If that doesn't helps :
your player is already dead,
so, there're a lot of firmwares available,
just try to install one after another,

Also, you can go to the Google Pictures,
type "RK2608" and search for the player
with the similar main menu. And then
try to find the firmware for this player
and install it to your player.
