Xolo ZX Firmware Flash File Download [Stock Rom]

The Xolo ZX was a mid-range smartphone powered by the MediaTek Helio P22 (MT6765) chipset, notable for its dual-camera setup and “AI Studio Mode.” However, despite the marketing focus on its camera capabilities, many users on Indian e-commerce platforms and tech review sites reported disappointing results. A common complaint was that the AI portrait mode produced photos with poor edge detection, resulting in unnatural-looking blur around the subject. This software-based image processing flaw can be addressed by flashing the official stock firmware, which restores the original, factory-calibrated camera algorithms and drivers.

Why Flash This Specific Firmware?

• Fix AI Portrait Mode Camera Issues: This is the most significant reason to flash. The firmware reinstalls the original camera HAL (Hardware Abstraction Layer) and AI image processing libraries, which can correct the poor edge detection and unnatural blur in portrait shots.
• Resolve Battery Drain Problems: Many users reported faster-than-expected battery drain. This stock ROM restores the original, optimized power management profiles and kernel, fixing software bugs (wakelocks) that cause the battery to drain while idle.
• Solve Bootloop and “Hang on Logo”: If your Xolo ZX is stuck on the boot screen and won’t start, a full firmware flash using SP Flash Tool is the standard and most effective method to unbrick the device.
• Improve System Stability: A clean flash eliminates the accumulated junk files and software corruption that cause random app crashes, system freezes, and general sluggishness.

Some of the Bug / Firmware Fixes

• Firmware V1.0 (Feb 01, 2019): This factory release contains the original camera tuning parameters designed to provide accurate edge detection for the AI Studio Mode, directly addressing user complaints about blurry portrait photos.
• Restores the optimized kernel and power profiles, which rectifies the software-induced battery drain issues.
• Fixes memory management bugs in the Android 8.1 build that could cause the user interface to lag or become unresponsive.
• Reinstalls the correct modem firmware, ensuring stable 4G VoLTE connectivity and resolving intermittent signal drop issues.

Crucial Prerequisites Before Flashing

• Backup All Data: Flashing will completely erase all personal data from your phone’s internal storage.
• Charge Your Phone: Ensure your battery is charged to at least 60% to avoid shutdowns during the process.
• Install MediaTek Drivers: You must install MTK VCOM USB drivers on your Windows PC.
• Download the Flashing Tool: You will need the SP Flash Tool.
• Use a Quality USB Cable: For a stable connection, use a reliable micro USB cable.

How to Flash the Firmware

Flashing the scatter file firmware onto your Xolo ZX requires the SP Flash Tool. Follow these steps:

1. Download and extract the firmware Xolo_ZX_..._20190201.zip file on your computer.
2. Launch the SP Flash Tool application.
3. Click on the “Scatter-loading File” button and navigate to the extracted firmware folder to select the MT6765_Android_scatter.txt file.
4. Ensure the flashing mode is set to “Download Only”. Avoid using “Format All + Download” as it can erase your IMEI.
5. Click the green “Download” button at the top of the tool.
6. Power off your Xolo ZX completely.
7. Connect the phone to your computer via USB cable. The tool should detect it automatically and begin the flashing process. (If it is not detected, try connecting while holding the Volume Down button).
8. Wait for the process to complete, which will be confirmed with a large green checkmark pop-up.
9. Disconnect the phone and power it on. The first boot can take 5 to 10 minutes.
