    This is THE #1 guide for getting a good boot rate with RxTools.


    Feel free to skip steps you know you've completed, but for this I just did a backup and started from scratch. Messing with my previous setup just caused tons of random issues and my boot rate was pretty low.


    __________________________________________________ _________________________________


    First of all, I'm using Ninjhax (v1), I also have a Gateway and Pasta, but all you really need is access to the Homebew Loader.


    I'm also using a 9.2 3DS.


    I zipped up the RxTools Nightly and Boot.3dsx I'm using. Available here:
    RxToolsHomeMenuHax.7z

    Pre reqs


    Have access to the homebrew loader, have access to internet.


    Backup your SD card


    Have the zip I linked extracted to your SD card.

    Setting up unlinked Emunand


    If you have a Gateway card, remove it


    Open the o3ds web browser, navigate to http://go.gateway-3ds.com/


    You should see the gateway menu, scroll along until you see the Format Emunand option


    Activate this option and wait for it to finish, once it's done, reboot without the SD card


    Go to settings and format your system, it will need internet access but WONT update, so dont worry.

    Installing HomeMenuHax + RxTools


    Setup Wi-Fi on your 3DS (should be in freshly wiped SYSNAND, hax free)


    Go back to the Home Screen and click the upper left settings icon, then choose a theme (even basic red)


    Quickly load up your Homebrew Loader (via Ninjhax or whatever) and choose RxTools


    Follow the onscreen steps to install RxTools


    Reboot


    Quickly load up your Homebrew Loader (via Ninjhax or whatever) and choose HomeMenuHax


    Follow the onscreen steps to install the exploit


    Reboot and hold L (skips HomeMenuHax), go into the 3DS Settings and delete the network settings (so SYSNAND wont update)


    Power off the 3DS, remove the SD card and put it in your computer


    Rename boot.3dsx to HBL.3dsx (or just delete it), rename bootrx.3dsx to boot.3dsx


    Booting into Emunand


    Put the Sd card back into the 3DS and turn it on, while the system tries to load the theme, it'll trigger the HomeMenuHax exploit, which loads boot.3dsx, which (in this case) calls RxTools, which then autoboots to Emunand.


    The first thing you should do is go into Settings and verify that the system version number shows as 'RX-E', that means you've booted into Emunand!


    The second thing you should do is change the Emunand theme+layout, so if you ever accidentally boot into sysnand, you'll know. I have a bunch of folders on my Sysnand, that spell out SYSNAND so I never accidentally update.


    And lastly

    Injecting CIA installer


    reboot the 3DS, when all the HomeMenuHax text first pops up on the screen ('Hello'), immediately press and hold L


    You should see the RxTools menu, navigate to Advanced, and FBI injection. If you attempt to install it to EMUNAND, it'll tell you some information, region and a number.


    In my case the region was eur, and the number was 3077.


    On the SD card, I went to E:\fbi_injection\eur\v3077 and moved the two files (fbi_inject.app, fbi_inject.tmd) to the root of the SD card (E:\ )


    Reboot back intot he RxTools menu, and re-attempt to inject FBI, it should work this time, replacing the health and safety app.

    End


    Thats all the steps, seems like a lot but now whenever I turn on my 3DS i'm in a safe emunand environment, without having to load up and wait for gateway or cubic ninja.
    I also dumped my backup folder into my emunand SD and all my old games, saves etc appeared without a problem [​IMG]

    Is there a way to do this on firmware 4.5?? I have the mset installed so it's not exactly difficult to launch rxtools, but I would love it to autoboot

    I don't think there's no way to do it on that FW which is what I was also looking for. So I ended up installing my FW to 9.2 which worked perfectly after that.

    Did you put the boot.3dsx file on the root of your sd card or did you put the correct boot.3dsx.

    You can replace the rxtools boot.3dsx with the homebrew launcher boot.3dsx so it will auto boot into homebrew launcher. Or you can get CTRBOOTMANAGER which will allow you to specifically select what you would like to load up. You can use this to also load up homebrew.

    the boot.bin you provide makes hack2.5 and the homebrew launcher completely unusable for me. I get a 20% success rate with browserhack and when I launch any homebrew, my o3DS freezes.
