Restoring LG Optimus 2X P990 back to stock LG software I have flashed a lot of custom ROMs onto my phone, like CM7, kangs and such of CM9 before it's released, MIUI, and so on. I didn't want to wait till the third quarter of 2012 before I got some IC on my phone. Now that we're almost that far into 2012, I was wondering how I could restore my phone back to LG's stock Gingerbread software - the one that i had before I flashed CM7 - and unroot my phone.

I have lost my backup so I cant restore. I'll have to use smart or NVFlash or something like that. How can I restore my LG Optimus 2X P990 back to original LG software, so that I am ready for updating it to LG's ICS release?
There is a zip file that is posted in this video description that you can flash via Clockworkmod or your favorite custom recovery that will revert your device completely to stock (including removing the recovery image and such).

The video goes through the process step-by-step, for your convenience, but it's basically flashing that file via CWM, and then being happy :)

It also goes through how to unroot, if needed!
