Encryption key fix (fast cyan blinks with occasional red)

Soon after posting this I fixed my issue by updating my firmware via the instructions here.

Garadget firmware 1.24

The updated firmware 1.24 is out and most units have automatically received the update. The purpose of the update was to update underlying system to the most current stable version. There is no change in any of the functionality from the previous firmware release. In case the manual firmware update is needed, here are the steps: disconnect Garadget from the opener and power remove M4 screw connecting the main enclosure to the mount so it can be taken down without ripping out the adhesive pad…

I still had to put the device in DFU mode, and reboot my computer while it was plugged in. But I got it working again.
