My Iphone 3GS was jailbreak and unlocked on 3.0 firmware. When I decided to move over to the official Iphone carrier I did not know about the "signature" blocked from Apple (itunes). So, in attempt to erase all data at once from my 3GS, I reset it "Erase all content and settings" the iphone went into Recovery Mode and I couldn't get out of it, without knowing about the Itunes signature, I tried to restore and as you know it didn't work. Now, I've tried all I red on the web "Snowbreeze, blackrain, unbrella, Usbview" Nothing since to work . The Iphone will not restore in Itunes at all. I tried to save my SHSH but I get an Umbrella error saying "Could not get your ECID SHSH for that model/version:sorry". Please Please help.

Any help would be glady appreciated.

Thank you.

A 3GS iPhone that was jailbroken and then wiped via erase all content and settings should be able to be restored in Recovery mode with a custom IPSW. Don't use DFU mode.

Sn0wbreeze custom ipsw should in theory work but it is not supported on this forum.

Aside from that - your only option is to restore to iOS4.0.1 and wait for a new jailbreak.
