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. firmware sony 43w800c

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.

Title: A Bittersweet Upgrade: Review of Sony KDL-43W800C Firmware

Rating: ★★★☆☆ (3/5)

The Bottom Line: The latest firmware updates for the Sony 43W800C successfully modernize the user interface and patch critical security vulnerabilities, but they cannot fully overcome the hardware limitations of this 2015 mid-range model. If you are looking for a smoother interface, the update helps—but don't expect a brand-new TV.

Part 6: Reviving the Legacy – Custom Firmware Solutions

Because Sony abandoned the 43W800C, the community has stepped in. Projects like Lineage TV (Unofficial) and LolliW800 attempt to replace the Sony launcher with AOSP (Android Open Source Project) 9.0.

The technical hurdle: The display driver (mtk-tv-disp) is proprietary. Without Sony's binary blobs, custom firmware cannot control the backlight or local dimming. Most custom ROMs run at 60% brightness, locked, or cause PWM flickering at 240hz.

The only successful long-term mod is to flash the "Samba Off" firmware (a modified official PKG that removes the Samba Interactive TV process which consumes 120MB of RAM constantly). Users report boot times dropping from 75 seconds to 42 seconds.

3.1 Major Updates

Throughout its support lifecycle, the 43W800C received incremental updates.

Q: Will updating firmware delete my installed apps?

A: No, an OTA or USB firmware update preserves your apps and data. However, a factory reset after an update will erase everything.

How to Check Your Current Firmware Version

Before updating, identify which firmware your TV is running:

  1. Press HOME on your Sony remote.
  2. Scroll down and select Settings (the gear icon).
  3. Go to About (sometimes under “Device Preferences”).
  4. Select Status or System Update.
  5. Look for Build number or Software Version.

If it shows a version like PKG6.7210.xxxx or lower, you are several updates behind.

Conclusion: A Mirror of Sony’s Transition

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.

This model is part of Sony’s 2015 Android TV lineup (MediaTek platform), and its firmware is unique due to the transition from Android 5.0 Lollipop to Android 7.0 Nougat, as well as its vulnerability to storage issues and the infamous "Sony boot loop."

Part 1: The "Mediatek Mutation" – Hardware Under the Hood

To understand the firmware, you must first understand the silicon. The 43W800C uses a MediaTek MT5890 (sometimes referenced as a dual-core ARM Cortex-A17). This was Sony’s first major foray into offloading smart features from their proprietary X-Reality Pro chip to a third-party SoC.
