Hi Folks, I am having Micromax A57
rooted and I wanted to install tun.ko for
it!! So I headed of to play store
downloaded tun.ko installer and open it,
it searched for a while and then said
"module not compatible" Thereafter I
searched a tun.ko and what I see is that
in the droidvpn repository database, a
tun.ko for my phone with the said kernel
and android version is available but when
I download through the installer it
doesn't install!! Any way I could manually
download it or any other I can get
through it!! I want to use droid or
openvpn!!
Here is my kernel version - 2.6.38.6-perf
+ Build LQAEB26.1.0_W120807 and
Android Version 2.3.5!!
Please help me!!
