Hacking
ProTab2 XXL runs miniand.com, doozan.com, a10linux.org and tinycorelinux.net SD card images and Linaro. You need the script.bin from stock firmware. This is with corrected touchscreen dimensions from Android 4.0.3: https://www.dropbox.com/s/6scdp37kqgg9tw5/script.bin%2Bfex.zip

FT5X touchscreen issues
To make ft5x touchscreen work with X you need to recompile ft5x_ts module as described at Rhombus Tech after commenting out CONFIG_FT5X0X_MULTITOUCH in drivers/input/touchscreen/ft5x_ts.h.

The module is availabe for kernel 3.0.39+ here: https://www.dropbox.com/s/7im0c23n7lu3ujh/ft5x_ts.ko

The screen dimensions and axes will be confused. You will need to change your script.bin as described at eLinux.org like following: ctp_screen_max_x = 600 ctp_screen_max_y = 1024

Axes can then be swapped with the Debian package xinput by running: xinput set-prop ft5x_ts "Evdev Axes Swap" 1
