Good day

I am attempting to do the latest updates on my thingy91 device.  I have followed the steps as state here:

The first part works fine I able to select MCUboot and update the connectivity bridge successfully.  After attempting to update the modem firmware I get this error:

 I get the same error when doing the next step.  Does anybody know how to avoid this error?

I've attempted to use the previous and the latest modem firmware with no luck.

Hi

Are you holding down SW3 while switching on the Thingy?

Best regards,

Good day

Yes I did. I am in the correct mode as you can see in the screenshot. Thingy91 is being selected on the top left

I have seen similar behavior when someone rebooted the Thingy by plugging the USB cable in and out.

Are you doing this, or are you using the on-off switch?
