Are you choosing the right device? Check on the device manager to make sure you’re choosing the right COM. Better to take a screenshot of your issue. ---

hello; sorry for the late reply ! here’s some pictures. i’m using cube orange plus, and mission planner is recognizing automatically. flashing any firmware normally, but to connect … no way. ![dis1](https://discuss.cubepilot.org/uploads/default/original/2X/c/cf6e37fed256975f9d49f1c6591771a20e5f78d0.png) ![dis2](https://discuss.cubepilot.org/uploads/default/original/2X/e/effbad15b114db1826acaf60cecc5a8453f3adc1.png) ![dis3](https://discuss.cubepilot.org/uploads/default/original/2X/b/ba851a59cd4e538f7d209ebff22a44ff224818cc.png) ![dis4](https://discuss.cubepilot.org/uploads/default/original/2X/0/0adc3a457f48ff049db1e978cff9ac94647309b8.png) ![dis5](https://discuss.cubepilot.org/uploads/default/original/2X/8/81d668dff43eefd5c61e342d20bfbdf454024398.png) ---

If you are using windows 11 you sometimes need to just reboot your PC/Laptop. ---

hi, i restarted my laptop many times. note that nothing is connected to it yet. i tried 4 new different cables… i saw a tutorial about [secure firmware](https://docs.cubepilot.org/user-guides/autopilot/the-cube-series-firmware-and-connection-troubleshooting/installing-secure-firmware) : i don’t know if this topic is related to what i’m facing… i don’t know what to do, my EFT416P drone project is paused for now. ![20240313_121706](https://discuss.cubepilot.org/uploads/default/original/2X/5/5aee8604e30d4ed0cce873e6db3acc02cf37fea4.jpeg) ---
