This guide shows you how to generate and provision new nRF Connect for Cloud certificates for your Nordic Thingy:91 or nRF9160 development kit (DK).
Pre-compiled application firmware (v0.2.3 and later) for Thingy:91 with this support can be found under the Thingy:91 download page. The latest pre-compiled application firmware for the nRF9160 DK also has this support. Both downloads (Thingy:91 or nRF9160 DK) have nRF9160 SiP application firmware for connecting to an LTE-M or NB-IoT network. The ZIP file inside the download is the modem firmware (mfwnrf9160xxx.zip), do not unzip. The modem firmware will be updated in the next step.
Follow these steps to update the Thingy:91 with the appropriate hex file (see CONTENTS.txt in the download for description). Follow these steps to update the nRF9160 DK with the appropriate hex file (see CONTENTS.txt in the download for description).
To download new certificates go into the account view in the top right corner of nRF Connect for Cloud. Then input the device ID in the format nrf-<IMEI> and PIN/HWID found on the label on the PCB into the Device Certificates card. PIN for Thingy:91 and HWID (with or without colons) for nRF9160 DK.Then click the Download Certificate button.
The device must first be deleted from nRF Connect for Cloud before the new certificates will work.

Just powercycle the device (turn it off for ~10 seconds).
Hello, I´m new to the nRF9160-DK board and trying to update the certificate. How can I get the modem from power off state in offline state?
I have the same problem as Henrik M. . I am in Germany. According to https://ibasis.com/solutions/iot-connectivity/network-coverage/ iBasis has limited coverage in Germany. Can you recommend a sim card from an other provider with good coverage in Germany?
Conclusion from my side: iBasis SIM doesn't work in Denmark.
Well, after 10 minutes, it actually got a POLLHUP, followed by a reboot. Then after around 5 minutes it connected via first PDN and then LTE! :-)
