Priiloader No Sync Workaround Please dont be angry i just wanna share some knowledge!
Ok, background - softmodded a wii (new versoin with NO gamecube ports!), used priiloader to set it to autoboot to CFGloader, then the remote was synced to another wii and remote wont sync back as sync doesnt work in USB loader.
Answer? - Well i dont know how definitive this is or correct but the way i got around it was power on the wii, hold reset to get priiloader menu up, then quickly press reset approx 10 times and then throw an eject in there and then repeatedly press reset again. It then went to the heath and safety screen allowing me to sync remotes back up.
Hopefully this will save someone the hours it took me figuring this out.
