Hi. Been of the scene for quite some time. My WiiU is running 5.4.0 and is spoofed to 5.5.1 with the method in this thread, i've read that required fw is 5.5.1 for IOSU, is there any way to remove/restore the 5.5.1 spoof back to 5.4.0 so I can update to 5.5.1? Or is there any other way to get to...
