The research was conducted using a mobile-based Facebook messenger application with a conversation scenario created by the author. The study was conducted to restore deleted conversations, the steps used in this study were collection, examination, analysis and reporting. This study also uses two smartphones in the condition that one smartphone is rooted and the second smartphone is not rooted, both smartphones are used as evidence. The acquisition process uses several forensic software including MOBILedit Forensic Express, Systool SQLite and AccessData FTK imager. Digital evidence obtained using the MOBILedit Forensic Express tools is 75%, then Systool SQLite tools are 67% and AccessData FTK imager tools are 67%. The results obtained from this research are conversations that have been deleted and user accounts on smartphones that are rooted while in unrooted smartphones don't get digital proof.
