Today, after upgrading to 6.41.2 my RB2011iL-RM is in a bootloop. There is no
way of recovering it. Maybe I am doing something wrong. I tried netinstall but
the routerboard does not show up what ever I try.

Any idea's?

Connect your PC to a switch with nothing else except the RB2011 router. Windows sometimes won't bring up the ethernet interface without a link. This most often assists with Netinstall restoration.

Thanks jebz! Adding the switch did it!
