Did it ever work? Do you mean the physical install went "well"?
Have you recalibrated the IMU (as the message suggested) before restarting the drone?
The drone was purchased new a few years ago, then it set for about a year, never crashed or moisture, yes the physical install, got it from China, part matched, I mean its easy enough to replace it again or the board, one thing I discovered is it will fly if I install NLD, controller keeps saying "check app" so I dont want to operate it that way, its just a hobby, nothing professional, hate to trash it with out trying a few options.
This is a mystery I will never understand. I have read many stories of drones that (for whatever reason) had been stored/not flown for some time (months or even a year) that just suddenly (for some reason) no longer fly. It's often a calibration issue (IMU/Compass/etc), but it's baffling none-the-less. If it was software, you'd think that others would have the same problem (assuming you are "up to date"). It's well known that batteries need to be exercised regularly to maintain capacity, but it seems as though the actual drone benefits from regular use (kind of like my vintage Nakamichi cassette deck)!
