ATV Flash wiped out the jailbreak

I installed the new untethered Jailbreak on my ATV2.  I then installed ATV Flash.  When it rebooted the Firecore logo on the settings box was gone so I now think somehow it overwrote the jailbreak. 

Nope, the firecore logo goes when you install atv flash.

You should now have a ‘Maintenance’ box where you can install xbmc, media player, browser etc…
