I was given a wii u on monday, played it quite a bit in the interveening days, both games on disc and downloaded. Tonight I attempted to sync some wiimotes to the system so that a couple of people could play Mario Kart. These remotes worked fine with both of our past Wii's, they are first party and I put new batteries in a few second before attempting to sync them. After trying for ten minutes to get them to sync they finally connected, then ten second later the LEDs on both remotes went dark. No cursor appeared and pretty buttons on the remotes caused them to simply blink as if they were not paired to a console. I attempted to sync them again but for the first time the console froze. Since then, about 3 hours ago, the console now freezes regularly and still is unable to sync with wii remotes.
I have tried using other remotes, swapped batteris around, disabled quickstart menu, unplugged every cord from the console for 15 minutes, unplugged my router and turned off every cell phone and WiFi Tv in the house. I've eliminated the youtube app, I've removed the sd card that was in the console. Still, loading any app now has a 50/50 chance of freezing the console. If I manage to make it through one app and try to do something with a second one, that one is almost garunteed to freeze. The wii motes still will only connect for a few secondds then disconnect, I have also wiped the previous pairings and tried resyncing them.
I'm going a bit nuts heres. If it matters or helps at all this is also a Wind Waker HD special edition that was purchased brand new and untouched from a game stop on the 28th of july.
Edit: and before I forget, and yes I checked, everything is up-to-date for patches and such,
