Hello, I'm currently using an O3DS with firmware 9.2 Europe. I'd like to go to 11.2 (since this is the max that gateway supports at this moment) so i can play games like pokemon Moon & Sun. I'm stuck at this since i can't figure out how to do this. Could anyone please help me on this on link me a good guide ? since i've tried several YouTube videos but they didn't help me yet. Thanks in advance !!
