Aqui una posible solucion al menos a ellos les ha funcionado:
Hi,
I had a similar problem, get the protab2xxl_compatibility_1.1.0.zip and then follow the instructions in this post:
you should unzip the protab2xxl_compatibility_1.1.0.zip, mount /dev/block/nanda and push script.bin and script0.bin, after reboot you should be able to see the display again (and you can use cwm to flash the whole compatibility zip)
place script.bin and script0.bin in the folder where you have adb (I used QTadb)
Then follow these commands (you should still have root)
adb shell
su
mkdir /sdcard/nanda
mount -t vfat /dev/block/nanda /sdcard/nanda
exit
exit
adb push script.bin /sdcard/nanda
adb push script0.bin /sdcard/nanda
adb shell
su
umount /sdcard/nanda
and then reboot
Worked for me
Dime si te va ....espero que si
