i've used your guide, thanks it works...the only problem i get now, is screen on/off (screen doesn't switch on after a screen lock or sleep..i can hear email notifications when i send it a mail)
this happens only after i flash Task 14..doesnt happen on the stock ROM for unrooting
so, i used your guide but instead, used Asian firmware to flash stock rom..however CWM screen flicker is back, and the only way for me to flash Task is to use Overcome CWM
I will maybe try your method again and flash ICS (just to test since i really need the camera)
I'm now really thinking there is something in the Asian Tabs that is doing this...
