Replacing the standard manufacturer logo with your own image is a popular way to personalize an Android radio. However, the procedure requires strict adherence to formats, saving paths and technical limitations of the device. Unlike smartphones, where replacing the screensaver is done through the launcher settings, in car multimedia systems the algorithm depends on the firmware version, chipset model and even the year of manufacture of the head unit.

This article covers all stages: from preparing the image to solving typical errors like “file not found” or “unsupported format”. We will analyze the features of radio tape recorders Pioneer, Sony XAV-AX, Alpine Halo and universal Chinese devices on MTK/Rockchip, and also provide current paths to system folders for different versions of Android Auto (from 5.1 to 12). If your radio works on Joying, Atoto or Xtrons —there are also working solutions here.

1. Preparing the image: requirements for format and resolution

The first step is to create a logo that the radio can display correctly. Most Android car radios only support static images in .png or .jpgformats, but there are nuances:

  • 📏 Resolution: must match the resolution of the radio screen. For devices with 800×480 (the most common option), an image of the same size is suitable. Radio tape recorders Sony XAV-AX5000 and Pioneer AVH-X5800DAB often require 1280×720.
  • 🎨 Color scheme: use RGB 24-bit without an alpha channel (transparency is not supported by 80% of devices). For dark logos on a light background, add a stroke of a contrasting color.
  • 📁 File name: most firmwares look for a file named bootlogo.png, logo.png or startup.png. Check the exact name in the instructions for your model.
  • 🔍 Check: before saving, enlarge the image in a graphics editor to 400% - this way you will see compression artifacts that will be noticeable on the radio screen.

To create a logo free tools are suitable:

  • 🖌️ GIMP (for fine-tuning the resolution and color profile)
  • 📱 Photopea (online analogue of Photoshop, does not require installation)
  • 🎯 Canva (templates for quick design, but check the final resolution!)
⚠️ Attention: Some radios on Android 9+ block the display of logos with text or brand logos (protection against counterfeiting). If after installation the screen remains black, try replacing the image with an abstract drawing without inscriptions.

2. Determining the chipset model and Android version

The algorithm for installing the logo depends on the hardware of the radio. To find out the technical specifications:

  1. Go to Settings → About phone (or About Device).
  2. Find the lines:
    • Processor model (for example, Rockchip RK3368 or MTK8227L)
    • Android version (from 5.1 to 12)
    • Build number (for example, rk3368_box_userdebug 7.1.2)
  • If there is not enough information, use the application CPU-Z (download APK and install via USB flash drive).

    • Below is a table of compatibility of logo installation methods with popular chipsets:

    Chipset Supported Android versions Installation method Examples of models
    Rockchip (RK3368, RK3399) 5.1–10 Replacing the file in /system/media or /vendor/media Joying JY-UQ128, Atoto A6
    Mediatek (MTK8227L, MT8163) 6.0–9.0 File logo.bin in /cache or firmware via SP Flash Tool Xtrons PB7868AP, Pumpkin Android 9.0
    Qualcomm (MSM8917, MSM8937) 8.0–11 ADB commands or modified boot.img Sony XAV-AX8000, Alpine Halo9
    Allwinner (T3, H6) 7.1–10 Replacement uboot.env or firmware via PhoenixCard Eonon GA9163, Dynavin N7

    If your radio is not in the table, check the forums 4PDA or XDA-Developers on request "radio_model custom boot logo". Often, enthusiasts post ready-made logo packs and instructions for rare devices.

    💡

    If the radio on Android 10+ does not allow you to replace the logo using standard methods, try rolling back to an earlier firmware (if the manufacturer provides archives). for Sony XAV-AX3000 a working method is only available on Android 9.

    3. Preparing a USB flash drive: formatting and folder structure

    Recorders are sensitive to the file system of the drive. Use:

    • 📁 Format: FAT32 (most devices do not support exFAT or NTFS).
    • 🔄 Cluster size: 4096 bytes (standard formatting value).
    • 🚫 Prohibited: encryption, file compression, long folder names (more than 8 characters).

    Instructions for preparing a flash drive:

    1. Format the drive in FAT32 via SD Formatter or standard Windows tools (This computer → RMB on the flash drive → Format).
    2. Create a folder on the flash drive with the name android (in small letters!).
    3. Inside it there is a folder data or media (depends on the firmware, see the table below).
    4. Place the prepared logo file (bootlogo.png) in the final folder.

    Folder structure for different firmwares:

    └── (Flash drive root)

    ├── android/
    

    │ ├── data/ # For Rockchip, Allwinner
    

    │   │   └── bootlogo.png
    

    │ └── media/ # For some Mediatek
    

    │       └── logo.bin
    

    └── (additional files, if needed)

    ⚠️ Attention: Some radios (for example, Pioneer AVH-Z5200BT) require that the flash drive be connected to rear USB port (not to the front one!), otherwise the system will not see the files to update.

    FAT32 format|The android/data folder exists|The logo file is named correctly|The flash drive is connected to the correct port-->

    Universal method for most radios on Android 5.1–9.0:

    1. Turn off the radio (press the power button or remove the key from the ignition).
    2. Insert a flash drive to the USB port For devices with two ports, use the one closest to the connector. antennas (usually this is the “system” port).
    3. Turn on the radio in update mode:
      • For Rockchip: press Menu + Power for 5 seconds.
      • For Mediatek: hold Reset (with a paperclip) when turning on.
      • For Qualcomm: combination Volume Up + Power.
  • Wait until the update menu appears (usually a blue or green screen with a progress bar on some). On radio tape recorders, the process occurs automatically - just wait 2-3 minutes.
  • Reboot the device after completion (do not remove the flash drive until it is completely turned off!).

    • If the logo has not changed:

    • 🔍 Check the file name and path (for example, Joying sometimes required android/oem/logo.png).
    • 🔄 Try another USB port or flash drive (some radios do not work with USB 3.0).
    • 📋 Check the chipset model and find a specialized one instructions (see section 2).
    What to do if the radio is stuck on the logo?

    If after installation the device does not boot beyond the logo:

    1. Remove the flash drive and reboot the radio (hold the power button for 10+ seconds).

    2. If it doesn’t help, reset the settings via Reset (with a paper clip in the hole on the front panel).

    3. For devices on Rockchip try booting into recovery mode (Volume Down + Power) and select Wipe Data.

    4. As a last resort, reflash the radio via a PC (look for instructions for your model on the forums).

    5. Alternative methods for difficult cases

    If the standard method did not work, try one of these options:

    Method 1: Via ADB (for advanced users)

    Suitable for radios with debugging mode (Android Debug Bridge).

    1. Enable USB debugging in the developer settings (Settings → About phone → Build number - tap 7 times).
    2. Connect the radio to the PC via USB (use a cable that supports data transfer!).
    3. Enter in the command line: 
      adb devices

      adb shell
      

      su
      

      mount -o rw,remount /system
      

      cp /sdcard/android/data/bootlogo.png /system/media/
      

      chmod 644 /system/media/bootlogo.png
      

      reboot

    Method 2: Via firmware (for Mediatek)

    If the radio is on MTK, you can use SP Flash Tool:

    1. Download the firmware for your model and unpack it.
    2. Find the file logo.bin in the folder with the firmware and replace it with yours (rename bootlogo.png to logo.bin).
    3. Flash only LOGO via SP Flash Tool (do not touch other sections!).

    Method 3: Through applications (for Android 8+)

    Some radios support changing the logo through applications like Boot Animations (root access is required). Please note that this only works on devices with an unlocked bootloader.

    ⚠️ Attention: Using ADB or firmware may void the warranty on radios. Pioneer i Sony these methods are often blocked by the manufacturer - check compatibility in advance.

    6. Typical errors and their solutions

    Even if you follow the instructions exactly, problems may arise:

    Error Possible cause Solution
    File not found Invalid path or file name Check the folder structure (section 3). For Alpine sometimes it is required android/oem/logo/logo.png.
    The logo is displayed distorted Resolution or color profile mismatch Resave the image in RGB 24-bit without compression. For the test, use black and white. logo.
    The radio does not respond to the flash drive Wrong USB port or file system Try a different port or format the flash drive to FAT32 with a cluster size of 4096.
    After installation, the radio does not turn on The firmware file is damaged or the logo format is incorrect Reset the settings via Reset or reflash the device (section 5).
    The logo is reset after update The file was replaced in the user partition, not in the system one Repeat the installation, making sure that the file is copied to /system/media (root access is required).

    If your error is not in the table, check the update log. On some radios it is saved. in the file /cache/recovery/log. To read it:

    1. Connect the radio to the PC via ADB.
    2. Enter the command: 
      adb pull /cache/recovery/log
    3. Open the downloaded file in Notepad and find the lines with E: (errors).
    💡

    90% of errors when installing a logo are associated with incorrect image resolution or file path. Always check these parameters first!

    7. Saving the original logo and rolling back changes

    Before experimenting with the logo be sure to save the original file. This will help you get everything back if something goes wrong.

    How to make a backup:

    1. Connect the radio to the PC via ADB (section 5).
    2. Copy the original logo: 
      adb pull /system/media/bootlogo.png bootlogo_original.png
    3. Save the file to your hard drive.

    To return the original logo:

    • Place bootlogo_original.png on a flash drive in a folder android/data.
    • Repeat the installation procedure (section 4).
    • For devices with root access, you can return the file via ADB: 
      adb push bootlogo_original.png /system/media/

      adb shell chmod 644 /system/media/bootlogo_original.png
      

      adb shell mv /system/media/bootlogo_original.png /system/media/bootlogo.png

    If the radio stops turning on after changing the logo, and there is no backup:

    • Find the stock firmware for your model on the manufacturer's website or 4PDA.
    • Unpack the firmware and extract the original logo.bin/bootlogo.png.
    • Sew the logo separately via SP Flash Tool or RK Batch Tool (depending on the chipset).

    8. Additional features: animation and boot sound

    Some radios support not only static logos, but also:

    • 🎬 Animated screensavers (format .zip with a sequence of frames bootanimation.zip).
    • 🔊 Sound downloads (file bootaudio.mp3 in a folder /system/media/audio/ui).
    • 🌈 Interface themes (via applications like Substratum for devices with root).

    Requirements for an animated screensaver:

    • Format: bootanimation.zip with structure: 
      part0/ (folder with frames 001.png, 002.png,...)

      part1/ (optional, for the second part of the animation)
      

      desc.txt (file with delay settings)

    • Frame resolution: must match the screen resolution.
    • Frame rate: no more than 30 FPS (otherwise the animation will jerk).

    Example file desc.txt for smooth animation:

    480 480 24

    p 1 0 part0
    

    p 0 0 part1

    Where:

    • 480 480 — screen resolution.
    • 24 —frame rate.
    • p 1 0 part0 —play part0 1 time with a delay of 0.
    ⚠️ Attention: Animated screensavers can increase loading time radio for 5–10 seconds. On devices with a weak processor (for example, MTK8227L) this leads to delays at start.
    💡

    To create animation, use GIMP with the plugin APNG or online services like EZGIF. The optimal duration of the screensaver is 3-5 seconds.

    Is it possible to install a logo on a radio without a USB port?

    Yes, but methods differ:

    • Via Wi-Fi: copy the logo file to the radio via FTP (application FX File Explorer + plugin FTP Server).
    • Via SD card: if the radio supports memory cards, use an adapter and repeat the steps from the section 4.
    • Via OTG cable: connect the flash drive to the phone, and the phone to the radio via OTG.

    For devices without removable media (for example, Sony XAV-AX1000) only the ADB method remains (section 5).

    Why is the logo only partially displayed after installation?

    This is a typical problem when the screen resolution and image do not match. Solutions:

    1. Check the exact screen resolution through the app AIDA64 (section "Display").
    2. Open the logo in a graphic editor and crop it to the required size (tool Canvas Size).
    3. Save the file in the format PNG-24 without compression.

    If the problem persists, check if it is cropping whether the firmware flashes the logo automatically. For example, on Pioneer AVH-X3800DAB only the central part of the image size 600×360is visible, even if the screen 800×480.

    How to install a logo on a radio with Android 10+?

    On new versions of Android, manufacturers often block the replacement of the logo through standard methods. Alternatives:

    • Root access: get superuser rights through Magisk and replace the file manually.
    • Modified firmware: some custom firmware (for example, Hal9k Mod for Alpine Halo) allow you to change the logo without restrictions.
    • Applications-launchers: use Nova Launcher or Rootless Launcher to replace the screensaver (does not work on all radios).

    For Sony XAV-AX8000 and Pioneer DMH-WT8600NEX the only working method is firmware via QFil (for Qualcomm) with replacement splash.img.

    Is it possible to install GIF instead of a logo?

    No, radios do not support the format .gif for the boot logo. Alternatives:

    • APNG: some firmware on Rockchip support animated PNG (need to be renamed to bootanimation.png).
    • Bootanimation: create a ZIP animation (section 8) with a GIF effect.
    • Video screensaver: on radios with Android 9+ you can install a video in the format .mp4 as a screensaver through the app Video Wallpaper (required root).

    Please note that animation increases loading time and can lead to lags on weak devices.

    Where to download ready-made logos for the radio?

    Sources of quality blanks:

    • Forums:
      • 4PDA (section "Car radios", topics by model).
      • XDA-Developers (search for "custom bootlogo").
    • Sites:
      • DeviantArt (section "Car Wallpapers").
      • CarStyling (logos of automobile brands in high resolution).
    • Telegram channels:
      • @AndroidAutoMods —mods for car head units.
      • @CarMediaThemes —themes and logos for radios.

    Before downloading check the file resolution and format! Many “ready-made” logos have a resolution 1080×1920 (for smartphones) and are not suitable for a radio.
