I was following xzxero's guide here, the older one from 2 days ago and not the one he just updated, but from this thread: http://gbatemp.net/index.php?showtopic=171901 I completed all of the main steps, bannerbomb to install HBC, Bootmii as IOS but haven't made a NAND backup yet, deleted stub IOSes, Trucha bug restored, and installed the wads for IOS70 and IOS249 rev 14 (I didn't install the 222 and 223 ones yet). I also installed the USB Loader GX Forwarder. I then went to install Preloader as a final step to prevent accidental updates. First time I tried to install it, it dumped. I rebooted the Wii and everything came up just fine including the system menu, so I tried to install Preloader again. This time Preloader installed correctly and I rebooted the Wii again. Preloader came up and I enabled the system menu hacks to press A at health screen and disable disc and Internet updates. I clicked to start the system menu and the screen went blank for a second and then Preloader came back up. For a few times I could click to go to the HBC, but now loading the HBC gives me garbled video and that's it. Preloader still works and I can get into Bootmii. I can also install and load a program using Preloader. Right now I have the Wad Manager working. I tried to reinstall the IOS70 wad listed in the guide a few times (never uninstalling it), but it's still no go. I also tried reinstalling the IOS249 rev 14 without uninstalling. I do not have a NAND backup of this Wii yet. It was running 4.2U when it arrived at my house. It is a LU39 serial. It is a US model Wii. I haven't done anything else to it to try to fix it. It is the third 4.2U Wii that I've tried to hack. The other 2 Wiis went just fine. I don't claim to be an expert, so please try to be very clear with any instructions you give. Thanks in advance.
