If you are using Windows, right-click the rxtools.rar and open Properties. If at the bottom, it says the file is blocked, check "Unblock" and Apply. This should take care of any problems you have with the following steps.
Mac users: If you're having problems running rxtools (black screens, Installation Suite errors, etc.) try extracting the rxtools zip using a reputable .zip extractor or a Windows PC (or virtualbox).
Backup and delete any "rxtools" folder that you may have on your SD card before doing the following steps!
1. Put the "rxtools" folder on your SD card root.
2. Run cdn_firm.py in the "Tools" folder. It will generate a
firm folder in the same folder that cdn_firm.py is in. The firm folder must go into the rxTools folder like so: SD:/rxtools/firm
3.
If your 3DS is below 7.x firmware: Get "slot0x25KeyX.bin" (Hint: google it, download link should be in the description of a certain youtube video
) (MD5: 817FD1BFFBA60F79CF8CDF19CAF28923). Put this file on your SD card root.
For ninjhax users, you also need to get the "rxtools" folder (found inside the ninjhax folder from the rxtools zip) and put it alongside your other homebrew apps, like FBI.
Part 3 - Launch rxTools for the first time!
To launch from the internet browser: boot up your 3DS
Open your 3DS internet Browser and go to
https://dukesrg.github.io/?rxTools/sys/code.bin (you should bookmark this. To do so, turn off your WiFi, then attempt to connect to the URL. It will fail; now you can open the browser menu and bookmark it.)
If it fails or gives you an error, click the wrench icon and clear cookies and history before trying again. If that doesn't work, clear all save data as well (should be at the very bottom of the browser settings).
To launch from Cubic Ninja, start the game and go into the QR option to boot the homebrew launcher. Select rxtools!
Hold L when the bottom screen glitches to get into the menu if it is sending you back to the homemenu!!!
