| Aspect | Verified? | Explanation | |--------|-----------|-------------| | Official from Sony | ✅ Yes | Firmware from Sony Support is genuine | | Untampered download | 🔸 User-dependent | You must compare SHA-256 if Sony provided (they don’t) | | Signed by Sony | ✅ Yes | All official updates cryptographically signed | | Bootloader check passed | ✅ Yes | Verified on device during install | | No known backdoors | ⚠️ Unverifiable | No public audit; old Android version has known CVEs |

Installation Procedure

Step 1: Prepare the USB Drive

• Format the USB drive as FAT32 (default allocation size).
• Extract the downloaded ZIP file on your computer.
• Inside, find a folder named sony_dtv... with a file named sony_dtv0FA30A014A00_00000100_0064100.pkg (or similar). Do not rename this file.
• Copy the .pkg file directly to the root of the USB drive (not inside any folder).

Step 2: Power Off the TV

• Turn off the TV using the remote or physical power button.
• Unplug the TV from the wall outlet. Wait 60 seconds.

Step 3: Insert USB and Boot

• Plug the USB drive into the TV’s USB port (usually the side port works best).
• Hold down the Power button on the TV (not the remote) and keep holding it.
• While holding the button, plug the TV back into the wall outlet.
• Continue holding until you see a green LED light flashing or the "Updating software..." screen appears. Release the button.

Step 4: Wait Patiently

• The update takes 10–15 minutes.
• The TV will reboot once or twice.
• Do not unplug the USB drive or turn off the TV until you see the "Update complete" message and the TV returns to the home screen.

Step 5: Post-Update Verification

• Go to Settings → About → Software Version. Confirm it matches the update version.
• Perform a Factory Data Reset (Settings → Device Preferences → Reset) to clear old cache data. This ensures smooth performance.

The "Verified" Future: Should You Update?

If your Sony 43W800C is working fine (no lag, YouTube works, Wi-Fi stable), you may not need the latest verified firmware. However, update if:

• Apps crash constantly (Netflix, Prime Video).
• TV reboots randomly.
• You face HDMI-CEC issues (e.g., TV won’t turn on with Chromecast).
• Security concerns (old firmware has unpatched Android vulnerabilities).

If your TV is severely lagging even after the verified update, consider an external streaming stick (Fire TV, Roku) rather than risky firmware hacks.
