How to read your friend's whatsapp conversation

How to read your friend's whatsapp conversation.

For this, you need to access your friend's phone for approx 30 seconds.
Follow these steps:
1. Go to MicroSD card of your friend's phone. ( /sdcard/WhatsApp/Databases/)
2. Click on Whatsapp and select Database option.
3. Now you will find 2 files here.
-msgstore-yyyy..dd..db.crypt
-msgstore.db.crypt 
Now take these files from your friends phone and then you can read their conversations that they have done..

Now, its time to restore.
To restore from a backup, follow these steps:
Uninstall WhatsApp.
Decide which backup file you want to restore.
Rename that file from "msgstore-YYYY-MM-DD.1.db.crypt" to "msgstore.db.crypt"
If the file is called "msgstore-YYYY-MM-DD.1.db.crypt5", rename it to "msgstore.db.crypt5"
Install WhatsApp
When asked to restore, tap Restore

You will now be able to see your restored messages. If you want to revert the restoration, simply change the backup filename back to what it was, rename "msgstore.db.crypt.current" to "msgstore.db.crypt", and follow same steps again.
