[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] sufie cruise:
Try these build.props for better management... always make backups before messing with the system files...

And yes this is not my work I'm just sharing it with ypu people...

To get around this copy your build.prop from /system to your SD. Then transfer it from SD to the desktop of your computer after your comfortable with the edits; move the "original" one in the SD card to a new sub folder which probably want to name "original prop" then copy the edited one to the root of your SD then replace the one you have in /system then fix the permissions to 0644 and reboot and profit (you can use gedit on Ubuntu or Notepad++ on windows don't know about mac tho)

Does your phone tell you that you need to purchase an upgrade to your plan whenever you try and tether? Depending on your carrier, this line may help:
