Hi everyone im a newbie, i just need some help with all the experts here i hope you could give me clear instructions to follow on updating my ott 4k m8 mbox media player. The issues im having is when playing movies on XBMC sometime the movies freeze but there still have sound it happens only on some of my sd movies but the hd movies i dont get issues.

I have been looking for some firmwares of my unit but i saw lots of it and i dont know which one is correct for my player. Also my remote is not working anymore its suddenly doesnt detected by my unit. Is there any stable firmware for this player...see mine below
