The best way would be to bypass/spoof the firmware update to allow games updates but i don't know how to do that.
No error message ? I got "Race attack failed :(" like 10 times then it worked.
Try to run the exploit using MrRean's files ( https://gbatemp.net/threads/how-to-run-the-kernel-exploit-on-your-wiiu-tips.395335/ ) then http://wj44.bplaced.net/py, it worked for me.
I think your kernel exploit payload doesn't work for me, I just tried using the one from MrRean's thread and went to http://wj44.bplaced.net/py and now i can connect, i'm getting this error http://i.imgur.com/1tSlSD9.jpg but when i click on continue it's working !
http://wj44.bplaced.net/osdriver worked
http://wj44.bplaced.net/PyGecko2 worked
Ping request to my Wii U works fine too, but still can't connect using TCPGecko :/
It's not the movies or games downloads that I would worry about, like breaking into networks, downloading encrypted things, spying on network traffic. I have seen so many "Top Secret" seals on files when I was a kid
I was obsessed with finding UFOs, a surprising amount of US files where stashed on computers in other countries, China back in the early 90s omg sooo much
