Acer Liquid Z330 (T01) Firmware Flash File Download [Stock Rom]

The Acer Liquid Z330 (model T01) is a compact, entry-level 4G smartphone from 2015 designed for basic daily use. It features a 4.5-inch display, a removable battery, and is powered by a Qualcomm Snapdragon 210 processor. This guide provides the official stock ROM, a low-level QFIL / EDL package, designed to unbrick a hard-bricked phone, resolve persistent software errors, or bypass a Google FRP lock by restoring the device to its original factory state.

Important: This is an advanced unbricking procedure. This firmware is specifically for the Acer Liquid Z330 (T01). The flashing process requires your phone to be in EDL Mode (9008), and the process will erase all data.

Unbrick Firmware (QFIL)

How to Flash the Stock Firmware

Restoring a bricked Acer Liquid Z330 requires a Windows PC and the QFIL tool. The process involves installing the correct Qualcomm drivers, forcing your phone into EDL Mode by holding Volume Up + Down and connecting the USB cable, loading the firehose programmer and XML files from the firmware, and then starting the download.

Device-Specific Troubleshooting for Acer Liquid Z330

• CRITICAL – Z330 (Qualcomm) vs. Z320 (MediaTek): Acer released two nearly identical phones. The Z330 (this device) uses a Qualcomm Snapdragon 210. The Liquid Z320 uses a MediaTek chipset. Their firmwares are completely incompatible. Flashing a Z320 ROM on this device will cause a hard brick. Verify your model number in settings or on the sticker under the battery.
• “No Port Available” / Driver Issues: If QFIL doesn’t see the “Qualcomm HS-USB QDLoader 9008” port, your drivers are not installed correctly. You must disable Driver Signature Enforcement in Windows before running the driver installer. Reboot your PC after installation and try again.
• Entering EDL Mode: Ensure the phone is completely powered off (remove and re-insert the battery). Press and hold both Volume Up and Volume Down buttons simultaneously. While holding them, plug the USB cable into the phone. The screen will stay black, but your PC should make a sound, and the port will appear in QFIL.
• Using an Older QFIL Tool: For a classic device like the Liquid Z330, the latest versions of QPST might have issues. If you encounter errors like ‘Sahara Fail’ or ‘Firehose Fail’, try using a stable, older version of the tool in conjunction with the correct drivers.

FAQs

Q1. How do I know if I have the Z330 (Qualcomm) or Z320 (MediaTek)?
The most reliable way is to check the sticker under the battery for the model number “T01” (for Z330) or “T02” (for Z320). If the phone boots, you can also check the CPU information in the “About phone” section of the settings.

Q2. My phone is extremely slow. Will this help?
Yes. The Z330 is a very basic device. Over time, it can slow down significantly. A full flash using this guide acts as a deep factory reset and will restore the phone to its original performance level.

Q3. What is a QFIL / EDL firmware?
QFIL (Qualcomm Flash Image Loader) is a tool used to flash firmware in EDL (Emergency Download) mode. This is a very low-level mode designed to recover Qualcomm devices from a “hard brick” state where they are otherwise unresponsive.

Q4. Will this process erase my data?
Yes. A QFIL flash is a complete factory restore that erases all user data from the phone’s internal storage.
