Hi,
I want to disable the soft-keys (those beside the hardware home button) and their back light in CM10.1 Rom.

Actually I want to use the Navigation bar (interface soft-keys) just like in nexus devices.

But the official CM10.1 Rom doesn't has any setting to enable navigation bar . And there is no advanced settings to disable soft-keys back light or to disable soft-keys.


I managed to enable Navigation bar and disable soft-keys by following this thread . But the soft-keys back light is still present.

Next, I followed this thread to disable soft-keys back light. But it didn't work. Infact there is no such setting as this ( <bool name="config_autoBrightnessButtonKeyboard">true</bool> ) in bools.xml. I tried adding that new line with no result.


So, how can I disable soft-keys backlight ?

Go on dialer and type
3845#*YOUR VARIANT PHONE MODEL#
Click to expand...
Click to collapse
for example mine is p769. I type 3845#*769#. After, go on "H/W device test" and scroll down till you see Touch Led brightness and select off.

run this as su

#!/system/bin/sh
#disable Key Backlight
echo begin set Key Backlight - KB
echo KB - set permissions rw
chmod 0666 /sys/class/leds/button-backlight/brightness
echo KB - set Key Backlight 0
echo "0" > /sys/class/leds/button-backlight/brightness
echo KB - set permissions ro
chmod 0444 /sys/class/leds/button-backlight/brightness
echo KB - done!

I can't find hidden menu in CM10.1 with this trick. The menu appears in stock rom.

That worked. Thank you so much. . But the setting is lost on reboot. I have pushed the script file to /etc/init.d/ to start the script everytime on boot.

I'm attaching the recovery flashable zip file below incase anyone needs it. Flashing it from recovery in CM10.1 ROM disables the softkey backlight .
