Hacking 3DS unbricking progress

[gamesquest1]

Mid January with 3dslink launcher.dat, I'm going to resolder and run your tool once again. Thanks!

try make your wires as short as possible, and just try soldering the SD adapter wires straight to the motherboard (i.e no usb ports) it will help eliminate issues

This message could appear when SD adapter is not sufficiently embedded in the Raspberry's card reader...
The SD cable should have a max length of 25 cm in total, no more.

Thank you tempers! I'll try in the next days! I need a new solder iron and rewire with short cables, I'll keep you informed.

Would it possible to downgrade the 3DS firmware using this unbricking method ?

if not, could someone explain whats the difference between what is being flashed on the unbricking process and where the current firmware is stored?

No, this only unlocks a locked flash chip. It doesn't alter existing firmware. YOU CAN NOT EVER DOWNGRADE IF YOU HAVE NOT MADE A NAND BACKUP BEFORE UPDATING!

The ONLY way we will ever see downgrading without a backup happening is if someone completely cracked the encryption scheme used by the 3DS and wrote a program to retrieve the private key from the 3DS (it's unique to every unit produced) and in combination with the common key (likely not found yet either) re-encrypt a 4.5 or older firmware to a perticular 3DS unit.

If that condition is met we will already have some kind of CFW anyways or not even have a need to downgrade because at that point we can sign and encrypt whatever software we want (including homebrew and rom loaders) and it will run as if it was an official Nintendo app. The 3DS won't know the differance.

However this is HIGHLY UNLIKELY TO EVER HAPPEN!. So please stop asking about this.

Hi everyone my 3DS XL is still bricked after tried unbricking with Arduino Uno.
I tried multiple setups:
1. With 74HC125 and 1117-3.3 for voltage converter and this LC Soft SD card module circuit (I created my own http://www.element14.com/community/servlet/JiveServlet/download/40595-65625/lcsoft SD module.pdf).
Result: Sometimes detected, but with CID 0xFFFFFFFFFFFFFFFFF...
2. With CD4050BE and 1117-3.3 for voltage converter and this LC Soft SD card module circuit (I created my own http://www.element14.com/community/servlet/JiveServlet/download/40595-65625/lcsoft SD module.pdf).
Result: Never detected. After unwiring my 3DS won't turn on at all. To turn it on I need to connect the charger and battery to my 3DS -> strange (battery voltage is 4.13v).
3. Wire it to SD adapter and connect it to Laptop SD card reader.
Result: Not detected at all.
4. Modified my Arduino Uno to work at 3.3V and wire it directly to 3DS with some capacitors and pull ups from http://www.element14.com/community/servlet/JiveServlet/download/40595-65625/lcsoft SD module.pdf).
Result: Never detected.

Anyone can help me reviving my 3DS from death, and the battery problem? Thanks.

IIRC the ardiuno uno is not compatible, not sure what's going on with your battery though

Try get hold of a raspberry pi seems a lot more user friendly as you dint have a bunch of possible causes for incompatibility

Thanks. Will try get a Raspberry PI soon.

Just wanted to report I have done 34/34 successful unbricks and have 3 more in the way. I'm using Raspberry.

Hi! I have a problem with 3dsunbrick... while running I have this error:

EMMC: resetting controller
CMD0: idle
CMD1(0) : init and querry OCR
CMD1(0x00FF8080) : repeat untill ready
CMD2: CID and id mode

Warning! The CID is an unique serialnumber which might be traceable. Do not publish it in any way!
CID: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

SD_init: error sending CMD42, error = 00200000. Giving up.

(D)edication | (S)afe run (Querry only) | (U)nbrick (Safe) | (Q)uit

maybe something wrong with my solder points? thanks in advance.

Did you put the small plastic piece that locks and an unlocks the SD reader from writing to it?
You can add a small piece of tape across to enable writing to the SD adapter.

Hello,

I got a brick of my 3ds XL with r4i deluxe card and unfortunately haven't made nand backup, is there any way to unbrick it ?

Yeah, you can unbrick using the raspberry pi without a NAND dump

 

[mirakl577]

But I searched manuals and didn't find any tip with restore process without nand backup.

Could you please send me the link it would be very helpful.

Thanks.

Most of the tutorials are outdated even this video is but I put captions over the video to let you know when to stop

great, thanks!

oh, I have one more question, can I use anything else instead of raspberry pi device, maybe notebook for example, because I don't have it yet ?

Only a ardiuno....not to say its impossible to use anything else, just that you would have to do all the work yourself and it wouldn't be as easy or straight forwards as using the raspberry pi

For the arduino a logic converter IC (I MEAN AN IC CHIP) is needed, I have tested with 2 sd shield that uses IC to step down the voltage but not working...All the connections are fine cuz the NAND can be detected with RPI.

Hello to everyone!

I converted my teensy 2.0++ (with voltage regulator) with teensyduino,i soldered it to the 3ds xl,I connected the teensy to the pc and powered on the 3ds using the battery. This is what I have with serial monitor:

Enabled outputs/inputs
Initialized SPI with 250khz frequency
Waiting the minimum 80 cycles for warm up
Keeping CS line on low for communication
Reset command sent on MOSI, but no answer from the slave. Please check your card connection/soldering
Initialization failed
Retrying...

Initialization failed after several retries

What should I do? I noticed that the GND is different in the arduino uno schematic,but the result is the same
