Hi, I am looking to purchase a s/h Wii from a second hand shop but due to all this info on the net about the newer Wii's not being able to be modded fully and so on, it is proving something of a mine field. I have been informed that Wii's with LU64 are best avoided if you are thinking of modding. I have come into experience with LEH Wii's which modded okay and allowed me to install bootMii as boot2 no problem. Does anyone know of any other serial number prefixes that are also best avoided? Basically I need to get one that allows boot2 mod and allows backups to run from disc as well as USB. Will I be okay if I get a Wii with LEH on it? I am talking about just PAL Wii's here. Thanks in advance!
