Please check out this <a href="https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/how-to-program-any-project-to-the-thingy-91-with-dfu">blog post</a>&nbsp;for instructions. Native support for this is available on the master branch of NCS through <a href="https://github.com/nrfconnect/sdk-nrf/pull/4621/files">this pull request</a>. You can consider using that instead.<br /><br />Best regards,<br />Carl Richard</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/322556?ContentTypeID=1Fri, 30 Jul 2021 02:32:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3f379e85-4636-4b7a-9184-1cadb3a4d5e8ibiglari<p>Just as an update to prevent confusion, this message appears <span style="text-decoration:underline;">after</span> the hex file is uploaded to the unit. The progress bar goes all the way up to 100 before showing the error.</p><div style="clear:both;"></div>
