Downgrade firmware of Ubiquiti Nanobeam AC Gen2 for OpenWRT install


I have two devices of this trademark, Nanobeam AC Gen2 WA and LiteBeam AC Gen2 WA. Both have not support of WPA3 encyrptation. So, i wanna install last OpenWRT for WPA3 support but... cannot downgrade firmware from 8.7.12 to 8.7.0 becuase it's blocked process somehow. How can fix that? Thanks for reply.


You must examine release notes backwards, typically 9.9.X downggrades to 9.9.0 while 9.9.0 to 9.8.0 needs config reset and that is usually described in X.Y.0 release notes only.
