Code:

Most of you would want to skip to Step 1.3 as that's why I created this post and everything else is almost similar. If this works out (especially 1.3), please give me feedback.[/B] 1.1 Enabling softkeys: 1. Make sure you have got / & /system mounted as rw. 2. Go to device/system/build.prop. 3. Scroll down to the extreme bottom. 4. Add this line there : qemu.hw.mainkeys=0 5. Save the file and reboot. (To be sure that it has got enabled and we're gonna disable the hard-keys in the next step.) 1.2 Disabling the Hardware keys: 1. Go to Device/system/usr/keylayout/generic.kl. 2. Scroll down and find the following keys and add # before each of them. It should then look like this: # key 139 MENU # key 158 BACK # key 172 HOME 3. Save and Reboot. Alternatively you can go set the long press and short press of the hard keys to "No action" from settings , in newer builds. (But back button would still work though) 1.3 Disabling the backlight of the HW keys: (Permanent as long as a systemless SuperSU is available.) 1. Download this :- https://www.dropbox.com/s/lbx8fogscy...Backlight?dl=0 2. Have a systemless version of @Chainfire 's SuperSU flashed (very important) 3. Go to /su/su.d 4. Paste the "DisableSoftkeysBacklight" you downloaded inside su.d 5. Change permissions of the file (Give Owner read, write and execute permissions.) 6. Now reboot.
