Hacking 3.4U Low Brick

[alimami]

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.

It probably has a bad bluetooth module. Do his wiimotes power on the wii? If the wii has bricked all by itself, then it is likely the bluetooth module. If your friend did something to it to cause the brick, find out what and post that here. A new module cost about 10 dollors.
