Alright I managed to get 10 MB/s then it dropped to 3 lol but it's reading with my other reader after cleaning up the wires and joints.
hmm sustained 5,5 MB/s using only one data line now ^^
I'll update my main post with my findings in a bit, but so far i've gotten 5 fulls dumps supposedly.
Here is a picture of what I was trying to explain about D0-D3

i've worked with BGA chips before just reporting my findings is all. You might want to re-read my post I updated again lol sorry.
yeah i would test mine but im waiting for an excuse
...........i also dont *want* to be first to test it out, i would be surprised if they still haven't done anything to prevent downgrades
yeah i would test mine but im waiting for an excuse
so im guessing this would be the pinout for the n3ds normal size.....(minus the clk point ....and ground, but ground is easy to find
)
yeah i was looking at that point but on the XL you can see a trace going from the point in that position going to the nand, but from what i can see on the standard there is no trace from that point to the nand.....so idk....might work, but i didnt want to just throw a point on there because it looked similarI think were looking for this:
Why do you have GND connection on the other side of the motherboard? Could you not use the cartridge metal pin connection as GND like with previous models?
Either way, it's great to see n3DS NAND mods finally being possible. The best nintendo could do to prevent this is to simply not provide the "test pads". But I have a felling they need them since they probably use them to load the NAND at the factory and for the repair process. They might try and phase it out in the next generation successor to the 3DS but I don't think they'll go out of their way to do that. They'll focus more on preventing exploits from showing up. If they can do that, NAND mods won't really have any purpose.

im planning to make a bunch of pinouts for all models and make all the points colour coordinated for easier referencing
you should be able to see the NCSD at 0x100 to confirm it was dumped correctlySo the reason I chose that GND was out of sheer convince and I don't like applying any more heat then I have to on the board, i.e. on metal shielding because it can soak a lot of it. The pin is outta of the way from any major chip so I didn't need to to route it and it's another wire I didn't need on the reserve side.
On the note of test pads, that is not likely going to happen. These board get made and special jig are made to test all the logic, and components, I'm sure boundary scans are done as well. Also the boards are still hand inspected and tested I assume because they have scribbled markings on them in marker.
I am just glad to have the older information to work with so I don't have to remove any of the chips myself, but having a logic analyzer can be quite useful even when you don't exactly know what you are looking.
I have one from the MH4U and interestingly it was only dumping files that were 1.2GB so something is wrong there, same board but different memory module, using a Samsung one. I hope the red one the gf has a different board as well, it'd be nice to get info for all of them out there. I am considering updating my N3DS and then restoring the NAND but first I am going to try to inspect the files and make sure they are not all FFs or something silly...
oh, that post was in regards to the standard n3ds, not the XL/LL, and yeah i think the pinouts on 3DBrew need updating, they still dont have the 2DS pinout on there, and it would be good to get them all universally the same in terms of colour coding, i always use black = GND, red=CLK, Green=Dat0, Yellow=CMD with the wires i use for the SD reader, so i would like it if it was along those lines
hmmm yeah i heard the nand size is 1.2GB....strange, check the free blocks on each of them, im assuming they probably dont use the extra space but just got the 2GB chips cheaper
