I finally made it! Thanks guys, ur awesome. I tried every Delta, specially 2, but had the "page too big" error. Then I connected to my phone's wifi (my mobile phone) and then tried a lot. Then it just keep freezing. Then I moved from the SD card all what wasn't needed and after some attempts (not many, 15 or less) it worked. It worked first on main exploit link, but I took away the hbl folder. Then I moved it again to the SD card and tried till it loaded. Now I have haxchi installed. Also on the exploit link. I bought my Wii u account like two months ago, and I could download Dr Kawasima for free. At first it showed like It costs 6,99€ I think, then I clicked on download and it downloaded.
