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 .
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
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 ..
