What could be the reason for the constant rebooting of the above DEVICE?
The log you provided does not help. They are all recovery boot log.
We need you to provide the full log “before” recovery boot happened. Recovery boot image is a template initrd provided by us. Everyone’s recovery image is same so no need to check…
