How do I install the homebrew channel on the wiiU menu. No I'm not talking about the viiwii. And without using a game
From the OP (read it and then ask any questions you may have):
1. Download and extract the channel version to sd:/install/ (pur your .app files here, not the .zip)
2. run a custom firmware (fw.img for sysNAND or redNAND) with signature patch enabled. The custom firmware needs to be from Nov 18, 2016 or newer.
3. Use WUP installer or WUP Server with install() command to install the Homebrew channel package on a signature patched firmware.
4. To launch the installed Homebrew Launcher, run your fw.bin again and select the homebrew launcher from your WiiU home menu.
NOTE: To install the channel version you need a SPECIFIC fw.img, do not use an existing and previously compiled fw.img, you need to get the newest Dimok's branch and compile with "make cfw" to get the proper fw.img for sysNAND or "make redNAND" to get a proper fw.img for redNAND with The homebrew Launcher compatibility.
If you don't use the correct fw.img, you will get an installation error!
