Personalization of a car multimedia system is not just a tribute to fashion, but a way to make the driving process more comfortable and aesthetically pleasing. Car radios Android-based ones open up wide opportunities for customization, allowing you to replace the manufacturer's standard screensaver with your own logo. This could be the emblem of your car brand, a family coat of arms, or just a beautiful image that will please the eye every time you start the engine.
However, the replacement process bootlogo (loading image) may vary depending on the device model, version of the operating system and installed launcher. Owners of Chinese head units (HU) are often faced with the fact that the standard settings do not offer such a function, requiring intervention in the system parameters. It is important to understand that incorrect actions can lead to loading failure, so the procedure must be approached responsibly.
In this article we will analyze in detail all the available methods for changing the screensaver: from simple settings in the menu to using the engineering mode and third-party applications. You'll learn what image formats are supported, how to prepare the file, and what to do if the system doesn't accept the new settings. Are you ready to transform your multimedia systeminterface? Let's get started.
Image preparation and technical requirements
Before attempting to change system settings, you must properly prepare the graphic file. Not every image is suitable for the role of a loading screen, since display resolution the car radio often differs from standard monitors. Most modern devices operate with a resolution of 1024x600 or 1280x720, but there are also more exotic options.
The ideal format for a logo is PNG with a transparent background or JPG high quality without compression artifacts. The image should be optimized to fit the screen size to avoid stretching or black margins. If you do not know the exact resolution of your screen, you can find it in the "About the device" section or using special diagnostic utilities.
- 🖼️ Use images in PNG or JPG formats for better compatibility with the firmware.
- 📏 Strictly adhere to the screen resolution (for example, 1024x600 pixels) so that the picture does not was distorted.
- 💾 Name the file in Latin letters without spaces, for example
logo.png, so that the system recognizes it correctly. - 🎨 Avoid too small details that may become indistinguishable in the bright sun.
⚠️ Attention: Using images with an excessively high resolution (4K) on weak radio processors can cause the system to freeze when loading due to insufficient RAM.
After preparing the file, copy it to the internal memory of the device or to a connected one USB flash drive. It is recommended to create a separate folder with a clear name, for example BootLogo, so as not to get confused in the file system. Make sure that the storage medium is formatted in the FAT32 file system, as this is the most universal standard for automotive electronics.
Before copying the file, check its weight - it should not exceed 2-3 MB, so as not to slow down the system initialization process.
Standard settings through the car menu
The easiest and safest way to change the screensaver is to use the built-in functions of the system. Manufacturers of some models, such as Teyes or Pumpkin, add the option to change the logo directly to the user menu. This eliminates the need to enter hidden sections and minimizes the risk of software damage.
First, go to the main device settings. This section is usually indicated by a gear icon. Look for a tab that may be called “General,” “System,” or “Personalization.” In some interfaces, such as ZLink or CarPlay mode, this function may be hidden deeper in a submenu.
If you find the “Boot image” or “Logo at startup” item, click on it. The system will prompt you to select the file source: internal memory, SD card or USB drive. Navigation is carried out using standard means file manager Android.
| GU model | Path to settings | Supported formats | Do I need a password |
|---|---|---|---|
| Teyes CC3 | Settings -> Factory -> Logo | PNG, JPG | Yes (8888) |
| Pumpkin | Car Settings -> Boot Logo | JPG only | No |
| Generic Android | Factory Settings -> Logo | PNG | Yes (1234/0000) |
| Ownice | System -> Boot Animation | All popular | Yes (126) |
After selecting a file, the system may request confirmation of the action. Click OK or Apply. In some cases, you will need to restart your device for the changes to take effect. If after the reboot you see a new image, then the procedure was successful and customization completed.
Using the engineering menu (Factory Settings)
If the regular menu does not have the required option, you will have to turn to engineering menu. This section is intended for service centers and contains in-depth equipment settings. Access to it is usually protected by a password, which differs for different chipset and firmware manufacturers.
To enter this mode, find the “About device” or “About device” item in the settings. Quickly click on the “Build Number” item 7-10 times. In some models you need to go to the Factory Settings section and enter the code. The most common passwords: 8888, 1234, 0000, 126, 3368 or 7890.
Inside the engineering menu, look for a tab named Logo, Boot or Others. The interface here is often minimalistic and can be in English or Chinese. Be extremely careful when changing other parameters in this section, as incorrect settings may interfere with the operation of touch screen or sound.
typical_passwords: 8888, 1234, 0000, 3368, 7890, 1617, 5678Select the option to load a logo from external media. Provide the path to your prepared file. After confirmation, the system may reboot automatically. If the device is frozen on a black screen for more than 5 minutes, the image format may not be suitable, and a forced reboot will be required with the button Reset.
⚠️ Attention: In the engineering menu, do not change the CAN-bus settings or screen resolution (LCD Density) if you are not sure of their value - this may make the radio inoperable.
What to do, if the password does not match?
Try to find documentation for your specific processor model (for example, Rockchip PX6 or Allwinner). Often passwords are tied specifically to the type of chipset, and not to the brand of the radio.
Changing the logo through third-party applications
For users who do not want to risk interfering with system settings, there are special applications from the store Google Play. apps like Boot Logo Changer or Logo Installer automate the process of replacing the screensaver file. However, their operation depends on the presence root access on the device.
Most car radios are supplied without root access. If your device is already rooted, installing the app will take a couple of minutes. After launch, the app will ask for permission to access system files and offer to select an image from the gallery.
- 📱 Download the application to change the logo from a trusted source.
- 🔓 Make sure that root access is activated on the device (check through the Root Checker application).
- ✅ Grant to the application necessary permissions to write to the system partition.
- 💾 Select an image and click the “Install” or “Apply” button.
If there are no root access, some applications may offer to create a configuration file that must be manually replaced through a file manager with access to system folders. This is a more complex path and requires knowledge of Android file structure. The path to the logo is often located in the directory /system/media/ or /oem/logo/.
Use of applications is only possible if you have root access, obtaining which may void the warranty on the device.
Solving common problems and errors
During the setup process, users often encounter that the logo does not change or is displayed incorrect. The most common reason is a mismatch between image resolution the physical resolution of the display matrix. If the picture is black or distorted, try changing the file size in a graphics editor on your computer.
Another problem is that the file is simply not visible in the list of available for selection. This may occur because the system file manager does not see external drives in boot mode. In this case, copy the file to the internal memory in the root directory or folder Download.
Sometimes after installing a new logo, the radio takes longer to load than usual. This is due to the fact that the system spends resources decoding the new graphics file. If the delay is critical (more than 30 seconds), it is better to return the standard screensaver.
⚠️ Attention: If after changing the logo the radio stops turning on (cyclic reboot), you need to reset to factory settings via the Reset button or reflash the device.
It is also worth considering that some firmware has a hard link between the logo and system core. In such cases, a software replacement is not possible without completely flashing the device in a modified way. Before purchasing a radio, check this feature with the seller.
☑️ Diagnosing the problem
Safety and preservation of the original firmware
Any intervention in the car software carries certain risks. Before starting any manipulations, it is strongly recommended to make a backup copy of the current configuration. This will allow you to quickly restore the system in case of an unsuccessful experiment.
Use backup applications, such as Titanium Backup (for Root) or standard cloud storage tools for user data. Save the original logo file, if extracted from the system, to your computer. This is your insurance in case you don't like the new design or cause errors.
Remember that the manufacturer's warranty may be void if traces of unauthorized modification of system files are detected. If the device is under warranty, it is better to limit yourself to the settings available in the user menu, without affecting the engineering section. Regularly update the radio firmware to the latest version by downloading it from the manufacturer’s official website. New software versions often contain bug fixes related to graphics display and can add legal ways to customize the interface. engineering section.

Frequently asked questions (FAQ)
Is it possible to put a video instead of a picture for downloading?
In standard firmware this function is usually not available, since video requires more resources for downloading decoding at startup. However, there are custom firmware and launchers that allow you to play a short video instead of a static logo, but this can slow down the turn-on of the radio.
Where can I find the password for the engineering menu for my radio?
Passwords are often universal (8888, 1234), but depend on the processor. Try entering your device model in a search engine with the entry “factory settings password”. Information can also be found on the forums of owners of specific car brands where such GUs are installed.
Why did the sound disappear after changing the logo?
Most likely, in the engineering menu you accidentally changed the settings of the audio codec or CAN-bus protocol, and not just the logo. Try resetting the factory settings (Factory Reset) through the same menu, entering the password again, but without changing other parameters.
How to return the factory logo back?
Go to the same settings section where you changed the image. Usually there is a "Default" or "Reset" button. If it is not there, simply select the original logo file that you saved earlier, or perform a full reset of the device to factory settings.
Does the logo affect the speed of the radio?
The static logo itself has virtually no effect on the performance of the system after a full boot. However, a file that is too heavy can increase the initial initialization time by 1-3 seconds, which is generally uncritical for modern hardware.
