I have a 3gs - old bootrom. I was happily rolling along jailbroken and unlocked, running TMobile, in iOS 5.0.1 using 6.15.00 baseband. I have need of GPS for an upcoming trip, so I decided to finally try to downgrade my baseband with then newish redsn0w. I tried to use the instructions at iclarified at http://www.iclarified.com/entry/index.php?enid=22653 Things did not go according to plan. I tried to do the downgrade iPad baseband using the 5.0.1 baseband. I got a message about the machine not being able to download the baseband files or some such thing, and now it is stuck in recovery mode and I can't seem to get it out. Redsn0w recognizes the iphone as 3GS (Recovery mode, old BR) Tiny Umbrella says that I have blobs for 4.1, 5.01, and 5.1b1 (side note - what is this, how did I get it when I never upgraded to 5.1, and will it do me any good?) Redsn0w and Tiny Umbrella are both unable to get me out of recovery mode. Can I somehow create a custom ipsw to recover from in iTunes? What else can I do? PLEASE HELP - I'm too poor to be able to buy a new phone.
