Please, share the firmware of the board nRF9160-DK PCA10090 version 0.8.5, which is flashed into a new board. The firmware that I received using the instruction ( https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/getting-started-with-nrf9160-dk ) is compiled, linked but does not work. (cyclic preload). Thanks
