Many owners of universal head units are faced with the fact that when the system boots, a standard splash screen with the Android logo or an abstract symbol is displayed on the screen. This looks unsightly, especially if you are striving for a holistic car interior design. Replacing the initial image is a popular request among enthusiasts who want to personalize their multimedia center. The process of installing a custom logo may vary depending on the processor model and firmware version. In some cases, it is enough to change the settings in the menu, while in others you will need to access system files through a file manager or connect to a computer. It is important to understand that incorrect actions can lead to the device becoming “bricked” or the image disappearing at startup. multimedia center.

It is important to understand that incorrect actions can lead to the device becoming bricked or the image disappearing at startup.
Determining the type of system and preparatory measures
Before you begin modifications, you need to find out what software controls your device. Universal radios often operate on the MTC, XY or ZC platforms. The image replacement method depends on the type of platform. Try to find information about the model in the section Settings → About device.
For safe operation, you will need to prepare several tools. First, make sure you have a high-quality image of your car brand logo. It must be in format PNG or JPG with a transparent background (for PNG) and the optimal resolution corresponding to the screen of your radio.
⚠️ Attention: Before any manipulations with system files, be sure to create a backup copy of the current firmware or at least copy the original logo file to an external one carrier. This will allow you to restore functionality in case of an error.
You will also need a flash drive formatted in the file system FAT32. Some systems do not read NTFS or exFAT formats at boot. Check if you have access to rights SuperUser (Root)as some methods require them to be available to write to system folders.
Replacement method through the engineering menu (Factory Settings)
The easiest and safest way to change the screensaver is to use the built-in engineering menu. This method is available on many popular platforms without the need for a computer. You need to find the item Factory settings or Factory Settings in the main settings menu.
When entering this section, the system will ask for a password. Access codes vary depending on the board manufacturer. Try entering standard combinations such as 8878, 126, 3368 or 1234. If none of the codes work, look for information on the specific model of your radio on specialized forums.
Inside the menu, find the tab responsible for appearance or loading. It may be called Logo Settings, Boot Animation or Car Logo. There is often a file selection button here. Click on it and, through the file manager, specify the path to your logo image saved on the internal memory or SD card.
- 🚗 Select an image with a resolution that is a multiple of your screen resolution (for example, 1024x600).
- ⚙️ Make sure that the file format is supported by the system (usually JPG or PNG).
- 💾 After selecting the file, click the “Apply” or “OK” button to save the changes.
After applying the settings, the system will prompt you to reboot. Agree with this action. The next time you turn on the radio you should see a new image. If the logo does not appear or is displayed incorrectly, return to the menu and try a different file format or reset the settings to factory settings.
If there is no explicit file selection button in the engineering menu, try switching the logo type from “System” to “User” or “Custom”, after which you may be able to upload your image.
Manually replacing the file via file manager
If the engineering menu does not provide the necessary functions, you will have to act manually, replacing the system file directly. To do this, you will need an advanced file manager with support for superuser rights, for example Root Explorer or RE Manager.
Open the application and go to the root directory of the system. The path to the logo file usually looks like /logo, /system/media or /data/local. Look for a file named logo.img, bootlogo.bmp or car_logo.png. The exact name depends on the firmware.
Before replacing, copy the original file to any other folder, for example, to /sdcard/backup. This is a critical step. Then delete the original file or rename it by adding the extension .bak. Copy your prepared image to this folder and rename it exactly the same as the original.
| File path | File name | Required format | Required rights |
|---|---|---|---|
| /logo | logo.img | BMP / IMG | Root |
| /system/media | bootanimation.zip | ZIP | Root |
| /data/local | car_logo.png | PNG | Root |
| /mnt/sdcard | custom_logo.jpg | JPG | Regular |
After replacing the file, you need to change the access rights (Permissions). Long tap on the file -> Access rights. Check the boxes so that the file is readable by all users (usually this rw-r--r-- or 644). Without the correct rights, the system will not be able to read the image when loading.
☑️ File replacement checklist
Using a PC and utilities to flash the logo
A more complex but reliable method involves using a computer and a specialized software This method is often used if the device's file system is write-locked or if you want to embed a logo directly into the firmware image. You will need a USB cable and drivers for your radio.
There are utilities such as MCT Tool or XY Auto Toolthat allow you to connect to the device in debugging mode. Connect the radio to the PC, activate the mode USB Debugging in the developer settings. Run the app and look for the function to download or change the logo.
adb push my_car_logo.png /system/media/bootlogo.pngadb shell chmod 644 /system/media/bootlogo.png
adb reboot
These commands entered into the ADB (Android Debug Bridge) console will automatically copy the file, set the correct permissions and reboot the device. This is a professional approach that minimizes the risk of errors when manually copying via the touch screen.
⚠️ Attention: When working with ADB and system partitions via a PC, make sure that the device battery is charged or the radio is connected to the car's on-board power supply. Turning off the power while writing a file can damage the bootloader.
Some manufacturers provide their own firmware configurators. In such apps, you can select a ready-made logo from the list or upload your own, and then upload the updated image to the device. This process takes longer, but guarantees compatibility.
What to do if after replacement there is a black screen?
If after a reboot you see a black screen instead of a logo, but the radio works (there is sound, the sensor responds), it means the file is damaged or has an unsupported format. Try booting the device into Recovery mode and restoring the original file from a backup copy, or reflash the device again.
Image requirements and optimization
The quality of the final result directly depends on the preparation of the source file. Car radio screens have specific resolutions that differ from standard monitors. The most common resolutions are 1024x600, 800x480 or 1280x720.
Use image editors such as Photoshop or GIMP to adjust the image. The logo must be centered. If the image is too large, it may be cut off or stretched, ruining the appearance. If it’s too small, it will look sloppy on a black background.
Pay attention to the color scheme. Some older displays have trouble displaying certain shades. It is better to use contrasting images. It's also important to consider the aspect ratio. If you put a square image on a wide screen without processing, it may become distorted.
- 🎨 Use PNG format with an alpha channel for a transparent background so that the logo looks organic.
- 📏 Strictly adhere to the resolution of your device's matrix to avoid pixelation.
- 💡 Avoid small details that may blend together in bright daylight.
Check the file size in bytes. An image that is too heavy can slow down the system boot process. The optimal size usually does not exceed 1-2 MB. Compressing the image without losing visible quality will help speed up the start of the radio.
The ideal logo for a car radio is a PNG image with a transparent background, a resolution exactly for the screen (for example, 1024x600) and an optimized file size.
Possible problems and their solutions
In the personalization process, users often encounter difficulties. The most common problem is that the logo does not change after all the actions. This is often due to the fact that the file was placed in the wrong directory or the system is caching an old image.
Try clearing the application and system cache. Go to Settings → Memory → Cache and delete temporary files. In some cases, a complete reset of settings helps (Factory Reset), but remember that this will delete all your data and installed applications.
Another problem is the appearance of the “No Signal” message or color distortion. This indicates a file format incompatibility. Try converting the image to BMP 24-bit or JPG with minimal compression. Different firmware requires different codecs to decode images when loading.
⚠️ Attention: Interfaces and file paths may differ depending on the version of Android and the specific modification of the board. If standard methods do not work, check the manufacturer's documentation for your specific head unit model.
If all else fails, your firmware version may have blocked the ability to change the logo by hardware. In this case, the only way out is to search and install custom firmware, in which this function is unlocked by the developer community.
FAQ: Frequently Asked Questions
Is it possible to put a video instead of an image when loading?
In standard firmware this is not possible, the system only supports static images. However, there are custom bootloaders (Boot Animations) in ZIP format that emulate videos, but their installation requires deep knowledge of the system and root access.
Is it safe to change the logo.img file?
Yes, if you saved the original. Replacing this file does not affect navigation, Bluetooth, or sound. In the worst case, you will return the old picture or get a black screen before the main interface loads.
Why does the old logo return after a reboot?
Most likely, the file has incorrect Permissions. The system cannot read the new file at startup and loads the default image from the protected partition. Check the file permissions (should be 644).
Where can I download ready-made logos for car brands?
Ready-made sets can be found on specialized forums dedicated to automotive electronics (for example, w3bsit3-dns.com in the Car Radios section). Users often share archives with logos for popular screen resolutions.
Do I need to get root access to change the logo?
Not always. If the engineering menu has a function for changing the logo, Root is not needed. If direct writing to the system folder is required /system or /logo, then superuser rights are required.
