Some more info: before entering the password in terminal, I noticed size tmp/whatsapp.ab 549 bytes, way to small to contain msgstore size 758 kB. Having read https://sourceforge.net/p/adbextractor/discussion/general/thread/2c3ede27/ , I hex edited version #5 to #4 in whatsapp.ab, and then entered the password. I noticed no errormessage, but also no output files.
