How to Flash Stock Firmware on MediaTek (MTK) Smartphones
FAQs
Q1. Can I install modern apps on this phone after flashing?
No. This phone runs Android 5.1 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 the minimum requirements. This firmware is for restoring the phone to its original state for basic functionality.
Q2. Why do I get constant “Google Play Services has stopped” errors?
This is the most common problem for Android 5.1 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 The version of Google Play Services in the firmware is obsolete.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. Flashing this ROM provides a clean base but does not solve the fundamental issue of the OS being outdated.
Q3. Is this the same as the standard ZTE Blade L4?
No. The “Pro” version has a slightly better processor and camera compared to the standard Blade L4. The firmware is likely not interchangeable, so it’s important to use this file only for the Blade L4 Pro.
Device-Specific Troubleshooting
- “Insufficient Storage” Error: The 8GB of internal storage is extremely small. It is absolutely essential to use a microSD card for photos/videos and to go into `Settings > Apps` to disable as many pre-installed apps as possible to free up even a small amount of system space for essential updates.
- 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.
- Sudden Death / Won’t Turn On: If your phone suddenly died, a full firmware flash with SP Flash Tool is the only software solution that might revive it. If the tool can detect the phone, there is a chance of success. If it’s still dead after a successful flash, the internal storage (eMMC) has likely failed due to age and wear.
- SP Flash Tool Doesn’t Detect the Phone: This is a driver issue. Reinstall the VCOM drivers (disabling driver signature enforcement in Windows first). The removable battery is your best tool: remove it, click “Download” in SP Flash Tool, then connect the phone without the battery. Once the red bar appears, you can re-insert it.
