Hi, Your phone is probably in what is known as "bootloop". There is a way to recover from this but '''read and consider the disclaimer''' contained in the following link which describes how to resolve the problem. http://www.droidviews.com/restore-your-motorola-droid-razr-from-bootloop-using-fastboot-files/ If you do not feel comfortable about doing it , DON'T. Take it to a repair centre and see if they will do it.
