equipment is restarting in loop
does not recognize in netinstall, does not recognize the ethernet cable in the boot port
the message is displayed
*RouberBoot Booter 3.41*
*Loading kernel.. Kernel not found or data is Corrupted*

Your device are hacked (or you hacked the device) near for sure...

3.41 = no bugfix at all = something stole your routerboard
no press key request = protected routerboot enabled = no netinstall if you do not know the exact timing

etc.
