Downgraded from iOS 5 Beta 3 back to 4.3.3 - No Carrier Now.

[mingistech]

Hello

I have saved SHSH blobs for 4.3.3 saved so the downgrade was simple. I had to go from iOS 5.0 Beta 3 > 4.3.4 > 4.3.3 because when going down to 4.3.4 the phone will revert to the old baseband, then you can take it back to 4.3.3 for the Jailbreak.

All this worked great except for the fact that I no longer have cellular data. I can make calls over AT&T without issue but no 3G or Edge.

I've done the obvious of resetting all Net Settings.

Any idea for a fix?

Thats an iTunes restore error. This problem is usually caused because iTunes is not actually talking to the Apple signing servers to get SHSH blobs, but is more likely pointed towards Cydia. This is usually because you have previously used TinyUmbrella to store your SHSH Blobs or you edited your hosts file manually to point to Cydia.

Here is a guide that might help you with restore.
