  5. Choose to boot your D855 handset into the custom recovery mode you should have installed earlier as part of the prerequisites.
  6. Tap on the ‘Install’ option from the recovery mode menu and browse the SD card for that same SuperSU file you transferred there earlier.
  7. Swipe to confirm you want to install that SuperSU on your G3 device by swiping over that same option that is available on the bottom of your display.
