I have an old bottom 3GS that worked fine unlocked with ultrasn0w and activated through SAM on iOS 5.0. For GPS reasons, I wanted to get rid of the jailbreak (and the unlock). Without too much research I thought that a Factory Reset through iTunes would do the trick. However, it is apparently not possible to get rid of the new baseband 06.15.00, and since it is no longer JBed, the iPhone won't recognize the BB. Thus NO SERVICE.
With redsn0w, i tried to rejailbreak it with following settings:
-Select IPSW (stock ipsw 5.0.1)
-Install Cydia
-Install iPad Baseband
-Deactivate
This only makes redsn0w crash. Therefore I tried to only Install Baseband, which works, and makes the iPhone at least recognize whether there is a SIM card or not in the phone, but won't still give me any network service.
Trying to only install Cydia or deactivate leads to "ERROR 6000ms".
So, I tired instead to restore through iTunes a custom sn0wbreeze_iPhone 3GS_OBR-5.0.ipsw, but to no avail.
Any ideas on what I could try to get my phone working again would be greatly appreciated!
