Apple TV Jailbroken. 4.3 Software. aTV Flash Black Stuck while Installing

Hello. I just jailbroke my Apple TV 2 and updated it to 4.3. I am trying to install aTV flash black but it gets stuck while installing every single time. 

This is the screen it gets stuck at:

Does anyone know what is happening or how I can get it installed? Thanks.

Nevermind, I figured it out. I tried to ssh into root@appletv.local and was getting and unknown RSA host key. I went into the known_hosts file and deleted everything, got ssh working then tried the atv flash again. Worked perfect.
