Issues with Xiaomi Gateway (lumi.gateway.v3)

I have been unable to get HA to recognize the hub - almost certainly because I let the firmware update right when I powered it up. There is a long thread here, which I’ve read thru - but wondered if anyone here knew if its possible to reset it to factory settings (ie go back to the firmware it came shipped with) and redo the set up, and skip the FW update this time around?

Would Method #2 in this write up nix the firmware update I did?
