Xolo Era 4G Firmware Flash File Download [Stock Rom]

The Xolo Era 4G is a budget smartphone built on the Spreadtrum SC9830A platform, designed to bring 4G VoLTE connectivity to the entry-level market. However, a common and significant issue reported by users on forums like GSMArena involved network problems, particularly VoLTE service dropping or becoming disabled, requiring a restart to function again. This software-level bug, often related to modem firmware, could be very frustrating for users relying on VoLTE for calls. Flashing the official stock firmware, especially the updated S204 build, is the most effective method to resolve these network stability issues by reinstalling the correct modem configuration and baseband files.

Why Flash This Specific Firmware?

• Fix VoLTE and Network Drop Issues: This is the most critical reason for flashing, especially with the S204 firmware. It updates the modem files, providing a more stable network connection and resolving the frustrating problem of VoLTE service disappearing.
• Resolve Bootloop or “Hang on Logo”: If your Xolo Era 4G is stuck on the boot screen and won’t start, a full firmware flash is the standard procedure to fix the corrupted system and unbrick the device.
• Remove Auto-Installing Malware: Some users reported issues with unwanted games and apps installing automatically. A clean flash completely wipes the device and removes any persistent malware that may have been installed.
• Improve System Performance: With only 1GB of RAM, the phone can become very slow. Reinstalling the OS removes system clutter and corrupted cache files, restoring the phone to its original, smoother performance.

Some of the Bug / Firmware Fixes

• Firmware S204 (Oct 18, 2016): This is the official Marshmallow update which, according to India Today, brought stability improvements. It contains an updated modem configuration to specifically address the VoLTE dropping issue and improve 4G network latching.
• Both firmware versions restore the original system files, fixing the software corruption that can cause the device to hang on the Xolo logo.
• Resolves issues with system services like the “Hive Launcher” crashing or stopping unexpectedly, as reported by users.
• Reinstalls a clean system partition, which is the only way to permanently remove malware that automatically downloads apps in the background.

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.
