- added Powersave governor

Info:
default governor is Interactive with scaling from 245Mhz to 1497MHz

How to install
1. unpack downloaded ZIP file (for example to d:/temp)
2. connect device with computer with Android SDK tools (adb, fastboot)
3. reboot to bootloader

Hi Kamma, looking forward to giving this a try! At 1.49ghz what voltage will t be at, how much overvolted or undervolted if thats even possible? lol

Click to expand...

Click to collapse

because of stability a use same values as cyanogen in visoin kernel :

{ 1017600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
{ 1113600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
{ 1209600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
{ 1305600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
{ 1401600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
{ 1497600, PLL_2, 3, 0, 192000, 1300, VDD_RAW(1300) },

Please could someone help, I have completed 1-5 no problems, but when trying to push the wifi module I get this

Any help much appreciated

you dont have rooted device ?

muzens said:

I have permarooted with S-OFF, root apps work fine (setCPU, root explorer, SuperUser etc.)

Click to expand...

Click to collapse

did allow adb to gain root access ?

muzens said:

Maybe be a stupid question, How do I allow it?
Thanks for your help

Click to expand...

Click to collapse

if you start any application, which wants to gain root access, for the first time, then SuperUser app shows you dialog where you can allow or deny to gain root.

if you already denied to adb gain root, so you have to clear it in SuperUser app.

muzens said:

I have allowed other apps, but ADB hasn't shown up, nor is it in the list of the allowed apps.

i dont know then...
it should look like that :

Great stuff (kernel is working here) little question, the 1ghz clock is according to your post 1200mV, I thought default was 1100mV?! (Source: http://xdaforums.com/showpost.php?p=9150605&postcount=14)

If so, can't you lower the 1ghz clock to use 1100mV, since this is the default which is tested by HTC

Im not sure about default voltages. But i can build experimental kernel with lower voltages.
