I followed the steps given here and it worked for me : 
http://www.digitalinternals.com/security/decrypt-whatsapp-crypt7-database-messag
es/307/

I have a non-rooted Nexus 5 and was successful to decrypt the database on 
Ubuntu 13.04

Now I'm looking for encrypting the database to crypt7 so that I can restore it 
back on whatsapp with modified chat. I someone happen to know how to do it, hit 
me an email.
