I went to turn on my Wiiu and saw that there was an update to be done, I left it on doing the update, after a few hours it got stuck at 99% and wouldn't come out of it. I turned off the wifi and nothing, I had to turn off the console. When turning the console back on it started to freeze at random times. I thought it could be the NAND so I did the procedure with the raspberry but even on the recovery screen if I'm not fast enough it crashes there too. Has anyone ever experienced this?
