M-Horse CT5 Firmware Flash File Download [Stock Rom]

The M-Horse CT5 was an ultra-budget 3G smartphone from 2017, built to be as affordable as possible. It runs Android 5.1 Lollipop on a low-power Spreadtrum SC7731 processor and is equipped with a critically low 1GB of RAM. This hardware combination leads to a severely compromised user experience, defined by constant system freezing, debilitating lag, and frequent application crashes as the system runs out of memory. These performance issues often escalate into more severe problems, such as the phone getting stuck in a bootloop (endless restarting) or rebooting randomly. For owners of this device, reinstalling the official stock firmware is the only practical way to address these deep-seated software issues and restore a baseline of functionality.

This guide provides the official stock ROM package for the M-Horse CT5. 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 V01_20170523 firmware is the definitive method to resolve it if the cause is software corruption. It replaces the entire damaged operating system.
• End Crippling System Freezes: To combat the constant hangs and unresponsiveness caused by the 1GB of RAM, a clean installation of the Android 5.1 OS from this build 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 V01_20170523 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.
