Thingy91 unable to progress past the update firmware step

[morerook]

Hello,

I am stuck on the step of getting the Thingy91 to start working.

I am following this tutorial: https://www.nordicsemi.com/Products/Development-hardware/Nordic-Thingy-91/GetStarted

I uploaded the Modem firmware with the nRF programmer, followed by the MCU firmware. However, no LED lights are turning on for the Thingy91

I tried to go back to upload the modem firmware again, but when I press the modem's button and turn the device on, I can't find the device, and I am unable to reflash the modem's firmware. The device does not appear on the programmer.

I'm not sure how to proceed from this step.

nRF52 firmware: thingy91_asset_tracker_ltem_2021-06-28_7a076c22.hex

modem firmware: mfw_nrf9160_1.3.0.zip

Thank you

It doesn't reach Step 7. It never connects to the LTE network because it never reaches the step for user association - it just keeps blinking white.

Okay, I see. Sorry for misunderstanding you here.

I have registered the SIM on the nRF cloud. This was what I got when I tried to register the device on the nRF Cloud

Yes, that is correct. The device can only be added to the nRF Cloud when it is connected to it and has reached the association point.

We might want to take a look at your connecting to the network, then. Could you please provide me with a full application log that shows the connection attempt to the network?

Thanks and regards,

Markus

Would that be the log from LTE Link Monitor?

Yes, exactly!
