Most Android devices and custom ROMs come with a boot animation which runs for a few seconds after you’ve turned the device on . Here we will show you how to disable it by editing the build.prop file.
Open Build.prop file
You’ll need a rooted ROM, then using a file manager such as ES File Explorer, navigate to the root directory (Long press on the ‘Favourites’ icon in ES).Then go into ‘System’ folder.
Click on the ‘build.prop’ file and choose to open it in ‘ES Note Editor’ scroll down to the bottom and then look for: ‘debug.sf.nobootanimation = 0’, if its not there add in ‘debug.sf.nobootanimation = 1’ at the bottom.
Save and Reboot
Save the file by pressing the menu button and ‘save’ and then reboot. There should now be no boot animation. Remember to always make a full nandroid backup before editing the build.prop file.
