Hacking Testing for bad BT module?

[hpark21]

All of sudden, my Wii black screened and no longer loads system menu nor HBC (also black screen)

My controller won't sync either.

Fortunately, my Wii is old enough that I had BootMii installed in Boot2, so I reloaded all IOS/cios and re-installed system menu v 4.1U and re-installed Priiloader through MMM.

Finally, my HBC is working again, but USB loaders can not detect my USB hard drive and my Wii controller is still not connecting. When I start the game disk through USB loader, I just get a black screen. I saw somewhere that someone had exactly same symptom as mine and was able to fix it using new BT module.

That said, is there a method of checking whether it is bad BT module or some IOS/Cios issue?

Also, Syscheck gets stuck at IOS202 and won't continue, I re-installed IOS202 several times to no avail.

Thanks.
