Converts the Whatsapp crypt 8, crypt7 and crypt5 databases to the old version of crypt database! Republish as 1. 3. 1 because play store seems to not have published v1. 3!? Reads the file /sdcard/Whatsapp/Databases/msgstore. Db. Crypt8 or 7 or 5 and converts it to a file /sdcard/Whatsapp/Databases/msgstore. Db. Crypt. Please be patient.
