changes to build.prop not saving, reverting back to stock build.prop every time

I've seen a few threads about this, but my problem is a little different. I can edit my build.prop and save the changes. however, when I save and exit the text editor and build.prop and go back in, the changes don't stick. I'm on 6.0 with beta superuser 2.51 and elemental 3.0 for what its. anybody have any ideas?

[Help] Phone crashes on every single custom rom

I have the d851 T-mobile variant with 3gb, and while I have no issues flashing whatever rom I want, none of them happen to be stable. Originally my phone would just turn off and I would have to perform a battery pull to bring it back. It could happen at anytime, while it's sitting on my desk without being touched, or just browsing facebook. I bit the bullet and installed the official OTA and rerooted the phone and tried a number of other roms. They still crash, however I have been presented with a crash manager that allows me to reboot with the volume key instead of having to do a battery pull. Even the touted Cloudy G3 rom crashes on me. Quite literally, the only rom that works is stock. I have been searching everywhere for an answer and my eyes are about to bleed. I have never seen anything like this...does anyone have any insight?
