R310 Unleashed unable to upgrade from v200.7.10.102.64

[rafe_oxley]

R310 running 200.7.10.102.64, installed via online upgrade.

APs appear to be working OK, but unable to upgrade. 

Able to remotely connect to dashboard, but under "Admin and Services" options can be actioned but are not processed, including upgrade ability.

I have tried various browsers, disabled any LAN firewall drop rules.

"restore factory settings" appears to work, and rebuild, but does not actually reset the AP.

On remote SSH access to AP, username and password accepted but then SSH session closes.

I have not been able to try a physical reset, not convinced even that would work.

Any ideas? Is there a flash on boot type process?

@rafe_oxley glad to know upgrade fixed the issue.
