Hi , I bought a wii u recently ,I came home installed and downloaded the update without any problems but then when the system restarted , I was asked to make mt NNID and every time i reach the mii maker part the gamepad freezez and makes a buzzing sound I tried this multiple times but it always gets stuck at this point .
You might need to contact Nintendo in Spain and ship it back to them for repair. You might be able to contact Nintendo UK if that is easier language wise. I can't think of any way for you to resolve this by yourself if it happens the same every time and occurs each time you try the ID setup.
I have sent around 3-4 emails to nintendo of Spain they haven't replied back .... Also when I tried calling them their prerecorded message is in spanish only ..
Well as soon as enter any alphabet in the mii maker the wii u gampad freezes and makes aloud sound but when when I press tv the tv control option on the pad I can control my tv and the touch screen works, I think it's software related
