Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.

 I am trying to program an nRF9160 using a Segger Flasher Compact with J-Link version 7.60e and nrfjprog version 10.15.2 on a machine running 64-bit Windows 10. This was working for a few days but stopped working this morning although nothing changed. I have read through the forum about other people experiencing the same issue and tried all of the fixes suggested. I uninstalled and reinstalled both JLink and the nRF Command Line tools to the latest version. I have tried both the 64-bit and 32-bit versions of these with no success. 

The flasher does appear under device manager: 

Running nrfjprog --com I can see the Flasher:

Can someone please tell me why it is appearing as an unsupported device in nRF Connect for desktop and failing with the command line tools?

Hi Katelyn,

We are getting a few reports on the device not being detected. Our developers are currently working on a fix for this. In the meantime, could you try downgrading to v3.7 of the nRF Connect for Desktop and try once again.? Please follow the steps mentioned below to do this.

1. Download the latest 3.7 version of nRF Connect for Desktop from https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-desktop/Download?lang=en#infotabs (for macOS this is 3.7.2, for Windows and Linux 3.7.1 because 3.7.2 was not needed and not released for these)

2. After starting nRF Connect for Desktop 3.7, a prompt will come up about the upgarde. Click "No" on this.

3. In the settings, click on "Add source" and enter the URL http://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.7-apps/apps.json

4. Back in the list of all apps, all apps should show up twice now, one with "official" below them and one with "3.7 compatible apps" below them. If you want to hide the incompatible versions, click on "Filter" and deselect "Official".

5. Install the apps you need in the older versions and use them.

Hope this helps. Please try and let me know if the device is detected when using v3.7. 

Kind Regards,

Swathy

Hi Swathy,

Thank you for your reply. I tried the above steps and unfortunately the device is still not recognized in nRF Connect v3.7.
