Hardware N3DS NAND backup possible, I hope.

I used JRunner to backup mine

still can't get this to boot though

Ha awesome! I'm glad to hear that I'm among others from the xbox scene. Since you already did a dump what were the pins/wires you correlated to the N3DS board from the Nand-X/JRProgrammer?

Probably you got any conector unplug.

Does it fail to boot if ANY connector is unplugged?

Why not, if you get a fail on 1 lane for a bad connection you can get that error.

It fails to boot after the dump or when you try and write your backup?

Usually you need it to at least power on to dump the NAND and it sounds like it's not even booting to the error screen.

So it can fail to boot or power up and then down if one of your backlight connections is loose or not conencted. I had that issue when I first put it back together. So it might not be shorting but starting up and it never gets past POST for the device so go slow and check that most connections are back in, you don't need the mic or home button or L/R lol.

Ah I thought that it just needed to be attached to a power supply (ie battery, ac adapter) to work. Good to know.

yeah you need the screens backlights attached at least, analogue stick etc are fine to be left disconnected while working on it, i usually just plug the screens back in for testing though so you can make sure its properly working, in regards to all the nand-x, and jrunner stuff....its really not necessary, a SD reader is perfect for the job, i doubt there would be any real difference in speed compared to just using a SD reader, plus its easier to just make the SD adapter so you can use whatever computer you like with no need to have any extra devices handy

SD reader + win32diskimager = happy nand dumping, even with only 1 dat line attatched your still only looking at like 10 mins writing time max taking into account the extra nand size on the n3DS, on the normal 3DS its like 5/6 mins, if you hooked up all 4 dat lines it would be like 5 mins for n3ds, 1-2 mins for standard 3ds's

I appreciate the advice, that would be easier than using the nand-x. I just figured since I have it and I am familiar with how it works that would be best but being able to use any computer is a definite plus.

Yes that is the best way to go cause while it is a NAND it's actually a NAND packaged with a controller making it an eMMC. Unlike the Xbox which just uses a straight NAND chip.

I need to read up on the technical aspects of the N3DS it looks like. I am new to the scene but I would like to know more about the hardware. Is there a good place to start here?

Thanks, this will be great to check out.

I only use JRunner as its easy to back up multiple Nands and compare the files.

ill have another go tonight at getting it to boot, scared the hell out of me haha

 

[kelroy]

Metaljay, you fix your problem?

 

[metaljay]

Nope, I couldn't get it to boot no matter what, sent it to gamesquest1 this morning haha
I didn't flash anything or read the nand so it must be the cables...

Awhh Damn I am so sorry to hear that I hope everything is alright

 

[kelroy]

Bad news so. Maybe the jrunner isnt the best choice for make the nand backups.

Haha, maybe if it was built for the 3ds , I own a nandx, to bad it was the only part that I successfully soldered into my xbox, I ended up ripping out the cr3-pro...

I use win32diskimager.
