Created this post due to a unique problem that has happened twice to two separate remotes (RC) and am wondering if this has happened to anyone else. If not, be forewarned of the potential problem.
I purchased two Mavics, using one and holding the other on the side as a gift to an enthusiast friend. I upgraded firmware on the first Mavic using DJI Go (this was not the last firmware dated 12/6/2016. but the prior version). Used an IPhone 7 plus. The problem apparently resulted because I used the USB Mini port (underside of the RC instead of the USB Micro (side of the result to be used with the grips). I simply hate having to remove my IPhone case to use the side port with the grips, and found it easier just to plug in to the underside port. The upgrade worked, but stalled at 99%. Then received a message that connection was lost. I reconnected the app through the USB Micro and it connected, indicating completion of the upgrade.
Problem is that the USB Mini was then non functional. Tried different cables and different devices. I sent the unit back to DJI in GA, and they repaired under warranty, and am still waiting to receive the RC.
This is what's interesting. I used the second brand new remote, linked it to the Mavic and did the exact same firmware upgrade, using the same USB Mini port. This time used DJI Go 4. The exact same thing happened. Stalled at 99% due to the disconnection. The USB port is dead. Once again, DJI agreed to take back the 2nd remote for repair, but it can't be a coincidence that both RC's failed exactly the same way.
I don't know if the problem is hardware or software related, and the repair notes from the first RC repair apparently weren't helpful to DJI Service. They are obviously going to look at it more carefully this time.
I am wondering if anyone else did the bird's firmware upgrade using the USB Mini port, with IOS, and had no problem. If so, I suspect the Mavic may be causing the issue.
