Is Homebrew/Custom Firmware safe? #safe

In short: Make sure all the tools are up to date, don't skip steps, and your system has a low chance of bricking.

There always comes a risk when hacking video game consoles. A mistake anywhere in the process may end up forcing you to update (which may hinder your ability to hack your console), or worse, brick, so it is important to pay close attention to every step and make sure to not miss anything. There is always risk of damage to your console involved when it comes to console hacking, but being vigilant will lower the chances a lot.

That being said, most of the tools used for hacking (homebrew, downgrading, etc) have been tested extensively by various other people, and thousands of others have successfully been able to downgrade and set up custom firmware on their systems. As long as you follow steps exactly as written, the chance of a brick is next to nothing.

Some of the tools used perform checks (usually hashes) before doing anything, which greatly reduces the chance of an accidental brick. For example:

A few things you can do to make sure everything goes smoothly:


How can I use the eShop and play games online without updating? #eshop-games

If you're using custom firmware: usually it's safe to update anyway. If you need to stay behind for some reason (for example, relying on BootNTR that doesn't work on latest version), you can use the same steps below.

You can use ctr-httpwn with access to homebrew. This is included in the Homebrew Starter Kit, and only works on 9.6 or higher, though some versions may not work as expected. EUR eShop only works on 10.5 or higher.

Use the Homebrew Launcher, then run ctr-httpwn and read the text on the top screen. Once done, you can exit *hax (press START then X at the Homebrew Launcher), and then use the eShop or play online games.

If the system is below 10.0, eShop through HANS must be used. The "eshop" icon at Homebrew Launcher (from the starter kit) works fine.


Is System Transfer safe to use with a system that has Custom Firmware? #systransfer

System Transfer can be used safely if one or both systems have CFW. Illegitimate tickets (homebrew CIAs, dumped + converted game cards, etc.) are not moved in a transfer, but the titles and their saves are not deleted.

If you are moving to New 3DS from Old 3DS, you should use "PC-Based Transfer", as it's the fastest method and has the least hassle. The other options wirelessly copy files, including ones outside the Nintendo 3DS folder, which might not be wanted (as CFW files and others might conflict with those on the target system's SD card).

Note you cannot transfer from New 3DS to Old 3DS without calling Nintendo to reverse a transfer. Nintendo Network IDs can only be moved to another system with System Transfer or calling Nintendo.


Will Nintendo "ban" me for using Homebrew or Custom Firmware? #banrisk

It is against the user agreement to use unauthorized software or modifications on the 3DS; doing so risks a ban from Nintendo's online services. That being said, Nintendo has never banned any user from its online services on any system purely for using homebrew or CFW. The chances of this happening randomly are very slim.

There are two known exceptions to this. First is cheating online, either through save edits or "cheat codes". Nintendo does ban users (temporarily or permanently) for players that have an unfair advantage online through the use of cheats. Second is the use of "public headers" when playing games online on certain 3DS flash carts.
