3GS Error 21 when restoring to No BB SHSH Stitched 5.0.1
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
OS Version XP SP3
3GS New ROM Baseband 6.15
