Firmware Upgrade ATV2 currently at 4.2.2

I currently have the jailbroken ATV2 with firmware 4.2.2 from Apple.  I have the current ATV Flash.

 

I’ve noticed for quite some time that I no longer see music or TV Show menus. These are in fact turned on to view in the Maintenance Menu.  i have fiddled with the country settings (I am in Germany with a US Account). However this has not caused the menu’s to return.  I also noticed my friends have the option to stream old iTunes purchases from the cloud but this menu also does not appear for me.

 

Can someone explain to me the steps for getting my ATV 2 firmware to the latest and greatest?

 

Thanks

My apologies, I should have searched better in the forums.  I realize now i have to re-jailbreak.  

 

Thanks!
