I have a question regarding Dsiwarehax downgrade (with 2 consoles): Is it compulsory to have a NNID linked in your source 3DS or you can do it without having a NNID linked? And quoting from Plailect's guide: "All variations of sysUpdater, not just sysDowngrader, have a very small chance of causing a “soft brick” once the downgrade is complete and the device reboots. This will cause the system to boot directly to the Nintendo error screen instructing users to power off the device. The reason for this is unknown, but can be prevented by performing a system format before downgrading. It seems to happen very often on systems with ambassador status or who have DSiWare installed." Does that mean I have to format target 3ds after doing the nfirm downgrade? Do I lose the NFIRM downgrade?
