"Fatal: Target device '/dev/dreambox-rootfs' is not writable"

with the serial connected (in recovery mode) I destroyed the GPT partition with the command "sgdisk -Z /dev/mmcblk0"

I rebooted with the reboot command, I held down the power button to access the recovery menu, once the recovery started I started the online restoration, after a few minutes I restarted correctly.
