Problems restoring downgraded WhatsApp
I've just performed a downgrade of WhatsApp on a Huawei Y6P model using UFED. Downgrade was unsuccesfull and so was restoring the original apk. I get a message on the phone when trying to restore the original apk which transaltes to: "The signature of the packet does not coincide with the installed aplication". Now I can't open WhatsApp on the phone. I can access the msgstore.db file (CRYPT12) but don't know what to do from here or how to succesfuly restore the app.
Any help is appreciated.
