Steps to Flash Infinix X6511B Using SP Flash Tool:

Step 1: Install USB Drivers

• Install the MediaTek USB drivers on your PC so that the system can detect your Infinix phone.

Step 2: Download and Extract the Files

• Download SP Flash Tool and extract it on your PC.
• Download the official firmware (scatter file and other files) for the Infinix X6511B, and extract the ROM files.

Step 3: Open SP Flash Tool

• Open the folder where you extracted SP Flash Tool and launch the flash_tool.exe file.
• Run the tool as Administrator to avoid any permission issues.

Step 4: Load the Scatter File

• Click on Scatter-loading or the "Choose" button on the SP Flash Tool interface.
• Navigate to the folder where you extracted the firmware and select the scatter file (usually named MTxxx_Android_scatter.txt).

Step 5: Select the Flashing Options

• Once the scatter file is loaded, SP Flash Tool will automatically load all the partitions and related files for your device.
• You’ll see checkboxes for different parts like preloader, boot, recovery, system, etc.
  • If you only want to flash the system or a particular partition, uncheck the others. For a full flash, keep all options checked.

Step 6: Prepare for Flashing

• Ensure that the Download Only option is selected in the SP Flash Tool's dropdown menu (you can choose other options like Format All + Download if you want to completely format your device, but this will erase all data).

Step 7: Connect Your Device

• Power off your Infinix X6511B.
• Connect your phone to the PC via a USB cable while holding the Volume Down button (or Volume Up, depending on the device) to enter the Download Mode.
• SP Flash Tool should automatically detect your device. If not, check the USB drivers.

Step 8: Start Flashing

• Once your device is connected and recognized, click on the Download button in SP Flash Tool.
• The flashing process will begin, and you will see a progress bar indicating the status.
• Wait for the process to finish. Do not disconnect the device or interrupt the process.

Step 9: Finish and Reboot

• Once the flashing is complete, you’ll see a green checkmark in SP Flash Tool, indicating that the process was successful.
• Disconnect your phone and power it on.

Step 10: Setup Your Device

• Once your Infinix X6511B boots up, go through the initial setup process (language, Google account, etc.).

Troubleshooting Tips:

• Device Not Detected: If the device is not detected, ensure you’ve installed the correct USB drivers and try a different USB cable or port.
• Spinning or Boot Loop: If your device gets stuck in a boot loop after flashing, it could be due to an incomplete or corrupted firmware. You might need to reflash or try a different ROM.
• SP Flash Tool Not Working: Ensure you are using the latest version of SP Flash Tool and that the firmware is compatible with your device model.

Important Notes:

• Backup: Flashing will erase everything on your phone, so ensure you have a backup of your important files before proceeding.
• Official Firmware: Always use the official firmware for your device model to avoid potential issues like bricking.
• Warranty: Flashing your device may void the warranty, so consider that before proceeding.
