https://devzone.nordicsemi.com/f/nordic-q-a/101227/pulling-application-off-of-a-nrf9160-dkI am working with a 9160dk that was preprogramed card and we are looking to see if we can pull the previous application off of the 9160SiP so that we can modify it for testing. Is there anyway to do that through the nRF tools or through J-Link?

You can get a hex file of the memory that you can back up or flash to other devices but it will not provide much info about the application.&nbsp;<br /><br />But if you are using a nRF9160DK that was new and was flashed with the SW that came with it in the box then we do have this available.&nbsp;<br /><a href="https://www.nordicsemi.com/Products/Development-hardware/nRF9160-DK/Download?lang=en#infotabs">https://www.nordicsemi.com/Products/Development-hardware/nRF9160-DK/Download?lang=en#infotabs</a>&nbsp;<br /><br />You can find examples here:&nbsp;<a href="https://github.com/nrfconnect/sdk-nrf/tree/main/samples/nrf9160">https://github.com/nrfconnect/sdk-nrf/tree/main/samples/nrf9160</a>&nbsp;<br /><br />Regards,<br />Jonathan</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/433059?ContentTypeID=1Mon, 26 Jun 2023 20:55:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d26ab8d8-e060-4331-a8fd-f0a086792cccpdj1183<p>Ok so I was able to save the memory from the v1.1.0 device as a hex file so that part is solved, but I am still having the issue of connecting to the v0.8.2. Are there any tips out there?</p><div style="clear:both;"></div>
