Hi All, I'm new to the forum living in Singapore. I've had my Mavic Pro since Nov 2017 but did'nt fly much. Recently tried to fly again after some time, but could'nt because the place where live is in the NFZ. Never had this issue before. When I checked the NFZ in Singapore, almost the entire Country is a NFZ. Determined to fly again, I read about the MOD which is available i.e. downgrading to 03.700 using Dumbledore and making changes to Parameters using DJI assistant 2. I did all the downgrade and parameter fixes without any issues. But now facing with Main Controller Error : i.e Data recording error and Data Logger error. I've searched everywhere but to no avail. Appreciate help. Many Thanks.
