Are your blobs from that phone ?

Your baseband is causing the errors you need to upgrade with a custom Ipsw then it wont try to change your base band and stitch you for blobs for 6.0

but if the baseband is the problem then why IOS 6.1.3 is restored successfully

ive downgraded the firmware to 5.13.04 and stitch blobs to IOS 6.0 but it again gives errors
iTunes gives 11 and 1604 error
while redsn0w said that no shsh blobs found while restoring the custom frimware
