There are some notes specific to rpi installs, so give it a read if you run HAOS on that platform.
Raspberry Pi 5 users need a bootloader from at least 2025-02-12, otherwise the display output may freeze early during the boot. Update the bootloader before installing this update, using one of the following methods:
- Run
rpi-eeprom-update -a while connected directly to the device (using a display and keyboard), prior to installing the OS update.
- Use Raspberry Pi Imager with a spare SD card to flash a bootloader update image to it.
- Alternatively, if you have an SSH terminal app installed, you can run
ha os boards raspberrypi firmware update over SSH right after updating the OS.
My understanding is that it will off you apply those changes
