How to Flash Firmware with the SPD Upgrade Tool
FAQs
Q1. Is this the same as the ZTE Blade A5 (2019/2020)?
No, this is a much older model. The Blade A5 Pro is from 2015. The newer Blade A5 (2019) and A5 (2020) are completely different phones with different hardware and newer Android versions. This firmware is not compatible with them.
Q2. Can I install modern apps on this phone after flashing?
No. This phone runs Android 5.0 Lollipop, an operating system from 2014 that is no longer supported by most modern apps. The 1GB of RAM and 8GB of storage are also far below minimum requirements. This firmware is for restoring the phone for basic functionality, not modern app usage.
Q3. Why do I get constant “Google Play Services has stopped” errors?
This is the most common problem for Android 5.x devices today. The version of Google Play Services in the firmware is obsolete. After flashing, you must connect to Wi-Fi and let the Play Store attempt to update itself and Play Services, but this may fail due to storage limitations.
Device-Specific Troubleshooting
- “Insufficient Storage” Error: The 8GB of internal storage is the biggest limitation of this phone. It is essential to use a microSD card for all photos and media. Go to `Settings > Apps` to disable any pre-installed bloatware to free up precious system space for essential updates.
- Unstable Wi-Fi Connection: This firmware restores the original, stable drivers for the Wi-Fi hardware. If you still experience issues with Wi-Fi dropping after a clean flash, try ‘forgetting’ the network and re-connecting. You can also try resetting network settings via `Settings > Backup & reset > Network settings reset`.
- Stuck on ZTE Logo (Bootloop): A bootloop is a common issue. A full firmware flash with the SPD Upgrade Tool is the most reliable solution. After flashing, the first boot can be slow. If it’s still stuck after 15 minutes, boot into recovery (hold Volume Up + Power) and perform a “Wipe data/factory reset”.
- SPD Tool is stuck on “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.
