I searched the forum but didn't see this discussed already so forgive me if it has already been addressed..... I just purchased an Inspire 1 and before I started flying I updated the firmware per the instructional videos and everything went fine with one exception. I updated the firmware in the following order 1) Inpsire 1 with a TB48 battery (TB48 #1) installed - attempt update - success 2) Replaced TB48 #1 with TB48 #2 - attempt update - success 3) Replaced TB48 #2 with TB48 #3 - attempt update - success 4) Replaced TB48 #3 with TB47 #1 (the one that came "in the box") - attempt update - as soon as I turned on the battery to initiate the firmware update on TB47 #1, the gimbal/camera started shaking and turning erractically so I turned it back off. 5) Removed TB47 #1 and replaced with TB48 #1 6) Connected Remote Controller #1 (the one "in the box") - attempt update - success 7) Connected Remote Controller #2 - attempt update - success So with the same .BIN file I was able to update everything but the one TB47 that came in the box. I don't dare try again because I am worried about damage to the gimbal. Could anyone shed some light on what is going on and how I might fix it?
