A: No. Sony prevents downgrading to avoid security risks. Once updated, you cannot revert.
Several firmware revisions were released specifically to address HDMI handshake issues resulting in audio latency. The firmware manages the audio buffer against the video processing pipeline; miscalibrations in early firmware versions necessitated manual audio delay adjustments by the user.
The firmware of the Sony 43W800C is a historical artifact. It represents Sony’s awkward puberty from a hardware-centric display company to a software-dependent ecosystem player. The updates were clumsy, the memory insufficient, and the support life tragically short.
Today, if you unbox a used 43W800C, you face a choice. Update to the final PKG6.407 and accept the slow death of app incompatibility, or disconnect it from the internet, plug in an Apple TV 4K or Roku Ultra via HDMI, and treat the TV as a glorified monitor. In doing so, you bypass the ghost entirely. Because the best firmware for a 2015 Android TV is no firmware at all—just a panel, a backlight, and a $50 streaming stick.
Final Verdict: The hardware is a classic; the firmware is a tragedy.
Note: Always back up your calibration settings before updating firmware. Sony does not allow version rollback on the 43W800C due to efuse write protection on the MediaTek chip.
The Sony Bravia 43W800C remains a beloved Android TV among enthusiasts for its exceptional motion handling and deep contrast levels. However, keeping your firmware updated is essential to maintaining app compatibility, security, and system stability. This guide covers everything you need to know about the firmware for the Sony 43W800C. Why Firmware Updates Matter
Firmware is the foundational software that controls how your TV's hardware interacts with the operating system (Android TV). For the KDL-43W800C model, updates typically provide:
Security Patches: Protecting your home network from vulnerabilities.
App Optimization: Ensuring streaming services like Netflix, YouTube, and Prime Video run without crashing.
Performance Fixes: Reducing input lag and improving menu navigation speed.
Bug Squashing: Resolving intermittent Wi-Fi disconnection or sound syncing issues. Latest Firmware Version Details
As of the most recent lifecycle updates, the Sony 43W800C operates on the Android M (Marshmallow) or Android L (Lollipop) architecture depending on your region. Release Date: Periodically updated through late 2020/2021.
Key Improvement: Improved interface responsiveness and updated TLS protocols for secure internet browsing. How to Update Your Sony 43W800C
There are two primary ways to ensure your TV is running the latest software. Method 1: Automatic Network Update (Recommended) Press the Home button on your remote. Navigate to Settings.
Select About (under the "TV" or "System Preferences" category). Select System Software Update. Click Check for a system software update. Method 2: Manual USB Update
If your TV cannot connect to the internet or the automatic update fails, you can perform a manual flash.
Visit the official Sony Support website for your specific region (US, Asia Pacific, or Europe).
Search for KDL-43W800C and download the latest firmware .zip file.
Extract the file and copy the .pkg file to the root directory of a FAT32-formatted USB drive. Insert the USB drive into the TV's USB port.
The TV should automatically detect the update. Follow the on-screen prompts. Common Troubleshooting Tips
The "Looping" Update: If your TV gets stuck in a boot loop after an update, perform a "Forced Factory Reset" by holding the Power and Volume Down buttons on the back of the TV while plugging in the power cord.
USB Not Recognized: Ensure the drive is formatted to FAT32, as NTFS or exFAT may not be recognized by the 43W800C during the boot phase.
Slow Performance Post-Update: After a major firmware jump, it is often helpful to perform a factory reset from the settings menu to clear out cached system data from the previous version. Maximizing the Life of Your 43W800C
While the 43W800C is an older model, the hardware is still quite capable. If the built-in Android TV interface feels sluggish even with the latest firmware, many users recommend using an external streaming device like a Chromecast with Google TV or an Apple TV 4K. This allows the Sony hardware to focus solely on picture processing while the external device handles the heavy app lifting.
📍 Pro Tip: Always verify your specific model suffix (e.g., KDL-43W800C vs. KDL-43W805C) on the Sony Support site to ensure you download the correct regional firmware.
