Thingy:91 nRF9160 firmware 1.1.1 update

[Mohamed]

I had updated Thingy:91 nRF9160 firmware to 1.1.1 using nRF Desktop Programmer. I used the "Cellular Modem" button and attached the new file mfw_nrf9160_1.1.1.zip

However, after the update finished successfully and restarting the device,  the modem doesn't work, LEDs not working and all AT commands time outs.

Does that mean I broke the firmware, if so how to solve that?

Hi,

I had the same, but flashed application hex file after and it starts working. I also managed to connect to nRF cloud.

Note, that NB IoT image did work in my location and I had to use LTE-M (Cat-M) hex file.

Cheers,

Alex

Yah true. I re-flashed the image and it is working now.

Many Thanks :)
