Hi,

I have nRF9160 DK. I want to update firmware to  (From Your WebSite: Link Pasted)

    nRF9160 LTE-M/NB-IoT/GPS Modem firmware

https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160/Download#infotabs

The nRFConnect 3.0.0 Shows nRF52840 device, instead of nRF9160.

I tried installing pip install nrf9160_mdm_dfu

Downesn't work.I also tried to download through Segger Embedded Studio. Nothing is working.

Please point to me a valid resource document with steps or instructions for updating the above mentioned firmware.

Thank you very much for your support!

Hi,

You should be able to update the modem FW through the Programmer app in nRF connect. Suggest you update to the latest version of nRF connect (3.2.0 at the time of writing) and make sure the programmer app is up to date as well. Then launch the app, select your device from the drop-down menu in the top left corner, and click "Update modem" button. 

If this doesn't work, try erasing the chip with nrfjprog first: nrfjprog -e/--erase. Hope this helps.
