Atv2 jailbreak 5.3 restaure

Hello, I have a ATV2 jailbreak ios 5.3 unterthered. 

But recently I have problems with Vevo I am unable to access playlists and adjustments? I can play video and do research but more remains to enter! the wheel turns for hours and nothing? 

I tried to reboot respresing and even unplugged the apple tv but nothing could be done? 

Yet it worked iMeme with jailbreak since January and suddenly no longer want! 

then I said to myself more than to restore and re jailbreak? 

unless I can remove and reinstall Vevo? 

I cyberduck 

I installed xbmc and I had 2-3 crashes otherwise works tip top except that Vevo is only half?

just precision i m french
