Been following this guide here, https://3ds.guide/installing-boot9strap-(ntrboot) Recently got an NTRboot flashed R4 Gold for my 2DS XL and according to the guide, I need to install 9boostrap, safehax, etc by triggering the magnet and then pressing a button combo. The problem is the guide isn't very clear on whether or not the system needs to be on first, or you press the combo when you trigger the sleep mode, etc.
- Use the magnet to find the spot on your device where the sleep sensor is triggered
- This step is not needed on the old 2DS (which has a sleep mode switch)
- Power off your device
- Insert your flashcart into your device
- Place the magnet on your device to trigger the sleep sensor
- On old 2DS, you should instead enable the sleep mode switch
- Hold (Power) + (Start) + (Select) + (X) for several seconds, then release the buttons
- It may take a few attempts to get this to work because the positioning is awkward
- If the exploit was successful, you will have booted into SafeB9SInstaller
