How to Flash Firmware with the SPD Upgrade Tool
FAQs
Q1. What is Android 11 (Go edition)?
Android Go is a lightweight version of Android, specifically designed for entry-level smartphones with 2GB of RAM or less. It uses less storage, consumes less memory, and features special “Go” apps (like YouTube Go, Gallery Go) to ensure the device runs smoothly.
Q2. Can I install demanding games or apps on this phone?
Due to the 1GB of RAM and entry-level chipset, this phone is not suitable for modern, resource-heavy games or applications. It is designed for essential communication apps and utilities.
Q3. Will this firmware remove a carrier lock from a Russian carrier like MTS or Beeline?
This is a generic Russian firmware (GEN_RU) and is unlikely to remove a network lock if your device was specifically locked to one carrier. The device will likely remain locked to its original network.
Q4. The phone’s language is in Russian. How can I change it?
During the initial setup wizard, you can select your preferred language (look for Язык). If you miss this step, you can change it later by going to Настройки (Settings) > Система (System) > Язык и ввод (Language & input) > Языки (Languages) and adding your language.
Troubleshooting (ZTE Blade A31 Lite)
- SPD Tool gets stuck at “Checking Baudrate”: This is a connection error. The most common fixes are: reinstalling the SPD drivers, using a different USB port (USB 2.0 is often best), trying a new USB cable, and ensuring you press and hold the Volume Down button correctly before connecting the phone.
- “Insufficient Storage” errors: While the device has 32GB of storage, the 1GB of RAM is the main performance bottleneck. Android Go helps, but you should avoid running too many applications at once and use a microSD card for all photos and media files.
- 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.
- PC does not detect the 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. The battery-pull trick before connecting also helps ensure the device is in the right state for detection.
