Hello I would like to share this information because I saw in many publications doubts about the correct flashing of the LiteBeamM5 in my case the XW. The only possible way to get the antenna up and running with OpenWRT was with the TFTP method directly regardless of the Ubiquiti firmware installed, I did several tests where it jumped from OpenWRT to Ubiquiti and vice versa without any problems. Many people had the problem that when they tried to access Luci the page did not appear and gave them an error in the browser. But this is a simple problem to solve since instead of writing directly 192.168.1.1.1 in the search bar we must write http://192.168.1.1/cgi-bin/luci/ and in this way the OpenWRT opens directly without any problem. I hope it will be of help to someone and that I can be understood as my English is not the best.
