Is there a list of compatible SD readers? I have many choices near my place, so that's not a problem.

There's a list of all of them

Many thanks LEL.

Will buy one tomorrow and share my result, it should be a success for sure.

EDIT: Just tested and it goes black screen, but the notification led blinks in red, is that any issue known?

So i have an old 3ds here to mod for someone after something went wrong and it resulted in black screen boot, turns on but just black screens (messing with cia's on sysnand isn't smart lol).

Modded it, restored nand backup and it's still black screen booting. Any idea what's going on? @hundshamer @gamesquest1 or anyone got any idea?

Edit: Don't know what was going on there but it is now booting normally except it "Cannot display the software on the SD Card. The SD Card could not be accessed". And it isn't read game carts...argh!
I hate this system!
Yes everything is plugged in properly.

Basically when i try to do ANYTHING I'm met with the "An error has occurred. Hold POWER Button to turn of.... screen. This after formatting the sd card to get it to work. Tried with one of my sd cards too and get the same result.

do you have any pictures of where you did the mod?
it could be a short somewhere or a damaged component causing issues, i have a 3DS that someone had tried to mod themselves and it no longer reads SD cards, just says the same "cannot access the SD card", never actually figured out what the issue is, its just been sat in the parts box as there is a few things wrong with it (camera is faulty, card slot had been hacked to pieces where i guess they had tried to access the clk point behind the card slot or something) other than that it all works fine, plays games fine, just cant read a SD card

OK I wanted to test to see what would happen if I solder a wire. So I soldered a wire to the gnd and tried to turn the 3ds on but it only flash the green 3D 3ds icon. Is that normal?

Soldering a wire to Gnd shouldn't do anything. So if the 3ds boot chNged from before the solder. You've fucked up somewhere

Lol you're probably right at least its just an 3ds not even going to try and figure out if the GND solder joint has bad connection after I added wire. But this thread is great info just to tired to look at it.

Quincy · Jul 14, 2015

so, 1 question. I have to remove the mod again to use the 3ds? Is there a more convenient way, like an usb port or whatever to solder on the 3DS?

You dont need to remove the mod. The blue screen only shows up when you plug the 3ds into an SD reader, because the pins connect. Typically people use connectors like microusb to make a permanent mod.

I could probably use some help. I bricked my XL and my O3DS, and recently, unbricked my XL.
I've been working on my O3DS all day, and I've had what I feel like almost every errorcode.
I'm currently getting:
BOOTROM 8046
00F800FE
00000000 00000000
00000400 00000000

I'll plug the 3DS into the computer after it bluescreens, but it wont detect the SD card, only the reader. It's the same reader that worked for my XL too

metroid maniac · Jul 29, 2015

Are there any services for NAND modding a 3DS in the UK or Europe?
I recently bricked my 3DS after misusing SysUpdater, but I fortunately have a few working NAND backups. I'm quite sure I lack the expertise to perform the mod myself unfortunately.

I have a O3DS that gives the black screens of death. Blue power led lights up and system stays on.
Already taken the system apart to look for problems. Not the wifi card, flex cables, or screens.

Shorted DAT0 to GND and got the blue boot error screen.
I did not break this system, guy that owned it said it just stopped working.
Was in storage while they moved, and would not work once they found it.
My thoughts are that they left the system in standby, packed it away, and the battery drained to zero.

So maybe the Nand is corrupted somehow? If you unplug the wifi card and turn the system on, after around 10secs or so the wifi light will flash quickly as if it is transfering a small packet of data. It does not do this if you leave the wifi card in on power up.

Since I do not have a Nand backup for this unit, are there any other options to recover it? The L+R+^A+Power does not work.
If nothing else, could I flash a Nand backup from another system and just perm disable the wifi?

"Just stop working".. Orz. So he didn't notice any clues?
No NAND backup? I hope he only used it to play purchased games, cause every pirate should back that up..
That wifi blinking? If orange that is doing its "passby". Even not hotspot for it. That's normal.

NAND is encrypted, console information involved. You can not just flash other's nand, except the special one used in nintendo factory.
* Reflash a new NAND chip: maybe he could keep his saves.
if that is just the NAND chip runs out of its write cycles, you may dump the backup from chip, and flash that to another new chip and set it to see if working.
* Send to nintendo: I don't know if the saves would still be there.
if he only play purchased games with that console, you may get it to nintendo for repair. System would be updated to latest - to be noticed.
* replace motherboard: All save lost if not stored in carts.
You could consider this as getting a new console. See this: https://www.ifixit.com/Guide/Nintendo+3DS+Motherboard+Replacement/6017

Hope the console could still be repaired. (Hope it is just played too much.) Good luck to you.
Notice: I'm not familar with the hardware. I could make some mistakes. I suggest you to get to #3dsdev on efnet.org to ask some experts for advice.

I just talked to him again last night. The unit was never flashed with any kind of game or flash cart. No cheat save mechanisms where ever used.
I asked him if the unit was dead when they found it in their storage from moving. He said no, which seemed odd. If that is true, the unit had to be powered off because it would have been completely dead if it had been left in suspend mode. Which kinda kills my theory that it bricked from the battery being completely drained while in standby.

Reading around, this seemed to be a fairly common issue. No one ever offered a solution other than "send it to nintendo" which is not fixing the problem, besides the point that the amount of $$$ you will pay to have it fixed cost near the price of a new unit.
The O3DS has been out for over 3yrs now. Someone somewhere has to have found a solution to this. Just wish I knew where to look.

There has to be some way to make the system reset to make it clear the error.
If I could manage to get a dump from the Nand, maybe it could be edited to make it reset back to factory default.

Another idea would be to flash a nand backup from another system, then after it boots, flash the backup made back to it again.
That would most likely still put the system right back where it was to begin with. No boot black screens. One can hope though right?

Correct me if I am wrong, but flashing a Nand backup from another system will not brick the unit? You would just have duplicate systems with overlapping info. I do not intend to run the system like that because I know it will cause problems.
One thing I am not really sure of. If you were to flash a Nand dump from another system and both units are not on the same FW, would that cause any potential issues? I have no idea what FW is on the broken unit, and neither does the owner.

NANDS are encrypted. Flashing another console with a different NAND will cause a brick

Then i feel so sorry for him.

* Flash other's nand dump would surely cause a brick, cause NAND is encrypted..
* If the chip just runs out of its write cycle (lifespan) and you're able to dump the chip then you might replace the chip and flash the dump from original.
- This is cause when NAND wore out, You could read the chip but not write to it.
- Edit: cause pirates offen uses emuNAND which directs IO to SD card, its NAND wears much more slightly than it should with sysNAND. Longer Lifespan.
* If he has emuNAND SD for this console.. You could ask for how to modify the emuNAND to make it flashable for console.
- Not always practical. emuNandTool could extract/inject the partition, which is with slight differences from the hardware dumps.
* Only if you've have the fat16 xorpad of the nand of the console, you could decrypt it. Or else, sorry no way to edit it.
- There was a guy asking for using other's dump and xorpad and his, to decrypt and remake a nand dump, to downgrade his. Not Safe At All. and, Not Experimented.
- However this would merely happen, cause those having xorpads could easily pirating games, and first of many tutorials, get the GW nand dump - most of them keep it.

Have you asked guys on #3dsdev about this? If so, did they offer you any other plans?

Deleted-368796 · Sep 5, 2015

Thanks for the input guys. I am still new to the 3DS scene if you didnt figure that out already. LoL

No I have not been over to #3DSdev yet. I suppose that will be my next move.

Hi,...

I'm trying to unbrick my o3ds black screen (I did a writing with sysupdater but it interrupted in the middle of the process)

I've everything connected, and when I connect to my laptop, I get this:

BOOTROM 8046
ERRCODE: 00F800FF
CFCFFFFF FFFFFFFF
00000022 00000000

Windows detects the removable device but tells me that there is NO DRIVE INSERTED, so I am not able to continue.

If the soldering points were incorrect, I should get the message ? What can cause the fact that windows tells me that no drive is inserted ?

I'm on the last step of this particular nightmare. I want to wake up.

Thanks in advance !!!

Are you using a compatible SD card reader? Go to the n3ds Nand hard mod thread and there's a list of compatible readers for o3ds. Buy one of those, that's usually the issue.
If it's not that, then your wiring needs to be redone

Thanks for your answer... I'll give it a try.
