Hi all! I need firmware for my mp3 player, because it's got broken! Here are the pictures of

cpu
Rockchip RKnano E33886 0936 or E33888 0938

memory
SAMSUNG 922 K9GAG08U0M

and Motherboard
0936 FC1772020.
Through the program that you can edit the firmware files, extract them?
I spread the firmware from the player that does not have the correct keyboard driver.
firmware not_correct
Please remove all that you can from it and tell me how to build back.
