this back to scratch so I can sell it.
So does anyone know how I can restore this to original settings if UpTextEx doesn't see my info?
