Hello guys,

i' trying to restore my JB iphone4 to 5.0.1 or 5.1.1. I have latest iTunes. I' ve tried fixing hosts but then i'm getting error 11. I have saved Shsh, tried with tinyumbrella and redsnow custom IPSW, but still can't restore. Any ideas? Could it be my pc's hardware? Iphone is fully functionable but a bit slow.Thanks in advance.
