Theres still a greater chance of bricking the Wii when trying to do the above method. Don't play Metroid Prime if you have a PAL or NTSC(J) Wii and are afriad of semi-bricking or adding extra channels. But telling someone to unplug their Wii during a firmware update is just plain stupid.

The Quote below should say enough:

What does interupting the update do?
We arent sure yet, and no-one knows for sure until, and if Nintendo take action. In the past, many users have turned off their power when updating (whether intentional or unintentional) and they have been able to update at a later stage without any problems.

They say themselves they don't know what actually happens when disrupting the power during updating firmware. Even tho many users have disrutpted power during the update and have had no issues. What about the users that have done this and had problems?

So why the hell do it and take that chance?

Dear larrylje,
I have more than then year experience in firmware programming And I can tell you that every company will tellyou not to turn of the machine during the update.
1. When one piece of software is updating the firmware it recreates what is called the boot region of the main firmare. that serves to start the firmware. And this operation is done one millionesime of second compared to the complete update update time (time that is mainly used to copy files and other resources from th source), any good programer will first backup the boot record of the piece of software in other memory zone and so the probabilities that a disaster happen is very low. But companies will tellyou don't turn of the hardware to avoid complications with moorons that will panic when at the reestart of the unsucessful the system will ask: Last update try was interrupted, Do want to reestart the uptate from the begining? Y/N

To make it easy for you:
any piece of software is like a secuancy of numbers that start by 1 :
Example:
Old Firmware:
1a-2-3-4-5...

New firmware:
1b-3-5-7-9...

the only important numbers are: 1a and 1b.(main point of entrance: boot record)
So if you want to replace a firmware by another you have to do:

- Copy the -2-3-4-5... sequence in a sure place (1a still points to it)
- Copy the -3-5-7-9... sequence into the memory
- Replace 1a by 1b and make it point to "-3-5-7-9" sequence (very very very small time)


So my friend larrylje, Don't panic and let people that want to help, try to help.

Excellent post on the concept of firmware updates. Found it very interesting. One thing that I didn't really get clearly out of the post though - do you think it's OK to pull the plug during an update? Sounds like you do (since technically 1a is still pointing to 2-3-4-5, I would have thought 1b is copied over too along with 3-5-6-9 and then just replace 1a once all the copying is done, but a topic for another discussion), just wanted to be sure.

FYI, I've pulled the plug during the MP3 update to avoid the dup channels and it worked for me. I believe Nintendo's programmers aren't clueless and wouldn't write over the old firmware until the new firmware is fully loaded onto the Wii.

I think that probabilities show in this case that its works.

And I want to play my pal backup of Super MArio Galaxy. But my pal Wii is running 2.1 and my Wiikey as it game. Should I update the wiikey to 1.9G before booting SMG, and do I have to let SMG update the wii, or can I brickblock it? Does it need the update to play?
I've got the pal SMG and a pal Wii.
