The ZTE Blade A7 2019 is a budget-friendly smartphone that offers a modern design with a waterdrop notch display and solid performance for everyday tasks. This European variant is powered by the octa-core UNISOC SC9863A chipset. This guide provides the official stock ROM (.pac file) for the Europe/EEA variant, which is essential for unbricking the device, fixing software bugs, removing a Google FRP lock, or restoring the phone to its factory condition.
Important: This firmware is specifically for the ZTE Blade A7 2019 (European variant) which uses a UNISOC/Spreadtrum chipset. It is not compatible with the later Blade A7 2020 (which uses a MediaTek chip) or other regional variants. Flashing the wrong firmware will hard brick your phone.

How to Flash (SPD Upgrade Tool)
This method is for restoring the official stock firmware and will erase all data on your device.
- Install Drivers: Download and extract the Spreadtrum/UNISOC USB Drivers. Run the installer. You may need to disable Driver Signature Enforcement in Windows for the drivers to install correctly.
- Extract Tools & Firmware: Extract the SPD Upgrade Tool and the downloaded firmware .zip file into separate folders on your desktop. Inside the firmware folder, you will find a large .pac file.
- Launch the Tool: Open the SPD Upgrade Tool folder and run UpgradeDownload.exe as an administrator.
- Load Firmware: Click the first Gear icon (Load Packet). Navigate to the extracted firmware folder and select the .pac file. It may take a minute for the file to be loaded and verified by the tool.
- Start Flashing Process: Click the Play icon (Start Downloading). The status will change to “Waiting”.
- Connect Your Phone: Power off your ZTE Blade A7 2019 completely. Now, press and hold the Volume Down button, and while holding it, connect the phone to your PC with a USB cable.
- Begin Flashing: The tool will detect the phone, and the progress bar will start moving. You can release the Volume Down button at this point.
- Finish: The process will take several minutes. Once it’s finished, you will see a green “Passed” message. You can now disconnect your phone and power it on. The first boot may take longer than usual.
Device-Specific Troubleshooting for ZTE Blade A7 2019
- Correct Driver Installation: The most common failure point is incorrect drivers. You must install the Spreadtrum/UNISOC drivers. On modern Windows, this often requires disabling ‘Driver Signature Enforcement’ first. Your PC should recognize the phone as a ‘SPRD U2S Diag’ port when connected correctly for flashing.
- Using the “Boot Key”: To get the tool to recognize your phone, you must use the boot key. Power the phone off completely. Press and hold the Volume Down button, and while holding it, connect the phone to your PC with the USB cable. Release the button only after the flash process begins.
- Fixing Google FRP Lock: If you are locked out of your phone after a factory reset due to Google’s Factory Reset Protection (FRP), flashing this stock ROM is a common method to remove the lock. The standard flashing process will completely reset the device and the locked account.
- A7 2019 (UNISOC) vs. A7 2020 (MediaTek): Be aware that the ZTE Blade A7 2019 (SC9863A) and the Blade A7 2020 (MT6765) are different phones with different chipsets. This firmware is only for the 2019 UNISOC/Spreadtrum model and will not work on the 2020 MediaTek model.
FAQs
Q1. What is a .pac file? A .pac file is a packed firmware file used for Spreadtrum/UNISOC chipsets. It contains all the necessary partitions—system, boot, recovery, modem, etc.—in a single, integrated file for flashing with tools like the SPD Upgrade Tool.
Q2. Can I use this ROM on a non-European Blade A7 2019? It is not recommended. This firmware is specifically for the Europe/EEA region. Flashing it on a device from another region (e.g., Russia or Latin America) could cause issues with cellular network connectivity (no signal) due to different modem configurations.
Q3. Will this process erase my data? Yes. Flashing the stock ROM with the SPD Upgrade Tool will perform a full factory reset and completely wipe all personal data, apps, and settings from your device.
