While making my Wii U region free my modifying the sys_prod.xml game_region field I accidentally put the wrong game_region (2 instead of the original 4). This is pretty stupid of me but anyway I'm now stuck because the Wii U won't let me access the Settings app (nor the web browser) and says that those apps come from the wrong region. Is there any way to force a factory reset without accessing the Settings app? Or anything I could try? Thanks!
