Open the player
The shell of the player is in plastic. No screws, only small plastic hooks.
With a very small screwdriver, start to gently force close to the bottom angles of the player, where the USB connector and phone connectors are.
Then very gently start to work all around the border of the player.
A certain point it will be possible to user the fingers to gently separate the shells.
The inside
After the shells are separated, the PCB and the battery appears (the gray "thingy" on the right).
3 big chipsets are visible, plus the microphone and the pinhole camera.
Also the micro SD card reader, the USB connector and the headphone jack are visible,
The three chipset are so marked :
- ATJ2259C - ZC55LBB B7A
The microcontroller - So far I was unable to retrieve datasheet or even basic information about this controller.
It is a Chinese processor and in the typical Chinese way, no information are released.
Pity. We should really stop to buy stuff produced in China. - Infineon HYB39S25616odt
HYB39S256160DT-7 - 256-MBit Synchronous DRAM - PF369 - AR - 1134
Probably LCD/touchscreen manager but like the processor I was unable to find information.
Device is from CSDN.. hard to read due to language of site :(((

The other can resemble a ram or similar too TS controller usually are 8 pin.
