I'm probably gonna get flamed, but here goes. I have a 32 3GS that I jailbroke with Spirit for 3.1.3. I got my new iP4 and wanted to reset the phone with out getting away from 3.1.3 (so I could rejailbreak super easy for sale). I did "Reset all Data and Settings" under the settings menu. From what I understand, this would erase all music, videos, email accounts, texts, ect and also erase everything from the JB, themes, apps, mods, ect. Basically reset it back to 3.1.3 stock, without using iTunes. I was under the impression this would take somewhere between 1 - 2 hrs. But the Apple logo and Progress Bar showed up, the Bar filled up after a minute or two and the phone restarted. It then sat at the Apple logo for over 10 minutes before I noticed. I assumed it was "bricked" and attempted to go into DFU mode. When I would hold down the SLeep and Home buttons the Apple Logo would disappear and phone would turn off, but then immediately attempt to restart without me doing anything. So DFU button combo didn't do anything, I also tried Recovery mode to no avail. Is sitting at the Apple Boot Logo forever supposed to be part of this process? Anything else I can do? I am thinking of letting the batt just die completely and recharging it and hoping that will break the endless reboot so I can DFU or Recovery mode the thing.
