I am pretty sure the SD card slot on the 2ds is bad. I’ve put different SD cards into it. It always says that the card is write protected. I know that its not. Is there a way I can fix it? I read somewhere that maybe the arm inside the SD card slot for write protection is broke but I can’t find anything on how to fix it or how to replace the whole sd card slot if I buy a new one to replace it. Thanks.
The fix for this problem is simple. Do you know what SD stands for? Secure Digital. The little yellow or gray slider on the side of you memory card enables or disables the write protection, thus, you get your error. When you put the card in, it slides it down and stops the card from writing. To fix this, take a little peice of tape and cover the slider while in the up (unlocked) position. This will prevent it from sliding to the locked position. Be careful not to cover any of the copper pins on the SD card with tape!
I too had this same issue after my son had jammed his SD card into the slot backwards. When this happens it bends the switch for the SD card write protect in the slot. Its not the card that is the issue but the slot itself. If you look into the sd slot you will see this switch. It looks like a tiny half paper clip shape. It is on the right side of the slot when the 2DS is laying on its back. All I did to fix it was reach in with a very fine 1mm flat head screwdriver and bend the switch up a little bit. The switch was bent down so the card was always reading as write protected. After I bent it up, the switch would fit into the proper gap on the card when the switch was not in write protect mode and therefore the 2DS would see the card as not being write protected. This fixed the issue on my 2DS.
My 5yo pushed in a SD upside down and it bent the WP pin beyond repair. Nintendo uses Mitsumi CIM-J44N slots. these slots have normally open type contacts for CD en WP. http://www.mitsumi.co.jp/latest/Catalog/… so if no card is insterted, or write-protected, the contact is open. Since the pin was heavely bent (in my case), there was no repair possible to the pin. I pulled out the pin, and buzzed out the motherboard. The WP (write protect) and CD (Card detect) lines have jumper pads on them. So i just put a solder blob on the WP line jumper, and now it always reports as not write-protected. (who needs WP anyway?) Quick and easy fix.
I am having the same exact issue with my sons 2DS, but the motherboard in this unit does not look like the pictures above. Im afraid to put a solder somewhere that may just bork the board. The board in this unit actually has arrows and boxes pointing to text, Im guessing marking what each jumper does? Where you circled on your board, it does not look the same, but the text where the box points to is labeled C155 DA4. Would it still be the same place to put the solder to disable the write protection?
The WP pin of my sister’s 2ds broke and i don’t know how to fix it since the motherboard does not look the same as the picture above. I’m kinda stuck with that. Appreciate any type of help!
It’s dark in there and I cannot find a torch Unless I use my phone
