Came across an odd one today while updating the software on our two Eoses - wondered if anyone had encountered anything similar before.
One of the consoles updated without any problems. The other Eos seemed to update OK, but when it booted after the update had completed, there was no response from any of the buttons to the right of the right-hand touchscreen (Displays / Snapshots / Macro / More SK). The LEDs in the buttons flashed during boot, but the keys did absolutely zilch when pressed. Rebooted the console, and it was still the same story - no response from any of that cluster of buttons. The only way I could get them to work again was to uninstall the software, roll back to the previous build, and then run the update again - following which all was well.
Weird!
