Yes. But its an "intelligent lock".
It is locked for reading so it can't be read out. When using EFILive (and only EFILivE), any tune file can be flashed over the top without restriction.
- If the file that you flash over the top is not flagged as "Auto-Lock" then the controller will be unlocked after the flash process.
- If the file that you flash over the top is flagged as "Auto-Lock" then the controller will remain locked after the flash process.
