Hi, since last update to 2.50, my X7 Mini is getting stuck once a month. It works like a charm for some weeks, then airpin and xmbc stop working, and at reboot I only get a black screen and it won't boot any more until next firmware restore from RKBatchTools I'm using it just for xbmc , airpin streaming and tunein radio, no strange apps installed on it. Is somebody else having the same issue? Any advice? With older releases I didn't experience any issue, I upgraded just because I needed newer airpin service.
