The [Raspberry Pi Imager](https://www.raspberrypi.org/downloads/) provides GUI for creating a GUI to update the bootloader and configure the default boot-mode.
|
To reset the bootloader back to factory defaults use [Raspberry Pi Imager](https://www.raspberrypi.org/downloads/) to write an EEPROM update image to a spare SD card. Select `Misc utility images` under the `Operating System` tab.
