I have preloader rev4 installed and my wii started up in preloader menu. when i changed it to 'system menu' to boot , the wii powered down whenever i wanted to turn it on. I changed it back in menu to preloader, hbc...to startup but nothing worked to boot up my wii. And yes i've 'saved settings'. I tried to find a solution on the www but didn't find anything to solve this.
Now i found it myself and want to share it with you guys.
Make the changes you want (eg. boot system menu) , then start a game that gives error#002 blue screen, power off your wii and boot again. Now it will boot with the changes you made.
Ps. sorry if my english is bad (I'm Flemish-speaking from Belgium)
Edit: This helps only ones, Whenever i turn the wii off and on i have the same problem again.
Is there anyone who can help my with this problem?
