Well, now I am convinced that something glitched during the 3.0 update. I posted earlier that I could get back into the recovery menu, but that was it. Well, first thing this morning I tried a power on again, black screen. I proceeded to the recovery menu and chose "restart system"...............and it booted up to version 3.0!!! I played around in the menus for a little bit, I did not try a game or movie, but, thinking it was fixed did a soft power off. It did not boot back up. I tried a brand new HDD, no change. I tried all the restore menu options again, no luck. Finally, I decided to just keep soft powering it on and off, probably 20 times, and bam, back to the standard boot! I am in the process of doing a full system restore. We will see what happens. I figure that if this doesn't work, maybe when the next firmware update comes out, if I can get it to boot again, I can update the firmware and it will re-flash the ROM and fix it.
So again, I think that something glitched during the firmware install and it did not write to the ROM correctly. I don't think its 3.0 that is the issue, but the install itself like several have pointed out here. I will post back when I have news.
