Hi, sorry for delayed response.

Even the verification after flashing the Asset Tracker v2 is still failing, the asset tracker v2 app seems to be up and running.

Try flashing the board controller firmware to the nrf52840 chip on the DK. https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf91/nrf9160_external_flash.html#programming_the_board_controller_firmware

Hmm...

Well, I suggest you to ask from the person who developed and/or built the asset tracker v2 for the Quick Start application why it claims to be "My Application" and not "Asset Tracker v2".

To be sure that Quick Start app is flashing the correct image, I downloaded the "nrf9160dk_asset_tracker.hex" from here
https://github.com/NordicSemiconductor/pc-nrfconnect-quickstart/blob/v1.2.0/resources/devices/firmware/nrf9160dk_asset_tracker.hex

And then flashed it.

Hello,

[quote user=""]*** Booting My Application v2.1.0-dev-4594a8693738 ***[/quote]

what is this "My Application"? I thought you said you programmed asset tracker.

Additional info, the Quick Start Serial LTE Modem example is working just fine.
