Here is the breakdown of the firmware typically associated with that search string, how to verify it, and how to find the exact match for your device.
Avoid random Google Drive links. Use these trusted sources:
| Source | Reliability | Notes | |--------|-------------|-------| | Chinagadgetsreviews.com | High | Provides OEM stock firmware with checksums | | Freaktab.com (MX9 subforum) | High | Community-verified builds, often pre-rooted | | Amlogic Firmware Repository (GitHub) | Medium | Requires knowledge of .dtb matching | | Official vendor (if known) | High | Rare – most sellers don’t offer support |
The "Android 712" in your search string almost certainly refers to Android Nougat 7.1.2.
Most MX9 4K boxes that run Android 7.1.2 utilize the Amlogic S905W chipset (sometimes S905X). The typical firmware specifications for this model are:
| Symptom | Fix |
|---------|------|
| Device not detected in USB Burning Tool | Reinstall drivers, try USB 2.0 port, short pins again |
| Flashing stuck at 7% / 9% | Wrong firmware – find correct Wi-Fi chip version |
| Red light but no display | Corrupted bootloader – erase flash + reflash |
| Wi-Fi doesn’t turn on | You flashed a variant with wrong Wi-Fi driver – must match RTL/SSV number |
| Remote works partially | Replace remote.conf or sunxi-ir.kl from original backup |
Before downloading any firmware, open your MX9 and check the PCB (Printed Circuit Board). Look for the following:
Wi-Fi Chip:
RTL8723BS – Most commonRTL8189FTV – Older revisionSV6051P – Less common, requires specific firmwareRAM/NAND combo:
K4B4G1646E (DDR3) vs. K4B8G1646B (DDR4) – Not critical for firmware but affects bootloader.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:
cat /proc/device-tree/amlogic-dt-id
Expected output for verified MX9: gxl_p212_1g or gxl_p212_2g.
