I tried to upgrade my iPhone 4 from ios 5.0.0 To 5.0.1 reserved baseband 01.59.00
I use sn0wbeeze to created custom filmware then put it in DFU mode. Open itune press Shift and restore. I did try anything I know and
I got different error from iTune 21, 2005, 1600. If someone know how to solve that problem please share with me . Thank you.



Edit: Problem solved. I try with another computer and it worked fine. Thank you.
