Important Safety Notice

• This process can be risky. Proceed at your own risk.
• Do not interrupt the process. Unplugging the phone or a power failure during the flash can permanently damage your device.
• Use the correct files. Using the wrong firmware file for your specific model can brick your phone.

Prerequisites: All Necessary Files and Tools

1. A Windows PC: SP Flash Tool is a Windows-based application.
2. USB Cable: Use a high-quality, original-style USB cable.
3. Correct Firmware: The Vivo_Y12S_V2026_PD2036_MT6765_EX_A_6.10.6_251021.zip file.
4. SP Flash Tool: Download the latest version of the “SP Flash Tool” from a reputable source.
5. MediaTek (MTK) VCOM Drivers: Your computer needs these drivers to recognize the phone in the “preloader” state.
6. MTK Auth Bypass Tool: Many newer Vivo devices have a security feature called “SLA” (Secure Boot) or “DA” (Download Agent) authentication. The SP Flash Tool may fail without a bypass tool to disable this authentication. Download a reliable MTK Auth Bypass tool.

Detailed Step-by-Step Instructions

Step 1: Prepare Your PC and Files

1. Extract the Firmware: Unzip the downloaded firmware file (Vivo_Y12S_V2026_PD2036_MT6765_EX_A_6.10.6_251021.zip). Inside, you will find several files and folders, including the “scatter file” which is a key file for SP Flash Tool. The scatter file is typically named something like MT6765_Android_scatter.txt.
2. Extract SP Flash Tool: Unzip the SP Flash Tool file. You will see a file named flash_tool.exe.
3. Install the Drivers:
   • Install the MediaTek (MTK) VCOM drivers on your PC. You might need to disable Driver Signature Enforcement in Windows to install these.
   • How to disable Driver Signature Enforcement: Go to Settings -> Update & Security -> Recovery -> Restart now under “Advanced startup.” After restarting, go to Troubleshoot -> Advanced options -> Startup Settings -> Restart. When it restarts again, press F7 to disable driver signature enforcement.

Step 2: Launch SP Flash Tool and Load Files

1. Run SP Flash Tool: Find the flash_tool.exe file in the folder you extracted and right-click it. Select “Run as administrator”.
2. Load the Scatter File: In the SP Flash Tool window, click the “Scatter-loading File” button. Navigate to the folder where you extracted the firmware and select the MT6765_Android_scatter.txt file.
3. Verify the Partitions: SP Flash Tool will now load all the firmware partitions. Make sure the checkboxes next to the partitions are all checked. Crucially, ensure the “Preloader” partition is checked. If it is unchecked, the phone may not be able to boot.
4. Select the Download Agent: On some occasions, you may need to manually load a “Download Agent” file. You can find this in the SP Flash Tool folder. It is usually named DA_SWSEC.bin or similar.

Step 3: Bypass Authentication (if required)

1. Run the Bypass Tool: Open the MTK Auth Bypass Tool you downloaded.
2. Click Bypass: Click the “Bypass” or “Auth Bypass” button within the tool.
3. Connect the Phone: Turn off your Vivo Y12S. Press and hold the Volume Up and Volume Down buttons simultaneously while connecting it to the PC via USB.
4. Check for Connection: The bypass tool should show a “Success” message, and your PC’s Device Manager should briefly show a “MediaTek Preloader” port, confirming the bypass was successful.

Step 4: Flash the Firmware

1. Configure SP Flash Tool:
   • Make sure the dropdown menu is set to “Download Only”. Do not use “Format All + Download” unless you know exactly what you are doing, as this can erase important security partitions.
   • After a successful bypass, SP Flash Tool will automatically detect the phone.
2. Start the Flash:
   • Click the “Download” button at the top of the SP Flash Tool window.
   • Turn off your Vivo Y12S completely.
   • Press and hold the Volume Up and Volume Down buttons simultaneously and connect the phone to the PC with the USB cable. You can try with just the USB cable if that doesn’t work.
   • The tool should detect the phone and the flashing process will begin automatically. You will see a yellow progress bar at the bottom of the window.
3. Complete the Process:
   • The process will take several minutes. Do not disconnect the phone.
   • When the flash is complete, a green checkmark icon with “Download OK” will appear.
   • You can now safely disconnect your phone from the PC.

Step 5: Reboot and Set Up Your Phone

1. First Boot: Press and hold the Power button to turn on your Vivo Y12S.
2. Wait for the System: The first boot after flashing can take a long time (5-10 minutes or more) as the phone rebuilds its system files.
3. Initial Setup: You will be greeted with the initial setup screen, just like a new phone. Follow the prompts to set up your device.
