The following unit was used within the factory during the production of the Nintendo 3DS. It is a 1.4J_dev system which has been modified. Below is a photo of how the unit would’ve been set up.
Some interesting photos were able to be recovered from the NAND. The first image appears to be some sort of factory equipment, however, it is hard to make out exactly what’s going on due to the filter which was applied to the photo. The second image is likely a worker at the factory. (Face blurred for privacy).
