Hacking 3DS unbricking progress

[ryuga93]

Mhhhhh........I tried erasing and locking the SD card but it doesn´t seem to have any effect on it.
When I connect it to Windows it shows it normally. No lock of any kind

Can you post the serial monitor log for locking,and what type of sd card you tested?

 

[Moquedami]

I´m using a128mb Kingstone.
This is the log now:

Enabled outputs/inputs
Initialized SPI with 400khz frequency
Waiting the minimum 80 cycles for warm up
Pulled CS line high to start communication
Card is in IDLE. Checking if the voltage is correct.
This is an SD (SD1) card
Set SET_BLOCKLEN to 512 byte
ReadCardStatus = 0,0
Password status: unlocked

u - UNLOCK
l - LOCK
e - ERASE
x - TERMINATE EXECUTION

Starting locking procedure
Done

Windows still detects it fine with all it´s content

Back to the shield.
Let´s see what happens when I try to erase it.

Still intact in windows. Even with it´s content.
I don´t know what´s wrong. It´s like its doing nothing to it.

I´m gonna try with a different SD now.
A Markvision 256mb

This one appears succesfully locked. It´s not detected by Windows.

Back to the shield, it is correctly detected as locked!

The Erase is also succesfull and Windows detects the unit and formats back again.

Now for the real deal, There goes the 3DS.

Enabled outputs/inputs
Initialized SPI with 400khz frequency
Waiting the minimum 80 cycles for warm up
Pulled CS line high to start communication
Reset command sent on MOSI, but no answer from the slave. Please check your card connection/soldering
Initialization failed

Initialization failed after several retries

Can you confirm your emmc of 3ds?based on the previous post by greyneon,it is recommended to use logic circuit instead to obtain a sharp unit step function change for optimal spi connection.so we might need to change the voltage divider part not just using resistors

 

[Moquedami]

My emmc is Samsung.
I´m gonna check my solderings now just in case, but it all looked fine.
Keep it up, guys! and thanks for all your work!

Looks like samsung controller needs some logic circuit instead of just voltage divider.Thanks for the report.We now can confirm it.Will find what solution can be done

can we see your circuit ? eMMC are very sensible and sometimes dont work with resistors, raspi doesnt has this problems because the SD card reader is 3v3 by default.

New 3DS XL unbricked with Raspberry method. bkifft
1000341504 byte, Samsung KLM2G1DEHE-B101

I haven't tried with Arduino method. I'll try to re-brick intentionally

just try if it initializes...

 

[pizzatime]

No, it don't pass to the menu.

 

[krisztian1997]

No, it don't pass to the menu.

Can you post the log or PM me with it

 

[pizzatime]

The log is same as the first 3DS I tried to unbrick:
http://gbatemp.net/threads/3ds-unbricking-progress.361171/page-14#post-4903565

I'm starting to think that I've made errors in SD shield building.
I've also an ethernet shield that has a microSD slot.
This one:

I'll check connections if are the same.

Or maybe we f*cked up the code and thats why it doesnt works... but someone confirmed that our code works, so I dont know what is the problem...

We need the data sheet to know what's wrong.if you old emmc works then it should not be the problem in coding...

I am looking in the code atm and tweaking it for my arduino with modules. Example: imnnot usimg serial for debug. Im using a lcd :-P

I'll take close detailed pictures of my setup today.
I know why the test failed with the first sd cad i tried, I didn't terminate the program execution after each step.
Did it right with the second card, so the arduino - shield connection was ok.
A detail that called my attention, the error code of the bricked 3Ds with 4 cables soldered is 00000008 when it is turned on disconected of any card reader. When i connect it, it changes to 000400.
But with the fifth cable in dat3 the error remains the same in 00000008, like it isn't connected.
Maybe it doesn't mean anything.

oh my, I cant believe that I forgot to look over that bug when not terminating the execution after every step... and that error is interesting, the 3DS should turn on when its not connected to any card reader without an error

4 wires mode is SD 1 bit, 5 wires is SPI 1 bit (if CS line is connected).

the controller reports CLK line being "absorbed" from the controller(3ds), NOT eMMC 3ds, so an invalid CLK occurs in SPI mode.

the code for arduino works for SPI mode, a small flaw in the clock line, abnormal rising and latches,etc won't bring up the eMMC in SD mode ever

Guys,

I'm trying the Rasp method since my Arduino still didn't arrive. I still don't have any bricked 3DS but I decided to give a shot with my own. It's not bricked so I'll only run the s (status) command.
I flashed the SD and my USB with the kernel image and put the RPU.zip (formally master.zip) into the USB.

Plugged the HDMI, the USB and the keyboard. Turned the Rasp on and after some time I looged in and ran the 3dsunbrick command. Some seconds later I was presented with the options.
Then I removed the SD, plugged my cable (4 wires) into my not bricked 3DS and turned it on. Blue screen came in, so I plugged the SD cable into Rasp and typed s (lowercase) and hit ENTER.
Then I got this screen and I, honestly, don't know it it's ok or not.

https://www.dropbox.com/s/6h267pmwacb37lu/IMG_20140201_143918.jpg

Can anyone tell me if this is the expected output for a not bricked 3DS status?

Thanks in advance!
