How to use

Please read How to use Semaphore JB guide for information about the features

In order to load various modules of the kernel and enable or disable features use Semaphore Manager or HM.Carbide's Semaphore Script Manager application. It automatically copies and runs the respective scripts from /res/scripts to /system/etc/init.d directory. 

Custom Voltage may be configured with Voltage control or similar applications.
