XE75Pro Firmware Upgrade
I downloaded the 1.2.10 firmware from the EU website for my 5 x XE75Pro v2 (EU) and attempted to upgrade via the web interface. Having selected the (unpacked) upgrade file and pressed the Upgrade button, the only thing that happens is an "Upgrading" box for 4-5 seconds with no progress bar, and then it immediately reports success. It clearly didn't perform the upgrade, which remained at firmware 1.2.9. I rebooted all the XE75Pros and tried again with the same result.
I can wait until the auto-upgrade becomes available, but I am concerned that, if I ever need to, I won't be able to perform a web upgrade.
