I found this completely by accident. I happened to accidentally re-applied the 01.02.0015 firmware and had to rollback.
But after the rollback - I was curious what that “Unlock Geo Zone” was in the DJI Fly app. I figured without an internet connection the DJI Fly app couldn’t force a lock onto the drone.
- Put your device into airplane mode (Disable Wifi, Cellular & Bluetooth)
- Start the DJI Fly app.
- Clear cache (I’m not 100% sure this is needed - I did it to play double/triple safe before connecting)
- Profile > Settings > Clear cache
- Power on Goggles & Drone
- Connect device (phone/tablet in airplane mode) to Goggles. The DJI Fly app, will not force an update.
- On DJI Fly app
- Profile > Settings > Unlock Geo Zone > Aircraft unlocking Licenses
There you will see the Drone-Hacks hack applied.
