Wii downgrade theory

[ihaveathumb]

This might not make sense, but here it goes...

A wii get's semi-bricked by updating it with a game from a different region. Now there is a way to unbrick your wii with the semi-brick fix. I'm guessing it forces your Wii to use the firmware on the disc. Now, brick blocker removes updates from the Wii ISO right? So it is obviously known where on the ISO the update is. Couldn't someone take an update from an older game and put it on the semi-brick fix?

Keep in mind I'm assuming the unbricker forces the firmware update. If it doesn't work like that, it completely kills my theory.

Just stop all this nonsense about downgrading!!!!
it's not like taking out vista and putting in xp!

The wii contains all the versions inside!
If you make an update you don't loose xp when you install vista, the wii contains all versions from 2.0 to 3.0, 3.1, 95,98,Me, NT, 2000, XP, 2003 and vista!!!

You understand it now? If a game needs to run on 95 version it will run on that and not on vista!

Now, 2.1 to 3.3 are Wii User Menu revisions, and don't change anything regarding the real functionality of the Wii.

Take for example the trucha bug. The 3.3 Wii menu uses latest IOS and you can't run trucha signed discs, but using a homebrew application that uses an older IOS you can start trucha discs from it.

Wanting to downgrade a Wii is, let's say it nice:

regarding brickblocking and partial bricks: they happen by installing a Wii User Menu revision for other regions, so it's really a problem of the wii menu and not one of the IOS updates, that's why it is possible to unbrick a partial brick and not stay in fear for a failure.

Downgrading means deleting the Wii menu, then taking out IOS revisions then putting in an older wii menu. If something goes wrong after deleting the current wii menu then the Wii is DEAD!

To further explain this, your theory doesn't work because the semi-brick fix doesn't actually remove any old firmware revisions. The semi-brick fix is LITERALLY just another update. It does the same thing a wii does when it's updating like normal. I believe it also does some neat hocus pocus in cleaning up the files that the out of region update would have put on it, but that's the concept here at least. (I'm being purposefully simplistic here, if you really want the technical shit go to hackmii. It's been a while since I've read them myself.)

A wii isn't like a PSP, Xbox, router, or anything else that we're used to with firmware. Usually, when something has firmware it completely overwrites the old firmware with no traces of the original left. With a Wii, each "firmware update" is like a new virtual console game you can download. Downgrading is BAD because it involves physically deleting pieces of the system. Imagine running a program that all it does is "deltree windows *.*" That's what "downgrading" would have to do. In the process of deleting windows, your computer will not boot if you lose power in the 5 minutes it takes for that to happen. Then, once it's all deleted, it slowly copies each file it deleted back on the system... and if something goes wrong during THAT 5 minutes, your system also won't boot. The difference here is that unlike a PC, a wii without it's operating system is a total brick. There is no way to recover from this.

Bushing is working on a true long term fix and he already has more exploits ready to play with if/when the current Zelda hack is fixed for god by Nintendo. There's no reason to worry about downgrading.
