With the Wii U launching this past Sunday, the mandatory firmware update is leaving some customers with a brick console. Due to the slow installation time, customers would reset the console before it was completed, thus causing the Wii U to become a giant paperweight. The update is a big one, with it requiring almost a GB of storage space.
This isn’t exclusive to only the Wii U. There have been many reports of PS3s and Xbox 360s bricking during a bad firmware update. Microsoft has even been reported to offer a new Xbox 360 console and a 1-year Gold Membership to those who are unlucky.
The lesson here is to never reset during an install. The crappy thing is that you’re screwed if you accidentally unplug the console or are hit by a blackout when that’s happening.
