I added the Zenmuse Gimbal and attempted the upgrade as instructed here: http://www.dji.com/dji-released-new-firmware-for-phantom-2-remote-control/ I got no further than step 1 (upgrade RC to V18.104.22.168) A warning came up that said "upgrade failed". The red Power LED on the remote went out and my RC unit was dead. I can not get my PC to recognize my RC. The RC Assistant software does not "see" my Remote either. I reinstalled drivers, etc. It seems to be "BRICKED". I'm not suggesting that anyone stay away from this, but I can't understand why DJI has an upgrade that allows this to happen or at least allow another attempt at the upgrade. I would think the software would have a "Fail Safe" built in so it does not just lock up the unit? I followed the instructions exactly as printed, yet it Failed.
