In the attempt of updating my iPhone from 4.01 to 4.3.3 using Sn0wBreeze (as to preserve my baseband because I'm with T-Mobile) I seem to have put my phone in a boot loop. After I shift restore in iTunes, I get a message that says my phone has been restored successfully, but then iTunes gives me another pop up that says it is in DFU mode again. I have tried using Tiny Umbrella, but to no avail it is still in DFU mode. If anyone can help me, please do!
