try downgrading to a lower iOS,then reinstalling.
here's how:
get tinyumbrella,ifaith and iREB. use tinyumbrella to get your SHSH blobs and stitch them to your IPSW with ifaith,then go to pwned DFU with iREB and restore!
if your iOS 5.1 SHSH blobs don't exist or anything iOS 5,that means your iphone has not been on it,and there's no way to get them back. |
