Hey, I need help with Firmware
 

Hello, I purchased an MP4 player and I wanna know what it is called. Yes that sounds rediculous but i look on it and I see a model number and it says 'Model No:SMPK8854'
it supports rockchip, i know that because i put tetris on it.

My question is, is if there is any kind of "custom firmware" or "Firmware"

thx, plz help.
