I know for certain that Jelly Belly/leankernel combo supports it as I am running it right now.
Okay, then can you help me figure out what I'm doing wrong here? If I run CPU Spy, for Kernel Info, it says "Linux version 3.0.36-leanKernel-4.0.0-04197-gf36ff07-dirty...", so I know I'm running the right kernel, right? And, it shows my "Time in State" as 1200 MHz, 920 MHz, 700 MHz, 350 MHz, and Deep Sleep, with some time spent in each of them.
Next, I open Terminal Emulator, type su, then type lt. If I choose the "Current Frequencies at Boot" option, it tells me Max is 1200000 and Min is 350000. Does that sounds right? I thought flashing LeanTweaks was support to set it to 1350000/350000 automatically? Anyway, I use the menus to set my max to 1650000 with Highspeed_freq set to Max Freq With Input Boost. Exit out of lt menus and Terminal Emulator. Run CPU Spy again, and it now shows "Time in State" as 1650 MHz, 1200 MHz, 920 MHz, 700 MHz, 350 MHz, and Deep Sleep, with some time spent in each, with unused states of 1520 MHz and 1350 MHz. Then I go back into Terminal and run lt again and can confirm that "Current Frequencies at Boot" is still 1650000 / 350000. Everything looks good, right?
Now I reboot. Bring up CPU Spy and crap. Now it's working. :-) I have no idea what I did differently this time, but it looks like it stuck. Thanks for listening to me ramble...
