Hi all, I'm a graduate student who is using a Matrice 100 (m100) for my research with a zenmuse x3. It's been a little while since our drone has been put to use, but my boss recently updated the m100, and now when I start up the drone, remote control, and ipad, dji Go connects to the m100, the zenmuse x3 gimbal spins around, and then the app indicates "No Image Transmission Signal" and gimbal is disconnected. Hopefully relevant error screenshots are attached. So far I've tried the following:

• Deleting the app, resetting ipad, and reinstalling app from this thread https://forum.dji.com/thread-51313-1-1.html
• Formatting the SD card, FAT32
• Starting the drone without an sd card in the zenmuse x3
• Relinking the remote control to the drone
• I am in the process of flashing Firmware Update Package Zenmuse X3 v.1.3.1.00 from this page https://www.dji.com/matrice100/info#downloads following these instructions https://dl.djicdn.com/downloads/dev/Matrice/en/M100_How_to_Update_the_Firmware_en_160304.pdf, but I am not sure if the flashing is working. I put the extracted bin into the root and started the drone and haven't seen or heard any indication it is flashing.
  

Any help or tips would be appreciated. This is my first time working with a drone and I'm trying to scour relevant threads, but I'm seeing little documentation on the m100, maybe because it's not a consumer line product?

Update 1 -- I realize I did not download the most up-to-date firmware. I am now downloading update package v.1.3.1.00 for the x3 and attempting to flash. However, after the last flash ran for ~30 minutes, there were no logs or text files in the sd card, and none in any hidden locations either.

Update 2 -- Still no log output after attempting the second flash. I am wondering if the drone isn't seeing the camera for some reason, but am confused because the camera gimbal moves around upon drone start-up.
