the files have to be in .ogg format and be labeled Lock.ogg and Unlock.ogg. i used advanced wma workshop to convert the files from mp3.
to put them on your phone if anyone wants this
1 reboot into recovery
2 mount /system
3 open cmd and nav to your sdk/tools folder
4 pull system/media/audio/ui (this will backup the files before you replace them)
5 copy the backed up ogg files from your sdk/tools folder to another safe location and put the modified ogg files into the sdk/tools folder
6 push Lock.ogg system/media/audio/ui
7 push Unlock.ogg system/media/audio/ui
8 unmount /system and reboot
also if anyone does do this could someone upload the backed up files for me i didn't think about doin the pull till i wrote this up and i don't feel like doing a nandroid restore to get them back.
edit my buddy confirmed that i had these backwards i guess that is what i get for not listening to the files first. i reuploaded with correct file names
