iphone 3GS update from 4.1 (8B117) on baseband 06.15 to 4.2.1 fails
I have an iPhone 3GS that is on fw 4.1 and baseband 06.15. When I try to update it in iTunes I always get a 1015 error. As I have read this is because of the baseband in 4.2.1 is older than the ipad baseband 06.15.
Is there a way to update this to 4.2.1. I have tried to use Pwnagetool 4.1.3 to create a custom 4.2.1 fw but when I select the original 4.2.1 firmware I get an error message wrong firmware bundle selected.
Anybody knows what I'm doing wrong or how I can go to 4.2.1.
I have no SHSH saved unfortunately :S
