Hi Danny,
If you look in the Contents.txt file you can see the description of each file:

Package contents:
img_app_bl/           Full application images, including bootloader. Updated only via debug probe.
img_fota_dfu_hex/     Application only. Use with nRFConnect for Desktop Programmer application.
img_fota_dfu_bin/     Application only. Binary format. For cloud update, mcumgr.

Please try to flash the application: "nrf9160dk_asset_tracker_ltem_2020-09-23_b6ad40d0.hex"

and then "update modem" and select the "mfwnrf9160121.zip".

Then open LTE Link monitor and press the reset button on the DK to get the bootup sequence in the terminal.

Best regards,

Martin L.

Thank Martin

I did follow the manual. The manual says download the version that is found in the image_full. But this folder dos not exist in the September's version. It did exist in the April' version:

So I used the version that is found in the img_fota_dfu_hex folder.

Surprisingly, the size of these files are much smaller than April's version (~80K).

Hi Danny,
Make sure you are flashing the modem firmware and the application firmware correctly.
Follow the steps given in the documentation: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf91_dk_gsg%2FUG%2Fnrf91_DK_gsg%2Fupdating_firmware.html

We also have this quick guide on Youtube on how this can be done.

Please connect LTE link monitor and disable "automatic request" setting (down right corner) and then reset the nRF91DK so we could get the bootup sequence.

best regards,
Martin L.

Thanks for your quick reply.

I had the version of 22/4/2020 (nrf9160dk_fw_2020-04-29_bc7ade8b)

And it was doing "something" as I wrote in my previous

Now I upgraded to the new version that you sent (23/9/2020), but nothing happens. The AT commands are not responded at all.

Hi Danny,

Have you upgraded the modem FW to the latest? https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160/Download#infotabs

I would also recommend that you use the latest application fw: https://www.nordicsemi.com/Software-and-tools/Development-Kits/nRF9160-DK/Download#infotabs
