I have 2 unleashed R710 and
Registration button and upgrade button greyed out.
no firmware version showing.
only hard reset works. Does not fix any isues.
Doubt these are all hardware issues but maybe.
Can you open the Unleash interface on Firefox and Internet explorer to see if the tab is available on these browser if not done yet ? Additionally what is the current software on the devices ?
The software version is greyed out (blank) as is all functions on the upgrade page. Will try different browsers.
Please keep us posted on how it went with firefox and IE browser and if it works what was the version running.
