Zen Cinemax Force Firmware Flash File Download [Stock Rom]

The Zen Cinemax Force was launched in October 2016 as a budget 5.5-inch smartphone featuring Android 6.0 Marshmallow and an SOS emergency feature. According to verified Flipkart customer ratings, the device received a disappointing 3.3 out of 5 rating based on 40 user reviews, classifying it as “Bad” in overall customer satisfaction. The Cinemax Force shares its Spreadtrum SC7731C chipset and 1GB RAM configuration with its predecessor, the Cinemax 2, which was harshly criticized by Express Computer in their February 2016 professional review for having “unacceptable level of lag, stutter and delay even in using the basic features such as Call or Google Play Store” — performance issues so severe that they replaced the review unit thinking it was defective, only to find the replacement exhibited identical problems. This official V6 stock firmware (build date September 20, 2016) allows users to perform a complete factory reinstallation, eliminating software corruption and restoring the device to its original Spreadtrum SC7731C optimization baseline.

Why Flash This Specific Firmware?

• Fix Severe System Lag and Stutter Issues: Professional reviews of the identically-specced Cinemax 2 (same SC7731C chipset, same 1GB RAM) documented “unacceptable level of lag, stutter and delay” so severe that even basic features like the Phone app and Google Play Store exhibited unbearable delays — flashing the stock firmware removes corrupted system cache, clears accumulated junk files, and restores factory performance optimization for the limited 1GB RAM configuration.
• Resolve App Crashes and System Freezes: Express Computer’s review noted that during multitasking “apps crashed or many a times reported unbearable lag” and “on some occasion, we had to took the battery out to re-start it” — these hard freeze conditions are classic symptoms of system partition corruption that require complete firmware reinstallation to resolve on Spreadtrum SC7731C devices.
• Fix Bootloop and Logo Hang Problems: Spreadtrum SC7731C chipset devices are particularly vulnerable to boot logo freeze and continuous restart loops after failed OTA updates or system file corruption — reflashing this official .pac firmware using SPD Upgrade Tool is the standard recovery procedure for SC7731-based Zen Mobile devices.
• Restore Battery Performance and Charging: The Cinemax Force shipped with a 2900mAh removable battery that Zen claimed would provide “30 hours of nonstop talk time” — flashing stock firmware resets battery calibration data and power management profiles to factory defaults, fixing software-level drain and charging issues that develop on aging Android 6.0 devices.
• Repair Network and Dual-SIM Functionality: Reinstalls modem files and network configuration for dual-SIM 3G connectivity, addressing signal loss, IMEI corruption, or carrier registration issues that can occur after improper flashing attempts or modem partition corruption on Spreadtrum devices.

Bug Fixes and Improvements

• V6 Build (September 20, 2016): Pre-launch firmware compiled two weeks before the October 5, 2016 market release, representing final optimization efforts to address the severe lag and performance complaints that had plagued earlier Cinemax models with the same Spreadtrum SC7731C processor and 1GB RAM combination.
• Eliminates system-wide lag, stutter, and app freezing by restoring clean kernel files and optimized system partitions specifically tuned for the low-spec 1GB RAM and quad-core 1.3GHz processor configuration running Android Marshmallow 6.0.
• Fixes bootloop conditions, logo hang, and hard freeze issues caused by corrupted system files, failed software updates, or incomplete firmware flashes — common problems on budget Spreadtrum-powered devices that require battery removal to restart.
• Restores proper dual-SIM 3G functionality and network registration by reinstalling factory modem files and carrier configuration profiles, fixing the signal and connectivity issues documented in SC7731C modem compatibility problems.
• Resets battery statistics and charging logic to factory defaults, addressing the inaccurate battery percentage readings and abnormal drain patterns that can develop on the 2900mAh removable battery over time.
• Removes corrupted app data and clears system cache that accumulates during prolonged use on devices with only 8GB internal storage, restoring available storage space and reducing bloatware-related slowdowns.

How to Flash the Firmware

Flashing the .pac firmware onto your Zen Cinemax Force requires the SPD Upgrade Tool (also called Research Download Tool or Spreadtrum Flash Tool). Follow these steps carefully:

1. Download the firmware file Zen_Cinemax_Force_SC7731C_V6_20160920_SPD.zip (1.04 GB) and extract it to a dedicated folder on your Windows computer.
2. Install the Spreadtrum USB drivers on your PC if not already installed (driver files are typically included in the extracted firmware folder or can be downloaded separately).
3. Launch the SPD Upgrade Tool (ResearchDownload.exe) as Administrator by right-clicking the executable file and selecting “Run as administrator.”
4. In the tool interface, click the gear/settings icon (labeled “Load Packet” or “Cog Settings”) and browse to select the .pac file from the extracted firmware folder.
5. After the firmware package loads successfully (you’ll see partition details and file information displayed in the tool), click the green play button labeled “Start Downloading” to activate flashing mode — the tool is now waiting for device connection.
6. Power off your Zen Cinemax Force completely. Since this device has a removable battery, open the back cover, remove the battery for 10-15 seconds, then reinsert it (do not power on the device yet).
7. Press and hold the Volume Down (–) button firmly, then connect the phone to your computer using a quality USB data cable while continuing to hold the volume button pressed.
8. The SPD Upgrade Tool will automatically detect the device in download mode (you’ll see a COM port notification) and begin flashing the firmware — you can release the volume button once you see the progress bar advancing with partition names.
9. Wait patiently for the flashing process to complete without interruption. This typically takes 8-15 minutes depending on your USB port speed and cable quality. The tool will display a large green “PASSED” message when finished successfully.
10. Click the “Stop” or “Stop Downloading” button in the tool interface, then disconnect the USB cable from the phone. Reinsert the battery if removed, and power on your Zen Cinemax Force. The first boot after flashing may take 5-10 minutes as Android rebuilds the Dalvik/ART cache and optimizes system apps.
