===    For that go to 'WhatsApp settings => Chat Settings => Chat Backup'    ===
===              here take a local backup. Prepare for Worst.                ===

===     This script can extract your WhatsApp msgstore.db (non crypt12,      ===
===   unencrypted file) and your 'key' file from '/data/data/com.whatsapp'   ===
===  directory in Android 4.0+ device without root access. However you need  ===
===   to have JAVA installed on your system in order to 'view the extract'.  ===
===  If you don't have JAVA installed then you can 'view extract' later by   ===
===   running 'view_extract.py'. The idea is to install a 'Legacy WhatsApp'  ===
===       temporarily on your device in order to get the android backup      ===
===    permission. You should not lose any data and your current WhatsApp    ===
===   version will be installed after this process so don't panic and don't  ===
=== stop this script while it's working. However if something fails you can  ===
===    run 'restore_whatsapp.py' and reinstall current WhatsApp or simply    ===
===                    update that from Google Play Store.                   ===
===                                                                          ===
