    Default 3GS Error 21 when restoring to No BB SHSH Stitched 5.0.1

    Hi All

    Im trying to restore a 3GS 3GS New ROM Baseband 6.15 on 4.1 to 5.0.1. I want to preserve baseband.

    I have all SHSH files including 5.0.1, 5.1 and 5.1.1

    So far I have created a no BB 5.0.1 IPSW with redsnow and tried restoring this in PWND DFU mode, this gave 3194
    I then tried the same IPSW stitched with 5.0.1 SHSH this time got error 21.

    I've tried on multiple PC's. Also checked HOSTS file.

    iTunes version 10.6.1.7
    iPhone OS version 4.1
    Platform Windows
    OS Version XP SP3

    3GS New ROM Baseband 6.15

    What version of redsn0w did you use? 0.9.11b4 should be the version you're using to stitch a 5.0+ IPSW.

    3194 is usually that you have stale entries in your hosts file -- make sure there are no entries pointing to gs.apple.com. Error 21 is usually that the restore you're attempting requires either DFU mode or Pwned DFU mode. In your case, you need to both make a stitched .IPSW AND remove the baseband. Your steps make it look like you tried those individually, but you will need to do both together. Your restore of the custom no BB firmware will ONLY take in Pwned DFU mode, and your restore of 5.0.1 will only take if you pre-stitch the .IPSW or use TinyUmbrella to act as a TSS server for it. You're using the proper version of redsn0w to get past the APticket issue, so that should be OK.

    Exactly the same issue here.

    Except I've got a different version of iTunes (10.2.2.14) and resn0w (0.9.12b1).

    I've got the error 21.
    - 3GS with ipad baseband
    - stitched + no_BB custom 5.1.1 firmware with redsn0w
    - hosts file (I tried nothing and 74.208.10.249 for gs.apple.com. I even tried tinyumbrella TSS)

    I really don't have any idea what else I can try...
