So I currently (had) have a jailbroken 4.3.1 iPhone 4 GSM. Now it is just a brick.... I wanted to restore to the new 4.3.3. It keeps giving me the error 1031 and going straight into recovery. I have tinyumbrella and have saved my shsh blobs. I have tried to fix recovery and exit recovery too. Also, I have entered DFU mode (black screen instead of plugin to itunes logo) to try to restore and that didn't help either. I am pretty computer savvy, but somehow these kind of things always happen to me and like me only.... Please help!
