Hi,
You should definitely do a proper 'reformat' of your previously hacked player. And you really should try and let Ebay know you've been conned, as they have once again let someone get away with ripping off the public :x
A member called 'Lattesurf' wrote an excellent guide on reformatting, found here:

It's important to do this, as your player may freeze indefinitely.
I also bought a player like your one - I knew it would be hacked, but i was curious about the design / Nokia changeable battery.
After carrying out the proper re-format, it dropped from '2GB' to it's proper 1GB size.
The TFT is very bright and vibrant, as as such, I use it as a pocket image viewer (I have no interest in its AMV format capabilities as I am a true Rockchip convert!!).
On the audio front, I've noticed there's quite a lot of 'digital noise' - especially when the song title is scrolling.
Good luck!!
