        Hi, @modaltb I tried with it, but still have not succeeded 😐

        terminal logs.JPG

        Two things I want to confirm

        1. Am I using the right system image? I am using VOXL Platform Release 3-3-0 0.4.6 b downloaded from https://developer.modalai.com/asset

        2. The cable, in the video I can see the cable like below cable in video.JPG
          But I am using the cable, MicrosoftTeams-image (3).png

        Is this cable will work? or do I need the same cable shown in the video? please let me know if am doing something wrong here.

          Hi @Gaurav-Borade ,

          You are correct, the USB cable you have is fine and the image is also OK.

          Question: are you using an Ubuntu VM on another host machine? This is something I'm not positive about, should be OK but just not something we've tested too much.

            @modaltb Thank you for the confirmation on the USB cable.
            Yes, I am using Ubuntu Virtual Box. The board was communicating fine with the Virtual Box previously (Before bricked) so unbricking on that only. I will try it on another machine as well.

              @tom Hi, I'm the op of this post (link) but thought I would ask my question here since it seems to belong here now.

              Screenshot from 2022-02-08 21-32-16.png

              I am following the Unbricking VOXL instruction. More specifically, here's what I'm doing.

              • Before anything is plugged in, I left the FASTBOOT switch on and the Debug board is already attached.
              • Plug in the (1) cable for power
              • Plug in cable (3) -- just a micro-usb
              • Wait 5 sec, turn off the FASTBOOT switch.
              • sudo fastboot devices
                And this returns nothing. I've also tried adding cable (2) right after I plug in power which didn't work (I've tried many things..)
                Please advise if I'm doing anything wrong. Thank you!

              Jae

                @Jae-Park if you do a watch fastboot devices do you ever see it come up? Another thing to check, what is your output of lsusb after about 30 seconds of having the Voxl-flight powered up and plugged in to your pc?

                Also cable “2” is unrelated to this process

                  Here is the output from lsusb. (once before attaching the power&micro-usb and again but 30 seconds after attaching them)
                  Also, I retried it again, following the exact steps I had described above, while watching on watch -n 1 fastboot devices. And, nothing had showed up.

                    @Jae-Park Can you do the same lsusb test without the debug board attached?

                      This is after attaching cable (1) and (3), in the order, and running lsusb (waited some time before running the command).

                        @Jae-Park It appears to me as though the VOXL portion of your VOXL-Flight is in a "bricked" state that is not fixable without sending it in for inspection. Refer to this RMA page for more info: https://modalai.com/rma

                            @tom Would it be going in for RMA PCB or Drone? It seems like PCB is what I'd want to choose.
                            Also, if that is the case, can I ship out just the board, or would it have to be the entire drone itself? Thank you.

                              @Jae-Park You should ship out the entire drone so that the team can verify that all of the components are functional, fix anything else that you may not have seen, and do a final flight test before sending back.
