Ah crap. I guess I have to buy this then. Cheers.

What about technique wise?

sorry, i'm not really the best solderer, my hands can be a bit shaky, i would never want to do work for anyone else, just watch some youtube videos and practice on old stuff really

Solder attaches to solder. So put a bit on the pad your are soldering to and on your wire and you are good to go. Having a steady hand is also helpful.

where is exactly the cmd pin in a classic nintendo 3ds?
gw3ds kills my console and I am trying to restore the nand

Please refer to this thread for the classic Nintendo 3DS.

Is there an alternate point for the CLK on an XL?

No, cut the trace

Where? Not sure how I would be able to remove the epoxy without damaging the chip.

Just gently scratch the yellowish epoxi. I did this mod in a XL that a different technician tried before. He stopped after he pulled the CMD point.

I did like this and was able to recover:

Good luck!

EDIT: fixed the image!

top tip! use the edge of your nail and just keep rubbing along the edge of the chip until it breaks away,then you can pick it off easy enough, better than risking using a knife or something like that, unlikely to damage anything with your nail

Good one!

I did several of this mod so far using the 4 wires micro USB connector and my avg read/write speed are around 5mb/s using only DAT0.

Is it possible to boost read/write speeds by using the other DAT lines?

Thx.

yeah from what i have read it gives around 15-20Mbs iirc with the extra /dat points connected
personally i would hope people wouldn't be reading and writing their nand often enough to need the extra speed

Well, this is a mod you shouldn't use that often, so I hope too.
It's just for personal knowledge.

Thx for confirming!

 

[Woodie]

I did micro usb mod,too.
thx for tempers.

Off 2ALL: I have an idea which may make downgrade possible. I need some of your help, so if you have a NAND-adapter soldered and/or Gateway please PM. It won't involve your system flashing.

I have an idea, too: why don't you just tell us what you're trying to do? Less effort for everyone involved.

Well, the main idea was that the unique per-unit key used to encrypt NAND partitions is not changing with the firmwre update. And this appears to be true, so we can transfer changes of partition data from 4.5 to 7.1 or vice versa. But I had a conversation with Yellows8 at 3dbrew.org and he confirmed that some console-unique AESMAC initialization data stored on encrypted CTRNAND partition is changed during system update. In that case AESMAC will initialize with the wrong value and boot will fail.

So in other words your idea doesn't work?

Also, I'm looking to perform the Nand Mod on both my 3DS and 3DSXL. The micro usb mode seems awfully cramped to solder. Is there a better connector port thing that I can use in place that would be easier to solder?
