[Q] VPN on Tabler with android 4.1.1 (no TUN modul)

When i try to connect vpn it's fail with no info about the error, simply ask that I trust this VPN connection and does not work, there is no key icon on the task bar.

I figure out I do not have a TUN.KO module, so i root my device and load a module from http://droidvpn.com/tun-repository.php, it’s find a module specially for my tablet model
(MC-TAB-1002), kernel load it’s with no problem
lsmod shows:
tun 13357 0 – Live 0x00000000

But .. when I try to establish a VPN connection my device reboot … damn.. maybe I need something else to load or install ? please help
