If you where looking to change your boot image before I have found an amazing app for that lol its called boot changer lite you can get the paid version or the free lite version of course you have to be rooted sorry guys but there shows a feature that you can upload your own image and the free version have images but this always is a use at your own risk like anything else is rooting and voiding your warranty check it out and they dont load slow ether yay
