A710

This device was very popular in 2012, and probably saw many different iterations. It is likely that camera and wifi modules, and battery capacity vary wildly.

The same housing was also sold with a different board inside, namely the A721.

Touchscreen
To make ft5x touchscreen work with X out of the box you need to disable CONFIG_FT5X0X_MULTITOUCH in drivers/input/touchscreen/ft5x_ts.h and recompile ft5x_ts module.

If you flash your LY-F1 with firmware from branded clone (Texet, explay, onda & etc.) or vice versa, you will get your FT5X touchscreen EEPROM empty.

This will lead complete zero response from touchscreen.

Only way to fix this is to flash different firmware to your FT5X. Files and simple .bat script can be found in this archive.

Device disassembly
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).
