Ok the unthinkable has happened..... I was updating my M210RTK and the battery on the crystal sky died!!! now my remote isn't showing any connection to the drone, and when i plug it into the computer i get nothing!! HELPPPP

When you plug the USB from the drone to the computer to run DJI Assistant (make sure you have the right version) - ensure that the small 3 way switch is in the correct position. As I remember it is the left most position. Definitely not the center one. Could be the right position - read the small lettering. I just don't have the drone here to check.
The switch is located next to the USB port.

The Drone is bricked...... trying to find a way to fix it before sending it back to DJI.

What if you downgrade all systems? I did a reset  on my system to default factory then uppgraded and was back on track.  I hope this help.

An update to this issue would be SUPER......2 weeks later?

Did you send the system in for repair? Or find a solution

I mean, if you were updating w/o a full charge you shouldn't even be using these things.  Also, when you get back up and running make sure you firmware upgrade only through a reliable PC with DJI Assistant 2 for Matrice.
