Did this eventually work for Master_yoda? I'm curious because I'm kind of in the same boat. I bought my wii over 10 years ago in Japan. I soldered the chip. Put it in my closet for years. Busted it out one day and threw in a US game and ran the update and semibricked it (can't access settings). Then it went back into the closet until this week when my son was interested in playing Mario Kart. I never installed HBC on it. I've tried almost everything (bannerbomb and everything in this thread) but nothing seems to work. The SD menu says it's reading my card and then either populates the menu with a question mark, corrupted files error, or just empty little windows. I really want to get the MAC address to try letterbomb or connect to WIFI but I need to get to the settings. Would getting a USB LAN adapter work? I've pulled it apart and couldn't locate the MAC address posted anywhere inside. I have version 4.x because I do have the SD card icon on the menu page. Now it's just a battle of wills to beat this pesky little device. Would getting some new game that has an update on it do the job and open up my settings again?
