How to Flash the Stock Firmware
Restoring a bricked ZTE Blade A310 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 ZTE Blade A310
- IGNORE “SPD” in Filename: The most important step is to ignore the ‘SPD’ label in the filename. This phone uses a Qualcomm chip. You must use Qualcomm drivers and the QFIL tool.
- “No Port Available” / Driver Issues: 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. 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.
- Brazilian Firmware: This is official firmware for the Brazilian market. Flashing it on a device from a different region may work, but could lead to network connectivity issues due to different modem configurations.
FAQs
Q1. Why does the filename say “SPD” if the phone is Qualcomm?
This is a common packing or labeling error from whoever archived the file. The device’s official hardware specifications confirm it uses a Qualcomm Snapdragon chipset, so you must use the Qualcomm tools (QFIL) and drivers, regardless of the filename.
Q2. 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, a step below fastboot, designed to recover Qualcomm devices from a “hard brick” state where they are otherwise unresponsive.
Q3. My phone is stuck on the ZTE logo. Will this fix it?
Yes. Being stuck on the logo (a “bootloop”) is a classic software problem. Flashing the stock ROM is the most reliable way to fix this issue as it completely reinstalls the phone’s operating system.
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.
