recently, my usb loader gx gets stuck on the loading.... screen. i have to power down the wii from the console and turn it back on. i'd say it does this maybe 1/3 times now. i am on cios 249 rev20. 4.2u
You can try reinstalling your cIOS and reinstalling usbloader. I would go with cIOS249 rev17 or rev19 as rev20 isn't recommended by this forum. If that doesn't work you might have to consider the problem may be with your hard drive. I would try a different hard drive or USB card to see if you still have the same issue.
Brick My Wii is definitely a good term for it. I attempted to use it on two different versioned wiis (twice each) and it completely fails on every level. F--. Please follow the steps mentioned in earlier posts and avoid this God-forsaken piece of crapware.
You need to drop your cIOS 249 to rev 17, nothing later is supported right now. You may also use Hermes 222 v4 (NOT 5) installed on 38 merged with 37.
