Try a custom IPSW.
Create a 5.1.1 NO_BB IPSW with redsn0w, then enter device into pwned DFU and run the IPSW.

If still error, try to create Hacktivated IPSW with sn0wbreeze.

if you iphone factory unlock try update 5.1.1

Error 9
Due to asr being patched, the SHA signature is automatically changed and after being resigned the kernel will refuse to use it. Therefore proper kernel patches are required. If necessary kernel patches are not applied, it will fail to load asr and error 9 would occur during restore.
Rebooting your PC may resolve this issue. Aslo it can be connection issue.
