Translating a chat.db-wal File

Hi there,

I need to recover some deleted iMessages but they're 1) Over 30 days old, 2) Not on any of my backups and 3) Not on any of my other devices. I do, however, have a "chat.db-wal" file that' dates back to the necessary time frame. But, when I open it, it's just a bunch of illegible symbols, numbers and letters. I spent hours troubleshooting with some fantastic Apple Advisors on the phone, but we all remained stumped.

I downloaded "SQLite Flow" from the App Store, but when I go to open the chat.db-wal with that software, nothing generates. Does anyone know how to translate this kind of a document into something legible? Perhaps reverse engineer the data in it?

Thanks in advance for any and all suggestions.

The -wal is the write ahead log. It may have information in it, but not in a structure that may be identifiable.

This may help recover something, but you would still need to know SQL to read the information stored in the recovered database.

Open chat.db, which likely knows about chat.db-wal. Yes, it is a sqlite3 database with likely a bunch of tables in it, but uncertain if you can actually recover valid iMessages in a usable file format from that database. You may have to do one or more SQL joins to get at what you want, even if it is possible.
