Wii U stuck on boot screen

[bmwtech82]

First, I tried swapping out the Wi-Fi card, but there was no change. The system still wouldn't boot. So I decided to flash the MLC and SLC titles. That did the trick! The console started to boot again without issues. I've since been able to play games and connect to the internet successfully.

Thanks for the help with this.

Next i'm going to install a Nandaid on the first unit.
