Whatsapp backup for new and old chats I recently accidentally deleted a chat in Whatsapp for Android 7.0 &quot;Nougat&quot;. I know if you uninstall and reinstall the app, you can download the backup containing these old messages. Now my problem is, this certain contact messaged me again after deleting the chat, so if I use the uninstall method, I lose all the chats from after the deleted ones. If I say &quot;backup now&quot; as to keep the new messages, it will delete the old backed up messages and only keep the new ones. Is there any way I can have my bread buttered on both sides and get my old messages back while still keeping the new ones?
Thanks in advance.
If these messages are important, you can root your phone in order to restore them.
There are many methods to root Android 7 to use at your own risk.
WhatsApp make a backup of the messages database each day at 2:00 AM, these databases are stored encrypted in /sdcard/WhatsApp/Databases/. The key used to encrypt the backup is stored in /data/data/com.whatsapp/files/key which can be accessed only if you have root privileges.
To restore your previous messages:

root your phone
enable USB debugging
dump the encrypted databases

adb shell pull /sdcard/WhatsApp/Databases/ 


dump the key

adb shell pull /data/data/com.whatsapp/files/key


use this python script to decrypt the encrypted databases:
