So I made the mistake of attempting to downgrade from ios 5 beta 7 to ios 4.3.5 on my iPhone 3gs. I was able to do it on the Ipad 1, i thought it would be as easy...I was wrong.

I option clicked "restore" in itunes to restore to the downloaded 3gs firmware 4.3.5, but it got stuck in a "recover mode" loop (error 1015). The latest versions of Tinyumbrella and Recboot were unable to kick the iphone out of recover mode.

I figured since I couldn't kick it out of the recover mode, I would have to try to jailbreak/boot tethered. Redsn0w froze at "installing activation bundles" for a very long time. I assume it failed, but the iphone managed to reboot itself. I used redsn0w to boot tethered...and now the phone is in "emergency call" mode only.

I think i currently bricked my 3gs...I think i'm going to have to wait for a newer version tinyumbrella/recboot can kick the 3gs out of recover mode.

I'm hoping i'm wrong though. anybody have any ideas?

You need to use the separate "fixrecovery43" tool that is available for download on the TinyUmbrella website. This function is NOT yet integrated into TinyUmbrella.

If that doesn't work, do you have a saved SHSH blob for iOS 4.3.3 or lower? Might be easier to fix if you have this.
