Battery died during update. Now the lights on the board and remote just blink slowly. Unresponsive. I am very new to this so I’m catching up as quickly as possible.
You mean the battery died during an update. This would probably cause a corruption which would need a new esc. And with inboard closing up shop I don’t know where to point you.
This is why phones send that “plug in phone during update” message. Agree with Briman, sorry to say.
