I want to change platform region permanently from NTSC to PAL using SystemConfigTool on cbhc. Is doing that can cause any brick?
That's a different thing (with its side effects, and can be done easily in systemconfigtool by enabling regions on the option with a line of 3-letter regions or ---) - it's what's called GAME in the Wii's AnyRegionChangeryou can make wii u region free by modifying sys_prod.xml using this guide
