So.... my S3 kept throwing the dreaded Error S03 and was in an infinite loop. Tivo told me to buy a new unit (really helpful ) so as a last-ditch effort, I found Supafly's virgin S3 image and re-imaged a 750gb drive. Long story short... it worked! However, during I think what was probably the 3rd or 4th plug-unplug of the unit post putting the drive in (I had to put the case back on, blah, blah blah), I left the room during one of the power-up screens and returned to find what appears to be the unit off and the TV black.... but I can hear the hard drive writing away. It has been about two hours now, and it is still in this state. I assume it is updating the software (the virgin image was version 8.0-something). Should I unplug-plug it.... or leave it alone? Just not sure how long it should take.... Any help appreciated.
