well my friend don't care about online, he just want to play backup and meme stuff. But to use the hack, i need to connect to the eshop at least once to buy the brain age right. In my case, i probably should:
“Run Homebrew Launcher” for the first exploit attempt
and then do this right away to get the ds game?
Blocking System Updates
Note that, to access the eShop with these DNS addresses set, you must first run NNU-Patcher through the Homebrew Launcher. Additionally note that NNU-Patcher is a temporary patch and will need to be ran again if you need to access the eShop after a reboot.
Note that, unless you block updates with this method on all current and future connections, updates on the Wii U are performed automatically and cannot be disabled.
Go to the “System Settings”, then “Internet”, then “Connect to the Internet” then press (X) to display your current network connections
For each of your connections (and all future connections), do the following
Select the connection
Select “Change Settings”
Move to the second list and choose “DNS”
Set the DNS to “Don’t Auto-Obtain”
Set the DNS server IPs to the following servers
168.235.092.108
081.004.127.020
Select “Confirm”, then press (B) to save
These servers will block your device from being updated
