echo 900 > $dev/button-backlight-rgb2/max_current #Max current in uA

To this -

echo 1 > $dev/button-backlight-rgb1/max_brightness #Max current in uA

echo 1 > $dev/button-backlight-rgb2/max_brightness #Max current in uA

Reboot and enjoy.

Second way:

Download this:http://www.mediafire.com/view/92czo8qz16zvhi2/65DisableKeyBacklight
