Just a reminder, it is easier if you upload all the mp3s you want to the phone first, then reboot. That will create the MrInfo.db file with all of the names in it. Then change the 0's to 3's as described. Another reboot and they show up in the ringtones list.
Yours might be different, but on mine the pics are under /brew/mod/10888 and videos under /brew/mod/10890
The term 'REBOOT' is used a lot....Does turning the phone off and then back on 'reboot ' the phone ??...and if not how do you reboot a Samsung Sch-U640 ?
Thanks to all
