Dump Rockchip original firmware?
 

Hi,
I have an MP4 player, an Irradio Sense. The Rockchip model is RK2608A AE1613, the RAM is an ESMT M12S16161A-LZY1P51XY and the NAND is 29F32G08AAMD2.
My question is if I can dump the original firmware and how to flash it again. I'm a programmer and I'd like to edit the firmware in order to do some experiments (I saw in the forum that an SDK for RK26xx is avaiable).
