https://rentry.org/SwitchHackingIsEasyI have no clue what the rentry guide is you keep mentioning so I can't judge on it.
Ah then they changed stuff because it used to be like this:
How to install Signature Patches Download the latest release. If you use fusee.bin to boot into atmosphere, download fusee.zip. If you use package3 to boot into atmosphere, download hekate.zip. If you're unsure on which release to get then check your hekate_ipl.ini file located in your /bootloader/ folder. If you have no such file, then get the fusee.zip release. If you see the following line payload=bootloader/payloads/fusee.bin in your hekate_ipl.ini file, download fusee.zip. If you see the following line fss0=atmosphere/package3 in your hekate_ipl.ini file, download hekate.zip.
Anyway try to directly inject fusee.bin payload and see what that gives you.
I hope linking to this is ok with the forum rules.
Those instructions you posted, as far as I know, are outdated. Correct me if I'm wrong.
Also, what does "directly inject fusee" mean? You mean, without going through hekate?
Hekate is a payload manager, I should be able to use it, I think.
