  • OAK4-D PRO no lights after OS update

    Hello,

    I tried updating the OS on the camera using the commands on the docs but it does not have any lights anymore, it does not even show up in adb devices. Is there any other way to connect to it and factory reset it?

      Which host OS is this? No light generally means that device doesn't have enough power / is not booting. I'll check with the team to troubleshoot.

      Which method was used to update the OS?

      Thanks,

          Window's host OS. It is not a power issue because I have been using the same USB-C power brick as before when it was fine. Even tried to plug it into a Poe+ switch with enough wattage and still does not have any lights at all.

          Ran the following commands:

          I had downloaded the appropriate zip file and moved it to the data directory

          recovery --wipe_cache --update_package=/data/full_update_luxonis_ext4.zip

          reboot

              Which OS was installed before that?
              I suggest you try accessing the device via fastboot. It should already be installed when you install ADB.

              1. Plug in USB-C from your PC to the device.

              2. Press and hold the reset button on the back of the device between the M8 and M12 connector. You will need a toothpick or something similar.

              3. Plug the power (POE).

              4. Release the button.

              5. fastboot devices should list a connected device.

              Let me know if you can find the device.

              Thanks,

                    It had the original OS from the factory before that (1.1)

                    I followed the steps you listed and was still not able to see the device using the fastboot command. There are still no lights. I tried from 2 machines Windows and Linux and had no luck in getting the device to show up

                        Can you write to support@luxonis.com we'll have the device replaced. It is most likely a SW brick and if you can't access it even under fastboot, then it's best our factory re-flashes it.

                        Thanks,
