Great to hear that you got it to work on Windows!

We will continue working on making the process easier, and figuring out why it does not work as it should on Linux.

Updating to 3.6.1/1.4.8 seems to make to work, I was able to update modem firmware on Windows 10.

I was not able to update on Linux.

Hi, and please accept my sincere appology for the late reply.

I have been trying to figure out what the issue could be, but have unfortuately not been able to find a good soultion yet.

First, could you make sure that you are using the newest versions of nRF Connect for Desktop (3.6.1), and the Programmer application (1.4.8).

Also, some other customers who have reported problems were able to solve them by using WIndows 10, so let's stick to that for now.

If you are using the newest versions, does that help?

Secondly, just to be sure:

When you are putting the nRF9160 in MCUBoot mode, are you powering the Thingy off with the power switch, and holding SW3 (the "main" button in the middle of the PCB) while powering the Thingy on?

Does the Thingy appear in the device manager?

Does it appear as a storage device?

Are you able to update the application on the nRF9160?

Do you have any external programmers you can use, such as an nRF9160DK?

I have updated the connectivity_bridge, but still I receive the same error message.

[quote user="torhans"]How about the dip-switch, should it be in nRF91 or nRF52 position?[/quote]

That does not matter when doing DFU.

The switch controls the routing of the 10-pin header used when programming the Thingy:91 with a programmer.

[quote user="torhans"] I assume that "thingy91_nrf52*" files are for nRF52840[/quote]

Yes.

[quote user="torhans"]I have to push SW4 during start-up[/quote]

Yes, when updating the 52. FOr the 91, you must use SW3 (the "big" button)

As the procedure describes that I have to update the modem, first I never tried .hex nor .bin files using nRF Connect for Desktop.

I tried just now, but got the same error message as above.

There are a few things that are unclear in the mcumgr guide. I assume that "thingy91_nrf52*" files are for nRF52840 and I have to push SW4 during start-up. How about the dip-switch, should it be in nRF91 or nRF52 position?

Hi,

When using the Programmer application in nRF Connect for Desktop, you should use the .hex files, not the .bin files.

What hardware version of the Thingy:91 do you have? Have you updated the firmware on it before, or is it a new device?

Did you hold the (big) button when you powered on the Thingy to set it in bootloader mode?

Also. remember that you have to hold the small button when setting the nRF52840 in bootloader mode.

If you did all the above correctly, could you try to update the nRF52840 to the newest connectivity_bridge version using mcumgr from you Linux computer?

To do so, you can follow this guide: Update Thingy:91 firmware with mcumgr.

Remembder that when using mcumgr, you must use the .bin files.

Best regards,

Didrik
