Unfortunately I don’t know of another way to execute a shutdown via software.
Ther have been modifications done via the source code. That’s the only way I’m aware of at this time:
https://github.com/masagrator/Status-Monitor-Overlay
It’s fine. It will work. Hekate does this automatically. Put the version of Hekate you want to run on your SDCard and attempt to boot.
If it doesn’t work…
plug the RCMLoader into your PC
Rename a copy of hekat.5.9.0.bin to payload.bin
place your new payload.bin in each folder on the RCM loader.
try to boot again.
