@Nathan-Raras That's fantastic! Thank you. I will try it tomorrow when I'm back in the lab and let you know how it goes.

@Nathan-Raras BTW, the terminal window displays a "500 internal server error"

Thank you for that. You're correct that it unarchived with an extra level of folders. I corrected that and retried the process. This time it ran "flash flat build" for several minutes before returning the failure message. I tried starting from the first step, different cables etc but it failed each time - it runs for 10 minutes or so and then prints the fail message. Is there a log file that gives more information to troubleshoot why it fails?

@Nathan-Raras Thank you for the replay. As I mentioned, that IS where I put the image.

I reinstalled qdl using snap and now it finds the image.

It still does not work though. I get the following error I'm trying to unbrick the older model voxl2 board from a Starling.

I'm sure there is a simple problem here but I can't figure it out.

I am able to provision and flash CDT, but there are no choices for the flat build file in the dropdown. I've tried unzipping the archive in both: /modal-qdl/qdl/qfil_app/modalai and ~/modal-qdl/qdl/qfil_app/modalai. Where is is supposed to go? The log window seems to show that it found them (200 ok).
