nRF9160 Trouble upgrading Modem Firmware

GBSingh

Hey Nordic Community ,

I have been trying to get the Modem firmware up and running without success for a few days now (Attempted with 2 different PCs and 2 DK with same results) , I hope someone can help me out.

- I have followed all the steps on the detailed tutorial [https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/getting-started-with-nrf9160-dk]

- However during 'Updating the Modem' step , I am not able to read the NRF9160 on nRFConnect v3.0.0 or Update Modem

- when I try using nrfprog to read using  ' nrfjprog --memrd 0 --n 1024 -f nrf91 '  , I get Error : "JLinkARM DLL reported an error. Try again...."

- Here is my latest version : nrfjprog version: 10.3.0 , JLinkARM.dll version: 6.48b

- I have also tried JlinkARM.dll versions 6.40 , 6.44e , 6.48b , and nrfjprog versions 10.2.1

Thanks and regards,

Gurbir Singh

    Hi Gurbir,

    Please check your device manager:

    As you can see I have two nrf91DKs hooked up to the computer.

    Are there any LEDs blinking on the DK?

    Check with the command 'nrfjprog -v' that you have the correct versions.

    It is important that you use a micro USB cable that actually supports sending data. We have seen that some cables only support power, no data. (Typical charging cable)
