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. For owners of this very old device, flashing the official stock firmware is often the only way to resolve deep software corruption, fix a device that is stuck on the Acer logo, or restore it to its original factory condition.
Important Note: This device is powered by a Qualcomm Snapdragon 210 chipset and runs the outdated Android 5.1 Lollipop. The restoration process requires the use of the QFIL (Qualcomm Flash Image Loader) tool.

How to Flash Firmware on Qualcomm Smartphones with QFIL
FAQs
Q1. Can I install modern apps on this phone after flashing?
No. This phone runs Android 5.1 Lollipop, an operating system from 2014 that is no longer supported by most modern apps. The 1GB of RAM and 8GB of storage are also far below minimum requirements. This firmware is for restoring the phone for basic calling and SMS.
Q2. Why do I get constant “Google Play Services has stopped” errors?
This is the most common problem for Android 5.1 devices today. The version of Google Play Services in the firmware is obsolete. After flashing, you must connect to Wi-Fi and let the Play Store attempt to update itself and Play Services, but this may fail due to storage limitations.
Q3. Is this the same as the Acer Liquid M330?
They are companion devices. The Z330 (T01) runs Android. The M330 is the Windows 10 Mobile version of the same hardware. Their firmwares are completely different and absolutely not interchangeable.
Device-Specific Troubleshooting
- Stuck on Acer Logo (Bootloop): A bootloop is the most common reason to flash this firmware. A full flash with QFIL will erase all data but install a fresh, working copy of the OS. After flashing, the first boot can be slow. If it’s still stuck after 15 minutes, boot into recovery (hold Volume Up + Power) and perform a “Wipe data/factory reset”.
- “Insufficient Storage” Error: The 8GB of internal storage is the biggest limitation of this phone. It is essential to use a microSD card for all photos and media. Go to `Settings > Apps` to disable any pre-installed bloatware to free up precious system space for essential app updates.
- QFIL Fails with a “Sahara/Firehose” Error: This classic QFIL error points to a communication failure, usually caused by a driver problem. Reinstall the Qualcomm 9008 drivers (disabling driver signature enforcement in Windows first). The removable battery helps: remove it, enter EDL mode, then connect the phone.
- Phone Not Charging or Charging Very Slowly: On a device this old, charging issues are often hardware-related (a worn-out micro-USB port or a degraded battery). A firmware flash can fix software bugs that prevent charging, but if the problem persists after a clean flash, the hardware is likely the cause.
