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

The M-Horse Stylus is a budget Android smartphone built on the Spreadtrum SP7731GEA platform, running Android 5.1 Lollipop. As is common with devices in this category, users can encounter critical software issues that render the phone unusable. These problems often include the device failing to power on and only showing a black screen, getting stuck on the M-Horse logo (bootloop), or having the flashlight blink once before failing to boot, which can happen after a failed flashing attempt.

When standard troubleshooting like a factory reset fails, the only solution is to perform a full firmware reinstallation. This guide provides the stock ROM for the M-Horse Stylus. It is crucial to note that because this is a Spreadtrum device, the firmware must be flashed using the SPD Upgrade Tool (often called ResearchDownload Tool).

M-Horse Stylus Firmware Details

Below are the technical specifications for the M-Horse Stylus. This firmware is for the SP7731GEA variant and will restore the device to Android 5.1. Flashing requires the SPD Upgrade Tool, not tools for other chipsets.

Download Official Firmware for M-Horse Stylus

Two firmware builds are available. Note that while these are labeled for the SP7731GEA chipset, they are in .zip format. SPD Upgrade Tool typically requires a single .pac file. You may need to find the .pac file inside these archives after extracting them.

Why Flash This Specific Firmware?

Flashing the official stock ROM provides direct solutions to real-world problems reported by users of Spreadtrum-based M-Horse devices:

• Fix a “Black Screen of Death”: If your phone is completely unresponsive and only shows a black screen after a bad flash or software error, flashing this official .pac firmware is the standard method for unbricking Spreadtrum devices.
• Resolve a Stuck Boot Logo: When the phone powers on but never gets past the M-Horse logo, it indicates system file corruption. A full firmware flash replaces these damaged files and allows the device to boot normally.
• Correct the “Flashlight Blink” Error: A very specific issue reported after a bad flash is the phone’s flashlight blinking for a millisecond upon a boot attempt, followed by nothing. This indicates a critical error in the bootloader or kernel, which can only be fixed by overwriting it with a clean firmware installation.
• Restore Functionality When Recovery Mode Fails: If you can no longer access the Android recovery mode to perform a factory reset, flashing with the SPD Upgrade Tool is a lower-level, more powerful alternative that completely bypasses the broken recovery partition.

Crucial Prerequisites Before Flashing

This process will permanently erase all data. Back up your files if possible.

• The latest version of the SPD Upgrade Tool (or ResearchDownload).
• The correct Spreadtrum USB drivers installed on your Windows PC.

How to Flash the Firmware

This is a Spreadtrum device and must be flashed with the SPD Upgrade Tool. The process involves loading a .pac file.

1. Download and extract the firmware file (e.g., M-Horse_Stylus_SP7731GEA_V07_20160811_5.1.zip) and locate the .pac file inside.
2. Install the Spreadtrum drivers on your computer.
3. Launch the SPD Upgrade Tool, click the ‘Load packet’ gear icon, and select the firmware’s .pac file.
