I'm on 3.2U on my real nand. Used Bootmii to create a NAND dump, extracted the nand.bin with ShowMiiWads. Then I used crediar's SNEEK Installer to install the regular SNEEK to my SD card. I booted it, played a bit with it and everything was working fine so far.
Next I wanted to try out 4.2U so I used the guide to create a virgin 4.2U. I wiped the SD card clean, used SNEEK Installer again, only this time I selected SNEEK+DI. It showed me a black screen for several minutes, I figured it was just rebuilding so I waited for like 10-15 minutes. Still nothing, so I added font.bin on the SD card's root, tried again and this time it would boot in mere seconds, presenting me with the Wii's initial setup screen. Everything went well, I checked the settings and the SNEEK NAND was indeed on 4.2U. In the guide it mentions to use the System Update (I don't know why really, it's already on 4.2U?) so I did a System Update. This went excruciatingly slow, took like close to an hour.
After the update finished, it asked me some questions like if I wanted to use Parental Control etc. I continued on and then the Wii rebooted and showed me the waving system menu icons (you know, like when you normally boot the Wii, it kinda waves those icons and then it shows the system menu), only this time it kept waving. Those icons just kept on disappearing/reappearing so I just shut off the Wii. Then when I tried to boot again, I was greeted with a simple black screen. No big deal I figured, must've shut it down during some update or whatever, so I wiped the SD card clean again, used SNEEK Installer once more (SNEEK+DI again), then I copied over the virgin 4.2U again. It just showed me a black screen (forgot to copy over the font.bin) so I shut it down after a few seconds and put the font.bin on there. Inserted the SD card into the Wii again, but now it just keeps showing me a black screen.
Is it possible that it takes like 10-15 minutes to rebuild stuff at that time? Because it was 3AM so I didn't have the time to wait for another 20 mins to see what it would do. Just wondering what went wrong. Also, if you UNEEK, what kind of file system does it need? I have a WD MyBook that is splitted in 2 partitions (NTFS and WBFS) so it would be awesome if I could use that without wiping it clean. Ideally, I want to be running PUNEEK. I guess it's a modded build of UNEEK so I can just replace the core files with the ones from the webpost autoreply email?
