Want to get my JB phone up to at least 4.0.1, so I have downloaded the "iPhone2,1_4.0.1_8A306_Restore.ipsw" file in order to do a Shift+Restore to get my phone to that firmware, and then will JB it from there either with using BlackSn0w or jailbreakme.com. However when trying to do that through Itunes 9.2.1.5 . It fails with a message saying "iphone could not be restored unknown error (3194)"
Any ideas on where to go from here?
