This solved it! Thankyou!
For others, the exact steps I took are:
- I PMd DJI Natalia the email associated with my DJI account, and she marked my account to make the 350 firmware visible.
- I started DJI Assistant 2 on my laptop, plugged the drone in via the DJI USB cable, started the drone
- I waited for it to appear as the visible device, then selected it.
- It listed all the firmware; my current is 550, and the lowest available is now 350.
- I selected 350, hit downgrade
- A few minutes later it announced success.
- I then unplugged the Mavic and plugged in the RC, and did steps 3-5 for the RC
- The RC reported failure to downgrade; it listed 550 as the current still. I ignored this, since the RC never had a problem to update anyway.
- I then left the RC connected, backed out to the start screen in DJI Assistant, and turned on the Mavic and let it connect
- I then hit the device button, and waited for it to load the list of firmware
- I hit the record-video button on the remote
- I told DJI Assistant to upgrade to 700
- About 15 minutes later it announced success
