The M-Horse F3 is a budget Android smartphone powered by the Spreadtrum SC7731 chipset and running Android 6.0 Marshmallow. Like many devices in its class, it is prone to critical software issues that can leave it unusable. Users of similar Spreadtrum devices have reported problems like the phone showing a black screen after a failed flash attempt, getting stuck in a perpetual bootloop, or being completely unresponsive.
In these situations, the only reliable fix is to perform a low-level firmware reinstallation. This guide provides the official stock ROM for the M-Horse F3.

Why Flash This Specific Firmware?
Flashing the official stock ROM provides targeted solutions for the most severe software problems affecting the M-Horse F3:
- Fix a “Black Screen” After Failed Flash: A common and scary issue is the phone’s screen remaining completely black after an interrupted or incorrect flash attempt, even though the PC might still detect it. This official PAC file is designed to correctly initialize the display and system partitions, restoring your screen and making the phone usable again.
- Resolve “EMMC Problem” Symptoms: If your M-Horse F3 hangs on the logo even after a successful flash or hard reset, it could be what technicians call an “EMMC problem,” where the internal memory is not accepting write commands correctly. While this can indicate a hardware failure, a final attempt with a clean, official firmware like this one is the last and best software-level step to rule out a simple corruption issue.
- Unbrick a Dead Boot Device: This firmware is the primary solution for reviving a completely dead M-Horse F3 that won’t power on, charge, or be detected by a computer in any normal way. Using the SPD Upgrade Tool forces the essential bootloader files onto the Spreadtrum chipset.
