  • You have to unlock the bootloader on your handset; here we show you how to do it properly;
  • You’ll need your personal computer, the original USB cable and the USB drivers for your HTC One M8 already installed on the computer;
  • Don’t forget about enabling USB Debugging mode by going to Settings>> Developer options>> and then ticking the USB Debugging checkbox under Debugging section;
