I'm sad and happy to hear that. Sad that your not able to record these valuable files like everyone else is able to do, but happy to hear from you and that I'm not alone in the world with this problem.
Up to now, it seemed everyone with a
Mavic 2 (Pro or Zoom) were able to record those FLYxxx.DAT files as well as the text files.
I just checked the build date and mine was built on 18 December 2018.
You tried some things that I had not tried, that being step backwards in the firmware updates looking for a point that the files may be written and then they stop being written. Reason I did not try this is that 2 of the experts here on the forum were able to record and review the FLYxxx.DAT files and we were all running the same firmware/updates from the AC to the Controller to the iPad.
I've been working closely with DJI trying to resolve this issue with not being able to recording these files but the proper folder (MCDatFlightRecords) being created.
If you are able to figure out what is going on Please PLEASE share how you were able to resolve the problem.
I'm thinking there are a lot of folks out there with this same issue but they have been flying and have not needed to come to this forum asking flight related questions. They don't realize these files are not being recorded. Most probably don't know this information is even being recorded (or supposed to be recorded). The aircraft and remote controller appear to operate normally either way.
I hope to have some updated information soon that I plan to post here.
