= This script will extract the WhatsApp Key file and DB on Android 4.0+ =
= You DO NOT need root for this to work but you DO need Java installed. =
= If your WhatsApp version is greater than 2.11.431 (most likely), then =
= a legacy version will be installed temporarily in order to get backup =
= permissions. You will NOT lose ANY data and your current version will =
= be restored at the end of the extraction process so try not to panic. =
= Script by: TripCode (Greets to all who visit: XDA Developers Forums). =
= Thanks to: dragomerlin for ABE and to Abinash Bishoyi for being cool. =
