please make a new devzone ticket and include the screenshots and output log of your process.
Also make sure that you are using the latest SW when testing this.

Hey I am also getting the same error. Did you get rid of this?

If yes, can you please share the solution?

Just an update on this. I was actually trying to do this via a VirtualBox VM (Windows 10 guest).

I had an old Windows 10 laptop, and installed nrfConnect + Programmer, and firmware update works fine.

Reason I was using VM was because I couldn't get nrfConnect Programmer to work via Ubuntu.

Anyway, for now all is good as I have updated modem firmware. Now to see if I can get it online.

Hi, yes I followed these instructions. I'm reasonably certain that it is in MCU boot because the RGB LED does not flash (as it does with a regular power on). Also, after this error is displayed, the board appears to revert back to regular operation (i.e. LED begins usual flashing sequence).

Hi,
Could you verify that you do all the steps mentioned in the documentation?
That it is in MCUboot etc.
