nRF9160 Dev Kit Bricked after MODEM update to v1.0.0

Question

Hi, I’m located in Liège, BELGIUM.

Using the nRF9160DK, an orange SIM card, MODEM firmware mfw_nrf9160_0.7.0-15.alpha I managed to make run some sample code:

mqtt_simple, using a mosquitto broker on a Ubuntu machine in our premises
http_application_update, using an upgrade file uploaded in nrfcloud as the sample guidelines suggest
- The download hostname « s3.amazonaws.com » could not be resolved.
  So, I directly used the IP address of s3.amazonaws.com (sent back by PING).
  This seemed to be a known problem of the version of the MODEM firmware.
  - Although I added the options « DNS resolver » et donné DNS Sever 1 « 8.8.8.8 » et DNS Sever 2 « 8.8.4.4 », the download hostname « s3.amazonaws.com » could not be resolved

So, as suggested on several posts/tickets in the forum, I updated the MODEM firmware to the latest version v1.0.0 using nRF Programmer. I also updated all the tools, the SEGGER Embedded Studio (4.18 win x64) and the NCS folder to v1.0.0 as suggested in https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/how-to-get-production-version-v1-0-0-to-nrf9160

I can assure you that I always use the “erase all” button in the nRF Programmer before writing an application merged hex file.

Updating the modem firmware started to raise a lot of problems for which I can’t find any solution and so my board is more or less bricked!

I can’t program the MODEM to back to previous versions. This leads to errors. Whether timeout or another error.
I can’t run at_client, asset_tracker nor http_application_update.

at_client leads to kernel panic.

This kernel panic is referenced in the forum https://devzone.nordicsemi.com/f/nordic-q-a/49264/unable-to-update-firmware-on-nrf9160/196300#196300

I did the upgrade of the modem using the programmer. But I cannot use at_client to check the version.

Any idea. Now, I can't simply use the board.
