I have an Onlykey running one of the newer/signed firmwares. I mostly use it on Windows 10 with the OnlyKey app.
It was behaving well, but I needed it for a different project, so I used the “wrong password 10 times” to wipe it.
After wiping it, however, the Onlykey app does not detect it.
I tried shorting the two corner contacts, and after I do that, my linux system does at least show the device as connected.
Once I shorted the two corner pins, I was able to write a firmware using the teensy_loader_cli from linux. I tried beta7, as that was the latest that seemed to have a HEX file included.
However, after loading that, the key remains unseen by Windows, and linux doesn’t seem to like it either.
I don’t get any lights on the Onlykey when I plug it in.
I can re-do the corner-pad-shorting and re-program it, but if I remember correctly, the bootloader on the device was updated by one of the later firmwares to care about firmware signing, so I’m not sure how to get a signed HEX-format file, or if there’s something else I should be doing instead?
Thanks for your help!,
