hi people. my friend has sent me a bricked wii to fix it. its low brick because the health safety screen doesnt show up and i just have a black screen. i tried savemii and found out that its system menu is 3.4U. i put a drivekey chip with autoboot activated on it but it doesnt boot any disc. i tried Universal Unbricker and many games but none of them worked. now what should i do? are there other ways to unbrick? thanks.
