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."

Alternative Custom Firmware (Not Recommended)

Some tech forums discuss “custom” or “patched” firmware for the 43W800C to enable root access or remove ads. Avoid this. Custom firmware often breaks Netflix Widevine DRM (reducing streaming quality to 480p) and can permanently damage the tuner. Stick to official Sony firmware.
