Step 2: Prepare Your Logo Image

Requirements:

  • Format: BMP

  • File name: logo.bmp

  • Recommended resolution: 1024 × 600 pixels

    • (Other resolutions may also work depending on the screen version.)

Step 3: Prepare a USB Drive

  1. Format a USB flash drive.
  2. Copy the downloaded update files to the root directory of the USB drive.
  3. Copy your customized logo.bmp file to the root directory as well.

The USB drive should contain:

USB Drive
├── update files
└── logo.bmp

Step 4: Install the New Logo

  1. Start the vehicle and power on the C12.
  2. Insert the USB drive into the C12 USB port.
  3. The system will automatically detect the update package.
  4. When the update prompt appears, click Start Update.
  5. Wait for the process to complete and the unit to reboot.

Notes

  • The image must be in BMP format and named exactly logo.bmp.
  • Do not disconnect power during the update process.
  • If the update prompt does not appear, verify that the correct update package was downloaded for your hardware version and that the files are located in the root directory of the USB drive.

Enjoy your personalized startup logo!

Has anyone had success in changing the Android Boot logo following these directions? I downloaded the correct update package (6315) based on my C12 unit and added a Toyota logo BMP file with no results. The C12 unit sees the update file when viewed through file explorer, but nothing happens.

My CPU version says 7865 and the files you have available are 7862 and 7870.

Does the 7862-update file work for the 7865 CPU?
