Last night, I flashed a friend's Xbox 360 (had a BenQ drive) with iXtreme 1.6 and now, after he's taken it back home, it has the RROD!
I booted up a few backups of mine to test it last night and they loaded up fine. Granted, I didn't play them at all - only loaded them to test the Xbox was accepting backed-up disks.
Not really sure what to do now! Has the flashing caused this problem or was the problem there before and it's a coincidence that the console is RRODing now? Help, please :(
