This repository contains the scripts and pre-compiled binaries used to create the rpi-eeprom package which is used to update the Raspberry Pi 4 and Raspberry Pi 5 bootloaders EEPROM images.
Please check the Raspberry Pi general discussion forum if you have a support question.
To reset the bootloader back to factory defaults use Raspberry Pi Imager to write an EEPROM update image to a spare SD card. Select Misc utility images under the Operating System tab.
