To downgrade, I tried it like 7 times and it get stuck at "HAX INT". I even opened up menuhax and ftpbrony and I get the same results. Do I sysupdater or safesysupdater instead? I remember when I did it with my O3DS, it took me one or two tries.Do you mean to open the the tool or to actually downgrade ? From 3 times that i used it to downgrade, it worked 2 times on the first try and one time i had to do it twice.
