Not very difficult to add the sound back to boot up. Here's what you do.
1:We're going to navigate to the "system" folder. I use Root Explorer.
2:Make sure the folder is mounted r/w, then creat a folder and name it "sounds".
3:In the "sounds" folder, create a folder and name it "poweron"
4:Add your .mp3 file you want to use as the bootup sound and name it "PowerOn".
5:Reboot phone and listen to the sound.
