[Q] Capacitive Buttons Stopped working, Help installing soft keys topic

Hi my Telstra HTC one XL has had its capacitive keys stop working over the weekend. Before I attempt any hardware fix I had hoped
to enable the default android stock keys so that the phone is still usable.

Thus far I have unlocked using HTC dev.
Installed TWRP
Gained root by flashing SU
Used Rumrunner to for S-Off

I have then attempted to change the build.prop to add qemu.hw.mainkeys=0
Upon restarting the device this did not work.
I then tried SB buttons (root) from the play store and another by a similar name
these also did not work.

Is it possible to enable the softkeys on the stock ROM?

At this point I am just looking for a usable phone so I am trying to install Cyanogen mod (taking forever because I forgot Gapps and now have to download that) in the hopes I might have more success there.
However I would like to stick with stock sense or a sense like ROM if this is possible. (I like the camera and have grown used to the look and feel).

For reference the following information is shown on my boot loader page

*unlocked*
*tampered*
EVITA PVT SHIP S-Off RL
Hboot-2.15.0000
RADIO 1.889.32.45.24
Open DSPv33.1.0.45.1128
.emmc-boot

This is my first time rooting my phone/ installing customs ROMs so any help would be wonderful.
