The thread I linked to above had all of the information.
Here it is again:
It seems the Uboot code was updated and reversed the switch position - this is the code and binary that is on the Github page. @alzhao must have privately reversed the problem and recompiled it to work correctly, but not updated the github repo. So it is still reversed in the binary that is publicly available.
With the router case on the switch can be in positions 3 or 2 (middle) which only boot to NAND, position 1 will boot to NOR but that can only but attained by removing the case or filing the case down to allow the switch to get to the 1st position.
