Ok so i set my 3ds away for a long time and i'm recently coming back to . It is currently on Ver. 10.4.0-29U. The main problem is that i tried to follow ( https://yls8.mtheall.com/3dsbrowserhax.php ) but when i open my browser it ask me to update my firmware and i know that's a red flag when it comes to homebrew. So my question is should i upgrade my firmware via system update or is there an alternative method to updating to a certain software. If the latter what is the desired firmware version and method to use. P.s if this exact question has been asked can someone kindly just link me to it.
