Spark Rapid Cyan > Green > Red (rinse and repeat)

So the other night my Spark (it’s a spark not a photon) went offline and then started rapidly blinking cyan, then green then 3 red blinks then starts the sequence over again.

I tried factory reset.
I’ve tried giving it the new public key.
I’ve tried manually updating the firmware…

All to o avail.

Any ideas?

Ok… now it’s started just rapidly blinking cyan, and sometimes blinking orange.

I’ve tried resetting the key, and updating the firmware multiple times. Nothing.

How did you do that?
