Hi, I've been trying out various Xposed modules on my new Note 4. Each time I try something new, I like to go back to stock firmware. So this means I completely format install the stock firmware with Odin. But each time I do this, I lose all my BBM chat history. Every time I install BBM after each reset, I make sure to have the "Save Chat History" setting turned on. But nothing ever gets saved or restored. Any help would be appreciated.
