1. download the kernel package update.zip (it contains the updated wifi modules)
2. save the package update.zip to sdcard (of phone)
3. reboot phone and enter recovery
4. flash the kernel package update.zip
5. reboot phone and enjoy the kernel

1. start SetCPU/NoFrills CPU Control app on ur phone (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
2. now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
3. DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
4. SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

1. before u report any battery drain issues please read this:
   [GUIDE] HOW-TO Properly Evaluate Battery Life and Provide Useful Reports
   
   
2. faux123 has posted very nice info regarding most features

Just a statement regarding kernel source: The Kernel Source is released for all at GITHUB repo given below. BUT Free software does NOT mean no work or time was spent working on it. A lot of my free time has gone into patching/testing this kernel/features integrated in this kernel. If you use my modified kernel source in parts or in its entirety, I kindly ask you mention its origins and to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source.

Thank you !
