Button Remaper. Haven't tried it myself, someone posted it in my Tablet UI mod thread. Let me know if it works.
Works fine just wish there was more to choose from.

The key layout is the beginning but it will also require framework edits to PhoneWindowManager to change the function of the APP_SWITCH function.

The backlit "search" button on the lower right of the t989 screen gives me no end of trouble. Several times a day, I'll accidentally press it with my palm while doing any number of other things. This interrupts whatever I'm actually up to and always causes me have to start over in, for example, the middle of a long forum post.
What I'm looking for is some way to disable that particular key. Is there an app for that? Or some other hack?
Thanks,

I recently installed CM 9.1 on my T989. Searches during the last few days have revealed 9.1 as the most recent stable CM for this phone, and "hardware keys" isn't anywhere in these settings that I can see. What's the trick here? From what I can tell, CM10 isn't available for the T989. How new do I need?
It is most certainly available.

Code:
# key 158 BACK
# key 139 MENU
physical home button, however, will still wake up the device (which i prefer) and long pressing on it will bring up s-/google- voice. if you wish otherwise, you can disable it altogether by editing the line on gpio-keys.kl (same directory as above)...
Code:
# key 172 HOME WAKE
then turn off lights via settings/display/touchkey light duration. works on both ics and jb sammy roms. HTH

so if you change key 158 to be menu and 159 to be back will the keys change to it as specified?
Great Mods Rein..Worked perfect.
Man, that's killer. Thanks so much. I was actually scared doing that. Never messed around in there before. So, the soft keys are there & I just went into settings & just turned the light off to the hardware keys, but let me get this straight please, all I have to do to take the sofykeys away is turn =0 into =1, that's it (& reboot) TIA & thanks again for this.

Hello if i enable the softkeys everything works after the first reboot but after the second reboot the softkeys and the line inside build.prop is gone!
Is there a way i could set it permanently?
I thought i could use a .SH script wich adds "qemu.hw.mainkeys=0" to the build.prop every boot? But i don't know what to write?
Would something like this work?
Placed in init.d as 999softkey.sh

you need to be rooted to do this and you have to do it with a root explorer, my favorite is total commander in the play store, it automatically detects you are trying to save onto a routed folder and asks for permissions

I have the At&t version of Optimus G E970, I think this will work for any Optimus G.
Not responsible for bricked phones.
This is a mod how to enable navigation bar(on screen buttons) , its very simple and easy...
To edit build.prop, on root explorer navigate to system press and hold on build.prop and open in text editor.
Add the following line at the end of build.prop file
qemu.hw.mainkeys=0
now on reboot we will have nav-bar like on nexus 4
To disable hardware keys, I used root explorer go to system/usr/keylayout click and hold on kaypad.nl and choose from menu open in text editor and 139,158,172 edit the home to hom and do the same on all 3 lines and hit save and reboot,
Plus I went and deleted all the 139, 158, 172 lines from external_kbd.kl, Generic.kl, MHLRCP.kl, osp3-input.kl and qwerty.kl. I dont know if that helps because I deleted them first then edited the lines in kaypad.nl.

The easiest way to disable the default navigation buttons is by going to
system/usr/keylayout/keypad_8064.kl When you open the file you'll find
key 158 BACK VIRTUAL
key 172 HOME VIRTUAL
key 139 MENU VIRTUAL
add a # in the begging of each one like
#key 158 BACK VIRTUAL
#key 172 HOME VIRTUAL
#key 139 MENU VIRTUAL
Reboot and they should be disabled, but the buttons still light up. To fix this go the settings/display/front key light Then uncheck
Turn on Front Key Light.

Also noticed that when I reboot my phone the first notification I get shows up normally, then they stop showing. It notifys me and everything, just cant pull down the blind to access them.
Also noticed that my menu button isnt integrated with the menu bar at the bottom. Ideas on how to do this?

I can't answer the notification issue, but I believe for the menu button a lot of apps have a built in menu button (usually in an action bar on the top right) now that they display (it is more of a tablet display, but given the resolution it probably still shows up that way).
You can still get to the menu in apps right?

Even though there is a tutorial that has been posted on this before, it is somewhat old and buried.
THIS DOES WORK ON ALL BUILDS OF TW BASED JELLYBEAN
You will need to do a few things before we start.
1. Go HERE and download the latest version of LMT Launcher. It would do you justice to also read that thread to understand the installation and setup process for the Pie Controls. Do all of that and then move on to step 2.
2. Grab this file and place it on either your external or internal SD card.
3. On your device, use any root filemanager of your choice (i.e. ES File Explorer, Root File Explorer, etc.) Find the Generic.kl file I included and copy it. Navigate to system/usr/keylayout and change the file called "Generic.kl" to "Generic.kl.bak" (DO NOT DELETE IT) then paste the Generic.kl file that you copied.
4. Go back to home and then go to Settings/Display/Touch Key Light Duration and select Always off.
5.Reboot your device and enjoy.

Actually, no. It doesn't locate itself, so I'm not able to use camera as is. Downloaded after market camera to use in the mean time, but really like the camera that came with jv. Lowering the dpi sounds like a viable option. I'll look into it this evening. Thanks for the idea DEF3NDER.
