Stuck in Firmware Update mode

And please follow this link to fix it:

It literally posted the message when I tried to charge it. I only saw it the next day. It didn’t make any sense since it was not connected to any computer. Just to a regular charging cable.

Best,

Thank you for the information. After verification, we found that holding here while plugging in the USB cable puts Halo into firmware update mode.

So please don’t hold this ear when you plug in the USB cable.
