How to Identify Your MX9 Hardware Revision

Before downloading any firmware, open your MX9 and check the PCB (Printed Circuit Board). Look for the following:

1. Wi-Fi Chip:

   • RTL8723BS – Most common
   • RTL8189FTV – Older revision
   • SV6051P – Less common, requires specific firmware

2. RAM/NAND combo:

   • K4B4G1646E (DDR3) vs. K4B8G1646B (DDR4) – Not critical for firmware but affects bootloader.

3. PCB Version number: e.g., MX9_V3.1 20171205 or MX9_V2.2 20180620. Match this number exactly when searching for firmware.

If you cannot open the box (warranty void sticker), use the Terminal Emulator app to run: Verified Filename Example: MX9_S905W_7

cat /proc/device-tree/amlogic-dt-id

Expected output for verified MX9: gxl_p212_1g or gxl_p212_2g.

Step 5: First Boot & Verification

1. First boot takes 3–5 minutes (Android animation).
2. Skip setup → install CPU-Z → verify:
   • Android version = 7.1.2
   • Kernel = 3.x or 4.x (Rockchip 4.4.x is normal)
   • Wi-Fi works.
3. Test remote, Ethernet, both USB ports, and AV out.

Before downloading anything, you must open the box (warranty void) and look at the Motherboard (PCB) .

• Locate the Wi-Fi chip: It is a small black square near the antenna wire.
• Look for the PCB version: Printed in white ink (e.g., MXQ-V99, MX9 V3.0, RK3229_D4).

Common MX9 variants:

• Variant A: Rockchip RK3229 + SV6256 Wi-Fi.
• Variant B: Rockchip RK3229 + RTL8723BS Wi-Fi.
• Variant C: Amlogic S905W + HS2734A Wi-Fi (Rare for MX9).

• MX9_4K_S905X_7.1.2_20180828_DDR3_WiFi_AP6212.img
• MX9_S905W_7.1.2_DDR4_SV6051P_V311.img

Trusted community sources (verified by thousands of users):

• FreakTab.com – Search for "MX9 7.1.2 Stock Firmware [Verified]"
• 4pda.to (use browser translation) – Look for the MX9 unified thread.
• ChinaGadgetsReviews – Often repacks factory dumps with checksums.

Instructions:

Step 1: Install USB Burning Tool Download the tool from a reputable source (e.g., Amlogic official mirrors). Install it, including the included device drivers. Reboot your PC.

Step 2: Prepare the MX9 Unplug the MX9 from power. Open the case (optional) and locate the reset button (often inside the AV port or a small pinhole near the USB ports). Alternatively, some units have a NAND pin shorting method – but the reset button is safer.

Step 3: Connect and Force Mask ROM Mode

1. Launch USB Burning Tool as Administrator.
2. Click File > Import image and load your verified .img file.
3. Uncheck "Erase Bootloader" and "Erase Flash" (leave default "Normal erase").
4. Hold the reset button (use a toothpick).
5. While holding reset, connect the USB cable to the MX9’s USB OTG port (usually port #1, often blue or labeled).
6. Connect the other end to your PC.
7. Now plug in the power adapter to the MX9 (some revisions require power; others draw via USB).

You should hear a Windows connection sound, and USB Burning Tool will show "HUB3-1: Connected" or "Device found: WorldCup" .

Step 4: Start the Flash Click Start. The process will take 3–5 minutes. You will see:

• 7% – [DDR]
• 42% – [Initialize]
• 95% – [Burn U-Boot]
• 100% – [Success]

Step 5: Stop and Disconnect Click Stop, then close USB Burning Tool. Disconnect the USB cable and power adapter. Wait 10 seconds. Reconnect only the HDMI and power.

The MX9 should boot into a clean Android 7.1.2 (Nougat) setup wizard.
