So in this video Im going to show you how to install custom firmware on your Nintendo 3DS now before we dive in, I just want to mention that this tutorial is for educational purposes. Only anyways, Im Anton and lets get started. First things first youll need a device that can read and write to an SD card. You can use a PC, Mac, Chromebook or even a mobile device, as long as it has a file manager and internet browser, as no applications are needed. Apart from the optional FAT32 format for Windows, this tutorial will work with all Nintendo 3DS systems, including the new 3ds and 2ds series, regardless of region or firmware for this tutorial Ill, be using my new Nintendo 3DS XL, and I recommend getting one of the new systems. As some applications and games will run better, if your system is modded or you think it is, I recommend not proceeding with this tutorial, as your system may get bricked an easy way to check if your system is modded is to hold the select button while pressing The power button, if you dont, see the screen youre good to go now, Im not responsible for anything that were to go wrong while following this tutorial. But if you follow it carefully, you should have no issues as brigging. A 3DS seems to be a rare occurrence. Nowadays, if you have any digitally purchased titles, they will not be affected. Just be cautious when playing online on Nintendo servers as cheating can get you banned.

Every Nintendo 3DS system includes an SD card, either 2 or 4 gigabytes. You can use this one to install the custom firmware, but I would highly recommend getting a larger one, so you can do way more and dont have to worry about upgrading. I picked up a SanDisk 128 gigabyte SD card and has been working wonderfully. You can go larger, but 128 gigabytes seems like the most practical and they are pretty affordable too make sure you buy a notable SD card brand and that it has a fast read. Speed such as 120 megabytes per second as loading times may take a while, if its too slow and may even lead to some crashes, so dont cheap out on an SD card, as it will make your modding experience way better and will be worth it in the Long run also make sure that you are using the correct SD card type for your system, whether thats a standard or micro, SD card and be sure to have an adapter if youre planning to use a Micro SD card for the older 3DS systems. Next make sure your system is updated, head to system settings and, of course, to do this. Youll need to be connected to the internet and the firmer version should be listed on the top screen to update date, select other settings and then move right four times and select system update, press. Ok, then press. I accept on the terms and agreement screen, press, ok and now it will update press.

Ok once finished. It should be at 11.16.0 49, but if it has been updated past this check the pin comment or the description to see if the tutorial is still relevant. Now, if youre using the SD card that came with your Nintendo 3DS, you can skip the section, but if youre upgrading to a larger one, please follow it as we are going to be backing up all the files. But you dont need to if you dont care about the data on your old SD card and want to start fresh, alright, so now its time to remove the back plate on my new Nintendo 3DS XL and remove the micro SD card, depending on the type of 3Ds you have, it may be easier to access next Im going to plug it into my adapter and then straight into my PC. Once its open youll see a Nintendo 3DS folder, but you may even see a DCIM folder if youve taken any pictures now create a folder and name it, something that youll remember Ill call mine3ds, backup now just simply drag and drop the folders into your folder. Now inject your stock SD card and insert the one youre going to be upgrading to now. The SD card needs to be formatted to font32 for the 3DS to read it. If it is xfat or anything else, it will not work so for Windows. We are going to use Font 32 format, which you can find on my website in the description, so simply select what drive it is based on its letter and then press start make sure you have the correct letter selected as formatting a drive will erase all data From it so be careful, as you probably dont want to erase your entire computers hard drive, I also recommend closing all windows to avoid any potential errors.

Now, if you are on Mac, you should be able to format it using Disk Utility now, just simply drag and drop your backup Nintendo 3DS folder into your new SD card, and everything should be copied over once its finished close the program, and now our SD card Is ready to go if you are using the SD card included with your system, just connect it to your PC and if you follow the upgrade process, your upgraded SD card should now be in your PC so head down to the description and go to The Homebrew 3Ds page on the anti metro website, so click download and then click on one of the links as there are multiple alternatives. This will bring you to a download page and all you have to do is press download. This will download the Anton Metro, 3DS boot. 9. Strap 2023 package, which will include everything you need and does not contain any copyrighted files once its complete extract, the folder, using whatever program you prefer once everything is extracted, go ahead and drag and drop all the files onto your SD card.

This is an ID code that gets assigned to every Nintendo, 3DS SD card right click on it and then select properties.
