Received mine a few days ago, from the dronenerds ebay store. I'm new to DJI but not model aviation. It appeared as new (with the new style motors), and I had no trouble flying the craft and taking some test video. I was pleased to find it came with a 16GB card installed, although I didn't see it as included in the listing. After that, I sat down and did some reading here and elsewhere to find the optimal firmware. The DJI Go app said I had the following versions:
App 3.1.5
Version 1.5.30+
Remote 1.8.0
I tried a few FW updates, as far as the most recent available on DJI's site (01.10.0090), but it kept failing. Then I read about the FW update log that was in a hidden folder on the SD card... I don't usually leave hidden files and folders turned on to avoid clutter, so never saw it until I was informed to look.
These are the last few lines shown below, after my attempts to change the firmware. Unless I am misinterpreting the log, it appears the FW installed on mine is 1.11.0010. Which exists virtually nowhere. The timestamps are also wacky.
Can anyone shed some light on this?
