DS Profile Exploit Setup
Step 1:
Make sure to have the latest Launcher.dat on your internal MicroSD. You will also need to copy the proper mset_xxx.cia for your region (where xxx is your region code) to your internal MicroSD.
Step 2:
You will need to locate a copy of devmenu.3ds and place it on your Gateway MicroSD card. (You will need to use Google or ask a friend for a copy of the application)
Step 3:
Power on your New 3DS and using your boot game, boot to the Gateway Menu. Select the “NVRAM INSTALL” option and follow the prompts until it has finished.
Step 4:
Place the cursor over “BOOT GATEWAY MODE” and Hold B then Press A, then Press X by itself to boot to SysNAND Gateway Mode.
Caution! Do not use SysNAND Gateway Mode except to perform this operation as anything done to the New 3DS in this mode will apply directly to the system itself and could cause damage!
Step 5:
Press Select and choose the DevMenu ROM from the list (You MUST use DevMenu, other .cia installers will NOT work). Boot the DevMenu ROM and Press Right one time to get to the Import tab. Use the Down Key to navigate to your mset_xxx.cia file and press A to import/install it.
Step 6:
When the import/install has finished, press the Home Key, then Close the software. Shut off your New 3DS at this point. The DS Profile Exploit has now been successfully installed on your New 3DS system.
