Document ID: MX9-FW-7.1.2-2024 Product Category: Amlogic S905W / S905X Based Media Player Firmware Version: Android 7.1.2 (API 25) Compiled for: MX9 (Manufacturer Variants: V88, X96, T95, A95X Clones) 1. Introduction The MX9 4K TV Box is a budget-oriented set-top box primarily utilizing the Amlogic S905W or S905X System-on-Chip (SoC). While marketed as "4K" capable, its performance is limited to decoding HEVC/H.265 at 60fps but struggles with high-bitrate 4K remuxes. The device shipped with Android 7.1.2 (Nougat), which is now considered legacy but remains the most stable firmware for this hardware due to driver limitations in newer Android versions.
