Sudden problems with atv2

i seem to be having problems with a few of the features on my jailbroken atv2 running aatv flash black 2.4

The first one is that I no longer get cover art on new movies but the metadata works fine,

Also backing up my settings and installing Kodi both fail.

The other thing I’ve noticed is that using couch surfer forces the atv to reboot.

Are there any other updates available for the atv or do I have to re jailbreak it.

Thanks
Shane
