https://devzone.nordicsemi.com/f/nordic-q-a/122108/update-firmware-modemGood afternoon we are updating some Nordic chips but to make the connection work it is necessary to install the modem version 1.3.1 wait for it to connect and then install the modem version 1.3.7. Is there a way to directly install the version 1.3.7en-USTelligent Community 13Tue, 10 Jun 2025 11:40:08 GMThttps://devzone.nordicsemi.com/thread/538642?ContentTypeID=1Tue, 10 Jun 2025 11:40:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2d8489c4-d2f1-4c41-a4e8-4e5653855a9fdejans<p>Hi,<br /><br />You could try to use&nbsp;<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/nrf_modem/doc/delta_dfu.html">delta firmware updates</a>.
