The microSD reader's PCB sits quite nicely on top of the 3DS XL's NAND chip along with something to hold it there like blu-tak or glue. So I ripped it open and found out that it does. I just so happened to have bought a few of these lovely super tiny microSD readers from DealExtreme, and being so small, I wondered if I could open it up and use the internal circuitry of this inside of my 3DS XL, in the same fashion as a modchip inside of any other console. (I do not know the specifics of what would happen, but I certainly do not like the idea if accidentally connecting power directly to a data or signal line for my 3DS's NAND at any rate) This could be dangerous is say, someone were to connect something that was actual USB to this port, as the setup is NOT USB. Also, the pinout depended on the pinout the modder decided to make for it. I liked the idea of using a microUSB port just like a lot of other consumer electronics, but they were just using a microUSB form factor port, connected directly to the 3DS mobo's eMMC testpoints, meaning SD protocol wa going over them, not USB, along with a custom cable with a USB plug at one end, connected to an SD adapter or reader. So this was a problem.Īnother problem I noticed was in regards to people using microUSB ports in their implementations. After a while the FFC cable's connector wore out and eventually broke after repeated use too.

I also did this myself at first, using a Sparkfun brand microSD sniffer combined with a FFC cable plus corresponding connectors that I pulled from a dead printer.īut when I used it I had to be careful since the FFC cable from the mobo to the sniffer was rather short, and it had to go into a card reader before going into a computer.
#Nand x reader software#
This is most useful for one with a 3DS XL containing a vulnerable system software version for homebrew (version 4.5 or lower), as it can allow to make a complete backup of the 3DS's NAND including the vulnerable system software, and then also reflash and actually downgrade the system back to that system software version should the system be updated past a vulnerable version for whatever reason and the user end up requiring the vulnerable system version once more.Īnyways, as the thread has progressed and people have made their own implementations of accomplishing this task, I noticed a certain trend in this, mainly that they were using their own connectors that were exposing the motherboard testpoint connections directly to outside of the 3ds, and then having to connect that to an SD reader before connecting to a computer (or connecting to an SD slot on teir computer, which also requires they build a custom cable to achieve this. I assume a lot of you would know of the great nand flash dump (3ds xl) thread that was created a while ago with all the info about connecting your 3DS XL's eMMC NAND via the 3DS's motherboard testpoints to an SD card reader to be able to read and write to said NAND, mainly to make backup dumps and restore them if necessary. A few days ago I ended up modding my 3DS XL (well, again, but a better way) with a much cleaner USB-based mod.
