I just plugged in a keypad for the first time on my GC and it came on and said "firmware update, please wait". It then shut off and never came back on. I did this for 3 keypads and they all acted the same. Any ideas....I tried to unplug everything hoping for a reset, but still nothing.
Firmware was 2.06 when it lit up, so I guess it was upgrading to 2.10.
