Hello,
We have a nRF9160 product in production that is programmed with an image created by SDK 1.9.0 and with the default memory partition. We migrated to SDK 2.3.0 last August and FOTA to those product failed. Device rolled back to the older version of the firmware after reboot. We then tried FOTA to the same device twice in order to force it to run the new firmware. It worked but now we are stuck with that version and no longer able to FOTA any newer version to the device. Can someone please explain what we did wrong and how can we correct the problem? Thank you.
