I have an old iPhone 2G (first generation) that I plan on using basically as an iPod touch (not using the phone portion). I no longer have the AT&T service on that phone. I installed an update to the firmware (stupidly) this morning because iTunes prompted me too... and now the phone seems to basically be bricked. Upon completing the firmware update I was stuck at the "connect to iTunes/emergency" screen.
For the past 10 hours, I have tried to restore, I have booted into DFU mode. I have even resorted to attempted jailbreaks, all to no avail. No matter what I do, I still get that "connect to iTunes/emergency" screen, and while the "iPhone" displays under Devices in iTunes, the iTunes page simply says "iPhone". There is no Summary Page, no iPhone section, no version section, no backup section, etc.
I installed iTunes 10.5 and I am pretty sure the firmware for the 2G phone is 1.1.3 (although I had attempted to roll it back).
Does anyone have any ideas on why this is happening and what can be done to get this iPhone back up and running?
