iPhone 3GS 5.0.1 Not booting after downgrade from 06.15.00?
I used the iPhone on the iPad baseband for ages, with no problems. After deciding I wanted GPS functionality, I downgraded the baseband using the latest version of redsn0w. Now it isn't turning on, it just stays at an Apple logo for about 10 minutes, black screen, then repeats.
I was tethered on 5.0.1 but installed corona 5.0.1 untether. Should I boot tethered in redsn0w?
Thank you in advance.
(By the way, this IS an older model of the 3GS.)
