Hacking 3DS unbricking progress

[admin]

I decided to create a new thread with the our progress of unbricking the 3ds because there are several threads talking about this and its very hard to find anything by now in the threads.
So far we found a way to lock a normal card and it acts exactly like a bricked 3ds, doesnt shows up in windows explorer, cant write to it using any other tools or format it. All what we need now is someone willing to test our code on a bricked 3ds. Our code can be found at https://github.com/krisztian1997/3dsunbricker , its based on Roland's library with some custom code made by ryuga and me (thanks Coto for the CRC16 algo)
Forgot to mention, hardware mod is needed, we are using an Arduino to test our code on a SD card, but its exactly the same wiring like the one for nand dump except that DAT3 is also needed for CS. You need an arduino to can communicate with the eMMC controller directly, also some ways to reduce your voltage to 3v3 because arduinos I/O use 5v, the easiest and best way is to get a SD card shield, or if you cant get one, another good solution is an voltage divider with resistors, like this or this
Progress so far: Unbricking is possible now, there are around 10-13 confirmed unbricking with the raspi and 3 with the arduino

RaspberryPi

Use this repo if you own a raspberry pi, the readme has a detailed description how to do it https://github.com/bkifft/RPU

Arduino

This repo is for arduino owners, while the code works perfectly, if you use a resistor based voltage divider, it wont work because the eMMC chip needs a perfect clk line and data lines (square-ish signals, what cant be achieved with resistors) https://github.com/krisztian1997/3dsunbricker
