3DS Error Code 002-0102 – Nintendo back with the banhammer on hack users
Multiple reports started spreading a couple days ago, stating that homebrew/hack users of 3DS are being banned from Nintendo’s online services. The error code 002-0102 impact access to Netflix, Youtube, and the friends list. How Nintendo detects CFW, and the root cause of the bans, is currently unknown.
According to users on reddit and popular Nintendo scene site GBATemp, multiple users of hacked 3DS consoles have been permanently banned by Nintendo. The impact of such a ban is limited access to online services. According to the reports, banned users cannot access online applications such as Youtube, Hulu, Netflix, and this impacts the Friends List access as well.
3DS Error Code 002-0102 – What to do
The error message you get for such a ban is Error Code 002-0102 — that says “access to online services has been restricted by Nintendo.”
Although no specific or official reason has been given for the ban, some users on GBATemp have noted that Nintendo have recently updated their help page with the following message:
Description:
- You receive the error code 002-0102 when attempting to connect online with a game or while using the Friend service.
- Error message, “Can’t access the online service.”
What to Do:
If you are experiencing this error code, your Nintendo 3DS family system has been banned due to unauthorized system modifications, play of unauthorized versions of one or more games, and/or connecting to the official game servers in violation of our terms of service. This ban is effective immediately and requests to remove the ban will not be processed.
Curiously, this page apparently used to say : “If you continue to experience this issue, please contact Nintendo by calling 1-800-255-3700” but that message has now been removed. It’s fair to assume Nintendo have been overwhelmed with phone calls from concerned users, and have decided to make it clear they will not fix the issue.

3DS Error Code 002-0102 – what is the root cause
3DS Homebrew enthusiasts are still trying to figure out the actual root cause for this ban wave. There doesn’t seem to be any obvious culprit though. A few polls have been set up on GBATemp to try and pinpoint if some specific behavior (pirating games, enabling/disabling some options in the console’s settings) might be the reason people get banned, but so far no specific trend seems to be showing up.
Among the things people are thinking could lead to a ban are:
- Using homebrews or pirated content, with the option “send information about the console to Nintendo” enabled in settings
- Playing some specific pirated games online
- Using Fan Translations of games
- Some specific CFW (Luma, Cakes, Corbenik,…)
- The method used to load CFW
- Freeshop usage (or any of its forks)
- Save game editor usage (e.g. to modify Pokemon save files)
At this point though, nobody knows, and this list from user Funkymon on GBATemp sums it up pretty well:
- we don’t know how Nintendo is detecting CFW’d consoles
- we don’t know if that’s the sole criteria for banning
- we don’t know if it’s a single list used for bannings
- we don’t know if the the bans are ongoings
- we don’t know how to prevent future bannings
3DS Error Code 002-0102 – does it matter, and how to avoid it
If you’re using a gaming console for homebrew, you should be aware that you are in breach of the terms of service of the console manufacturer. In other words, you’re using a modified console at your own risk and face being banned from their online services. This is even more critical if you are using the console to access any online service from the manufacturer: playing online, using Friends List, or even the eShop on a hacked 3DS is a breach of the agreement.
Ultimately, how Nintendo detects that you have a console with a CFW is irrelevant. What you actually do with the CFW, whether it is legal or not, is irrelevant as well: Nintendo have determined that your console potentially puts their network at risk, and they don’t want you to do that. As a result, they prevent you from accessing their online services. This should be a known risk for everyone who tinkers with their console.
If you are using a homebrew enabled console though, you have to ask yourself whether you care or not about the loss of online services from Nintendo. It seems the impacted services represent a minimal portion of the 3DS experience.
But this is a good reminder for people who are tinkering with Sony devices as well. Losing access to the Playstation Service, in particular if you are a PS Plus user, could be devastating: it would mean losing games, access to online play, saved data, etc… As a result, to me the conclusion is clear: if you want to install a CFW on a video game console nowadays, you have to be willing to give up on the company’s online services, OR have two consoles and two accounts: one for tinkering, and one for your regular gaming.

Not first.
Thank you for the article, Wololo. Looking forward to future updates.
Wish Nintendo would make more games for the switch instead of this waste of everyone’s time.
I recently joined the gaming laptop super master race, very excited for cemu emulator now.
Also looking forward to Disgaea 5 PC version.
finally you credit properly
What are you talking about, I always credit properly.
Thanks for your comment, TyphoonNeon. Looking forward to future updates.
What are you talking about? Laptops suck for gaming. They’re bottom of the barrel.
lol , gaming laptops are as powerfull as desktops nowadays just more expensive because of compact components
I got MSI Titan with SLI GTX 1070 for around £2200, the1080 models were way over my budget.
I think the Benoit is a bit outdated on the subject.
noteworthy: high end is still worse, except if you use those with a docking station or similar… and those are not like ordinary >laptops<
the mobile version of a 1080 is still generally worse than a desktop 1080.
(what i meant in the last part are notebooks that exactly use the desktop components, but they mostly don't have everything in the case)
others than that they are generally powerful enough for gaming.
I got MSI Titan with SLI 1070 for £2200, it’s awesome. I’d choose portability over extra frames any day.
Currently hoarding peripherals lol.
Who really cares about online functionality when you’re able to run backups? Fair trade I say. Haven’t cared about online with PS3/360/PS4/XOne, and likely never will. Gimme CFW over online any day.
I agree, having both would be ideal though.
Do you know if this online restriction include not being able to use freeshop? This thing is kinda cool.
Not a fan of online service but I really hate how these days, games are shipped without complete content and you have to go online and download free or purchase DLCs.
I have the ban and i can still use luma updater, freeshop, and still access the eshop.
Thank you black_squirrel for confirming.
Pokebank
There is a free version of the PokéBank that doesn’t use any online services and is completely offline and stores everything on the SD Card.
Does this just ban your 3ds or does it also ban your user account as well? My concern is that I have a hacked 3ds and wondering if this will affect my account for my Switch?
Does not stop me from installing Cias lol. If I even cared I would just keep one not modded.
(Fellow commenter from GBATemp here)
So far the only ban we’ve seen is a console ban, we haven’t seen any NNID bans stemming from this wave yet. So your switch is safe for now, if they pull out the NNID bans, then it may possibly affect the Switch, but the previous NNID bans (from Pokemon) didn’t affect the Wii U of banned players, only their 3DS.consoles.
Simple solution to not get banned:
Don’t go online.
BAN BAN Yeah good Job Nintendo. BUT i don´t use Online Cra*p … I Love usefull Homebrew and sometimes pirate a game to test before buying. Simply don´t use Online Services, block all traffic and open only the good ip/ports ex. for FBI and and and … Good to Go, Homebrew Never Die!
Good. You dirty pirates have finally been punished as you should have been years ago. I only wish Nintendo remotely bricked your illegally hacked 3DSes as well. Maybe they will yet, and I’ll laugh when you sue only to be arrested for hacking which is illegal worldwide.
Not sure if trolling…. but to heck with it.
Remotely bricking the hardware would be an illegal act committed by the manufacturer regardless as to who it was. Such an act would require the manufacturer to compensate the people affected by their illegal bricking. It would also ensure a lawsuit from multiple consumer protection groups. Nevermind the huge negative PR that would be created as a result. That’s not ok to do, and you “Nintendo Lawyer” should know that.
Now back to our regular posting….
Personally, I’ve never understood the banning. In my opinion, that should be reserved for cheaters in online games, not just because they ran something that the manufacturer doesn’t approve of. Previously they even banned eShop access, which is just shooting themselves in the foot from a business perspective. This ban doesn’t seem to do this, so maybe they’ve lost enough money to finally learn their lesson about trying to coax pirates to going legit. But they still have a lot to learn about banning everything. (Seriously, if you’re going to ban them, just ban them for that game, not EVERY game. Banning them doesn’t provide incentive to go legit. It gives incentive to avoid detection, and just because they ran something you don’t like doesn’t mean they broke the rules of the game. (You can run CFW and still follow the rules of the game. The ToS not so much, but CFW in and of itself is not a “risk” to their servers, other players, or anything else for that mater.))
Nintendo in particular has some pretty badly designed netcode, that they refuse to fix. They rely on the “trusted client” model too much. (I.e. the honor system. All devices are expected to be trustworthy, and remote attestation is always believed. That’s not a good model when the device inevitably gets hacked.) They’ve had this problem for two hardware generations now, and they still refuse to fix it. (Seriously, get some server side verification already….) Only now with the switch, they are demanding money to play online, without fixing the systemic problems with online play.
Nintendo’s timing for this couldn’t have been worse. Not only is the switch still hard to get, and has very few games available, but with this ban wave, they are setting themselves up for a revenue slump. Why? Because they only “official” way to get unbanned is to buy a new console and create a new NNID. That’s going to take away from their potential switch sales. Nevermind the 3DS has free online, whereas the switch will go paid later this year. Even worse, the 3DS is now completely broken. With the dumping of the bootroms, the 3DS has no more secrets and fixing it requires hardware replacement. Not to mention preventing compromised systems from being able to play new releases. (Something publishers will demand.) This can’t be done and the result still called a “3DS”. Long story short, if it didn’t already, the 3DS now has an expiration date. The switch is a ready to go alternative that hasn’t been compromised (yet), but if you think that the devs at work hacking the thing won’t learn from this, you’re wrong. If anything they’ll be emboldened to make sure Nintendo won’t get anything that could identify a system as hacked. So not only is Nintendo’s timing bad, their alternative is not readily available, their adversaries are going to learn from this, and their partners (the publishers) will soon want assurances that their releases won’t get compromised. If Nintendo doesn’t have some profit decreases as a result of all of this, I’d be impressed.
These company’s are getting what they deserve for being greedy! I should not have to pay the same price i payed for 3 years ago because of using a different system. Talk about milking franchises such as Pokemon ,Mario,Zelda,Smash Bros.Kirby and Lego. If these game company’s cared for the consumers Virtual Console would be Universal the whole idea of using emulators to profit off people is insane. Their is no difference from emulating on a PC and then charging money for a download!!! Same for $ony and taking out the emotion engine out of the PS3 for less money to produce systems. So initially Playstation 2 is emulated to play on a non backward compatible PS3. So paying $20 for PS2 Classics is justified when i already owned it for the PS2 screw that. Then they have the nerve to only provide certain games of a library of 1000’s of titles. Same for 3DS i should not have to purchase a ambassador system to play 10 GBA games and then never give the choice of buying GBA on Eshop except on Wii U. Here’s a funny thought Nintendo maybe i want to play on my 3DS!!!!. I have would have to say the only one i won’t complain about is Microsoft about gaming. Microsoft got their act together when they included some backwards compatibility to the Xbox One with Xbox 360. $ony on the other hand refused and are losing out on a lot of extra money.
Lol. Nintendo can’t remotely brick a 3DS if it’s not connected to the internet. All one has to do is just turn Wi-Fi off and keep it off. Sorry Mr. Lawyer, you won’t be able to get anyone here in court unless they have no sense. You can take your legal garbage and shove it.
You’re an idiot. Modifying a console is not illegal worldwide. Modding a console piracy
nintendo finally grew some huh? f-ing a-holes…
