Hello, I have the Phantom, with the Upgrade kit, the Zenmuse H3 2d, in a first time it's work nice without flying yet. After plug it to the Dji soft, an update to the 3.14 version, i have the GCU Hardware ID like this: "?????????" and i make a lot of reset, back to 3.12 firmware, 3.14, 3.16 and nothing! Did some of you know how to hard reset the updrage kit or the GCU on it ? Thank you.
