You may remember that just a few days after the release of the Xbox One the NAND was successfully dumped revealing the NAND size to be the same size as that of a Corona (4.9GB ) and that the Next Gen console's NAND couldn't be dumped using J-runner as it is too big.
However Team Xecutor have released a tutorial which shows you how to correctly read / write the Xbox One NAND filesystem.
Team Xecutor have also produced some easy solder PCB boards that you can see in the image.
This is all another step in the right direction for the Xbox One modding scene.
You can see the full tutorial here.
