BlockBoy Flasher

The flasher detects your device automatically, so you can't flash the wrong version.


                

Instructions

  • Connect with a USB-A to USB-C cable
  • Turn the BlockBoy on
  • Click "Connect device" and pick the port in the popup
  • Your device is detected automatically
  • Confirm, then wait ~1-2 minutes

Important

The firmware is overwritten. ROMs and saves on the microSD card are not affected.

USB-C to USB-C cables are not supported. Use a USB-A to USB-C cable.

Tools

Only needed for testing or troubleshooting. A normal install does not need this.

Recovery skips the confirm step and re-flashes a stuck or restarting device the moment it is caught — no need to be quick. It uses the firmware selected above and still verifies the hardware first.

Flash your own .img file. The device is still detected, and a file larger than the chip is refused so it can't brick the device.
