I bought an MP4, is a 3" touchscreen, 16GB mp4 player, It has a RockChip thingy and the Board IDnumber is CR3009TF-V1.2. I wanna know how to get the correct firmware and how to revive it cause it died. It no longer turns on, but still the PC reads it as a pendrive. Thankies in advace ><. Also, this is besides the point... is there a way to change the firmware/the display configuration? (pictures, theme, icons)
