Did you follow the instructions?
Flash the kernel (ignore the boot time, we can't do much about that at the moment). When its booted, turn the screen on, unlock it if you have a lock, then turn the screen off - then start to use your phone normally.
Each time you reboot you will have to toggle the screen on and off again before the 'fix' kicks in.
