I programmed the NRF9160 Feather via NRF Connect and JTAG (using Erase and Write). This erased the boot loader and broke the USB update process. I downloaded v2 of the boot loader and flashed using nrfjprog – but it would not bootload. I tried v1 of the boot loader, and it almost works – when I upload via newtmgr, it stops at 96% and gives me Error: 3. What am I doing wrong?

    NAshworth2 hmm, download and flash the attached.

    Here’s the commands

    nrfjprog --program <hex name>.hex --chiperase
    nrfjprog -r

    That should get you back to where you need to be.

      jaredwolff When I click on the download button, I get a popup stating “You are not allowed to download files”. I checked my browser security settings, and I don’t think it’s on my end.

        jaredwolff Thanks - not sure what the issue was as I was logged in. I was able to download and successfully reflash the device, and boot loading is now working.
