How to Flash Firmware with the SPD Upgrade Tool
FAQs
Q1. What is the difference between the Russian and Telcel Mexico firmware?
The Telcel firmware is customized for their network and includes carrier branding (like a boot logo) and pre-installed apps (bloatware). The Russian firmware is a more generic version for that region. They also have different modem configurations for their respective cellular networks.
Q2. Can I flash the Russian firmware on my Telcel phone to remove the bloatware?
This is not recommended. While it might remove the Telcel-specific apps, you will likely encounter network issues (“No Service”) due to incompatible modem files. Furthermore, the phone’s network lock will not be removed.
Q3. Is this firmware for the ZTE Blade A5 2020?
No. This firmware is strictly for the Blade A5 (2019). The 2020 model is a different device with different hardware and requires its own specific firmware. Flashing this on a 2020 model will brick it.
Q4. The SPD Upgrade Tool is stuck on “Checking Baudrate.” What does this mean?
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.
Troubleshooting (ZTE Blade A5 2019)
- PC Not Detecting Phone: This is almost always a driver issue. Ensure the SPD drivers are correctly installed. You may need to disable Driver Signature Enforcement in Windows. Also, try a different USB port and cable.
- “Invalid SIM” or “Sin Servicio” (No Service): This will happen if you use the Telcel firmware with a non-Telcel SIM. It can also happen if you flash the wrong regional firmware on your device.
- Device Stuck on Boot Logo: The first boot after flashing can take up to 15 minutes. If it is still stuck, you will need to boot into recovery mode (usually by holding Volume Up + Power from off) and perform a “Wipe data/factory reset”.
- Flashing Fails Midway: This can be caused by a loose USB connection or a corrupted download. Ensure the cable is secure. If it fails again, re-download the firmware file.
