Figured it out, I was doing my router's IP, not specifically my PC.
Got a popup on the Wii U after hitting exploit. Says "verify...". Do I hit "OK"?
for me it started hb launcher after hitting exploit and waiting a little bit. i really don´t know where that "verify" comes from. i used the same zip from the first post. you sure git every files needed on your sd card ?
maybe the OP can shed light into this issue with "verify"
