I just installed the v2.5.0 update on Windows (the one where you need to manually download and install due to the new nsis installer)
The software ran up and said it needed to install new firmware on the printer.
Did that, then "Scanning for printers…"
Found the printer, then “Need to install new firmware” again…
and looped around, and around…
I eventually broke it out by closing the UI just when it went into the “Scanning” part of the cycle, ie the firmware had been loaded.
Then power-cycled the printer.
Restarted both, and looks good now.
Perhaps the firmware flashing code isn’t rebooting the printer, so it still reports the old version?
Anyway, something to watch out for.
PS - I spoke too soon! Just tried again (shut down the UI and reopened it), and back to trying to update the firmware again. Looks like a real problem. I’ll leave them both shut down until there is a fix.
