A database error appears after replacing appinfo.db

What it means

The Y2JB README has an optional step that blocks YouTube updates by editing appinfo.db, the console's app database, at /system_data/priv/mms/appinfo.db. You copy the file with FTP, change it with a script and put it back. The README warns that database corruption can delete all installed packages (FPKGs) and saved data on the internal storage.

What to do

1Back up your saved data before any change

The README tells you to back up your saved data with the PS5's own backup feature in Settings. Also keep the original appinfo.db you copied from the console, unchanged.

2Close YouTube and wait for installs to finish before replacing the file

Close the YouTube app completely, go to the Settings page, and make sure no package is installing or updating.

When to stop

! This can wipe your packages and saves

If the corruption notice already appeared, stop editing and plan a recovery based on your backup. The README warns that database corruption can delete all installed packages and saved data on the internal storage. Do not replace the database again and again, and do not delete files without a recovery plan.
