Hey Markus,

Thanks for helping out. I'll summarise for anyone (and myself) reading this later:

Start by booting into recovery mode by powering on and holding SW4, connect it over usb
Download the application and firmware combo
Extract the contents from the zip into a folder
from the "img_fota_dfu_hex" folder, pick the connectivity bridge hex.
load it into the programmer and hit write.
after that, reboot while holding SW3
You can now write the firmware update zip.
reboot again by holding SW3
You can now flash the at client hex.

I got it working on my side now. Thanks again for the help.

[quote user="Sevn"]Thanks for your answer. I'm trying to flash the pre-compiled .zip file from https://www.nordicsemi.com/-/media/Software-and-other-downloads/Dev-Kits/nRF9160-DK/nRF9160-modem-FW/mfw_nrf9160_1.3.1.zip. This is the program which causes the error. Is this what you mean? I can't find any specific AT client for the nrf9160 platform.[/quote]

Thanks a lot for your feedback, Sevn!

We provide a separate application and modem firmware package for the Thingy:91. The modem firmware itself should not be any different, but it could be a good start to flash both the pre-compiled AT Client and Connectivity Bridge. Are you able to do so?

Regards,

Markus

Hello Sevn,

which firmware package are you picking the modem firmware from? Are you able to flash a pre-compiled application, like e.g. the AT Client?

Regards,

Markus
