Required Downloads: Firmware and Flash Tools

Download all the necessary files from the links below and save them in a single folder on your PC for easy access.

Important Safety Notice & Prerequisites

Your data’s safety and a successful flash depend on proper preparation. Please read the following carefully.

• Data Will Be Erased: This flashing process will completely wipe all personal data from your device. Please back up everything important.
• Charge Your Device: Ensure your phone has at least a 60% battery level to prevent it from shutting down mid-process.
• Use the Correct Files: The firmware is device-specific. Only use files designated for the Vivo Y51A.
• A Windows PC is Required: This tool is Windows-based. Ensure you have a PC or laptop available.

Step-by-Step Flashing Instructions

Step 1: Prepare Your PC and Files

To begin, you’ll need to set up your computer. Extract the contents of the downloaded Firmware, Lenovo Downloader Tool, and Qualcomm Drivers zip files into the folder you created earlier.

The first step is preparing your workspace. Unzip all three packages—the firmware, the flash tool, and the USB drivers—into a single, organized folder on your desktop.

Next, run the installer for the Qualcomm HS-USB QDLoader drivers. After the installation finishes, reboot your computer. This is a crucial step to ensure Windows can correctly recognize your phone later.

Step 2: Configure the Lenovo Downloader Tool

1. Launch the tool by double-clicking the QcomDLoader.exe file from its extracted folder.
2. Click on the first gear icon, which is the “Load” button.
3. A new window will pop up. You must navigate to and select the entire extracted firmware folder, not a specific file inside it. Click “OK”.

Step 3: Start the Flash and Connect Your Phone

This section covers the main flashing procedure. Follow the sequence carefully.

1. In the Downloader Tool, click the third icon, which is the “Start” button (it looks like a Play button). The status for all files should now show “Ready”. The tool is now armed and waiting for a device.
2. Now, put your Vivo Y51A into EDL Mode. Power off the phone completely.
3. For the Vivo Y51A (V2031), which is a Qualcomm Snapdragon 662-based device, booting into EDL (Emergency Download) mode follows a similar pattern to other Vivo phones. A direct key combination is not the standard method and will typically lead to Fastboot or Recovery mode. The most reliable and confirmed method involves a hardware-level procedure.Recommended Method: Hardware Test-Point (confirmed by repair tools like Octoplus/Hydra)
   • Process: Open the device, short the test-points on the motherboard while plugging the USB cable into a PC.
   • Result: A “Qualcomm 9008” port should appear in the computer’s Device Manager.

   Alternatives:

   • ADB: adb reboot edl (Requires USB debugging enabled on a functioning device).
   • Fastboot: fastboot oem edl (Requires an unlocked bootloader).
   • Key Combo: Holding both volume buttons during USB connection is not the confirmed method for this model to enter EDL mode.
4. While holding the required buttons, connect your phone to the PC with the USB cable.
5. The tool will automatically detect the phone in EDL mode and begin the flashing process. You will see the “Progress” bar start to fill up.
6. Once the process starts, you can let go of the buttons. Do not interrupt the process.

Step 4: Completion and First Boot

The flashing process typically takes 5-10 minutes. When it’s finished, the “Progress” bar for your device will turn green. You can now safely disconnect your phone. Hold the Power button to turn it on. The first boot will take longer than usual as it sets up the new software. Be patient, and you will soon be at the device setup screen.

Troubleshooting Common Errors

• Tool doesn’t detect the phone: This is almost always a driver or EDL mode issue. Re-install the drivers (and reboot), and double-check you are using the correct button combination to enter EDL mode. Also, try a different USB port and cable.
• “Start” button is greyed out or disabled: This means the firmware folder was not loaded correctly. Repeat Step 2 and ensure you are selecting the entire main firmware folder.
