If it doesn't show anything on the screen when you power it on, it might mean that your model doesn't work with rockbox for some reason.
However you should still be able to boot the original firmware by holding the left button when pressing power button.
If it's powered on and crashed, you'll need to keep pressing power button for ~20 seconds to make sure it's off, or wait 1 day until the battery empties.
Thanks guys for the quick replies! I'll give it a try.
Considering I only spent around $20 on it, and had for about 8 moths, I am not too concerned.
