ive successfully transferred and customized my .caf file before, i have all my ui sounds customized.....for some reason now after trying to repair some issues i had when i transfer my custom .caf files into winscp they only show up as silent on the iphone.

files 1 2 & 3 are working but 4 5 & 6 are not ive tried various files including the original ones, am i missing something do i have to ssh into the phone under a different file protocol.
before i copyed the files then overwrote them this is the correct way? yes they are named exactly as original any help would be greatly appreciated ty
