Build.prop hacking - Increase Network Speed, Remove Lags and more!

There's a file called build.prop in our systems. What is it? It's a system configuration file, it tells the system your device's specs and important information. But what if we change this build.prop file to make our devices... better? Check this out.

Yes, it is possible to change build.prop values and it's pretty easy to do. All we need is a root browser, and root access of course.

Let's do this!


  1. Download Root Browser.
  2. Open it, navigate to /system/build.prop and open it using RB Text Editor.
  3. The configuration lines will appear. Here is our workplace.
Let's fake our Android version, for instance. Find a line with your system version in it, and change it to ..let's say Android 5.0. You can also change the manufacturer or device name and download unsupported apps on Google Play!

Let's add some lines. Scroll to the very end of the list and add the following lines.

Warning: Before you edit your build.prop file, make a backup of it, or better make a full nandroid backup of your system in case you end in a bootloop (bad manipulation with build.prop usually causes a bootloop)
