If you have a region converted Wii and you update to 4.2 (also with wanikoko's update Need to be confirmed) then you will get a 003 Error.
"error:003 unauthorized device has been detected"
On most forums the 003 Error reports are coming from region converted korean Wii.
Lets find out why and how we can upgrade, for now it's not important, but in the future it can/will be. If this is the case then region converted owners are stuck on 4.1 for always... The new Shop channel v17 is safe to update on a region converted korean Wii, I tested it my self.
So how does ninty check you have a region converted Wii.
1. They do a serial number check? If not matches the region then brick.
2. The 4.2 upgrade checks for leftover IOS 4x (those IOS's are only for korean Wii) if you have then brick.
3, Check key store for Korean key?Most likely it will be this way. -> http://gbatemp.net/index.php?showtopic=183063
And what part of the upgrade does the check.
1. New boot2v4 dont think so, and this boot2v4 is already longer out
2. IOS70. The routine for the key check would be in here
3. System menu. Most likely the system menu calls the routine in IOS70 for the korean key check.
There are 3 ways to prevent this as I can think of.
1. Delete korean key from EEPROM. (cant be done I think, but would be the best way for now and future upgrades.)
2. Change the routine in IOS70 that is never reports the korean key.
3. Kill the check in SysMenu 4.2
Option one would be best, 2 and 3 are temp fixes and every upgrade they need to be patched again.
