Note on Altitude Unlock

Altitude/distance/NFZ unlock is not possible via DUMPL commands alone. The 120m CE altitude limit is enforced by the DJI Fly app via a C0 class runtime flag that overrides flight controller parameters on every connection. No FCC unlock app can bypass this — it requires modifying the DJI Fly app itself or flashing patched firmware. The flight controller parameters are set correctly in the profile, but the DJI Fly app overrides them. There is no known workaround without modifying the DJI Fly app or flashing patched firmware.
