Agar aap apni hi WhatsApp files/backup se restore karna chahte hain, toh WhatsApp Settings > Chats > Chat backup se Google Drive ya local backup restore karne ki koshish kar sakte hain. Dhyan rahe: isse aapka current chat data overwrite ho jayega, aur bina doosre ki anumati ke unke account se chats recover karna na ke barabar hai.
