The M-Horse CT4 is a budget Android smartphone based on a Spreadtrum chipset, running Android 5.1 Lollipop. As with many devices in this category, it is prone to critical software failures that can render it completely unusable. Users of similar M-Horse and Spreadtrum devices frequently report issues like the phone becoming totally dead after a failed flash, getting stuck on the M-Horse logo, or being infected with persistent malware.
When a phone is bricked or stuck in a bootloop, a full firmware reinstallation from a computer is the most powerful recovery method available. This guide provides the official stock ROM for the M-Horse CT4. As this is a Spreadtrum device, the firmware comes in a .pac file format and must be flashed using the SPD Upgrade Tool (also known as ResearchDownload).

Why Flash This Specific Firmware?
Flashing the official stock ROM provides direct solutions to real-world problems reported by users of M-Horse and other Spreadtrum devices:
- Unbrick a Phone That Is “Dead After Flash”: A very common and stressful issue is when a phone becomes completely unresponsive—no power, no charging light—after a flashing process was interrupted or failed. Flashing this official
.pacfile is the standard procedure technicians use to revive a Spreadtrum device from this “hard-bricked” state. - Fix a “Hang on Logo” Bootloop: If your M-Horse CT4 powers on but never progresses past the static M-Horse logo, it’s a clear sign of a corrupted operating system. This firmware replaces all essential boot and system files, fixing the error and allowing the phone to start normally.
- Remove Malware and Unwanted Apps: Budget devices are sometimes targeted by malware that installs unwanted “sexy” or ad-related apps that cannot be uninstalled through normal means. A full firmware flash is the most definitive way to wipe the device completely and ensure it is free from all malicious software.
