Hardware

 * 2x DDR3
 * Micron NAND (later versions of PCB uses SANDISK and Toshiba)

Taking apart
Just insert something like plastic card in gap between case and LCD housing - there is no screws. Tablet PCB mounted on LCD housing assembly, backplate is different on OEMs (shape, logos & etc).

Hacking
As any A13 device, for example, A13-Olinuxino. Info will be added soon after testing.

Firmwares
Ask firmware from your seller, OEM's have different touchscreen EEPROM, flashing wrong fimware will kill it.
