More information is required. – Ramhound Apr 8 '13 at 12:02
@Ramhound what kind of information should I add? – Tuan Anh Tran Apr 8 '13 at 13:05
Are you trying to remove the DRM or just the password? AFAIK the .prc files are just .mobis with a different extension. should be able to help if it's DRM. – James Apr 20 '13 at 22:28
just the password only but the file is password protected and DRM-protected as well. – Tuan Anh Tran Apr 22 '13 at 0:09
