For those who are stock in 99% with no space available error, the only solution i found was:
1- reset everything to factory deleting all data
2- Do NOT connect the WIFI because the
smart controller will try to download the large update and will fill the memory again.
3- use DJI Assistance for
Mavic 2 to perform the update.
4- Even with this, I had to keep tapping the
Smart Controller Screen every 1 or 2 minutes, other wise will go in sleep mode and you have to start over.
5- In order to bind the
Mavic Air 2 after the update you need to add
MA2 in Aircraft Management, wait until ask for be pair and with the
MA2 on hold the power bottom for about 4 seconds and will pair without issues.
I learn this after 2 hours trying to update until finally I got it. You don't have to remove the SD card. It works for me fine.
I flew 3 batteries already and seen to be everything in perfect order with the firmware and how the aircraft perform. I notice has the same range than the original controller so is time for me to install the Allientech Duo II in the
Smart Controller. Is sitting in my chair
