Nintendo 3DS XL Motherboard Replacement
This guide will show you how to replace the most important part of your Nintendo 3DS XL, the motherboard. The motherboard is the central part of your device, it's where everything happens!
-
-
Loosen the two #00 Phillips 4.2 mm-length screws located at the top of the back cover.
-
-
-
Hold the device so that the cover is facing up.
-
Using a plastic opening tool, pry off the cover starting at the top right corner.
-
Hold the edge of the cover to ensure it does not reattach.
-
Look for the small section below the stylus compartment. Pry off the cover at that point if it is still attached.
-
Take off the cover of the device and set it aside.
Note that on the lower side (opposite to the hinges), there are small hooking tabs. These require you to lift the top (screw side) off towards you, then the lower area.
-
-
-
Insert the plastic opening tool into the opening located on the right side of the battery.
-
Pry off the battery from the lower casing.
-
Lift the battery out of the case and set aside.
My 👴 grandpa was helping me 🔧 repair my 3ds xl and ⚡️electrocuted himself with the 🔋battery while we was taking it out with a 🔪 knife. 💀 Rip grandpa 😔

Using tweezers pull out the rubber bumpers that are located at the top of the device on either side of the game cartridge compartment.
I found that the rubber bumps don't move easily, you'll likely have to use a lot of upward force to move them.

I torn one of the bumpers because I used a needle instead.
You do have a pry a bit. I tore one a little but not that big of a deal.
try twisting upward

My 3DS XL is so old that the rubber bumpers were very hard to remove.
So I tried to heat the rubber bumpers a little bit with a hair dryer for 15-20 seconds, with some pauses every 5 seconds in order to avoid overheating or damaging something as a precaution.
It worked well to remove them but the only drawback is that as my rubber bumpers already got damaged and scratched because of my previous attempts without heating first, heating it up after aggravated the scratch damages when I used tweezers.
So I would recommend heating the rubber bumpers moderately first and be gentle when using something that could scratch or damage them.
(Do not take my words for it, it may not work for you)

I was able to remove mine that were being very difficult with some dull tweezers. I used dull ones because I didn't want to scratch anything. First I wedged it between the plastic and the bumper, wiggled it a tiny bit, pulled it out, wedged it again in another spot and continued this until I got it out with my fingernail. Neither the bumper nor my shell were damaged.

Remove the six 6.2 mm screws using a Phillips #00 screwdriver
#000 ifixit philips screwdriver does not fit the 6.2mm screws. Whats the deal?
I have a 000 Phillips from tekton and it worked just fine.
Megan -
I stripped a good #000 screwdriver, and found that EVERY screw actually fit perfect and snug with a #00 screwdriver. Zero damage to the screws or the screwdriver with the #00.
I bought and used the #00 screwdriver, and it worked perfectly for this.
I had also bought the #000, but I never needed it during the entire operation.

All 6 screws are exactly the same so you don't have to worry about mixing them up.
One of the screws in my 3ds XL seems to have its '+' engraving worn off, i can't seem to unscrew it, though the other 5 unscrewed properly. What should I do?

I stripped a screw in my 3ds xl and don’t know how to get it out. Do I have to use a drill or is there another way?

Remove the 2.3 mm screw located above the game cartridge slot with a Phillips #00 screwdriver.
between these two steps, the bottom two screws are not mentioned. make sure to take those out too ;)
-
-
-
Make sure the SD card has been removed. With a plastic opening tool pry off the lower case starting at the bottom edge and working around the perimeter.
-
Two ribbon cables connect the case to the circuit board. Be careful to not pull the case too hard and rip the ribbon cables.
Make sure that you have removed your SD card, otherwise that'll keep you from completing this step.

Remove the ribbon cables located underneath the left and right bumpers by prying up the base of the cables with a plastic opening tool.
-
Completely remove the lower case from the rest of the device and set aside.
Thank you so much for pointing that out, it was keeping my system from starting up and I thought I blew it!
Yup, that is definitely an upside-down IR board, and will result in a silent post error. It was driving me crazy trying to figure out why the system wouldn't start up.
That's it!! Thanks so much!! I've tinkered around about one month and couldn't get this thing to work...all because I've followed the guide here and looked the picture up twice so I don't put the IR-Board in the wrong way...
Thank you guys so much! I followed everything faithfully and it was DOA on startup. (Black screens, blue light). The IR board was backwards. These pictures need to be fixed. As-is, it shows a broken 3DS.
You should always work on the device in a 3/4 open position- this allows the ribbon cables to have slack and will less likely tear, and is the only position the hinge pin can be removed or installed as it is keyed
-
-
-
-
Position the device such that the game cartridge slot is located at the top.
-
Locate the circle pad on the right side of the device.
-
Remove the two 7.5 mm screws on the upper left and the bottom right corners.
Careful you don’t lose the little washer on the circle pad stem. It’s not held down by anything.
-
-
-
Using a plastic opening tool pop off the circle pad joystick.
-
Do not use excessive force with the plastic opening tool. There is a ribbon attaching the circle pad joystick to the motherboard that will remain attached.
I found it easy to put my finger ontop of the board and apply a little pressure. When i popped off the board, my finger stopped it flying off.
I made a small mistake by popping the circle pad joystick and it went flying off and now im stuck trying to put it back in
-
-
-
Using the flat head side of the spudger carefully lift up the retaining flap that attaches the circle pad ribbon to the motherboard.
-
Remove the ribbon and circle pad joystick.
The 'flat head' holds it in place when down, and you can reattach your ribbon cable when it's up, it only needs to be partway in so when you close the flat head, if your joystick board can't move easily in place then you've done it right, it it's too loose, try again to work the ribbon cable under.
jconnell85 - 답글
The ribbon goes into the left side of the "flat head" right? Not the end that clamps down on the right? I'm having a !&&* of a time sliding the end of the ribbon into the little space between the flat head when it's up and the side of the terminal.
For those of you like me, who got stuck after the last step.
To understand how to actually remove the circle pad, continue with these steps at 21.
Nintendo 3DS Circle Pad Replacement
Hope it helps those after me. I almost ripped some cabling inside thinking I had to take out the motherboard.. luckily I didn't.
Just as what monk333y said, follow the Original 3DS steps. They are identical and you don't have to remove anymore big parts. The only annoying part is taking out the circle pad.
I broke the retaining clip. It is not very strong and I used a bit too much force i think in opening the clip or pushing it back down. Thinking of using hot glue or something else to keep the circle pad ribbon in place.
Did the hot glue work? I did the exact same thing now im not sure what to do…
When testing the touchscreen, make sure you install the analog. Otherwise, the screen will act erratic. Thought I broke a brand new part. Just a heads up!
The entire top part of my circle pad had broken off, so I had no problem getting the old one out. I actually had more trouble getting the ribbon cable back into the clip, and the new circle pad attached to the stick, than any other part.
That said, this was way, way easier than I expected it to be.

Position the device such that the game cartridge slot is located at the top.
-
Locate the IR board located on the upper right side of the motherboard.
-
Remove the IR board with a plastic opening tool by inserting the tool below the IR board and gently prying up.
One assumes they forgot to take the photo before removal and quickly put it back on upside down (accidentally) for the purposes of taking the photo.
Removing the IR board is actually a completely unnecessary step. It's absolutely fine to leave the IR board attached to the motherboard, it's then one less loose piece to go missing ;)
The reason they remove these "easily loosable" pieces is because there's an order to put the board back together or the 3DS won't turn on. This is for replacing the motherboard, which most of the time you will buy and it won't come with the microphone, volume or IR board. Use your head kiddo. If it's so easy to loose these pieces, you should keep better track of them. We might as well just not take out any screws as well because those are very easy to loose
You should add this note to the other uses of this picture; I accidentally knocked that chip off and reinstalled it upside down. I was referencing the photos for replacing the joystick.
You skipped removing the microphopne.
I agree my 3dxl the IR board is also part of the motherboard and doesnt come off.

Using a plastic opening tool, pry off the Wi-Fi board.
-
The Wi-Fi board will still be connected by a wire and it is not necessary to completely remove it for this step. Simply place it out of the way for this step.
Component on bottom left was taken off, but not mentioned. Not sure what it does it does, and I'm assuming it's unimportant, but I just wanted to note.
The thing on the bottom left in the little black rubber cover is the mic!
Why not just seperate the wifi board from the antenna now while in your hands? You're going to do it later anyway...

Locate the volume switch on the right side of the motherboard next to the circle pad joystick.
-
Using tweezers, carefully remove the volume board from the casing. It will still be attached to the motherboard by a ribbon cable.
As previously commented, in this step the microphone (lower left corner) was removed.
This is done by opening the grey flap, removing the ribbon from the motherboard and then either remove it or just let it sit in it’s place.
In my experience the motherboard will go around it easily.
-
-
-
Using the flat head side of the spudger carefully lift up the flap that attaches the volume board ribbon to the motherboard.
-
Remove the volume board and set aside.
This step proved to be unnecessary. It's perfectly fine to leave it attached, and again it's one less small fiddly piece to go missing.
What if I pushed flap too hard and detached and cant find. Now I unable to secure in. Is there a part for this?
Its is the small grey flap that holds in the ribbon.
-
-
-
Remove the black plastic pieces from the lower left and right hand corners with either your fingers or tweezers.
-
You can also remove these pieces easily by carefully lifting up the 3DS and holding it upside-down. They normally fall right out, but don't lose them!
Does anything happen if you lose them or not, that last part made me a little worried?
You won't be able to attach a lanyard to the console anymore, and the uncovered holes will provide egress to the inside of the console for dust and debris and whatnot, but that's about it

Using the flat head side of the spudger carefully lift up the flap that attaches the two smaller ribbons to the motherboard.
-
These flaps are located on the top right and bottom right side of the motherboard.
-
Remove the ribbons from the flap.
For the first picture on step 17, (the one at the top of the board) what does that cable connect to? My clip broke.
MMM as far as I can tell it looks like it's for the touch screen as it plugs into p13 and is the same plug type as p10, p12 and p17 and a couple others. Could be wrong though :)

Using the flat head side of the spudger carefully lift up the flaps that attach the wider ribbons to the motherboard.
-
Remove the ribbons from the opened flaps.
Had some trouble with this: Not exactly sure why, but when after successfully replacing the screen and beginning to resemble, while reinserting the wide ribbon for the lower LCD (p8) it seems that the white locking clip unhinged itself from the connector, and bent some of the pins. The ribbon now won't fully insert.. Can't figure out if I've somehow completely ruined my 3ds. Mostly concerned about my save data that's not on my sdcard.

Remove ten 3.0 mm screws that are located around the face of the motherboard.
I took a micrometer to these screws, they are not 5.5 mm long.
These screws are 3.0mm long.
Fair warning- the xl shown here doesn't seem to have a microphone, but there is probably one on your board. in the bottom left, lift up the flap that attaches the ribbon to the motherboard and remove it. gently pull out the microphone and set aside. I almost tore out my mic while doing this the first time.
-
-
-
Carefully lift the board straight up just enough to clear the two plastic mounts located near the top corners of the cartridge slot.
-
Gently flip the motherboard over the top side.
Laying it down like this puts too much stress on the ribbon cable. I find it better to release the connector while the board is tilted at a 90 degree angle to the body of the 3DS. Less chance of damage to the top screen cable that way.
Add to this step, during reassembly: make sure the volume slider and wi-fi sliders are lined up correctly with their outer switches.

So I tore this wire is this the visual or something?? Please help
How do you get this cable back in? It is way too short...
Tweezers, steady hand, and a little luck.
When fixing, I can't put the 2 wires in the connector. HELP!
Owen Burch - 답글
Don't unplug this cable. Just leave the motherboard flat and don't move it while replacing the face button(s). This thing is way too hard to get back in.
Engiturtle - 답글
It's hard to put it back but it's doable if you spend a lot of time, it took me around an hour and a half, also make sure you put it well because the first time, it was not fully inserted and the screen was flickering with gray lines so after I reinserted it worked fine.

Does anyone know how to fix the flap on the ribbon because I accidentally removed the whole thing
How do you fix it so it will stop shutting down on start up?

my 3DS XL in turn on, speaker making cracking sound, no display, then power off. is this motherboard issue.
I have the same problem, did you were able to fix it ?
soyeliel -
Hey! I’m not sure if this is any help anymore, but for anyone still wondering: The issue seems to be the speaker ribbon cable assembly. It’s probably torn from the hinge, and needs to be replaced. I had the same issue a long time ago and just replaced it, and it works :)
NICE!Thats a really good instructional guide.
What does the P12 connector actually do? What does the cable go to? If this wasn't hooked up would the 3ds still boot?
Your great
Thank you
I just need to fix the 3D slider bar for my daughter so I can setup the 3DS XL for her. I gave the handheld to her when I was able to afford another one so that we can both play games, but now this issue is preventing full setup on the initial power on cycle since I transferred my account info to my 2DS and it wiped the 3DS XL.
I replaced the upper screen on my 3DS XL and now the image is reversed. How can I fix it?
Hello. Electronic component on motherboard my New nintendo 3ds Xl is broken. (It's name is A6M94AA). Where i may find it?
wonderful guide, at the end I still needed some help but we still managed to get my 3DS XL repaired, thanks a lot
Note: If your top or bottom screen was working before disassembly and doesn't work after reassembly, then it's likely that the connector is loose or dirty or damaged or not clipped or PLACED UPSIDE-DOWN. I had this issue with my Super3DS XL(2015) and it turns out that the reason why my top screen wasn't working after put together, was because I had the top LCD connector upside-down. After I correctly put the connector in, It worked again!

Adric101 - 답글
The official battery replacement guide by Nintendo says the screws should indeed be removed by a Phillips #00 screwdriver, so I've edited the guide to reflect that.
They are actually JIS screws though so they could be stripped by that screwdriver
