Although the splash screen only shows up for a few seconds when booting your phone, that doesn’t mean that it is not important for the whole design experience. A nice looking splash image really refreshes the phone.
Now, there are a lot of custom splash screens available, and there are many to choose from. However, there might be just one specific image you really want to have as a splash screen. XDA member deficitism created a guide to make this possible for you. Using various tools, you will quickly create your own splash screens using the graphics you want.

This is a quick tutorial on creating your own custom splash1 image along with a flashable hboot package.
**Remember, in order to flash custom splash1 screens via hboot, you must have s-off via unrevoked forever.
***I take no responsibility for any damage you cause by performing any of these steps. They are for educational purposes only.
The guide includes a ‘android-info.txt’, which is specifically for the Droid Incredible. In order to flash it to another device, you will have to change the information inside that txt file.
Check out the guide and downloads in the thread.
