This is mainly for N3DS rxTools users and frequent 9.0-9.2 sysNAND users. So recently Nintendo decided to pull a maintenance run that effectively stops you from playing online game services like Pokemon ORASXY, Smash and a few others unless you update your system. This tutorial will help you bypass the check and get your online services back, however it will require that you have: A 3DS system with 9.0-9.2 & CFW installed. (Preferably unlinked NANDs.) Alternatively you can use this on 9.3-10.7 & a hax entrypoint using the NASA CIA installer. *WARNING! This method of installation will no longer work on 11.0 and above until a Kernel exploit is found for those updates* A CIA installer (FBI, BBM, ect.) 3DSNUS (Which will be linked here.) Now, onto the steps: Optional but recommended: Before any of this you should always back up your NAND. It stands to reason that at some point during exploiting your console that you will have backed it up, but it's best to do so again now so you can restore quickly if something goes awry. Open up 3DSNUS and input the friends system-module Title ID and Version which is the only one you'll need. (Of which you can find the required one for O3DS here and N3DS here. Select the first link in the "Report" box of your region e.g "E" is USA. "P" is EUR.) Make sure you remove the "v" from the version number and "Pack as .CIA" is checked, then download the file. Now, take the downloaded .cia from the root of your 3DSNUS folder and drop it into where you keep your .CIAs on your SD card. Or if you're lazy you can just throw it into the root of the SD card, but better neat than messy with these things. Pop your SD card into your 3DS system and boot up your CFW by the method of your choice. Go into the .cia installer of your choosing and locate the .cia. Depending on what installer you use, you'll have to choose the equivalent of system or NAND to install the .cia if it doesn't automatically, as SD Card won't work. For FBI, make sure it's set to NAND for install. Once that's done, exit out of the .cia installer, reset your 3DS, open up the CFW again and hop into the affected game. Try out the online services and it should work. Congratulations! Optional: Should your game still not work correctly even after this, it most likely requires the latest NVER (named New3DS NVER in the N3DS) to function. Repeat steps 2-4 but instead download the latest NVER (which can be found in their respective console versions for the above linked system update in step 2.) *If you can't find NVER in the latest firmware list then use this list and check each update before it until you find NVER* You can do this as well in sysNAND but please be careful as making franken-firmwares on sysNAND could lead to problems down the line (unless you have a NAND hardmod,) and make sure you've got a backup of your NAND before doing this. At any rate I'm fairly confident this will not brick your system, however I am not responsible if it does brick. Thanks for this tutorial and it's information go to: @Sgt. Lulz for pointing this out. @Sheimi for testing this and confirming it alongside my own results. @Pixel Eater for providing a link to N3DS 10.5 files for N3DS users. @Domukuro Wolfield for reporting that the 10.5 friend system module has been patched. @cvskid for keeping me up to date on the latest firmware since 11.1.
