      I have a VOXL2 board that was previously working fine. Today, while using the ADB shell in WSL, I discovered I could not connect to it, but I was able to connect using an Ubuntu computer. After connecting, I configured a WiFi dongle and used SCP to upload about 2GB of files to the board. After a while, I noticed the SCP command had not completed, and later attempts to connect via SSH also failed. At this time, the light on the WiFi dongle was flashing slowly instead of blinking rapidly as it does when connected.

      I tried power cycling, but the light on the WiFi dongle remained abnormal. I also tried changing the addon board and the WiFi dongle, but only once did I see the light on the WiFi dongle flicker (though it still didn't connect); after that, the light on the WiFi dongle did not come on again. I also attempted to use the ADB shell, but the device could not be found.

      I followed the unbricking instructions to try flashing, but it failed halfway through. Below is the execution message.

          Here are the situations without connecting to VOXL2:
          36fee44c-da28-46e0-8cdc-add36b502d9f-none_lsusb.png

          Here is the situation with VOXL2 connected and running normally:
          b7f81fb8-9e78-4858-9fb0-5d7571dff9c3-normal_lsusb.png

          Here is the situation with VOXL2 connected but encountering issues:
          bc8efda6-d1b0-42d7-9519-15dff20f4e82-error_lsusb.png

          When I slide the SW2 switch into the OFF position, it remains in the QDL mode and I am unable to connect via adb. Is there any way to solve this issue?

            @rogerli That 2nd screenshot shows booting correctly into ADB mode (901d). Are you able to ADB on when that is the case?

              The 2nd screenshot is another VOXL2 board.

                @anghung For the non-working VOXL 2 , can you determine whether it has a QRB5165 or a QSM8250? https://docs.modalai.com/m0054-versions/#m0054-1-and-m0054-2

                    @anghung Okay I would retry flashing using QDL. If you still have issue you can submit an RMA and we can fix it for you: https://www.modalai.com/pages/rma
