VX858 Onda clone playlists?
 

Recently aquired one of these (Aura branded, 3 buttons on bottom +-M, info says ver 00.00.0003) but i've had a few problems

Shuffle will only suffle about 100 or so songs in a row, if i change artists manually it changes the number of tracks it shuffles. and i can't find any way of making a playlist!

and is there any way of messing with the firmware on it?
