Contrary to the iPhone 6 series, error 4013 on the iPhone 6S is usually Baseband related.

You don't say if you have any micro-soldering experience so I'll put this out there for general reference. You will need to closely inspect the Baseband area of the logic board. There could be some loose coils or shorts/defective LDO's from the Baseband PMU. You will need to probe all of the outputs to insure everything is okay

The issue is usually caused by the NAND chip.

Sometimes it only needs to be reprogrammed but sometimes the NAND chip can also be bad which would require replacing it as well.

There is an indepth video on how to do this here:

Edit: As said from the other answer, the issue is more likely related to baseband more than NAND.
