    @Mohammad-Saeid-Anwar It looks as though your RB5 is booting into fastboot.

    I would recommend flashing our latest platform release (0.9) which can be found here: https://developer.modalai.com/asset/view/117

    following the steps outlined here: https://docs.modalai.com/Qualcomm-Flight-RB5-voxl-sdk-upgrade-guide/

      @tom I have a little confusion here. As I said earlier, the ADB shell has not been working. So how can I install your specified system image using the ADB pull command?
      like these commands:
      adb pull /data/modalai/opencv_tracking_intrinsics.yml
      adb pull /data/modalai/opencv_stereo_intrinsics.yml
      adb pull /data/modalai/opencv_stereo_rear_intrinsics.yml
      adb pull /data/modalai/opencv_stereo_extrinsics.yml
      adb pull /data/modalai/opencv_stereo_rear_extrinsics.yml

        Those adb pull commands are backing up config files on the drone, if it's only accessible through fastboot you'll have to skip those steps and reflash the drone. By default the data partition on the board is not reflashed, so as long as that partition wasn't corrupted the data will still be there.

          @Mohammad-Saeid-Anwar If you end up flashing and the cam cal files are still missing we can likely provide you with them on request as we back them up before shipping out a drone.

            I tried to flash your latest platform release (0.9). But I have faced the same issue. No ADB shell connection. Please take a look.

                @Mohammad-Saeid-Anwar It seems your device is stuck in fastboot mode so don't worry about trying to pull off the cam cal files. What happens when you run the platform release install script?

                    @Mohammad-Saeid-Anwar Can you run the following commands on your host PC back to back and post the output here:

                    lsusb
                    adb devices
                    fastboot devices

                        @Mohammad-Saeid-Anwar Hmm try the following:

                        adb kill-server
                        adb start-server
                        adb devices

                            @Mohammad-Saeid-Anwar Do you have any other VOXLs that you are able to connect to via. ADB in order to determine that ADB was configured properly on your machine?

                              No. I don't have any other voxl.
                              Yes, it's properly installed. I had previously worked with the same ADB installation. Suddenly, it stopped responding. I also tried with two other machines with proper ADB installations. It showed the same problem (no device found).
