I was following the online guide here: http://www.gbatemp.net/index.php?showtopic=144835 I was up to step 12 (used 4.0U waninkoko updater on step 11) and used an old program (IOS61 and Shop Installer) because I couldn't obtain DOP-IOS at the time to install truncha IOS60. I tried to install the official preloader 0.29 (HAXX) and it said it installed. It said wait, loading in 5s and it never loaded. So I turned off the system and the system menu loads to black. I also started the system trying to get to preloader and it didn't show up. I used Bootmii Boot2 to get back to hbc and used the CIOS downgrader to go back to 3.2U (everything was fine). I then used Waininkoko's 4.0U updater again and it continued to load the screen to black. So I CIOS downgraded to 3.2U and left the person's wii at that. I want to get this person's wii up to 4.0U with preloader because they used SDHC cards and all the games say to update system at 3.2U. Ideas: 1. I think I should use Waininkoko's 4.0U updater again and then use DOP-IOS to reinstall IOS 60 with the v6174 sig hash check to fix the menu loading to black. Then I would have to try to reinstall preloader again. 2. Also in the guide it doesn't to use IOS36 to restore IOS15, might that be the problem? Is my idea right? Do you guys think anything else is wrong here? Thanks!
