Can't exit recovery mode? How do I switch from recovery to DFU?

[sofakng]

I'm trying to downgrade from iOS 5 beta 3 to 4.3.3.

I've used TinyUmbrella and restored 4.3.3 with iTunes however I received the 1013 error and my phone is now stuck in a recovery loop.

However, TinyUmbrella can't kick the phone out of recovery mode. When I try, the phone just reboots and it's still in recovery mode. I think I can use DFU mode to exit recovery mode but how can I do this?

I can't seem to enter DFU mode from inside recovery mode.

I used Greenpois0n to get me out of recovery mode when i downgraded from 4.3 to 4.2.1!

You could try what ever it is that can JB 4.3.3, that might do it.
