Pls post dmesg logs.
Ensure you are inserting the module corresponding to the release version, from /system (lib/modules is a good place for it).
Here is the location of the tun.ko I am using.
\lib-2632.36\lib\modules\2.6.32.36-cyanogenmod\kernel\drivers\net\tun.ko
# uname -r
uname -r
2.6.32.36-cyanogenmod
Nothing displays in dmesg after I run the command.
