I need to reset my phone back to factory settings to do a fresh install of a rom, but the conventional methonds are not working (clockwork mod factory reset, i've gone into settings and reset to factory), all ways of trying does not erase the previous data... and on top of things I have a droid x, but on the start up after a factory reset when you set your phone back up it sais that I'm setting up a droid 2 for some reason... i have back ups made of previous roms that were working, but now when i restore to them they are very laggy, and eventually freeze the phone up... will flashing the SBF file help to recover the phone, and make it think it's a droid x again??
