[Micromax A110] andiroxu:
Guys. I created a cputuner script for all devices and not just for MMX. The code is given below. Just copy it in the file and name it cputuner. Run the script using SM. The settings will stick in every reboot.

Note: This is 100% genuine work and don't try to reproduce it any way or no one is allowed to use it their ROM with prior permission.

After all I'm a coder and real developer and love coding and this is known to many of you:cool:
