Hello, I'm trying to downgrade my iPhone 4 running iOS 4.2.1 to 4.1. I've downloaded the 4.1 IPSW and have the SHSH blobs for 4.1. I've tried to restore twice now but always get an error at the near the end of the process. I have TinyUmbrella's TSS server running. I've read on a few sites that I should just kick the phone out of recovery when I get the error and it should be successfully downgraded. Is this right? Any help is greatly appreciated. Thanks
Yep when you get that error message open Tiny Umbrella and hit the “Exit Recovery” button. It'll restart and then your done.
