I had 5.x on ROS 112 but performance had been horrible, so I decided to downgrade to 3.30
The downgrade went ok and when booting I hear the single and then double beep of normal booting. The blue light comes on as usual. However the router is non-responsive via ethernet and wifi. I cannot put it into recovery (netinstall) mode with the S1 button or S-RESET jumper. How do I proceed to reinstall 3:30? How do I get it to do a netinstall?
On another note, it is a long standing problem of mine that ROS devices can be put into recovery mode very problematically. Last time I spent several days with a 751 to get it to boot after a failed flash.
