I will present the links for the information. The 3DS can upgrade/downgrade right now. Why would this help? 1.) Returning to an earlier firmware/dash will allow exploits to essentially be permanent. 2.) This gives the ability to recover if/when the Wii U is being "played with." 3.) If there are hacks involving the read "nand" then this may be of use. As it is, 3ds publicly cannot have the nand reads MODIFIED. Future advancements may allow for modifications to be made. http://gbatemp.net/threads/nand-flash-dump-3ds-xl.350668/ --Must have an older nand dump (currently) to downgrade which is why getting backups NOW may be of use. http://wiiubrew.org/wiki/EMMC_NAND --Officially here on wiiubrew, lol http://www.ps3hax.net/2013/02/super-slim-components-and-test-points/ --First I heard of this from deadlyfoez http://gbatemp.net/threads/shadow-lags-wiiu-hacking-and-development-thread.351575/ --First post with technical information was removed due to flaming First rule of anything; have a way out. This type of work gives that and would allow people to recover on Wii U side. I don't want to misquote anyone BUT I heard the vWii nand can be recovered with infectus. Having a way to recover that would be GREAT as well. Being able to recover from anything would open it up for people to play around. Obviously those "in the know" can recover and likely have this covered. Has anyone else done this? Would anyone want to show their results (pics would be great) here? If this gets ignored then so be it.
