[Android Apps and Games] :
Hello everyone!

I used Version: v4.7-E1.0 (08/05/2019) (.bat file)

After removing current version of whatsapp it asks me to reboot the devie, but after that, when i unlock the device, nothing happens.

If I run Powershell script, i get thist:

=========================================================================

= 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. =

= ### Version: v4.7 (12/10/2016) ### =

=========================================================================
