Description

The so called Error 003 occurs when a System Menu 4.2 or higher from a different region gets installed onto a Korean Wii.

Technical cause

System Menu 4.2E/U/J and higher call a new ES Ioctlv(0x45) which got added in IOS70. On older(check!) IOSs this Ioctlv always returns -1017.

IOS tries to encrypt a certain byte pattern with the Korean key and then compares it with hard coded values, if the result matches it returns 0 which will then trigger the error in the System Menu.

Fixing

Error 003 Wiis can only boot in region game discs from the recovery menu. Due to the enhanced region blocks of system menu 4.2/4.3, it is not possible to update these error 003 4.2/4.3U/J/E Wiis to 4.3K and there is no known disc with 4.3K update on it. One way to fix a 003 error Wii is to replace IOS70/80 with IOS60-v6174 installed into IOS slot 70/80. Installing IOS60-v6174 into IOS slot 70/80 will remove the Korean key check found in IOS70/80, thus fixing the Wii.

Currently all USA/PAL error 003 Wiis can be fixed by loading Super Smash Bros. Brawl from the recovery menu, running Smash Stack PAL then installing IOS60-v6174 into IOS slot 70/80.

Due to the enhanced region checks of system menu 4.2/4.3, Super Smash Bros. Brawl cannot be directly loaded from the system menu. However these region checks can be bypassed by loading an in region game disc, then swapping the disc to SSBB-PAL and restarting the Wii. There are a variety of methods depending on the game used; some games work, many games do not work.

All error 003 Wiis 4.2/4.3U/E are 100% fixable providing you have a modchip. Disc swapping methods utilizing "Mario Kart-PWNS" and DiscSwap-PWNS" will fix the issue. Unfortunately SSBB-PAL/Kor will not load on a Wii with the Japanese language setting, so SSBB can not be used as SSBB-Jap will not autoboot.

If SSBB cannot be used to fix error 003, the only other solution is to load an IOS used by a game that has the Trucha bug present, then disc swap to an app to fix the Wii using that IOS. If a NAND backup was made with BootMii or the NAND keys where acquired prior to the brick, NAND programming can also be used to fix this error.
