    Hello Temp!! Hope Someone could help me! Accidentally broke CMD Pinout by pulling my mod with a really badly pulse... if someone could say me if there is another pinout where I can put the mod or where can I scrape to uncover the copper and solder... please!! I tried to downgrade it and got a Brick, can't enter in Recovery Mode, fortunately I've made this mod and backup my NAND.... but now this is my problem... T- T Thanks in advance

    EDIT: Forgot to mention this is a 3DS XL... I'll upload some pics

    EDIT 2: Sorry for the post on a wrong place, can some moderator move to the right place, please

    EDIT 3: Some pics:

    Just by looking at the PCB looks like this should be an alternate point.

    yeah... but I think that this pic is from a N3DS :S mine is an O3DS XL :S can't find something like that on my MOBO x, x

    Oh sorry, misread. Looks like the 3DS XL is a bit tougher.

    Since I don't have a 3DS XL I can't check myself but there should be a solder point on the other side of the pcb.

    You need to find THIS point on the other side of the pcb and trace it to a point where you can solder.

    Edit**

    From what I can make out from some images it looks like the point should be this one below. I can't make out from any pictures if there is a trace going from that point to the resistor, but if there is a trace you should be able to use the side of the resistor closest to the point as an alternate point.

    Note, I don't have access to the real think so you will need to find the exact point yourself, but if it's not the one in the picture it should be nearby.

    I'm in the same situation as you. I you have found the other point... Can you say me which one is? Thx!

    Ok, I've discover something based on other images, hope you can help me...

    This image is telling me, that CMD is M5 on the eMMC
    [​IMG]

    So, there is no point to connect CMD Pinout to CMD on eMMC... and really can't find it on the other side of the MOBO, here I left an image of what I can find looking very carefully:
    [​IMG]

    EDIT: If MOBOs between N3DS and O3DS are similar... then I can guess that the resistor from N3DS that you've said me first time, is C123 (In Yellow)? Apparently C123 it's the most nearby to CMD... By the way... as far as I know... CMD is used for a response on eMCC? What can happen if I use a wrong Pinout, or if I don't use it, it just won't work?? Thanks for help!! :)

    the only possible point of cmd is under the cartridge slot , i can point you on the o3ds to the resistor that cmd is connected to , but i don't have a o3dsxl without the slot cartridge
    remove the game catridge slot and i'll show you exactly the cmd point(it's the 2nd resistor , top point)

    I'll look for it when I find time then update you.

    Still, I think you should check with a multimeter if any part of the old contact still remains. I can see a bit of solder still left.

    the point that spore2 mentioned is wrong....also don't heat that resistor too much or you can lift it ; better use a smalllllll wire and a thin solder iron

    Thanks for advice, I've destroyed the cartridge... but anyway, I want more to revive my 3DS, later I'll buy one, these are the wires and solder I'm using, should I change something?

    Personally I'd use a thinner wire for the alternate cmd but it should work if you've steady hands. :-)

    Also, I recommend you use some flux.

    sorry for my bad english, with flux, you mean the grease thing??

    look , before starting soldering , replace the borad to the 3ds shell and fix it
    then you can start soldering
    also those wires are really a problem , you can easily remove that little resistor
    and when you are done soldering , fix the wires to the board with a little tape , so you won't remove the remaing solder points

    — Posts automatically merged - Please don't double post! —

    and since you don't have a game cartrifge slot now , you can, just direct the wires from that point to the outside

    Yeah, it comes in different forms but "grease" is one. The purpose is to make the solder "stick" to the copper easier.

    Ok thanks both of you for your help, I'll using phone wire for CMD, and yeah, I was thinking of put right there the mod while I get a new cartridge slot, I'll update when I finish the job, please, whishme luck :P

    — Posts automatically merged - Please don't double post! —

    F***!! I'm starting to think that my solder iron is heating too much... now I need a new CLK Pinout... T- T, I must say that this have never happened to me... and it sad that this happened twice with the same 3DS... T- T
