I've had my P2 since the beginning of January '14 and never had any problems with it. I've been on firmware version 1.8 and had well over 100 successful flights with the P2 and Zenmuse H3-2D gimbal. I received my H3-3D gimbal today and installed it. Fired up the Phantom (still on 1.8 firmware) and both the Phantom and the H33D seemed perfect. I decided to upgrade my firmware anyway, and now my gimbal is bricked and the Quad is also bricked when attempting to use firmware 3.4. As soon as I update to 3.4 I get error message popups as seen in the pics. The quad does not respond to the remote nor does it flash its LEDs when updated to 3.4. I was able to downgrade back to version 1.8 and the quad functions properly, however, the gimbal remains bricked on all firmware versions. The Gimbal ICU seems to have no firmware. Attempting to upgrade its firmware causes a crash. The Gimbal has power and just hangs there. I've tried the jumper trick to reset as seen in other threads but nothing seems to happen. I'm not sure if this is possibly because my main controller needs to be on a newer firmware for this reset trick to work. I'm completely lost now and very frustrated. Any advice would be much appreciated.
