Hardware N3DS NAND backup possible, I hope.

[Ninoh-FOX]

No no, i downgrade 10,2 to 9.0 from hardmod. But the system is inestable, them i try rewrite again the nand with decripte9, but nothing.

The nand.bin is ok because i used the some file with gateway for downgrade 9.2 (gbafirm+msetdown) to 9.0 original

I am lose...

updating to 9.2 with sysupdater, you might have not properly installed the downgrade

 

[Ninoh-FOX]

mmm, this is a nightmare !! Someone made downgrader from 10.2.0-28? Because this problem has been to root me there, I have not had problems before, and now decryp9 or gateway not rewritten while the nand (before rewritten fine...).

 

[Ninoh-FOX]

I have going to tried with the four points dat... I wait that this fix the nand problem in me console...

@Ninoh-FOX, first off, I don't want to be rude, but you have the worst English ever. It is almost impossible to decipher your posts. One of them sounds like you used the gateway downgrader to go to 9.0, but there is no such thing. You're saying that you flashed your own 9.0 nand.bin with the gateway menu?
Then there should be nothing wrong. What exactly do you mean "unstable"? Have you tried upgrading to 9.2 using a SSB cart, or with mini pasta? (Or any firmware with a working devmode). And I don't know what you mean about decrypt 9 flashing... Above 9.2, decrypt 9 wouldn't have the permissions it needs to touch the nand.

Hmmm my inglish is bad, i tried tell my problem.

1. New 3ds sysnand 9.0
2. Backup nands 9.0 and 9.2 (works fine) with gateway menu.
3. I used sysnand 9.2 backup for make emunad, late update to 9.5 for sysupdater, all ok
4. I update sysnand 9.2 to sysnand 10.2
5. Make hardmod (only dat0)
6. I tried make backup 10.2, backup ok about 90%.
7. Reboot console, system corrupted (¿¿??)
8. Downgrade 9.0 (nand.bin is ok, same file that emunand)
9. System corrupted.
10. Restore nand with gateway and decrypte9, system corrupte...
11. Tomorrow i try restore nand with 4 dat pinouts....

So you flashed your console with your emunand? Or a 9.0 backup? Sounds like your backup was corrupt or the wiring was wrong
And what do you mean the 10.2 backup was 90%? Do you mean it never finished dumping it? If so, why the fuck would continue without a 10.2 backup and why would you then flash your console if you knew it only 90% completed

 

[Ninoh-FOX]

Nand 9.0 is ok, i downgrade 9.2 to 9.0 with gateway and all ok. It Is the nand that i try restored.

Corrupte backup 10.2 only is for extracte seeddb.bin.

But i tried backup 10.2 (fail to 90%) i could not restore ok nand 9.0 any more.

The console write nand 100%, but anytimes i cant write nand to 100%, then i may turn power off the console, wait about 5 min and try again, then i can write the nand ok, but, when i turn power on the console anytime boot ok and other not, and if the sysnans boot to the short time say "error, push power boton and try boot again".

Sorry my english, i haven,t problems for read, but white is...

 

[urherenow]

You CANNOT run decrypt 9 on SYSNAND 9.3 and above. It will never work. The ONLY way to dump your SYSNAND on 10.x is using your hard mod and win32 disk imager. If your hard mod is wired correctly, and you have an SD reader that is compatible with the N3DS (it is very picky!), then you should get a 100% good dump, and flashing either your 9.0 or 9.2 nand.bin files that were created with the GW menu should also work 100%. Decrypt 9 is only used on 9.0 or 9.2 SYSNAND to generate your xorpads.

I finally repaired my new3ds with the four dat point XD thank a lot!!

(the wifi module not...)

 

[missinsummer]

Spoiler: right now

here is what it look like right now, the 4 wires are

black: GND
red: CMD
white: CLK
green: DAT0

am i doing it right? i didnt have it plug into my pc yet and as soon as i turn on, it becomes like this blue screen? form this youtube video, i can see it should be normal bootup tho.... assume my circuit and soldering not shorted, i must break the mother board?

Spoiler: some of my wielding job

i use a 10$ solder and very thick flux since those are what i have atm

this is not my photo but i use the same location for ground, and it feels solid.

here is the problem:

i turn on first , and it gets blue screen, then i plug this thing into PC, the pc made a sound of something has injected(that usb insert sound), then nothing happens, not even asking should i format or not.

after that, i open Disk manger, the device is not showed, as if there never had a USB plugged in.

i start to wondering if it is to do with my SD card and SD card reader ! since both of them are really cheap,(from those tinydeal giveaway, basicly freebies)

Spoiler: my sd card and reader

plan: a visit to local electronic shop to see a good SD card and reader.

question: does the SD card has to be those bridge-card? like TF card reader ?

its like reader into reader into reader....why those 4 wires can not be made into a USB2.0 at first place?

PS: the purpose i am doing this is only trying to downgrade from 10.1 to 9.2.

 

[urherenow]

Don't think you used the correct points there. You should not get a blue screen before you connect an SD card adapter...

 

[missinsummer]

thanks for reply.

now i am feeling i fked up everything....by break little part of the mother board...

so if i only have 4 pinpoints wired but not connect to TF-card-reader yet, when i put my 3ds back together, i should be able to boot nomally? unitl the moment i have it wired to an TF-card-reader?

Ohhhhh, this is correct, because from the video, the 3ds was normal unitl he connect TF-card-reader to 3DS via mini-usb connecter!

so the TF-card-reader is more than a dummy structure, it has chips init?(i am not talking about SD-card-reader),(or to do with the internal wiring of an TF-card-reader?)

Spoiler: my TF-card-reader

 

[missinsummer]

any other CLK pinpoint for me? the one i did with was really hard one >.< #811

 

[missinsummer]

very quick update,

i removed CLK wire as it looks problematic for me, (the data0, CMD, GND is still wired, but at this point, nothing is connected to SD or TF card reader, just cabling)

Spoiler: troubleshooting

MY 3DS boots normally!!!!i am so happy at this moment.

at least nothing has fked up!!! and i am sure my CMD, DATA0 soldering was good as well!(after double checking with magnifier any shortage near soldering point)

so it is just a matter of knowing an alternative CLK pinpoint and getting a good TF&SD card reader!

 

[hundshamer]

Here are the points I use for your model:
https://www.flickr.com/photos/hundshamer/shares/0VP125

 

[missinsummer]

I moved my GND to new position so was CLK,

Spoiler: CLK GND

the black wire is GND, which was extended a little bit as you can tell from the expose join part which get wrapped later on.

, double checked DATA0 and CMD as well, i am 95% sure my soldering should be fine.


Wired to TF-card-reader, turn on 3ds, boots into normal system.
Put TF-card-reader into SD-card-reader, turn on 3ds, boots into blue screen.


At this moment, i am pretty much sure about everything to the point of TF-card-reader are ok.

Then:

1. IF i plug my TF-card-reader straight into my MacBook pro, the mac doesnt detect any thing,(neither in disk utility),(since The SD-card-reader is built-in, i have to plug the TF-card-reader in first, then turn on 3DS to get the blue screen, then wait for Mac to response. I am not even sure should i do this.
2. I plug TF-card-reader into SD-card-reader, then plug into my Windows PC, nothing shows up, nor in Disk management.

That pretty much leave me on conclusion which is my SD-card-reader is faulty,as well as my MAC's SD-card-reader doesnt work with this project. otherwise, i still have somewhere fucked up(But the fact that 3DS can boot into normal system makes me think at least my soldering job did not affect the device in a negative way. Thus I feel like "I did have done the job as what was supposed to be done").

will buy new reader tomorrow, time to sleep!

 

[missinsummer]

just make sure you haven't lost the little lock tab on your SD adapter

what does the lock button do? my SD card is like almost naked... over stripped .....

 

[hundshamer]

Use tape, but it should still show up as a drive. It shouls also be able to read. Without the lock tab, you will not be able to write to the 3ds's NAND.
