This is cross-posting from forum.dji.com because of the severity of the problem (Editor: please forgive me!)
Last night, I was using the I2, props removed, for about two hours, just familiarizing myself with the Go App 4. Everything was working flawlessly. I took numerous screen captures just to remind me where various icons were.
Today when I fired everything up, the GO 4 app indicated that I had "incompatible firmware" and that I had to upgrade it. I operated the "slider" switch and the firmware upgrade appear to complete correctly, albeit with a puzzling message about disconnecting and reconnecting the data cable (as though I had been using DJI Assistant rather than the Go app).
Therefore, I power cycled the I2, the RC, and the iPad Air.
Note: I do not know which version(s) of firmware were installed where last night (I hadn't got that far), nor do I know what the compulsory firmware update this afternoon installed. There was no indication of version numbers during the update.
The Go 4 app then indicated that the compass needed recalibrating (which didn't seem unreasonable given the firmware upgrade), so I went outside and completed the compass calibration. Just as I was coming back indoors (with the aircraft, RC, and iPad all still powered up, I got the "Mobile device CPU fully loaded. Related performance will be affected." I had it on screen just for long enough to do a screen capture. At which point the display on the iPad turned into a series of vertical colored lines and went black.
Now, no matter what I do, it appears that the iPad Air has been damaged and will not even start up. so I have no option to but to take it to the Apple store to have it repaired (of course, it's out of Applecare by now).
I'm very disturbed to see that DJI's firmware is "over-driving" the iPad so badly that it will destroy itself -- especially because I was using the setup flawlessly last night for two hours. It would suggest that the new firmware -- whatever version it is, has not been adequately tested and is capable of actual destructive behavior. I've searched the forum and can see reference to "Mobile device CPU fully loaded," but I have not been able to find out whether anyone else's iPads have been irreparably damaged. Anyone else had this problem?
I do have a second iPad Air, but I hardly dare connect it for fear it will destroy a second iPad.
Thanks in advance
