Everything is gone from my ATV2

Today i experianced something wired.

I plugged my ATV2 out and tok it to my other living room, plugged it in and my jailbreak was gone?

XBMC and NitoTv was also gone(of course when jailbreak was) i had the latest seasonpass and flash from firecore.

I coulden´t get in to ssh eather, has anybody any solutions for this problem
