However, some of you also mention your system has never been modified.

We'd like to help get your system working properly again.

Even if there's a message on the screen stating not to power the system off, it is safe to do so if the download has stopped altogether.

User Jade Tree In Wind, for example, said that after the PS3 logo was on display post update, the crossbar menu would not show up.

The update also "bricks" legitimate Wii consoles, leaving them utterly dead in the water, a brick of metal and plastic so to speak.

Nintendo's technical support forum is currently lit up with reports that consoles are locking up while downloading the update, and will not reboot when unplugged and restarted; Neo GAF is also listing similar reports, with "non-HBC" Wii owners claiming "bricking" as well."The problem appears to lie with an incredibly shoddily programmed update to boot2 of the Wii," reads this forum announcement on Neo GAF.

Slow or incompatible Internet connections can "time out" and result in the download stopping.

Are you using a broadband Internet connection such as DSL, cable, or fiber optic?
