The Acer Liquid Z630 (model T03) is a mid-range phablet from 2015 designed for a balanced multimedia experience and exceptional battery life. 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. The device is powered by the quad-core MediaTek MT6735 processor. This guide provides the official stock ROM for the EMEA region, which is essential for unbricking the device or performing a complete factory restore.
Important: This firmware is specifically for the Acer Liquid Z630 (T03). As a MediaTek device, it requires the SP Flash Tool for flashing. Flashing this on a different model (like the Z630S) 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 Z630 requires a Windows PC and the SP Flash Tool. The process involves installing the MediaTek VCOM drivers, loading the MT6735_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 Z630
- 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.
- CRITICAL – Z630 vs Z630S Model: This firmware is only for the standard Z630 (T03) with a quad-core MT6735. It is NOT compatible with the Z630S (T04), which has an octa-core MT6753 processor, more RAM, and different hardware. Flashing the wrong firmware will cause a hard brick.
FAQs
Q1. What’s the main difference between the Acer Liquid Z630 and the Z630S?
The “S” model (Z630S / T04) is the high-performance version with an octa-core CPU, 3GB of RAM, and 32GB of storage. The standard Z630 (this device) has a quad-core CPU, 2GB of RAM, and 16GB of storage. Their firmwares are not compatible.
Q2. My phone’s battery doesn’t last as long as it used to. Will this help?
Flashing the stock ROM can solve software-related battery drain caused by rogue apps or system bugs. However, as this is an old device, the physical battery has likely degraded with age. If the drain persists after a clean flash, the battery hardware itself is probably the cause and may need replacement.
Q3. What is a “scatter file”?
The scatter file (e.g., MT6735_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.
