Hello People,

I have successfully upgrade my teclast tpad p81hd from android 2.3 to the latest android 4.01 firmware.

The latest android 4.01 able to run and install but the problems are:

1) unable to turn on the wifi -> wifi driver problem?
2) unable to turn on the Bluetooth -> Bluetooth driver problem?
3) unable to use camera

I heard there was a bug in android 4.01 related to SIM card region issue which can cause other devices to be malfunctional . This problem can be solve if I have root access or rooted my ICS or firmware.

But currently, my firmware do not have root... therefore are there any solution to my problem?

Thanks
