I bought this player from china :

It worked perfect for 2 days, then refused to startup (it freezes after beginning of startup animation)
The only way I cab get it to work is connect it to computer via USB, then disconnect it & then it is in view mode.
I have nothing on CD that came with it except programs to convert AVI files.
the firmware indicated is 00 01 0008 date 2007 05-11
if I look at it with explorer & properties it says RockChip.
What can I do?
