cant upgrade firmware

Marc

I had a Thingy91 that I think I bricked in trying to upgrade the firmware. I'm able to see the device in desktop programming, but it says erasing then gets to a 100% screen and fails with serial port closed. I purchased a second and getting the same thing. It is now bricked as well, no flashing LED. I've tried it on two different computers Thanks

    Hi Marc,

    Sorry to hear you are getting halted. Hopefully, we will get the devices up and running again.

    Please go through the these preparations, then continue to "updating the firmware" via the link at the bottom. 

    You might need to update the firmware through an external debug probe. Do you have access to any DK from Nordic, for example nRF9160 DK?

    Let me know where/if you get stuck, and I will get back to you.

    Best regards,

    Håkon
