Help rooting Sonim XP7?

Hey smart people!

Anyone know how to root a Sonim XP7? I will gladly donate something to your favorite charity if your rooting solution works!

So far towelroot.apk doesn't work. I know how to use ADB but don't feel comfortable pushing a new boot loader without being able to backup and restore the existing one.

Here are some numbers from the About phone tab
