I followed the instructions on the first post and it worked on v220.127.116.11. Some corrections to that post:
You can downgrade to v02.06.06.00 from v18.104.22.168. You download the file from DJI's site here: https://www.dji.com/downloads/products/crystalsky and follow their instructions. BUT the root method works on v22.214.171.124 just fine.
Also the full gapps works as well, but don't really need everything there so pico is just fine.
Unfortunately DroneDeploy does not work. The version on the play store says unsupported device. I found an older version and sideloaded it. With the pico gapps it would show the welcome screen, I tap next, then it would get stuck on a white screen. So i flashed the full gapps and now it just crashes right away :/. Also my DJI Pilot app doesn't run, but DJI GO v4 works.
