If you installed a theme that wasn't compatible with vWii, you probably bricked your system menu.
If you can't get to the system menu, how did you post a log? Use the updated syscheck.
That syscheck is bogus. Are you sure you just didn't grab a syscheck already residing on the SD you used from your Wii? That log is normal for a Wii from 2009. Hell it has 1.1.0 of HBC when we're at 1.1.2 being the only working version on a WiiU. In fact, it isn't a WiiU syscheck for the simple fact it has a MIOS and BC IOS listed. Are you sure you actually ran Syscheck on your WiiU?
You say your vWii works fine, but now you say you can't load it since it goes to SD card menu and crashes?
You're not telling us something.
