I made the WiFi change to the build.prop to try and fix the Wifi passwords issue. I had to change permissions to write and forgot to change it back (I realize this now... lol). I have the backup on my computer and I have access to TWRP (running stock D803 ROM).
Is there a way to flash this file back other that flashing the ROM? Or should I just flash the stock D803 ROM? I want to avoid losing my data.
What is the best way?
