Every time I try restore my 3GS I'm getting error -1 after the restore is complete and get on recovery mode.This happened after I tried Preserving baseband from 4.3.5 to 5.0.1.Can't unstuck,Doing Restore to Factory Settings the normal restore to (5.0.1).Tiny Umbrella doesn't work,been trying to get out of this for a week now I'm afraid my iPhone is dead?Would appreciate help.

Thanks
