How to Flash Stock Firmware on MediaTek (MTK) Smartphones
FAQs
Q1. Is this the same as the Acer Liquid Z630S?
No. This is a critical distinction. The standard Z630 (T03) uses a quad-core MT6735 chipset and has 1GB/2GB of RAM. The Z630S (T04) is a more powerful variant with an octa-core MT6753 chipset and 3GB of RAM. Their firmwares are not interchangeable and will brick the wrong device.
Q2. My 4000 mAh battery seems to drain fast or shows the wrong percentage. Will this fix it?
Yes, abnormal battery drain and incorrect percentage reporting are often caused by software bugs. A clean flash of the stock firmware will eliminate these issues and reset the battery calibration stats. After flashing, let the phone fully charge and discharge once to help the system re-learn the battery capacity.
Q3. Can I update this phone to Android Marshmallow?
No. This firmware is for Android 5.1 Lollipop. The Liquid Z630 did not receive a widespread official update to Android 6.0. This firmware will restore the original Lollipop OS.
Device-Specific Troubleshooting
- Extreme Lag and Slow Performance: A clean flash will restore the phone to its original performance. However, with 1GB or 2GB of RAM and an older chipset, the phone will always struggle with modern apps. After flashing, disable any pre-installed bloatware and use “Lite” versions of apps for the best possible experience.
- Overheating, especially during charging: The Z630 can get warm when charging its large 4000 mAh battery. A firmware flash ensures the charging process is managed correctly by the original software. If it gets excessively hot, you may be using a faulty or non-original charger/cable.
- “System UI has stopped” or Frequent Freezing: This indicates a corrupted operating system. Flashing the stock ROM using the SP Flash Tool guide is the most reliable way to fix this. The process will wipe all data but installs a fresh, stable copy of Android.
- SP Flash Tool Doesn’t Detect the Phone: This is a driver issue. Reinstall the VCOM drivers (disabling driver signature enforcement in Windows first). The removable battery is your best tool: remove it, click “Download” in SP Flash Tool, then connect the phone without the battery. Once the red bar appears, you can re-insert it.
