Init.d Support for Any Rooted Phone
Init.d plays an important role in the world of Android development and customization It allows users to install scripts and mods to be run at boot—everything from battery tweaks to performance tweaks. It essentially opens the door to a world of mods only possible through the Init.d process, which in turn is usually only available on custom kernels.
XDA Senior Member Ryuinferno has developed a script that allows the use of Init.d scripts on any rooted phone, without relying on a custom kernel. Term-init is simply a script that you run in terminal emulator, which will automate the install process, as well as adding a few extra features thrown in by the developer. After this is done, Init.d support will be yours!
Ryuinferno has also created an alternate method of implementation by use of a flashable zip, known as Zip-init, which gets installed in recovery in the usual way.
The only things required to use Term-init or Zip-init are your rooted phone, Busybox, and a terminal emulator app.
