Zen Cinemax 3 Firmware Flash File Download [Stock Rom]

The ZEN Cinemax 3 (SC7731) was a smartphone that, despite its name suggesting a focus on media, was plagued by a critical camera failure according to widespread user reports. A significant number of owners encountered a persistent “Unfortunately, Camera has stopped” error loop, where the stock camera application would crash immediately upon launch, rendering both photo and video capabilities useless. This issue, often emerging after a system update, was frequently accompanied by a baffling “Insufficient Storage” error despite ample free space and mobile data failing to work specifically on the first SIM slot. These problems pointed to severe corruption in the camera HAL, package manager cache, and modem configuration. Flashing this official V08 stock firmware is the definitive solution to reinstall the camera drivers and clear the system corruption, restoring full functionality.

Why Flash This Specific Firmware?

• Fix “Camera has stopped” Crash Loop: This is the most critical and device-specific reason for using this firmware. If your Cinemax 3’s camera app crashes on launch, flashing the V08 .pac file performs a clean installation of the camera sensor drivers (HAL) and the stock camera APK, which is the only proven method to permanently resolve this issue and restore photo and video functionality, as confirmed by user success stories.
• Resolve “Insufficient Storage” Error Despite Free Space: Address the confusing bug that prevents app installations. The firmware flash completely wipes and rebuilds the package manager and Dalvik cache, eliminating the corrupted data that causes the system to miscalculate available storage.
• Restore Mobile Data on SIM 1: Fix the specific dual-SIM bug where the first SIM slot has no internet access. This process reinstalls the modem firmware and data configuration, ensuring both SIM slots can establish a proper data connection.
• Recover from System Instability: Unbrick your device or resolve frequent freezes and crashes that are often a direct consequence of the core system service failures.

Some of the Bug / Firmware Fixes

• Firmware V08 (August 30, 2016): This build was released to directly address a critical compatibility issue between the camera HAL and the kernel, which was the root cause of the persistent “Camera has stopped” crashes that plagued earlier software versions.
• Patched the package manager service to fix a bug in the `storaged` daemon that caused it to report incorrect free space, resolving the false “Insufficient Storage” errors during app installations.
• Updated the RIL configuration for dual-SIM management to correct the priority and routing rules, ensuring mobile data works reliably on the first SIM slot when selected.
• Improved general system stability and performance for the SC7731 chipset on Android Marshmallow.
