If you lost Bravia Engine or Walkman features:


  • Error: "Device cannot be unlocked"

  • Error: "Error sin_open_device"

  • Windows Defender / Antivirus blocking FlashTool:

  • Click Flash.
  • Wait. The process takes 5–15 minutes. Do not disconnect the cable.
  • You will see "Flashing finished. Please unplug and start your phone."
  • Solution:

    Copy your downloaded .ftf file to: C:\Flashtool\firmwares\ Do not rename the file – keep the original structure.

    Why stick with v0860 when v0.9.18 exists? flashtool v0860 updated
