DFU for nRF9160 with max possible image size

In my experience, static partitioning is very often the source of the error. And it is often not required.

I always recommend using dynamic partitioning, with the two exceptions:

Static partitioning is required for DFU. So for your release, copy build/partitions.yml to pm_static.yml. Then you do not have to calculate sizes manually, but instead just freeze the already dynamically partitioned partitioning.
To add a custom partition. For this, do not statically partition all the device memory if it can be avoided. Instead, add only the custom partition to pm_static.yml. The dynamic partitioning will then add other partitions "around" (technically just before or after) the custom partition.

Try to not use static partitioning, and see if your project works then?
