Homebrew Question Is there such a homebrew to shutdown the switch?

[jmleolgq]

Is there such a homebrew(*.nro) to shutdown the switch?
Or is it difficult to write it by myself?

PS: I know I can use DEVMENU to reboot the console.

 

[mooglazer]

Hold down the power button and count to 15

Why tho?

Take out the sd card and the console will power off.

Good idea if you want it to be corrupted

OP never specified that...

i think you have autorcm installed and you want a way to power it off safely. as far as i know there is no such a script out yet. to be safe that it is powered off reboot into hektate or sx os payload and choose power off device. thats the only way i know with a software. the other way is to push the poweroff button for about 15-20 sec like mooglazer already said

A app like this would be awesome not holding down the power button for 15 seconds everytime sounds perfect for autorcm users

On the surface and for a lot of people, this idea might be dumb, but I think this is actually something we need.

I've been looking into this. @rajkosto hekate has power_off() and your biskeydump & memloader have a similar shutdown_using_pmic() function that run in fusee payloads, any reason these couldn't also be called from within a homebrew NRO? I tested it and it compiles but I'm not thrilled to test it on my only Switch.

 

[rajkosto]

PMC registers are secure-world-only post 1.0.0 and the I2C stuff needed for PMIC shutdown is probably not in the whitelisted memory ranges allowed to be poked from usermode

 

[shchmue]

is there a way to dismount the SD card resulting in a system shutdown without corrupting SD or is the shutdown only triggered by physical removal?

 

[rajkosto]

What makes you think that shutdown is any different from the one you get by choosing shut down ?

 

[shchmue]

well is there any other more relevant way to trigger shutdown from within a homebrew app without interaction?

 

[ByteBite]

I just turn my TV off.

 

[shchmue]

that would put it to sleep at best

If you've booted with the service permissions patch, can homebrew then lever enough power to shut down? How about to boot into RCM, I guess that's a whole different ball game?

There are ways but the exploits needed are not public.

I'm not talking about from scratch, running an exploit from OFW. I'm talking about from CFW, when you've already booted from RCM to get full control over the system, so it's a matter of passing along enough of that control to homebrew.

Does choosing Power Off from the power options not actually shut the console down for AutoRCM users? Surely it does.
