    @CJ What operating system are you running? Are you using a virtual machine? I haven't seen this error before myself

    @tom Hi Tom,
    The OS is ubuntu 22.04 and not on virtual machine.
    It seems like it cannot come out of fastboot mode and waiting for adb connection.

        @tom Pls see the image below. The Google Inc.... (fastboot) is the drone usb.

          @CJ If another QDL flash doesn't solve it, this might require an RMA for us to investigate: https://www.modalai.com/pages/rma

            @tom What will be the likely cause for the drone not getting out of fastboot mode?

                @tom Yes, the QDL is successful.

                And installing the SDK is also successful but it just wait for adb interface to be up, which the usb is still in fastboot mode after power cycle.

                  @CJ This is definitely abnormal which makes me think something hardware / power wise is causing the voxl2 to boot directly to fastboot. Your easiest resolution may be to submit an RMA so that you don't risk damaging your board further taking apart the drone

                    @tom , may I know what is the likely component that might need to replace to resolve this issues as the RMA cost of sending the drone may outweigh the replacement.

                      @ck Can't give you an answer as it would require an inspection from our team

                        Hi,

                        I had the same problem.

                        You can try to transfer to the normal operation (& ADB)
                        by:
                        fastboot continue

                        and disconnect-connect the USB cable in order to enable
                        the USB change to ADB.

                        Erez
