Following on from my problems last week with the Mavic Pro not recognising SD cards, & subsequently being unable to refresh the firmware, I have sent it away to one of the UK’s DJI registered maintenance outfits.
I have just heard back from them that the battery is a non-standard (i.e. not from DJI) item, & that this is why the update refresh wouldn’t work.
Quite apart from the fact that this means that the SOB who sold me the drone had swapped out the genuine battery for a cheap copy - has anybody else had similar issues using non-standard batteries? Or am I the only person who finds themselves with a non-DJI item on their hands?
