The Acer Liquid Z630S (model T04) is a mid-range phablet from 2015 designed for a balanced multimedia experience. It features a large 5.5-inch HD display, a generous 4000 mAh battery for excellent endurance, and was notable for having 8MP cameras on both the front and back, enhanced with DTS Studio Sound. The “S” model is the high-performance version, powered by the octa-core MediaTek MT6753 processor with 3GB of RAM. This guide provides official stock ROMs, which are essential for unbricking the device or performing a complete factory restore.
Important: This firmware is specifically for the Acer Liquid Z630S (T04). As a MediaTek device, it requires the SP Flash Tool for flashing. Flashing this on a different model (like the standard Z630) will cause a hard brick. This process will erase all data on your device.

How to Flash the Stock Firmware
Flashing the stock ROM onto your Acer Liquid Z630S requires a Windows PC and the SP Flash Tool. The process involves installing the MediaTek VCOM drivers, loading the MT6753_Android_scatter.txt file from the firmware into the tool, and then connecting your powered-off phone to start the flash. This will completely restore your device to its original factory software.

Device-Specific Troubleshooting for Acer Liquid Z630S
- Correct Driver Installation: The most common failure point is incorrect drivers. If the tool doesn’t see your phone, you must install the MediaTek VCOM drivers, which often requires you to disable ‘Driver Signature Enforcement’ in Windows first.
- Using the “Boot Key”: To initiate the flash, power the phone off completely. Press and hold the Volume Down button, and while holding it, connect the phone to your PC. The tool should then detect it and begin the process. If Volume Down doesn’t work, try holding Volume Up.
- Fixing Google FRP Lock: If you’re locked out of your phone by Google’s Factory Reset Protection (FRP), flashing this stock ROM will perform a complete wipe and remove the locked account.
- Safer Flashing (Uncheck Preloader): For a safer flashing process that is less likely to cause a hard brick, it is highly recommended to uncheck the `preloader` partition in SP Flash Tool before clicking Download. Flashing an incorrect preloader is the most common cause of a permanently dead phone.
FAQs
Q1. What’s the main difference between the Acer Liquid Z630S and the standard Z630?
The “S” model is the high-performance version. The Z630S (this device) has an octa-core CPU, 3GB of RAM, and 32GB of storage. The standard Z630 has a quad-core CPU, 2GB of RAM, and 16GB of storage. Their firmwares are not compatible.
Q2. Which of the two firmware versions should I use?
The build 1.012.00 is the newer version and is generally the recommended choice as it may contain bug fixes and stability improvements over the older 1.011.00 build. Start with the newest version first.
Q3. What is a “scatter file”?
The scatter file (e.g., MT6753_Android_scatter.txt) is a crucial map for MediaTek firmware. It tells SP Flash Tool the name, size, and location of every partition on the device’s storage, ensuring each part of the software is flashed to the correct place.
Q4. Will this process erase my data?
Yes. Flashing the stock ROM with SP Flash Tool will perform a full factory reset and completely wipe all personal data, apps, and settings from your device.
