As of now I have a non-existent phone number on WhatsApp. My tablet has been running really slow lately so I decided to factory reset it. I backed everything up with titanium backup and also backed up WhatsApp chats to Google drive. I really don't want to create a new WhatsApp account because I'll have to notify all my contacts etc. but as I don't have the phone number that I originally obtained my WhatsApp number anymore I wanted to know if there is a way to restore my WhatsApp account either from the drive backup or titanium backup? (Sorry for the illegibility I've been working on this problem the whole day)
