Replacing the logo on a Chinese Android radio: 5 working methods without the risk of “scrapping”

Chinese Android radios from brands Pumpkin, Joying, Xtrons or Eonon have long gained popularity due to the combination of price and functionality. However, the standard manufacturer logo when booting the device often irritates owners - they want to see something more personalized on the screen. Replacing the boot logo (bootlogo) is possible, but requires caution: incorrect actions can lead to loss guarantee or even radio failure.

In this article we will look at all the current methods - from simple (through special applications) to advanced (firmware editing). You will learn what tools you will need, how to avoid mistakes and what to do if the logo has not changed after replacement. And also - a unique method of restoring the original logo if the radio stops loading after an unsuccessful replacement..

Important: the procedure is different for radios on chips Rockchip (RK3368, RK3399), Allwinner (T3, H6) and Qualcomm. Check your processor model in the settings (Settings → About phone → Processor model) before starting work.

1. Preparation: what you need to know before replacing the logo

Before you start replacing, check three key points:

1. Logo type. There are two types of loading screens on Chinese radios:

• 🖼️ Static logo —one image (usually in format .bmp or .png), which is displayed for 2-5 seconds when turned on.
• 🎬 Animated logo —sequence of frames (video in .mp4 or a set of .pngfiles), typical for models with Rockchip RK3399.

2. Screen resolution. Find out the exact display parameters of your radio (for example 1024×600 or 1280×720). Inconsistent resolutions will result in distorted images or a black screen. You can find information:

• 📄 In the device instructions (section "Technical Specifications").
• 🔍 through the app AIDA64 (download from APKPure, since Google Play does not have it for Android Auto).
• 📏 Empirically: take a screenshot of the desktop (hold Power + Volume Down) and look at the file resolution.

3. Backup copy of the firmware. Without it you cannot start replacing the logo! If something goes wrong, you can restore the radio. For backup use:

• 💾 Rockchip Batch Tool (for chips Rockchip).
• 💾 SP Flash Tool (for Mediatek).
• 💾 Allwinner PhoenixSuit (for Allwinner).

⚠️ Attention: On some radios (for example, Joying JY-UQ128GP) logo replacement is blocked by the manufacturer at the bootloader level. Before starting work, check whether your model supports this function - look for information on the forums 4PDA or XDA-Developers on the exact model.

2 Method 1: Replacing the logo via. BootLogo Changer application (for beginners)

The simplest method that does not require connection to a PC. Suitable for radios on Rockchip RK3368 and some models Allwinner T3. Application BootLogo Changer . The application automatically detects the screen resolution and replaces the logo without manually editing the firmware files.

Step-by-step guide:

1. Download BootLogo Changer from 4PDA (version for Android Auto).
2. Install the APK file on the radio (allow installation from unknown sources in Settings → Security).
3. Prepare a new logo image:
   • 📌 Resolution: must match the screen resolution (for example, 1024×600).
   • 📌 Format: .bmp (24-bit) or .png (without transparency).
   • 📌 Color scheme: avoid bright red and green - they may be displayed distorted.

If the logo has not changed:

• 🔄 Try a different image format (.bmp instead .png).
• 🔄 Make sure the file does not exceed 1 MB.
• 🔄 Check if your model supports this method (a list of compatible devices is in the topic on 4PDA).

3. Method 2: Manual editing of the firmware via PC (for advanced)

This method is universal and works on 90% of Chinese radios, but requires skills in working with firmware We will edit the file logo.bmp or bootanimation.zip in the image. firmware.

Required tools:

• 🖥️ PC with Windows 7/10/11.
• 🔌 USB cable (preferably the original one, included with the radio).
• 🛠️ app for working with firmware:
  • Rockchip Batch Tool (for Rockchip).
  • SP Flash Tool (for Mediatek).
  • AndroidTool (for Allwinner).
• 📁 Backup copy of the firmware (required!).
• 🖼️ New logo image in format .bmp (24-bit, uncompressed).

Instructions for radios on Rockchip (RK3368/RK3399):

1. Connect the radio to the PC in mode MaskROM (press Reset and connect USB).
2. Open Rockchip Batch Tool, click Upgrade Firmware and select the firmware file (.img).
3. In the folder with the firmware, find the file logo.bmp (usually in rockdev/Logo) and replace it with your image (necessarily with the same name!).
4. In Rockchip Batch Tool click EraseFlash, then Upgrade.
5. Wait for the firmware to complete (100%) and disconnect USB.

For radios on Allwinner (T3/H6):

1. Unpack the firmware (.img) using AndroidTool.
2. Find the file bootlogo.bmp in the folder image.
3. Replace it with your logo (the resolution must match!).
4. Assemble the firmware back and flash it through PhoenixSuit.

⚠️ Attention: If after flashing the radio does not turn on (black screen or freezing on the logo), it means that you made a mistake with the image resolution or damaged the firmware file. In this case, it is necessary to restore the original firmware via MaskROM-mode. section 6.

4 Method 3: Replacing the animated logo. (bootanimation)

On radios with Rockchip RK3399 and some models Qualcomm animation is used instead of a static logo (bootanimation.zip). It is more difficult to replace it, but the result is worth the effort - you can install your own video when loading.

What you will need:

• 🎥 Video file in format .mp4 (resolution - like the screen, duration up to 10 seconds, bitrate no higher than 2 Mbit/s).
• 🛠️ Archiver 7-Zip or WinRAR.
• 📁 File bootanimation.zip from the firmware (usually located in /system/media).

Step-by-step guide:

1. Download the original bootanimation.zip from the firmware (you can extract via Root Explorer or from a backup).
2. Unzip it inside you will see:
   • 📁 Folder part0 —contains animation frames (files 000.png, 001.png etc.).
   • 📄 File desc.txt —describes animation parameters (resolution, FPS, number repetitions).
3. Create your animation:
   • 🎬 If you want a video: convert it into a set of frames (for example, through FFmpeg with a team

     ffmpeg -i input.mp4 -vf fps=15 part0/%03d.png

     ).
   • 🖼️ If you want a slide show: prepare a series .png-files with names 000.png, 001.png etc.

1024 600 15
p 1 0 part0

If the animation does not play:

• 🔄 Check that the correct resolution is specified in desc.txt 🔄 Make sure that the files in
• 🔄 Make sure the files are in part0 named sequentially (000.png, 001.png).
• 🔄 Try reducing FPS to 10-12 frames/s.

5. Method 4: Replacing the logo via ADB (without firmware)

This method is suitable for radios with unlocked bootloader and USB debugging enabled. It does not require a complete flashing, but only gives access to some system files.

Preparation:

1. Enable Developer mode:
   • Go to Settings → About phone.
   • Click 7 times on Build number.

Replacement instructions:

1. Open the command line (Windows) or terminal (Linux/Mac) and check the connection:

   adb devices

   The serial number of the device should be displayed.

2. Download the original logo (for backup):

   adb pull /system/media/bootanimation.zip

   or for a static logo:

   adb pull /system/media/bootlogo.bmp

3. Prepare a new logo (see requirements in section 2) and place it in the folder with ADB.
4. Replace the file on the device:

   adb push new_logo.bmp /system/media/bootlogo.bmp

   or for animation:

   adb push bootanimation.zip /system/media/bootanimation.zip

5. Set the correct access rights:

   adb shell chmod 644 /system/media/bootlogo.bmp

6. Reboot the radio:

   adb reboot

⚠️ Attention: On some radios (for example, Xtrons PB7868AP) system partition /system is mounted in read-only mode. To change this, run the command:

adb shell mount -o rw,remount /system

But be careful - incorrect mounting can lead to system failure.

6. after replacement, the logo has not changed or the radio does not turn on

If after all the manipulations the logo remains the same or the radio stops loading, do not panic. In 90% of cases, the problem can be fixed.

Cause 1: The logo has not changed

• 🔍 Check that the file is replaced in the correct folder (sometimes the logo is stored in /vendor/media instead of /system/media).
• 🔍 Make sure the file name is the same as the original (for example, logo.bmpand not logo_new.bmp).
• 🔍 Try a different image format (.bmp instead .png or vice versa).
• 🔍 Restart the radio manually (hold Power for 10 seconds).

Reason 2: The radio does not turn on (black screen or freeze)

• 🛠️ Recovery via MaskROM:
  1. Disconnect all wires from the radio.
  2. Hold the button Reset (usually located on the front panel or side).
  3. Connect the USB cable to the PC (without releasing Reset).
  4. Open Rockchip Batch Tool or SP Flash Tool and flash the original firmware.

Reason 3: The logo is distorted (stretched, blurry, with artifacts)

• 🎨 The problem is the wrong resolution or color palette. Create a new logo with the following parameters:
  • Resolution: exact (for example, 1024×600, not 1024×599).
  • Format: 24-bit BMP (no compression).
  • Colors: avoid translucency and gradients.

7. Alternative methods: if all else fails

If standard methods do not work, try workarounds. They are less reliable, but sometimes they save you in hopeless situations.

Method 1: Using Launchers with a custom logo

Some launchers (for example, Nova Launcher or Apex Launcher) allow you to install your own screensavers at startup. This will not replace the boot logo, but will hide it after the system boots.

• 📱 Install the launcher from APK (Google Play is usually missing on radios).
• 🖼️ In the launcher settings, find the option Splash Screen or Boot Animation.
• 🔄 Set your image - it will be shown instead of the standard desktop.

Method 2: Replacing the logo via TWRP (if installed)

If custom recovery is installed on your radio TWRP, you can replace the logo through the file manager:

1. Boot into TWRP (usually by holding Power + Volume Up).
2. Go to Advanced → File Manager.
3. Find the logo file (/system/media/bootlogo.bmp) and replace it with yours.
4. Set permissions 644 (rw-r--r--).
5. Reboot.

Method 3: Contact the manufacturer

Some brands (for example Pumpkin) offer an official logo replacement service for an additional fee. This is safe, but requires sending the radio to a service center. The cost is from 1,500 to 3,000 rubles (depending on the model).

💡

If you are not confident in your skills, but really want to change the logo, contact a local car electronics installers. Many of them have experience working with Chinese radios and can do this for 500–1000 rubles.

8. Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when replacing the logo. Here are the most common ones and ways to prevent them:

Mistake 1: Using the wrong image format

• 🚫 What happened: The logo is not displayed or the radio does not load.
• ✅ How to avoid: Always convert the image to 24-bit BMP without compression, use PNG-8 (indexed colors).

Error 2: Resolution mismatch

• 🚫 What happened: The logo is stretched, cut off or shifted.
• ✅ How to avoid: Check the exact screen resolution through AIDA64 and create an image with the same parameters.

Error 3: Replacing a file in the wrong folder

• 🚫 What happened: The logo has not changed, although the file was replaced.
• ✅ How to avoid: Check all possible ways:

  /system/media/bootlogo.bmp
  /vendor/media/bootlogo.bmp
  /odm/media/bootlogo.bmp
  /system/media/bootanimation.zip

Error 4: Damage to the firmware during editing

• 🚫 What happened: The radio does not turn on or constantly reboots.
• ✅ How to avoid:
  • Always make a backup of the firmware before editing.
  • Do not change other files in the firmware except the logo.
  • Use proven tools (Rockchip Batch Tool, SP Flash Tool).

Error 5: Incompatibility of firmware and logo

• 🚫 What happened: The logo is displayed clumsily or the radio is slow when loading.
• ✅ How to avoid: If you updated the firmware, download the original logo from the new version and edit it, rather than using the old one.

⚠️ Attention: On radios with processors Qualcomm (for example Xtrons QS9288B) logo replacement is often blocked at the bootloader level. Before trying to edit, check if it is unlocked OEM Unlock in the developer settings. If not, unlock it, but remember that this may reset all data!

FAQ: Answers to frequently asked questions

Is it possible to return the original logo after replacement?

Yes, for this you need:

1. Restore the original firmware via Rockchip Batch Tool or SP Flash Tool.
2. Or manually replace the logo file with a saved copy (if you have a backup).

If you did not make a backup, download the original firmware for your model from the manufacturer's official website.

Will replacing the logo on a radio with Android work? 11/12?

On new versions of Android (11 and higher), manufacturers often block access to system partitions. If your radio has been updated to Android 11/12, try:

• Use ADB with rights root (if they exist). available).
• Roll back to an older firmware (for example, Android 10).
• Turn to alternative methods (for example, custom launchers).

On some models (for example, Joying JY-UQ138GP Android 11) replacing the logo is only possible through editing the firmware on a PC.

How to find the processor model in the radio if this is not indicated in the settings?
There are several ways:
• Install the application AIDA64 or CPU-Z (download APK c APKMirror or 4PDA).
• Look at the sticker on the back panel of the radio - sometimes the chip model is indicated there.
• Look under the case (carefully remove the front panel) - there is usually a processor marking on the board.
