For those who are having issues with the update, this solution is working for eveybody tried. I took me 2 hours to find out the processMake sure you have at least 50% battery

1- Reset the smart controller erasing all data
2- Do not connect it to WiFi
3- Go to settings, Display , Sleep and change to NEVER
4- Download the DJI Assistance 2 for Mavic here is the link. https://www.dji.com/downloads/softwares/assistant-dji-2-for-mavic?pbc=mF6h4ZTt
5- First open the DJI Assistance and then plug the USB C cable to the smart controller ON.
6- When the control ask for the USB configuration select CHARGING
7- Start the update to the last firmware.
8- The update will have 3 steps: Download, Transfer and Install the update. When installing will hangfor few minutes in 16% and 98% (is normal, just wait)
9- If everything goes fine at 98% the controller will reboot by it self and once boot you will see a DJI logo with a progress bar installing. Will reboot 3 times installing this update. This will take few minutes.
10- Once the controller boot again you should be ready to start Pairing the drone.
11- To pair the drone, go to Settings, Aircraft Management and Add the new drone
12- when the wizard indicate and stat beeping to pair the aircraft with the Mavic Air 2 on hold the power bottom for 4 seconds and will start paring.
13- this should complete the process.

Note: if you turn on the WIFI for any reason, the firmware will try to download automatically and will fill the memory and you will have the memory full error. You will have to Reset to factory and try again.

Thank you it finally worked after 2 tries. Quick question I have been really frustrated with the controller since acquiring it on September 12 as it keeps on giving me a NFZ cannot take off although I'm not in an NFZ zone. What can I do to fix that, especially my regular controller is working well. I'm flying the MP2

At that point is my understanding will be contact DJI for assistance.
Have you try with another software like Litchi or Dronelink insted the DJI 4 Go ?

Make sure your DJI 4G has the last version. You should have it with the new firmware.

Remove the SD card and start over. When you Reset to factory settings you should have sufficient space to follow the steps. Do not connect the smart controller to the WiFi after reset to factory.

Are you changing the Display Sleep mode to Never?
Do you have at least 50% battery charged?

If this solution is working for everybody tried, should be in the sticky top area to avoid people keep creating multiples thread for the same issue.

Hey all,

Stumbled on this thread this morning while fruitlessly trying to get my smart controller up to 01.01.0040 - over, and over, and over.  I followed the steps in the original post and kept running into a condition where it would download to 99% and freeze, or (much less often) immediately say "upload failed."  I'd already done the reset, twice, and it still wouldn't take the update.  

So finally from sheer frustration I connected to wifi on the controller and attempted an upgrade - it kicked me to the DJI login, and after I authenticated, it identified the 01.01.0040 update.  I went ahead with the wifi-based update and it was successful (with the same hangs at 16% and 98%, fwiw.)  Hope this helps somebody else... though it does seem every time I update this thing, I have to follow a different process.  It's weird too, because the Mavic Assistant handles the drones themselves just fine!

Thanks for the informative post.  I keep getting "Network Error Please Retry"  When attempting to connect the device in Assistant 2 for Mavic.  Any thoughts on remedy for this problem?

It's crazy that this firmware updating (stuck at 99%) is still unfixed after so many months (if not years, from what I've seen when I searched this issue).  Your procedure worked for me so thanks!

This is excellent information....I realize this is an old thread, but this just helped me with my issue.  The biggest problem I was having is that my controller was shutting off and I didn't realize it...so when it got to the point to actually install the firmware, it was OFF and caused an issue.

So, to me, the biggest item in the procedure above that fixed my issue was:
3- Go to settings, Display , Sleep and change to NEVER

You never want the controller to go to sleep during the upgrade process....my internet is OK, but not the fastest and it was taking a long time to actually download the firmware before it even attempted to update the controller and the controller was going to sleep on me during this long download waiting period.

Props for posting these instructions!

Sounds great, guess to use it for the Mini2 you would just have to choose it before starting this procedure?
