    We cannot update with phone, Samsung Kies and other downloaded firmware version after updated to the factory one to XXBLFB. Now the above XXALF2 was changed as the factory one. So What can I do to update for the above condition.Thank you.

  2. The only thing you could do is to install back the official firmware build according to your country of origin. Your CSC code indicates that you have an Asia firmware based firmware.
    Your device currently runs with a modified kernel, its a custom ROM if I'm not mistaken. So therefore you can't upgrade or update via Kies anymore.
