Hi guys, I have a New 3ds with firmware 9.0.0-20U. I followed step by step to install mset region for activate Gateway mode with the classic System Settings DS Profile method but it didn't get through. Everytime I'm going to Ds Profile, it didn't pop up to Gateway mode . This is how I did: Boot into Gateway menu using Zelda save exploit - Install NVram - Boot gateway mode - Open Devmenu.3ds - Import mset_usa.cia - Reset - Then nothing happened when I pressed Ds Profile. Where Am I doing wrong? Thanks for reading.
