ZTE Blade L111 Firmware Flash File Download [Stock Rom]
The ZTE Blade L111 is an ultra-low-end smartphone from 2016, designed to serve as a very basic communication device for first-time users. With its extremely modest hardware, including just 512MB of RAM, software issues can easily render it unusable. Flashing the original stock firmware is the most effective way to fix bootloops, remove viruses, or restore the phone to its out-of-the-box condition.
Important Note: This device is powered by a Spreadtrum SC7731G chipset and runs the very old Android 5.1 Lollipop. The flashing process requires the SPD Upgrade Tool and a firmware file in .pac format. Restoring this firmware will return the phone to its original, limited state.

How to Flash Using SPD Upgrade Tool
- Install Drivers: Download and extract the SPD USB Drivers. Install them on your PC. On modern versions of Windows, you may need to disable Driver Signature Enforcement first.
- Extract Files: Unzip the downloaded Firmware file (…SPD.zip) to get the firmware with a .pac extension. Extract the SPD Upgrade Tool to a separate folder.
- Launch SPD Tool: Open the tool folder and run the UpgradeDownload.exe application.
- Load Firmware Package: Click the first gear icon (Load Packet). Navigate to and select the .pac file you extracted. The tool will take a moment to load and verify the file.
- Prepare the Phone: Power off your ZTE Blade L111. Remove the back cover and take the battery out, then put it back in to ensure it is completely powered down.
- Start the Flash: Click the “Play” icon (Start Downloading) in the tool. Press and hold the Volume Down button on your phone and immediately connect it to your PC with a USB cable.
- Wait for Completion: The tool will detect the phone and a progress bar will appear. You can release the volume button. Wait until the process is finished and a green “Passed” message is displayed.
- Reboot: Disconnect the phone, remove and re-insert the battery, then hold the Power button to turn it on. The first boot after flashing will be slow.
FAQs
Q1. Can I install and run modern apps like WhatsApp or Facebook on this phone?
No. The ZTE Blade L111’s 512MB of RAM and old Android 5.1 OS are not sufficient to run almost any modern applications. This phone is only suitable for basic calling, SMS, and possibly very lightweight, older apps. Please set your expectations accordingly.
Q2. Can this phone be updated to a newer Android version like Nougat or Oreo?
No. Official software support for this device ended with Android 5.1. There are no official updates, and due to the obscure Spreadtrum chipset and low specs, no custom ROMs are available.
Q3. The phone says “Insufficient Storage” right after setup. Why?
The device has only 4GB of internal storage, of which the Android operating system itself uses more than half. This leaves very little space for apps or user data. You must use a microSD card to store any photos, music, or other files.
Q4. What is the main purpose of flashing this firmware?
The primary purpose is restoration. This firmware is for users whose device is stuck on the ZTE logo (bootloop), has been infected with malware that is hard to remove, or has become extremely slow due to software corruption. It returns the phone to a clean, factory state.
Troubleshooting (ZTE Blade L111)
- Phone Not Detected by PC: This is a driver issue. Ensure you have installed the SPD drivers correctly. Disabling Driver Signature Enforcement in Windows is often required. Also, check that you are holding the Volume Down button firmly before you plug in the USB cable.
- SPD Tool is Stuck on “Checking Baudrate”: This indicates a failed connection. Use a different USB port (preferably a USB 2.0 port), try another USB cable, and re-confirm the driver installation.
- Stuck on ZTE Logo After Flashing: The first boot can take over 10 minutes. If it is still stuck, boot into recovery mode (hold Volume Up + Power from off state) and perform a wipe data/factory reset. This will resolve the issue but will erase any data you had on the phone.
- Extremely Slow Performance: This is the normal operating condition for this phone. To make it as usable as possible, disable any pre-installed apps you don’t need (like Google Play Movies, etc.) and avoid running more than one application at a time.
