I'm moving your thread to the brick section where it belongs.
recently i've installed a wrong theme to my 4.1e wii console now everytime i open my wii it tells me "system files are corrupted" i tried pressing the reset button to use preloader (which is installed by the way) but it doesnt work and i dont have bootmii and i dont know what else to do
I want to hear suggestions before telling me to go to the company.
Get a gc controller and do savemiifrii. Update from retail disc to 4.2e.

You can update your wii using the reover menu.
Then you should update it with a game who have the firmware who is newer then your old. Ekemple if you have the firmware version 4.1 on your wii then you need a game with the firmwareversion 4.2 inside.
You can enter the recover menu on your wii using a GC controller by press all the D buttons at the same time.
