  • Boot into TWRP Recovery mode on your Samsung Galaxy A03. You can do this by turning off your device, then pressing and holding the Power and Volume Up buttons simultaneously until the TWRP logo appears on your screen.

  • Flash the GSI ROM by selecting Install from the TWRP main menu, then pressing the Select Image button. Choose the GSI ROM image that you downloaded earlier and select the System partition to flash it. Wait for the installation process to complete.
  • After the installation of the GSI ROM is complete, install the Magisk zip file by selecting Install from the TWRP main menu, then selecting the Magisk zip file you downloaded earlier. This will allow you to root your device and access advanced features.
