So, after rooting using a custom ROM and rooting my phone somehow WhatsApp wont let me back up my chat history anymore, see below. The problem now is that I want to transfer my chat history from my old phone to a new one.
From what I've gathered WhatsApp Backup files are crypt12 encrypted msgstore.db files that are located at the root directory /data/data/com.whatsapp
Things I have:
- Old Backup from a few months ago
- my current unencrypted msgstore.db through root access
- crypt12 key file through root access
My plan now is to basically create a new backup by encrypting my current msgstore.db and transfering that to the new phone, hopefully recovering my chats. The only thing I need is a way to reencrypt the file to be the same as a WhatsApp Backup File. Or just modifying my existing, old backup with the new content. Is this possible?
