XFlak said:if the files already exist, they are skipped, and thus not checked
to check all the files that u have (that NUSAD is capable of downloading), enter "A" while in the download log page, note that this wont check for missing files
if after u run the check all feature, and any files show up as red w/ MD5 mismatch, delete those files, and redownload them
edit: it would help if u said what errors u noticed
DeadlyFoez said:Korean wii by default will brick with a 003 error from region changing a wii from korean to any other region and then updated to 4.2. XFlaks app takes care of the issue, but the only issue is that you can't solely use XFlaks app because it does not produce a setting.txt and you need that to be generated for wii to region change.
You are best off with FIRST with doing a nand backup. Then you can run Any Region Changer and going to 4.1u. Next use XFlaks app to download the patched IOS 70 by going to "Batch" (type "B" at the main menu") and then type "70K". You will need to install that file on your wii first before going up to 4.2u
I can't stress enough to make sure you do a nand backup first before region changing a wii...especially a korean wii.
P.S. someone else might have a better way of doing it.
