Important Disclaimer: The "MXQ Pro 4K" is a generic media box. There are many different hardware versions of this device that all look identical on the outside but use different chipsets (e.g., Amlogic S905, S905W, S905X, Allwinner). Flashing the wrong firmware can permanently "brick" (destroy) your device. The firmware version Android 7.1.2 usually corresponds to devices running the Amlogic S905X processor. Below is a proper guide on how to identify your device, prepare the SD card, and install the firmware using the Amlogic SD Card Tool (Amlogic Burning Card Maker).

Prerequisites

An SD Card: Minimum 4GB, formatted to FAT32. A Windows PC: The flashing tools are almost exclusively designed for Windows. Identify your Chipset:

Look at the bottom of your box sticker. If you see S905X or S905W , this guide applies to you. If you see S905 (no X) or S805 , STOP . You likely need Android 5.1 or 6.0, and this method may not work.

You will see a code like P201 , Q5 , KIII Pro , or a date code like 20170512 . Search Google for: "MXQ Pro 4K S905X Android 7.1.2 firmware img" plus the board number found inside your device. Note: The file size should be between 500MB to 1.5GB usually. If it is a .zip , extract it to find the .img file inside.

Step 2: Install the Amlogic SD Card Tool
