Added some images so i can be easier to follow 

This is how i setup my android phone (Samsung galaxy mini) to work with nVpn.

First you must have root and have Busybox installed.

Lets start with the files you need which is tun.ko OpenVPN-Settings-0.4.7.apk OpenVPN-Installer-0.2.3.apk and they are in this package

After you download these files transfer them to root of sdcard.
Start your terminal if you dont have one download this

Now type this in the terminal so you will remount your systemfolder so you can copy files to it


su
mount -o remount,rw /dev/block/mtdblock4 /system 
cp /sdcard/tun.ko /system/lib/modules/tun.ko

If you have SSH droid installed you can connect to your phone with putty and do these commands there.
Username is root and password is admin

Now you have the tun tap driver installed.

After that you install OpenVPN-Installer-0.2.3.apk and launch it and if all is ok just click install.

And then you install and launch OpenVPN-Settings-0.4.7.apk and it will ask you to put your .ovpn config and cert files in /sdcard/openvpn and you only need to copy your files there.

Restart openvpn-settings and it should work fine and connect to this vpn
If you get this error FATAL: cannot allocate tun/tap dev dynamically
Use this line: insmod /system/lib/modules/tun.ko


And if you dont like to type in username and password everytime you connect to the vpn create an nvpn.auth file and add your username and password Like this:
Username
Password


And add this to your .ovpn file. auth-user-pass nvpn.auth and it will connect automatically
