The ZTE Blade A310 is a basic, entry-level 4G smartphone from 2016 designed for the Brazilian market. For owners of this older device, flashing the official stock firmware is the best way to resolve critical software issues, fix the common “dm-verity” error, or restore a phone that is stuck in a bootloop.
Important Note: The filename for this package is incorrectly labeled with “SPD.” The ZTE Blade A310 is powered by a Qualcomm Snapdragon 210 chipset, not a UNISOC chip. Therefore, the correct restoration process requires the QFIL tool. Following the guide for the device’s actual hardware is essential.

How to Flash Firmware on Qualcomm Smartphones with QFIL
FAQs
Q1. Why does the filename say “SPD” but the guide uses “QFIL”?
The original uploader mislabeled the file. The ZTE Blade A310 is confirmed to use a Qualcomm Snapdragon 210 chipset, which exclusively uses the QFIL tool. Following the correct guide for the phone’s actual hardware is essential to avoid flashing errors and potential damage.
Q2. Will this firmware remove the network lock from my Brazilian carrier (Vivo, TIM, Claro)?
No. This is the official stock firmware. It will restore the original software but will not remove the SIM lock. The device will remain locked to its original carrier in Brazil.
Q3. My phone is stuck at boot with a “dm-verity” error. Will this fix it?
Yes, absolutely. The “dm-verity” error means the system partition is corrupt. Flashing this full stock firmware with QFIL is the standard and most effective way to rewrite the system and resolve this specific error.
Device-Specific Troubleshooting
- “Insufficient Storage” Error: The 8GB of internal storage is the biggest limitation. It is essential to use a microSD card. Android Marshmallow has a feature called “Adoptable Storage” which allows you to format an SD card to act as internal memory. You can set this up in `Settings > Storage & USB`.
- Phone Boots up in Portuguese: This is expected for a Brazilian firmware. During the initial setup wizard, look for the language selection option (`Idioma`) to switch to English or your preferred language.
- 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.
