The signed installation methods are the same for XO-4, XO-1.75, XO-1.5 and XO-1. This was by design, since we do not wish to increase the training burden for the deployment teams, who will typically sign their builds and install deployment keys.
The unsigned installation methods depend on the type of internal storage. XO-1 has raw NAND Flash. XO-1.5, XO-1.75 and XO-4 have microSD or eMMC managed Flash.
