Hey everyone,
I've been trying to make an mp3 ringtone on my phone. It's a Sony Ericsson W380a. I've followed guides to protect the file using the sony Ericsson DRM Packager, and I've made the .dm file and copied it to my phone. However, the file will not play, let alone become a ringtone on my phone.

I checked out the information of the file, and it says the Activation Status of the phone is "locked". The other files on the phone that have worked as ringtones have been "unlocked". What can I do to unlock the .dm file?
