Download Zen Admire Glam SC7731C V7 Official Firmware

The Zen Admire Glam is an Android 6.0 Marshmallow device built on the Spreadtrum SC7731C platform. A particularly frustrating issue documented by users in online communities involves the phone unexpectedly shutting down while still showing 15-30% battery remaining, often failing to power back on until plugged into a charger. This behavior strongly points to a corrupted battery calibration file within the software. Flashing this official V7 stock firmware performs a deep reset of the power management subsystem, reinstalling the original battery profiles and drivers to correct the inaccurate power level reporting and prevent premature shutdowns.

Why Flash This Specific Firmware?

• Fix Random Shutdowns & Battery Calibration: This is the most critical reason for this device. The firmware resets the Battery Management Unit (BMU) software, correcting the bug that causes the phone to power off with significant battery charge still remaining.
• Resolve Unresponsive Touchscreen After Sleep: As reported in user forums, the screen can fail to respond after waking the device. A full flash reinstalls the touchscreen driver and firmware, eliminating the software glitch that causes this “dead touch” issue.
• Unbrick a Soft-Bricked Device: If your Admire Glam is stuck on the boot logo, won’t boot into the system, or is stuck in a recovery loop, this stock ROM is the definitive tool to restore the device to a bootable state.
• Remove Persistent Software Errors: Eliminate recurring system UI crashes, “Google Play Services has stopped” errors, and other persistent software glitches by performing a clean installation of the operating system.

Some of the Bug / Firmware Fixes

• Firmware V7 (December 29, 2016): This year-end build includes a crucial patch for the kernel’s power management driver, directly addressing the battery calibration bug that led to premature and random shutdowns at reported mid-level charges.
• Reinstalls the stock touchscreen firmware, resolving the issue where the screen would become unresponsive after the device entered deep sleep, a problem repeatedly mentioned by owners.
• Fixes a wakelock issue that prevented the device from entering deep sleep mode, which contributed to faster-than-normal battery drain during idle periods.
• Addresses instability in the Wi-Fi driver that caused intermittent disconnections and difficulty reconnecting to known networks.
