Zen Admire Glow Firmware Flash File Download [Stock Rom]

The Zen Admire Glow is an ultra-budget smartphone based on the Spreadtrum SC7731C chipset and a very small 1400mAh battery. Due to its extremely limited hardware, the most significant and widely reported issue from users on Indian e-commerce sites like Flipkart was exceptionally poor battery life. Many user reviews state the battery drains completely within a few hours, with one user noting a drop from “100% to 60% within 10 minutes.” This indicates severe software inefficiency. Flashing the official stock firmware is the best solution to address this, as it restores the original, lightweight operating system and removes any background processes that are causing this abnormal power consumption.

Why Flash This Specific Firmware?

• Fix Extreme Battery Drain: This is the most important reason to flash. The stock ROM is lightweight and restores the original power management profiles, resolving the software bugs that cause the tiny 1400mAh battery to drain incredibly fast.
• Resolve Bootloop or “Hang on Logo”: If your Zen Admire Glow is stuck on the Zen logo and will not boot, flashing this official .pac file is the standard method to fix the corrupted software and unbrick the phone.
• Improve Slow and Laggy Performance: With only 1GB of RAM, the phone is very susceptible to slowing down. A clean firmware installation removes all accumulated junk files and restores the phone to its original, more responsive state.
• Remove Viruses and Screen Locks: Use this firmware to completely remove any malware, adware, or bypass a forgotten screen lock (PIN, Pattern), giving you a fresh start.

Some of the Bug / Firmware Fixes

• Firmware V6 (Aug 04, 2016): This factory build is optimized for the low-spec hardware and contains the necessary power-saving configurations to maximize the life of the 1400mAh battery, directly addressing the core user complaint.
• Restores the original, stable system files, which fixes the software corruption that leads to the device freezing or getting stuck in a bootloop.
• Corrects memory management issues in the Android 5.1 build, reducing the frequency of app crashes and making the user interface feel more responsive.
• Reinstalls the original modem files, which can help improve network signal stability for calls and 3G data.

Crucial Prerequisites Before Flashing

• Backup All Data: The flashing process will completely wipe your phone’s internal memory.
• Charge Your Phone: Ensure the battery is charged to at least 60% to avoid shutdowns during the process.
• Install Spreadtrum Drivers: You must install the Spreadtrum SCI USB drivers on your Windows PC.
• Download the Flashing Tool: You will need the SPD Upgrade Tool.
• Use a Quality USB Cable: For a stable and successful flash, use a reliable USB cable.
