FAQs
Q1. Is this the same as the ZTE Blade L4 Pro?
No. The standard Blade L4 (A515) has slightly different specifications compared to the Blade L4 Pro. While they are very similar, it is always safest to use the firmware that matches your exact model name to avoid conflicts.
Q2. Why can’t I install modern apps on this phone?
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 minimum requirements. This firmware is for restoring the phone for basic calling and SMS, not for modern app usage.
Q3. My phone is stuck in a bootloop. Will this fix it?
Yes, a bootloop is a software issue that a full firmware flash can resolve. This process will erase all data but will install a fresh, working copy of the operating system, which should allow the phone to boot normally.
Device-Specific Troubleshooting
- “Google Play Services has stopped” Error: This is a very common and difficult problem on Android 5.1. After flashing, connect to Wi-Fi immediately and open the Play Store. Let it try to update Google Play Services. If it fails due to the 8GB storage limit, you must clear the cache (`Settings > Storage > Cached data`) or disable other pre-installed apps to make room.
- “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 app 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.
- 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.
