Why won't my Nexus 7 (2012) reboot in safe mode?

According to Asus my operating system is bad and they want me to pay $115 to send it in and put in a new operating system. Is there a way that I could get a new operating system and install it myself. I am computer savvy but will need directions on how to do this.
