Just 2 things more...
1. If I restore the original ogg file then it works well
2. If I restore back to the firmware NE2, than I can replace any ogg file and it works well also.
We don't hear reports of problems with anyone using standard sound files. Apparently only to your friends that are trying to manipulate your sound files. And all of you probably doing so in the identical way and incurring the same esoteric error.
It's not impossible to change sound files, but you haven't provided nearly enough information to do more than guess. It's probably a permissions issue or possibly your replacement sound files are formatted or use a codec that is incompatible with the newer firmware. Or any number of less likely reasons.
Unless you provide a lot more information about file versions, file permissions, verbatim error messages, links to before and after ogg files, a step by step and detailed description of how you tried to make the changes and so forth.. it's almost impossible to know what is going on.
