Bricked wii 4.3u without Preloader
So i recently attempted to install a .wad i made by using Crap through wifi. It said installation successful and i restarted my Wii. it went to the "WARNING-HEALTH AND SAFETY" screen and and i pressed A to continue to the system menu. i could hear all of the sound effects made when the system menu loads like normally, except back screen. i looked it up and was told that i had a banner brick and i had to reinstall the system menu wad. i was told to use an unbrickmii ntsc .rar pack and to install the boot.dol from priiloader, load the installed file, then restart my wii and go back to the priiloader in order to go to the homebrew channel. i tried going to the homebrew option on priiloader but it said "HBC wad missing" or something like that, so i had to go to launch title and select homebrew channel that way. from there i opened the wad manager and installed the system menu .wad. i restarted my wii and now i have the same problem except there are no sounds after pressing A at the warning-health and safety screen plus i am no longer able to go to priiloader, it instead just goes straight to the warning-health and safety screen. what do i do?
btw my wii is on 4.3u and i softmodded it with letterbomb
