*** THIS TUTORIAL REQUIRES TWO SD CARDS *** Introduction What's Themehax? (For those who've been living under a rock.) Themehax is a special homebrew entrypoint that is 100% offline when installed, and is 100% Usually successful. Ok, but why does it sound like something bad will happen to my theme? Due to how Themehax works, you will lose any custom (or stock) theme you are using. This tutorial aims to bypass that restriction through the use of two SD cards. Why exactly do I need two SD cards? One SD card is used for the Themehax exploit, while the other SD card is used for storing your Custom Theme (additionally, I recommend using this SD card for most of your homebrew + normal storage.) How does install Themehax? See following section Installing Themehax Before you can have your cake, you must install Themehax! 1A. Download the latest boot.3dsx from Smealums website. Direct link | Page link If you have never installed homebrew, please follow the Page Link and follow all of the directions. Additionally, read about browserhax here 2A. Download the compiled Themehax installer from yellows8 Github, here and place it onto the SD card that you want to use to BOOT into the HBL. If you do not already know (or you are new and didn't read the Page link, and browserhax link on 1A), you put files into their own directory, and place that directory into a directory called "3ds" on the root of the SD card. Example path: /3ds/themehax_installer/installer.3dsx 3A. Run the browserhax exploit to get into the HBL *** MAKE SURE YOU HAVE THE SD CARD YOU WANT TO INSTALL THEMEHAX ON INSERTED INTO THE 3DS*** Install Themehax with the Themehax installer Installing A Custom Theme 1B. Install Custom Home Menu Manager 2 (Or 1, although 1 is depreciated, I prefer it's minimal text interface over 2's buggy GUI.) CHMM 2 Link CHMM Link 2B. *** MAKE SURE YOU DO NOT HAVE THE THEMEHAX SD CARD INSERTED INTO THE 3DS *** *** THIS IS WHERE YOU USE THE SECOND SD CARD *** Use CHMM/CHMM 2 to install your theme into your SD card. Launching HBL 1C. Whenever you want to launch the HBL, insert the Themehax sd card and hold down the left shoulder button while the 3DS loads the Home Menu. Once the HBL has launched, hot swap your SD cards If at any time you return to your Home Menu, the Custom Theme will be applied. Side Notes If you boot with the theme SD card inserted, your theme will load. If you have boot.3dsx on both SD cards, you can run Homebrew (and return to the HBL) on both SD cards without re-running the Themehax exploit. (This only works on Homebrew that exits to the HBL.) *** YOU DO NOT NEED TO RESTART AT ANY POINT, REGARDLESS OF WHICH CARD WAS THE BOOT CARD *** *** THE HOME MENU LOADS THEME DATA EVERY TIME WHEN LOADING / HARD RETURNING TO HOME MENU *** Enjoy having your cake, and eating it!
