But Hekate already has sleep/wake support (which is what
@Lacius means by warmboot I assume?)
A coldboot exploit is one that can be run just by turning on the console. In other words, the console automatically boots into CFW when you turn it on.
A warmboot exploit is one that can be run by doing something on your console after turning it on. For example, if I turn on my console, open the web browser, and run a homebrew application that loads CFW, that's a warmboot exploit.
A tethered exploit requires that you connect your Switch to another device to load CFW.
An untethered exploit doesn't require that you connect your Switch to another device to load CFW.
Also AutoRCM kinda allows untethered coldboot even if it is slightly unsafe.
AutoRCM is not untethered, since you still need to plug the Switch into something (e.g. computer, Android, etc.) using the USB-C port to load a payload.
Edit: AutoRCM is also relatively safe. If you don't take precautions, you might accidentally drain your battery and need to recharge it using the proper means.
And that post talks about 1.0-4.1, but what about 5.0+?
It is very possible that 5.0.0 and higher will always require RCM to load CFW and homebrew.
Noob question here.
Would any CWF or solution allow us to install something like DLC someday (if not possible already) ?
I would like to install japanese voices for Xenoblades 2 but i don't want to update to access the e-shop
Edit: If you mean pirate the DLC without paying for it, it might be possible, but it's probably going to be a very long time before you can do this.
If you mean legitimately buy the DLC, you will be able to do that when Atmosphere is released with support for emuNAND.
