Hacking Need Help with my nand.bin and key.bin

[extinct22]

I currently have 5.3.2 u and I did have wiiflow and everything running great up until I tried to install a patch and I ended up losing everything including the home brew channel and now when I try to reinstall smash stack I get stuck at the hackmii screen and the number 1 never comes up so I can reinstall the HBC channel. So my question is I do have my nand.bin and key.bin file how would I reinstall if I do not have the HBC channel to use and if I was able to reinstall my nand.bin and key.bin another way would I be able to put my wii u back to a state where I could reinstall the HBC and get everything back. Any help would be greatly appreciated
