The Acer Liquid Z320 (model T012) is a compact, entry-level 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 official stock ROMs, which are low-level QFIL / EDL packages, 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 Z320 (T012). The flashing process requires your phone to be in EDL Mode (9008), and the process will erase all data.

How to Flash the Stock Firmware
Restoring a bricked Acer Liquid Z320 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 Z320
- “No Port Available” / Driver Issues: This is the most common problem. 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.
- Z320 vs. Z330 Model Confusion: The Acer Liquid Z320 and Z330 are nearly identical-looking phones that share the same chipset family. However, they were often released for different carriers or with different network band support (3G vs 4G). It is always safest to flash the firmware that matches your exact model number (T012 for the Z320) to avoid any potential modem or boot issues.
- 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 Z320, 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. Which of the two firmware versions should I use?
The build `1.005.00_PA_GEN1` is labeled for the Pan-America region and is likely a more official package. The other is a generic build. It is usually best to start with the most complete and clearly labeled firmware first.
Q2. My phone is extremely slow. Will this help?
Yes. The Z320 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.
