I followed the guide in the "Modify ANY Wii 4.3 & below" sticky on here to mod my wii but I'm having some problems. I bought the wii used so I don't know what its original firmware was but when I got it had 3.3u on it. After installing HBC and Bootmii I made a nand backup like it says in the tutorial and then continued on. After finishing the modding process the system menu would only load up about 10% of the time and the rest of time I would just get a black screen and my wiimote would shut off after a few seconds. Priiloader worked fine, as did bootmii, but trying to reach the system menu from them had the same results. I put the backup of the nand I made back on and everything worked fine so I tried again with the same thing happening. I rebooted the nand again and tried a different guide this time (http://www.wiihacks.com/recommended-faqs-guides-tutorials-only/60921-guide-softmod-any-wii.html) in hopes that it would fix it but still the same. The few times the system menu does load up everything works fine, but it doesn't happen frequently enough to make the wii usable by any means. Do you guys have any ideas what the problem might be and maybe know of a way to fix it?
