Restoring the NAND via bootmii as IOS is only recommended as a last resort and usually does not work. From the date of your drive I am guessing this is a boot2 machine. Your syscheck shows an out of date mod. Since you can still access HBC I would follow the softmod any wii guide and install the patched 4.1 SM that is in it. Hopefully that will get you back up and running.
