I was playing around with the Customize app and as a test changed the sound for unlocking (slide bar). I now want to revert back to the original sound but cannot do it. I even deleted the customize theme that the new sound came with and it still plays each time I unlock the phone. Does anybody know how I revert back to the original sound. In the customize app I have already select Revert to Backup but nothing happens. Any help?

hmmm thats no good. I found that when you uninstall customize, any changes you've made to sounds and images stay put even though its been uninstalled. When I reinstalled I was able to revet back to the original sounds... Have you tried setting the sound to something different to what its stuck on??

yes. That works but it won't revert back to the original sound. It always stays on the new sound regardless of whether you delete the theme.

I'd suggest reinstalling custo, then when you choose a system sound, there's an option to "revert to backup". works for me.
