R650 Showing not supported in Unleashed UI

[edison_zhang]

I have a Ruckus R650 in my network,after default configuration the R650 status shows not supported，and the current firmware version is 200.8.10.3.278，but I can't find the corresponding version（200.8.10.3.278） on the official website for R650，now I can't upgrade firmware version，suggested that the upgrade needs the same version，but on the official website only find firmware version is 200.9.10.4.202,and I don't know what I need to do, and can not seem to get any assistance at all.
