M-Horse Mate 9 Firmware Flash File Download [Stock Rom]

The M-Horse Mate 9 was an ultra-budget 3G smartphone from 2017 that borrowed its name from a more famous flagship. It runs Android 5.1 Lollipop on a low-power Spreadtrum SC7731GEA processor and is equipped with a critically low amount of RAM (typically 1GB). This hardware is severely underpowered for the operating system, leading to a deeply compromised user experience. The most common problems include constant system-wide freezing, debilitating lag that makes the phone almost unusable, and frequent application crashes as the system runs out of memory. These issues often escalate into more severe failures, such as the phone getting stuck in a bootloop or rebooting randomly. For owners of this device, reinstalling the stock firmware is the only reliable method to address these deep-seated software issues.

This guide provides the official stock ROM packages for the M-Horse Mate 9. As a Spreadtrum (UNISOC) device, it must be flashed using the SPD Upgrade Tool.

Why Flash This Specific Firmware?

A full firmware reinstallation is the only practical solution for the severe, hardware-induced problems this phone faces:

• Fix a Startup Bootloop: If your phone is stuck restarting at the M-Horse logo, flashing the 08092017 firmware is the definitive method to resolve it if the cause is software corruption. It replaces the entire damaged operating system with a clean copy.
• End Crippling System Freezes: To combat the constant hangs and unresponsiveness caused by the limited RAM, a clean installation of the Android 5.1 OS clears out all software clutter, giving the system its best chance to operate without freezing.
• Resolve Unreliable Wireless Connections: If you are experiencing frequent Wi-Fi or Bluetooth drops, flashing the firmware will reinstall the original radio firmware and drivers included in the 08092017 package, which can solve persistent software-level connectivity bugs.
• Recover an Unresponsive “Bricked” Phone: In a worst-case scenario where a software error has left the phone completely unresponsive, forcing a firmware flash using the SPD Upgrade Tool is the last available recovery method.
