okay ive had it with this iphone 4, i got today running iOS 5.0 and i jailbreak it only to find out that my baseband (04.11.08) isnt supported by ultrasn0w. so i go to restore itunes is stuck at verifying restore with apple when the the bars are moving constantly or whatever. so i get error 1602. I put it in DFU mode, same error. Apparently somehwere throughout this whole thing i got it updated to 5.0.1 when i finally booted with redsn0w. so i was like yayy! so i go to install corona untethered and mobile substrate from cydia and it goes into a boot loop. so i assumed i had to do a tethered boot. so i tried that and it go past the redsn0w pinapple thing and goes to the apple logo and its stuck there. To recap, cant boot with redsn0w, and i get itunes restore error 1602 and 1601. This is my girlfriends phone so it will be really bad if i screwed this thing up. Please help? Much apppreciated!
Put iphone into recovery mode > Turn off and plug in while holding Home button.
Restore to 5.0.1 and jailbreak with redsnow0.9.10b4 ,it is untethered jailbreak.
