I use an Old3DS with 11.3 and I downgraded it to 2.1, I'm following the steps on 3ds.guide and when the guide asks me to put the url http://2xrsa.3ds.guide, the console freezes, it shows the white browser interface, the botton screen glitches for a second and then it just freezes, I've tried initialize data but it didn't work, they told me to press select and A, I did it but nothing happens, it's still frozen, I've checked my files and everything's all right, what should I do?
