Hacking 3DS unbricking progress

[jcipher]

I wonder how many people without backup nand has emunand on their SD card. They could probably extract it for the unbricking process assuming it wasn't corrupted. Of course if it's higher than 4.5, the 3DS won't support the flash carts anymore.

Considering that the entire point of having emunand is to emulate 7.0+ firmware, I doubt too many people made and kept their 4.5 emunand back-ups, especially if they couldn't even bother to make an actual nand backup.

There is a menu which shows up now if you watch the serial monitor, use that... AND DONT FORGET ABOUT VOLTAGE DIVIDERS

I will be using an SD shield, it has a voltage switch to set it to 3.3v easily.
I have to find out how to connect it to the Arduino first.
Total noob here

 

[krisztian1997]

lol, just look up on the internet, connecting the shield is the easiest part

 

[Moquedami]

Now to the totally stupid questions:

1) In wich order do I have to set up everything before start? First connect the 3DS to the SD shield of the Arduino, then the arduino to the USB port of the pc?
2) Does the 3DS have to be powered on?
3) After the erasing process, do I need to desolder the fifth cable (DAT3) to do the Nand writting process with a SD adapter?

 

[krisztian1997]

1) Thats not important, sometimes the initialization fails even if you plug in the 3ds before starting the arduin, but the best is to plug in the 3ds, plug in the arduino then power on the 3ds
2) yes, after you started the arduino
3) nope

 

[khalaan]

1) I connected the 3ds to a micro->sd adapter and just plugged that into the shield, and moved it to the pc without desoldering dat3/cs
2) Yes
3) See 1.

Hope for you, guys

My bricked 3DS XL was changed to 3DS with 3.0.0 FW in shop, epic win

How did you manage that without your NAND backed up?

I looked and found some schematics, but I´m totally new to this and I don´t know how to read this stuff.
I´m sure it´s really easy but I´m like WTFITS?!!!!

​

SD reader - Arduino
GND -GND
+3.3v - ICSP +VCC
+5v - NC
CS - Pin 53
MOSI - ICSP MOSI
SCK - ICSP SCK
MISO - ICSP MISO
GND - NC

I just said, that it was broken in update progress. They told me: OK, here is an absolutely new 3DS with 3.0.0. FW. Is it good? Me - maaan, that's right firm... I mean, good console

 

[krisztian1997]

Look at this instead http://www.gammon.com.au/images/ArduinoUno_R3_Pinouts.png , if you still dont understand PM me with your arduino model and who made the SD shield and I help you

 

[Moquedami]

Thanks man.
I´ll try to figure this out when I get home with all the parts in front of me.
In case I have more doubts I´ll take some pictures

congratz, i picked up a dirt cheap 3ds original for spares was only £50, was on 2.2 but updated to 4.x now,

Remember to dump your nand now

Hello! I'm preparing to get everything up to try to unbrick some 3DS and I decided to "consult" with you guys what is the best.

So far I only have an Arduino UNO rev3. I'm trying to figure out what's the best Shield to get
http://produto.mercadolivre.com.br/MLB-535994477-modulo-sd-card-para-arduino-e-pic-_JM
http://www.labdegaragem.org/loja/31-shields/sd-card-shield-v4-0.html

Which one of these two should I buy? The first one is a really cheap one. I don't see any jumper to switch between 5v or 3.3v. The second is a little "fancier" one, with more pins and jumpers, headers, etc (which doesn't make sense for me, cause this is all new to me). Anyway...

I'll be following khalaan post 4901895, on how to set up my windows environment and Moquedami (post 4902110) and khalaan (post 4902114) again on how to connect everything up. I just need to figure out how to connect the Shiekd to the Arduino.

This shouldn't be that damn hard...

Any advises on which Shield to pick and how to connect it to the Arduino is appreciated.

Thanks!

Adding to the post above, the seller for the first Shield told me the Shield recognizes the voltage automatically. If that's true, how the heck I tell the Shield to use 3.3v instead of 5v? Is the Arduino Uno able to do that?

Nope, but I used exactly the same model like the first shield and its just perfect, never had a single problem with it. I am updating the github with a simplified instructions how to do it with arduino... except that I cant format that readme.md correctly

Thx krisztian1997 !
I'm buying the first one then.
Please, let us know when you update the github.

Cheers!

Updated the readme, I hope that this time the table stays there and commas dont dissapear again

Oh crap!
I just realized I bought that shield without the jumper.
Please Kristian, confirm there is no need to further modifications to set the voltage to 3.3v
