You find file on sd card by using root explorer, unzip it, then click menu, and click multiselect that allows you to click 1000 1100 1200. Then click move. Go back to system, under system find xbin, then hit paste. I'm sorry I don't remember where I got zip from. After that install setcpu, I leave max at full min at300 you can set both at max but then you are running 1200 all day. Go back to system, xbin, click 1200 and select Linux script handler, click execute.
