    You should downgrade your baseband, then do the update.

    You would have to stitch the SHSH blobs to the 6.0 IPSW to create a custom IPSW using redsn0w.
    Throw the phone into pwned DFU mode, then update using that custom IPSW.

    if 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

    do you still want it jailbroken? if so, restore to 5.1.1 if you have shsh blobs for that version for your device. your iOS 6 shsh blobs are no good so if you don't care about jailbreak, restore to 6.1.3 which only has a tethered jailbreak for your device
