I didn't want to have to download or pay for any 3rd party apps that stay open all the time, or only work half the time, and got tired of manually putting the init.d files and changing permissions every time I flash something, so I made some flashable zips (with a little help from XDA members efrant, Moscow Desire, Jonny, and GermainZ).
Figured I'd share, not sure if there's interest; but just in case you're like me and like these mods... Just make sure you have a kernel that supports these mods. I've been using bricked kernel for a while now with zero issues.
Flash the one you want, I included the uninstaller for all. If you flashed both DT2W and S2W and just want one of them, flash the one you want, it will remove the other one.
This eliminates the need to install any app or anything to enable these mods.
Use a kernel you find that specifically states it supports S2W and DT2W.
