samsung-a3-3Getting root access to the root file system on your Samsung Galaxy A3 smartphone means installing more apps on your device. Apps such as the Market Helper offer value that you cannot get without that root access to the internal system on your device. The Market Helper is an app that can completely change the look of your operating system — and it does that without changing the build.prop file.


  • The following guide is made for the Samsung Galaxy A3 smartphone with the model number SM-A300F. You can get to see what your model number is by heading over to the Menu > Settings > About Device > Model Number.


  • You must have a Windows PC to follow this guide for several reasons. The main reason is you cannot use the flashing tool for the Samsung devices if you are not running Windows.
  • Download the Samsung USB Drivers to your Windows computer.
  • You must have the Developer Options menu enabled on your device so you can enter and use the settings found inside.
  • Once you have the Developer Options enabled, find it from the Settings and enable the USB Debugging Mode option you get from inside the Developer Options.
  • You are voiding the Samsung warranty by following this guide. You can restore the warranty by flashing a stock ROM back on your A3 handset; however, that’s only if your are not running Samsung’s Knox security. All devices coming out of the box with Knox cannot ever get the warranty back once tripped.
