Just to note: I tried update / full-upgrade with a running 6.7.1 installation which loads by that a new eeprom image. But it turns out then that rpi-eeprom-update -a does not burn the new bootloader. After reboot
rpi-eeprom-update still shows the old version and that a new version is available.
I then followed a similar approach as @DRONE7, but used instead the Raspberry Pi Imager on my PC with Linux:

I then followed a similar approach as @DRONE7, but used instead the Raspberry Pi Imager on my PC with Linux:
- With a spare microSDCard plugged to the PC launch Raspberry Pi Imager
- Then select CHOOSE OS > Misc Utilities Images > Raspberry Pi 4 EEPROM boot recovery.
- Select SD Card > Generic STORAGE DEVICE ....
- WRITE
- Remove the microSDCard safely
- Insert it in the Raspi and boot
- After a while the green led starts blinking fast signalling success. (An attached HDMI display should turn green at success or red at failure, but I had none.)
- Power off and remove the microSDCard.
