tried to update.
I downloaded to two different USB fat 32 flash drives. each time, the control box led flashed many different colors, lots of beeping ,but at the end, all i got was a quick flashing blue led,that appears to go on indefinitely.

So I thought i would do a factory reset, but that too just leaves me with the quick flashing blue led.

So what went wrong and how can I fix it now?

Thanks in advance
