ZTE Blade A531 Firmware Flash File Download [Stock Rom]
The ZTE Blade A531 is a budget-friendly smartphone offered by the carrier Movistar in Peru. It runs on the lightweight Android 8.1 Oreo (Go edition), which is specifically optimized for devices with modest hardware, ensuring a smooth experience for essential tasks. If your Blade A531 is experiencing software issues, is stuck in a bootloop, or needs to be restored to its original factory state, flashing the official stock firmware is the definitive solution.
Important Note: This device is powered by a UNISOC SC7731E chipset. The flashing process requires the SPD Upgrade Tool and the firmware in .pac format. This will restore the official Movistar Peru software, including all pre-installed applications and the network lock.

How to Flash Using SPD Upgrade Tool
- Install SPD Drivers: Download and extract the SPD USB Drivers. Run the setup file to install them. On newer versions of Windows, you may need to disable Driver Signature Enforcement for the drivers to install correctly.
- Extract Files: Unzip the downloaded Firmware file (…SPD.zip) to get the firmware package, which will be a single file with a .pac extension. Also, extract the SPD Upgrade Tool to a folder on your desktop.
- Launch the Tool: Open the SPD Upgrade Tool folder and double-click UpgradeDownload.exe.
- Load Firmware Package: Click the first gear icon (Load Packet). Browse to the location of your extracted firmware and select the .pac file.
- Prepare the Phone: Power off your ZTE Blade A531. Since it has a removable battery, it is best to take it out and re-insert it to ensure a complete shutdown.
- Start Flashing: Click the “Play” icon (Start Downloading) in the tool. Then, press and hold the Volume Down button on your phone and connect it to your computer via USB cable.
- Wait for Completion: The tool will detect the phone and a blue progress bar will appear. You can release the volume button. Wait for the process to finish, which is indicated by a green “Passed” message.
- Reboot: Disconnect the phone, remove and re-insert the battery one last time, then hold the Power button to turn it on. The first boot can take several minutes.
FAQs
Q1. Will this firmware remove the Movistar Peru SIM lock?
No. This is the official Movistar carrier firmware. Flashing it will restore the original software, but the device will remain network-locked to Movistar Peru. It will not work with other carriers like Claro, Entel, or Bitel without an official unlock.
Q2. What is Android 8.1 Oreo (Go edition)?
Android Go is a lightweight version of the standard Android OS, designed by Google for entry-level smartphones with 1GB of RAM or less. It uses less storage, consumes less memory, and comes with special “Go” versions of Google apps to ensure the device runs smoothly.
Q3. The phone’s language is Spanish. How can I change it?
During the initial setup wizard, you can select your language (Idioma). If you skip this, you can change it later by going to Ajustes (Settings) > Sistema (System) > Idiomas y entradas (Languages & input) > Idiomas (Languages) and adding your preferred language.
Q4. The firmware version is V6.0 but the OS is Android 8.1. Why?
The “V6.0” is an internal build number used by ZTE or Movistar for this specific software version. It is not related to the Android version number. The operating system on the device is correctly identified as Android 8.1 Oreo (Go edition).
Troubleshooting (ZTE Blade A531)
- SPD Tool gets stuck at “Checking Baudrate”: This is a connection error. The most common fixes are: reinstalling the SPD drivers, using a different USB port (USB 2.0 is often best), trying a new USB cable, and ensuring you press and hold the Volume Down button correctly before connecting the phone.
- Phone doesn’t turn on after flashing: Since the battery is removable, this is the first thing to check. Take the battery out, re-seat it firmly, then plug the phone into a wall charger for at least 30 minutes before trying to power it on again.
- “Insufficient Storage” warnings: This is expected on a device with 16GB of storage. Use a microSD card for all your photos, videos, and music. Be very selective about the apps you install to keep the internal storage free for the system to operate.
- Movistar apps not working: After a fresh flash, connect to Wi-Fi and open the Google Play Store. The pre-installed carrier apps may need to be updated to function correctly.
