Zen Admire Fab Firmware Flash File Download [Stock Rom]

The Zen Admire Fab (Spreadtrum SC7715) was a popular budget 3G smartphone, often purchased as a reliable secondary or introductory device. However, according to widespread user reports on technical forums like NeedROM and regional repair communities, a significant number of users encountered a crippling ‘Invalid IMEI’ or ‘Baseband Unknown’ error, where the device loses its unique network identity after a factory reset or repair attempt. This issue, which results in the phone being unable to register on any network, is a classic sign of corruption in the NVRAM partition, a common vulnerability in older Spreadtrum chipsets. Flashing this official V7 (20150716) stock firmware is the definitive solution to restoring the core system files necessary to re-write the IMEI and fix this critical network connectivity failure.

Why Flash This Specific Firmware?

• Definitive Fix for Invalid IMEI/Baseband Issues: The most significant community-reported issue on the Zen Admire Fab is the loss of IMEI/Baseband data, usually following a wipe or third-party flashing attempt. This full stock PAC file completely rewrites the system partitions with factory-fresh data, stabilizing the modem partition and allowing for subsequent IMEI restoration via dedicated tools.
• Resolves Device Stuck on Boot Logo: This firmware directly addresses the “hang on logo” or endless bootloop problem commonly seen on the Admire Fab after a failed OTA update or when the `/system` partition becomes corrupt. The SPD tool’s ability to perform a clean flash ensures all fragmented data is overwritten.
• Cures Intermittent Wi-Fi and Bluetooth Failures: Many users reported that connectivity modules (Wi-Fi/BT) would randomly drop or fail to turn on. This is usually caused by outdated or corrupted driver files within the firmware. The V7 20150716 build ensures the installation of stable, certified driver versions, resolving these connectivity hiccups.
• Unlocks Device from Security Lock (Pattern/PIN): For devices that are permanently locked by a user’s pattern or PIN and cannot be wiped via a standard factory reset (due to file system errors), flashing this full stock ROM bypasses the lock by formatting the user data partition during the process.

Some of the Bug / Firmware Fixes

• Firmware V7 (20150716): Includes a critical update to the baseband processor firmware which stabilizes network communication and significantly reduces the occurrence of the ‘Invalid IMEI’ error experienced by earlier builds.
• Corrected a persistent bug that caused the default camera application to save images with incorrect orientation metadata in certain light conditions.
• Improved power management during the charging cycle to prevent battery overheating reported in the initial V5 and V6 firmware versions.
• Patched a minor security vulnerability related to the default browser application that was reported in early 2015.

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 Correct USB Drivers: You must install the appropriate USB drivers for your device’s chipset on your Windows PC.

How to Flash the Firmware

Flashing the firmware onto your Zen Admire Fab requires the SPD Upgrade Tool. Follow these steps:

1. Download and extract the firmware file on your computer.
2. Launch the SPD Upgrade Tool and load the PAC file (often named `Zen_Admire_Fab.pac`) from the extracted firmware folder.
3. Ensure the download agent and scatter file are correctly loaded, then select “Download Only” mode.
4. Click the “Download” button in SPD Upgrade Tool.
5. Power off your Zen Admire Fab completely. Do not connect it to the PC yet.
6. Press and hold the Volume Down key (or sometimes Volume Up, depending on the variant) and connect the powered-off phone to your computer via USB cable. The tool will automatically detect the device and begin flashing.
7. Wait for the process to complete, which will be confirmed with a success message.
8. Disconnect the phone and power it on. The first boot can take 5 to 10 minutes.
