Ubnt-erx Error Updating from 19.07.7 to 21.02.1

Hi, I got the following message when updating, via lucy, from 19.07.7 to 21.02.1 Device ubnt-erx not supported by this image Supported devices: ubnt,edgerouter-x ubnt-erx ubiquiti,edgerouterx - Image version mismatch: image 1.1, device 1.0. Please wipe config during upgrade (force required) or reinstall. Reason: Config cannot be migrated from swconfig to DSA Image check failed. The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for …

Though, if I were you, I'd hold off the 30 seconds reset 'trick' til I've heard back from the experts here. You might be past that point.

Also, by default in OpenWrt, eth0 is the wan port. I usually connect to eth1 to ssh in or access Luci.
