broken HW nav keys - AT&T LG Optimus G

my girlfriend just got this phone a month ago, and she dropped it yesterday. theres a little crack on the glass near the nav keys, and now they do not work. i saw a edit for the build.prop to enable on screen nav keys, so i edited the build.prop, and rebooted. now it shows the boot animation, then i get a black screen. i know nothing really about LG phones. im only familiar with motorola devices. i have the original build.prop file saved. i tried to abd push it to system but it says its only mounted as readable. the phone will charge while off, and i can get as far as the red triangle android. i only run ubuntu computers. i do not have a windows PC in my house. what are my options here?

Just a question .
Is your device rooted and has unlocked bootloader ??
What version are you using for the Android ? I guess it should be JB.
Onscreen overlay buttons can be used but It probably needs to be rooted in order to allow it.
And your device seems to have been lost in bootloop. ("Soft Brick")

All I did was root it so I could write system files. I enabled read/write with my file explorer before i changed anything. I did not unlock the boot loader. It is stock 4.1.2 I believe from the factory. I've been searching the net for 2 days now for a restore method on a Linux base with no good results. Like I said in the OP I'm only familiar with Motorola devices really, which have tons of Linux support. If I must I could borrow a windows laptop and go from there. I'm just hazy on which methods are best to use. I want a factory restored fresh out of the box install.

I have no idea about Linux based method , right now. But for a windows base machine you can use LGNPST method for restoring a device back to Box .

So I restored the phone with LGNPST on a friends windows machine. Was a little tricky to get it all installed right, but after 3 attempts it finally worked great.
So more or less what I'm looking for now is a good method for soft keys? I believe the one I tried that soft bricked the phone was for ICS, which obviously won't work. I'd really prefer a app over a mod so the screens resolutions don't get messed up. Anybody have any recommendations? Something that has a trigger sort of like pie I think would be best so its not in the way on the screen.

Search for LMT here on XDA. It's pie with more customization options. Works great.

Sounds good. I'll check it out. Not worried about custom stuff really since my girls hard keys are broken. Just need something functional with home and a back button, so she doesn't have to reboot every time she opens anything.

That will work for you. I have my frequently used apps on it too... makes a nice quick app launcher that's hidden when you don't need it to clean up the home screen.
