At first update of firmware and App. Then i'd massive problems. Therefore the trial to rollback to older version via SD.
After then no longer connection between drone and RC. No longer possibility to use update via SD.
@Dendy: I did it the same way. After then i got no connection beetwen drone an RC.
Autel service told me after an inspection, that core is damaged and has to exchanged for 550 eur.
I want to replace the core board of my nano plus, because its damaged after an update.
Can someone tell me, how to open the aircraft after loosening the screws?
Special points to lever with a screw drive?
Where can i buy such a core board?
