I noticed the link you gave was for a Droid Ultra. I didn't feel comfortable dropping in a build.prop for a different device, so I inspected the file and figured out the one-liner that is needed (probably for all Motorola/Kitkat devices):
net.tethering.noprovisioning=true
So, here are some slightly revised 'generic' instructions:
1) Delete/Freeze VZWEntitlementServices.apk and VZWEntitlementServices.odex in /system/priv-app/
2) Backup /system/build.prop
3) Edit /system/build.prop and insert the line above if it does exist. I'm not sure if placement matters, but it was on line 309 for me. Here are the lines above and below it for me:
Please Login or Register to see this Hidden Content
4) Double check the permissions are 644 (rw-r--r--) (very important!)
5) Reboot
For me I drop in a newly edited build.prop and the permissions were 666 (rw-rw-rw-) and my phone no longer booted--oops. If you do this, the fix is somewhat easy:
1) plug in phone to computer via USB with it on the blank booting screen
2) fire up a window to run adb (hopefully you set this up already)
3) run
