I assume you have boot2 bootmi.
Try ohneschwanzenegger again. First make a new nand backup, from your messed up wii. Then format the new nand.bin with ohneschwanzenegger. Be sure to set your setting.txt to match your wii's region and serial number. Then install SM 4.1 with ohneschwanzenegger, let it do its thing. Once you have made the new nand.bin with ohneschwanzenegger, check it with nandbincheck.
Do this from shell-
nandbincheck nand.bin -all -v
make sure there are no errors.
Then restore the new nand.bin
If ohneschwanzenegger does not fix your issue, you possibly have hardware issues. Possibly your wii or your home network. There is nothing software related you can do after that, AFAIK.
