You're sitting there with a handheld that’s basically a time capsule of 2013, and honestly, it’s acting like it. Maybe the buttons are sticky, or perhaps the software just feels... heavy. People always ask how do you reset your 3ds when they're getting ready to sell it on eBay, but there’s actually a lot of nuance to it that most "how-to" sites skip over entirely.
It isn't just one button.
You’ve got the soft reset, the hard factory wipe, and that weird "Recovery Mode" that feels like you’re inputting a cheat code just to save the hardware from a frozen screen. Most people just want a fresh start. But if you do it wrong? You lose your StreetPass data, your Mii characters, and those digital games you bought before Nintendo shuttered the eShop. That’s a digital tragedy.
Why Most People Mess Up the Reset Process
The 3DS is a finicky piece of kit. It’s not like an iPhone where everything is magically in the cloud. Nintendo’s infrastructure for the 3DS era was, to put it lightly, a bit of a mess. When you start wondering how do you reset your 3ds, you have to distinguish between a "System Format" and a simple reboot.

A lot of folks think formatting the system deletes everything. It does, but it doesn't unbind your Nintendo Network ID (NNID) in the way you might expect. If you format the system without an internet connection, that NNID stays "linked" to that specific hardware in Nintendo’s database. If you try to log in on a new 2DS or a New 3DS XL later, you’ll get a nasty error message saying the account is already in use.
It's annoying. Truly.
The Difference Between a Soft and Hard Reset
Sometimes your game just freezes. Pokémon Sun or Moon were notorious for taxing the original 3DS hardware to its absolute limit. If your screen is stuck, you don't need a factory wipe. You need a soft reset. You just hold down L + R + Start (or Select). This kicks you back to the game's title screen.
But if the whole OS is unresponsive? Hold that power button down for a full 10 seconds. Force it to give up. It feels a bit brutal, but it works.
Now, if we are talking about a full-blown "I am giving this to a stranger" reset, that’s a different beast entirely. You have to dive into the System Settings. It’s buried under "Other Settings," and you have to scroll all the way to the fourth page. Nintendo really didn't want you doing this by accident.
The Step-by-Step Reality of a Factory Format
Let’s get into the weeds of how do you reset your 3ds for real. First, make sure you're plugged into a charger. If the battery dies while the system is rewriting its internal flash memory, you’ve just made a very expensive paperweight.
- Open System Settings (that little wrench icon).
- Tap Other Settings.
- Navigate to page 4.
- Select Format System Memory.
At this point, the 3DS will ask you to connect to the internet. Do not skip this. This is the part where the handheld talks to Nintendo’s servers to de-link your NNID. If you’re offline, the system wipes the data locally, but the server still thinks that device owns your games. It makes moving to a new console a total nightmare involving customer support phone calls.

Once you confirm, the 3DS does its thing. It feels fast. Maybe too fast. When it reboots, it’ll be like the day you took it out of the box—scary, blank, and waiting for a new owner.
What Happens to the SD Card?
Here is a detail most guides forget: the SD card. Formatting the system memory does NOT securely erase the SD card. It just tells the 3DS to stop looking at the "Nintendo 3DS" folder on that card. If you're selling the console, take the SD card out. Or, if you're including it, plug it into a computer and do a full FAT32 format. Otherwise, some tech-savvy person could potentially recover your old photos or save files.
Troubleshooting the "Reset Loop" and Frozen Screens
Sometimes, the standard "Settings" menu isn't an option because the console won't even boot. This is common if you’ve tried to install custom firmware (CFW) and something went sideways, or if a system update got interrupted.
There is a hidden "Maintenance Mode."
To get there, turn the power off. Then, hold down L + R + Up (on the D-pad) + A. While holding all of those, press the power button. If you did it right, the console boots into a sparse, grey menu that allows you to perform a System Update or a reset without loading the full Home Menu. It’s the 3DS equivalent of "Safe Mode" on a PC.
It has saved many consoles from the trash bin.
The eShop Problem: Can You Get Your Games Back?
Since the 3DS eShop closed its doors to new purchases in 2023, the stakes for resetting are higher. You can still redownload games you own, but only if your NNID is properly linked.
If you reset the console and didn't have an NNID, those games are gone. They were tied to the hardware ID of the motherboard. Once you format, that ticket is deleted. Gone. Poof. This is why collectors are so picky about "clean" systems.
If you did have an NNID, you just log back in after the reset. Your "Redownloadable Content" list will be waiting for you.
Dealing with Parental Controls (The "I Forgot My PIN" Nightmare)
Nothing stops a reset faster than a Parental Control PIN. Maybe you bought the console used, or maybe you just haven't touched it since 2015 and have no clue what four digits you picked.

If you enter the wrong PIN, tap "I Forgot." It’ll ask you a secret question. Forget that too? Tap "I Forgot" again. The system will give you an Inquiry Number.
Back in the day, you had to call Nintendo and pay a small fee. Now, there are "mkey" generators online—tools built by the community—that can take your Inquiry Number and generate a master key to bypass the lock. It’s a bit "grey hat," but it’s the only way to reset a locked system in 2026 without a massive headache.
Practical Steps to Take Right Now
If you are planning to reset your device today, follow these specific actions to ensure you don't lose data or brick the unit:
- Sync your StreetPass Mii Plaza. If you care about those digital hats and map progress, know that they are tied to the system. There is no easy way to "backup" this data to the cloud without a full System Transfer to another 3DS.
- Check your SD card capacity. If you are resetting to fix slow performance, sometimes it’s not the OS—it’s a cheap or failing SD card. Try a high-quality Class 10 card formatted to FAT32.
- Back up your photos. The 3DS camera is terrible by modern standards, but the 3D photos are nostalgic. Copy the
DCIMfolder from your SD card to your computer before you touch any reset buttons. - Verify your NNID credentials. Go to the Nintendo website and make sure you can actually log in. If you reset the console and realize you don’t know your password or the email is dead, you're in for a rough time.
- Perform a "System Transfer" instead if you are just moving to a different 3DS. This moves the "identity" of the console to the new one and automatically formats the old one at the end. It's the cleanest way to do it.
Resetting a 3DS is a bit like cleaning out an old attic. You want to make sure you aren't throwing away the heirlooms with the trash. Take it slow, stay connected to Wi-Fi, and make sure your charger is snug. Once that green light flashes and the formatting bar finishes, there’s no going back.
