flipout (rooted), conservative and powersave module of cpufreq

flipout has no compiled conservative and powersave of cpufreq in kernel.
but we can use compile kernel for modules.

module files:
cpufreq_conservative.ko
cpufreq_powersave.ko

BTW: flipout must be rooted.

xt502 CM7 z71 phone driver

when xt502 with CM7, the device become to z71 phone,
XP can't recognition the driver,
so we can use Google USB Driver package to install the driver.


1. download android SDK
2. use Android SDK Manager
3. in Extras, install Goole USB Driver package
4. the driver data will generated at extras directory
5. edit android_winusb.inf
the drive identify should be VID_0489&PID_C001
add to x86 or amd64


;Z71
%SingleAdbInterface%        = USB_Install, USB\VID_0489&PID_C001
%CompositeAdbInterface%     = USB_Install, USB\VID_0489&PID_C001&MI_01
;
6.install android_winusb.inf
