The Acer Liquid Z220 is an ultra-budget, compact 3G smartphone from 2015, designed as a first step into the Android world. It features a pocket-friendly 4.0-inch display and is powered by a Qualcomm Snapdragon 200 processor. This guide provides the official stock ROM for the EMEA region, 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 Z220. 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 Z220 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 Z220
- “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.
- 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.
- QFIL “Sahara” or “Firehose” Error: This error points to a communication failure. Use a high-quality USB cable, connect directly to a reliable USB 2.0 port on your computer, and try using an older, more stable version of the QFIL tool if the latest one fails.
- 3G Network Decommissioning: Be aware that the Liquid Z220 is a 3G-only device. Many mobile carriers around the world are shutting down their 3G networks. After flashing, if you have no signal, it may be because 3G service is no longer available in your area.
FAQs
Q1. Is it safe to use a phone with Android 5.0 Lollipop today?
No. Android 5.0 is extremely outdated and has not received security updates in many years. It is highly vulnerable to modern security threats. This firmware should only be used to restore the device for data recovery, offline use, or non-sensitive tasks. Do not use it for browsing, email, or any app that requires personal information.
Q2. My phone is extremely slow. Will this help?
Yes. The Z220 is a very basic device. Over time, it can become almost unusable. A full flash using this guide acts as a deep factory reset and will restore the phone to its original performance level by clearing all accumulated data.
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.
