My S2 runs on Jelly Bean 4.1.2 (Vodafone UK variant) which is rooted and runs on the Jeboo kernel. I am interested in adding a shutdown sound to accompany the shutdown animation. The sound I am interested in is the boot sound the S2 had when it was on Gingerbread. Would I have to install some app which can add a sound? Or do I have to flash a new boot/shutdown animation altogether? Or is there another solution such as modding the system files?
