wow , the seller din ask u not to do that??

there are ways out there (which claims to be successful)...but it involves opening up the wii and performing a bypass or something which is sooo complicated

But, i think there's even a vid showing how it is done (as far as i can recall)...however, i doubt anyone would be really be willing to go that far for something that he or she doesn't know how to do...it may even cause some other internal damage to the hardware too...who knows?XD

RIP cham

If you know me , i sure ask u no matter wad u do DONT UPDATE lolx

My friend's wii has recovered back to life by changing the motherboard

i found a lot of wii motherboard for sale.... u think this can solve my problem?? haha... thanks guys for the infos~

The screen says:
Error:003
unauthorized device has been detected?

Can still buy motherboard and fix the problem?

WARNING
Do not update to 4.2 if you have a region changed Korean Wii. If you do, you get the famous 003 error (=brick). If you really need the update, install IOS70 from cIOSCorp 3.5

Error 003
cause: Korean region changed wii, updated to 4.2

It only occurs when a Korean region changed Wii (a wii that was originally Korean) updates to 4.2. Once you get the error, there is no way (yet) to restore from it (since BootMii as boot2 gets overwritten as well!).

So since you can't restore from it, lets see how to prevent it.
Required
* [Method 1] Korean Wii softmodding requirements
* [Method 2] Wii.py and WAD editing/Python knowledge
* [Method 3] Priiloader, Wad manager (or YAWMM)

Method 1

    * Use this guide to softmod your Korean wii without region changing

Method 2

    * Patch the System Menu 4.2 TMD to use as IOS other than IOS70 (IOS60 for example)

Method 3

    * Install IOS 70 and System Menu 4.2 via WAD manager
    * Install Priiloader without restarting the console
    * Use Priiloader to boot the System Menu with IOS60 (for example)

Even bootmii isn't safe from this? Holyshit that's nasty.

Do shops generally bootmii the wiis before selling them? Oughta make it a lot easier to reflash bad updates or somesuch, right?

Since you seem to be in the know, how much cheaper are the korean machines when you get them fresh off the boat, compared to japanese or UK or US or aussie ones? I'm just really curious.
