This page needs to be properly filled according to the New Device Howto and the New Device Page guide.

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.

This section explains how to most easily identify your device. For a development board, explain the name(s) printed on the board. For an android device, find out the strings as reported under settings.

On the back of the device, the following is printed:

Manufacturer Marketing Name
ModelNumber

The PCB has the following silkscreened on it:

LIA-BB-V6.66
1970-01-01

In android, under Settings->About Tablet, you will find:

Model Number: A710
Build Number: crane_a710-eng 4.0.3 IML74K eng.liushen.20120209.115637 test-keys

Tips, Tricks, Caveats

Add MANUFACTURER DEVICE specific tips, tricks, Caveats and nice to have changes here.

FEL mode

The something button triggers FEL mode.

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. Log:

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.

Adding a serial port (voids warranty)

DEVICE UART pads

This section explains how to attach a serial port to the device. Make sure it refers to our UART howto. For a development board, you can just mention how to find the header with the pins and include a picture, and you can remove the warranty voiding warning.

Device disassembly

If necessary, provide a short description of how to open the device. Perhaps explain how the pins can be most easily popped. If pins do need to be popped, mention the Plastic tool howto.

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).
