ZTE Blade A3 (2020) Firmware Flash File Download [Stock Rom]
The ZTE Blade A3 (2020) is an entry-level smartphone offered by the carrier Telcel in Mexico. It is designed for basic functionality, running on the efficient Android 9 Pie (Go edition) to ensure a smooth experience on its limited 1GB of RAM. For users who need to resolve critical software errors, fix a device stuck in a bootloop, or restore a bricked phone, flashing the official stock firmware is the most reliable solution.
Important Note: This device is powered by a UNISOC SC9832E chipset. The restoration process requires the SPD Upgrade Tool and the firmware in `.pac` format. This will restore the official Telcel Mexico software, including all pre-installed applications and the original network lock.

How to Flash Firmware with the SPD Upgrade Tool
FAQs
Q1. Is this the same as the ZTE Blade A3 (2019) or Blade A3 Prime?
No. ZTE has released several different models under the “Blade A3” name. This firmware is specifically for the Blade A3 (2020). Using it on a different model, even with a similar name, will brick the device.
Q2. Will this firmware remove the Telcel network lock?
No. This is the official Telcel carrier firmware. Flashing it will restore the original software but will not remove or alter the SIM lock. The device will remain locked to the Telcel network in Mexico.
Q3. What is Android 9 Pie (Go edition)?
Android Go is a lightweight version of Android, specifically designed for entry-level smartphones with 1.5GB of RAM or less. It uses less storage, consumes less memory, and features special “Go” apps to ensure the device runs as smoothly as possible.
Q4. The phone’s language is in Spanish. How can I change it?
During the initial setup wizard, you can select your preferred language (`Idioma`). If you miss this step, you can change it later by going to `Configuración` (Settings) > `Sistema` (System) > `Idiomas y entrada` (Languages & input) > `Idiomas` (Languages) and adding your language.
Troubleshooting (ZTE Blade A3 2020)
- SPD Tool gets stuck at “Checking Baudrate”: This is a common connection error, usually caused by improperly installed drivers, a faulty USB cable, or not holding the correct boot key (Volume Down) when connecting the device.
- “Insufficient Storage” errors: The 1GB of RAM and 32GB of storage are limited. Android Go is designed to manage this, but you must use a microSD card for photos and media. Be very selective about the apps you install to keep the phone running smoothly.
- Phone won’t turn on after flashing: The removable battery is the first thing to check. Take it 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.
- “Sin Servicio” (No Service) or “SIM no válida” (Invalid SIM): This message is expected if you are using a SIM card from a carrier other than Telcel. The phone is network-locked.
