The Xolo Era 3X was positioned as an affordable smartphone with a substantial 3000mAh battery, targeting users seeking long-lasting battery performance in the budget segment. However, multiple users across Indian tech forums and review platforms documented recurring issues that undermined its primary selling point. According to user reports on MouthShut and GSMarena, the device suffered from rapid battery depletion where users observed the battery dropping from 100% to 90% within minutes of unplugging the charger, even without active usage. Additionally, users consistently reported extremely slow charging speeds, with the device taking 3-4 hours to reach full charge, which was significantly longer than expected for its battery capacity. This firmware package addresses these power management issues through optimized charging algorithms and improved battery calibration protocols.

Why Flash This Specific Firmware?
- Fix Rapid Battery Drain Issues: User reviews on MouthShut and GSMarena consistently reported that the battery would drop from 100% to 90% within minutes of unplugging, even without any usage. Multiple users documented losing 2-3% battery immediately after disconnecting the charger. The updated firmware includes power management optimizations to resolve these calibration-related battery drain problems.
- Resolve Extremely Slow Charging Problems: Users reported charging times of 3-4 hours for the 3000mAh battery, which was significantly slower than expected. User reviews specifically mentioned “charging takes a lot of time” and poor charger quality issues. The firmware addresses charging algorithm bugs and improves charging efficiency for more reasonable charging speeds.
- Recover from Boot Logo Hang/Bootloop: As documented in community forums and YouTube repair tutorials, the Era 3X is susceptible to bootloop issues where the device gets stuck on the Xolo logo after software modifications or failed updates. Flashing the stock firmware using SP Flash Tool is the standard recovery method for these soft brick situations.
- Eliminate System Performance Issues: User complaints included frequent hanging, lag, and apps crashing despite the 3GB RAM configuration. The stock firmware restoration eliminates corrupted system files and third-party modifications that cause performance degradation and system instability.
Some of the Bug / Firmware Fixes
- Firmware V1.0_M015 (December 12, 2017): This updated build specifically addresses the most critical user complaints about battery behavior. The firmware includes improved battery calibration algorithms to prevent the immediate 2-3% drop upon unplugging and fixes power management issues that caused rapid battery depletion during idle periods.
- Charging Speed Optimization: Resolves slow charging issues where users experienced 3-4 hour charging times. The updated charging algorithms improve power delivery efficiency and fix charging logic bugs that caused extended charging periods.
- System Stability Improvements: Addresses frequent hanging and performance issues reported in user reviews. The firmware restores proper system resource management and eliminates memory leaks that caused the device to perform poorly despite having 3GB RAM.
- Boot Logo Recovery: Reinstalls proper bootloader and system partition files to resolve bootloop issues where devices get stuck on the Xolo logo after failed modifications or updates.
- Display and Touch Responsiveness: Fixes reported issues with screen responsiveness and display calibration problems that affected user interaction with the device.
Crucial Prerequisites Before Flashing
- Backup All Data: The flashing process will completely erase your phone’s internal memory and restore factory settings.
- Charge Your Phone: Ensure battery level is at least 60% to prevent shutdown during the lengthy flashing process (1.8GB+ files).
- Install MediaTek USB Drivers: Download and install the MediaTek VCOM drivers on your Windows computer.
- Download SP Flash Tool: Obtain the latest SP Flash Tool for MediaTek devices.
- Use Quality USB Cable: Ensure you have a reliable USB cable for stable data transfer during the extended flashing process.
How to Flash the Firmware
Flashing the MediaTek firmware onto your Xolo Era 3X requires the SP Flash Tool. Follow these steps:
- Download and extract the firmware package (either M003 or M015 version) on your computer.
- Launch the SP Flash Tool on your Windows PC.
- Click “Download” tab, then click “Scatter-loading” button and select the MT6737_Android_scatter.txt file from the extracted firmware folder.
- Ensure all partitions are checked and click “Download” button in the SP Flash Tool.
- Power off your Xolo Era 3X completely and remove the battery if possible (wait 10 seconds).
- Press and hold the Volume Up button, then connect the phone to your computer via USB while continuing to hold the button.
- The tool will automatically detect the device and begin flashing. You can release the volume button once the process starts.
- Wait for the process to complete – this may take 15-25 minutes due to the large file size (1.8GB+).
- When flashing completes, you’ll see a green circle with checkmark. Disconnect the phone and restart it.
- The initial boot may take 10-15 minutes to complete the first-time setup.
