The screensaver when you turn on the smartphone is the first thing the user sees before starting the operating system. Standard animation Android often seems boring or too simple to those who are used to deep personalization of their device. Many enthusiasts want to replace the manufacturer’s logo with their own or add a unique visual effect that will run every time the gadget is turned on.
Changing the boot screen —the procedure is not the most trivial and requires certain technical knowledge. Unlike changing the desktop wallpaper, here you will have to interact with system files or use special modules for root access. The process directly affects the bootloader section, so any errors can lead to the device stopping turning on.
There are several methods for implementing this task: from using ready-made themes in launchers (which work after loading) to deep modification of system images through ADB or Magisk. In this article, we will analyze all the available methods, from simple to professional, and explain how to safely replace the standard image with the desired one.
Understanding the architecture of loading animation
Before you start replacing, you need to understand what exactly is displayed on the screen. What we call the "loading screen" is technically made up of two or even three parts. First of all, the manufacturer's logo appears (for example, Samsung or Xiaomi), which is "hardwired" into the section logo or splash of the device's memory.
Then comes the animation itself. boot animation. This is a set of images and a script that is played until the system is fully initialized. The files for this animation are usually located in the directory /system/media/. It is this part that is easiest to modify without the risk of “bricking” the phone, since errors here usually only lead to the absence of a picture, but not to damage to the device.
On some devices with a locked bootloader, it is impossible to change the first logo without flashing the entire image. boot.img. However, replacing the second stage—animation Android —is available on almost any device if you have superuser rights. It is important to understand the difference between a static logo and a dynamic sequence of frames.
⚠️ Warning: Tampering with system partitions always carries a risk. Before any manipulations, be sure to create a full backup of your data (NANDroid backup) through a custom recovery, such as TWRP.
⚠️ Attention: Interfaces and file paths may differ depending on the version Android and shell of the manufacturer. Always check the current folder structure for your specific model.
Technical details of animation formats
The loading animation consists of folders part0, part1 and the desc.txt file. Images must be in PNG format, and their size must strictly correspond to the device screen resolution, otherwise the animation will be stretched or cropped.
Device preparation and necessary tools
For successful modification, you will need not only desire, but also a specific set of tools. The basic requirement for most effective methods is the presence of root access. Without them, you will not be able to write files to the protected system directory /system/media/.
If your device is not yet rooted, you will have to unlock the bootloader and install a custom recovery. This process varies from model to model: for Pixel this is done through fastboot, and for Xiaomi requires waiting and special software from the manufacturer. After obtaining superuser rights, install the manager Magisk or SuperSU.
In addition to access rights, you will need a file manager with support for working with system partitions. An excellent choice is Root Explorer or MT Manager. It would also be a good idea to have a computer with drivers installed ADB and Fastboot in case recovery via PC is required.
- 🔓 Bootloader Unlocked.
- 👑 Installed root access (Magisk/SuperSU).
- 💻 Computer with ADB and Fastboot drivers.
- 📂 Advanced file manager with root access.
☑️ Ready for modification
Replacement method via file manager (Root)
This is the most direct method that allows you to replace animation files manually. It is suitable for those who want to use their own graphics rather than ready-made themes. First you need to find the file bootanimation.zip. In most cases, it is located on the path /system/media/, but on some firmware it can be located in /oem/media/ or /product/media/.
Before replacing, the original file must be renamed or copied to a safe place, for example, in the internal memory in a folder Backup. This is critical to being able to roll back changes. Then copy your new archive bootanimation.zip to the same directory where the original was.
After copying the file, be sure to check the access rights (Permissions). The file must have rights 644 (rw-r--r--), that is, read and write for the owner and read only for the group and others. The owner and group must be set as root and root (or system depending on the OS version). Incorrect rights will result in the animation not loading.
chmod 644 /system/media/bootanimation.zip
chown root:root /system/media/bootanimation.zip
After setting the rights, simply restart your device. If you did everything correctly, you will see a new animation when you turn it on. If the phone is stuck at the logo or the download is interrupted, try booting into Recovery mode and restoring the original file from the backup.
Use the ZArchiver archiver on the phone itself to unpack and check the bootanimation.zip structure before replacing to make sure that all folders and files are in place.
Using Magisk modules for secure modifications
A more modern and secure approach is to use the system Magisk. This method is good because it does not change the system partition directly (Systemless), but replaces files on the fly during boot. This greatly simplifies the rollback process and increases system stability.
You need to find a ready-made module in the format .zip, designed for Magisk, which contains the animation you need. Such modules can often be found on forums 4PDA or XDA Developers. The downloaded file is installed through the Magisk Manager application in the "Modules" tab.
After installing the module and rebooting, the changes take effect. The advantage of this method is that when updating the system over the air (OTA), your changes are more likely to be saved, and you will not violate the integrity of the system partition, which is important for the operation of banking applications.
| Method | Complexity | Risk of blocking | Rollback option |
|---|---|---|---|
| Manual file replacement | Medium | Low (with backup) | Manual (via Recovery) |
| Magisk Module | Low | Minimum | Through the Magisk application |
| Custom Recovery | High | Medium | Through image recovery |
| Direct writing to /system | High | High | Complex |
| Launcher Themes | Very Low | None | Instant |
Using Magisk is the most recommended method for modern devices, as it retains the ability to pass SafetyNet/Play security checks Integrity.
Changing the manufacturer's logo (Splash Screen)
Replacing a static logo that appears very first (before animation Android) is a much more difficult task. This logo is not stored in the file system, but in a separate memory section, often called logo, splash or misc. Simply replacing the file will not work here.
To modify this image, you need to create a special disk image (img) that contains your image in the correct format and title. Often, utilities like LogoBuilder or specific scripts for a specific processor model (Snapdragon, MediaTek) are used for this. You must know exactly what type of processor you have.
The process usually looks like this: you extract the current partition image logo.img, convert it into a set of images, replace the desired image with your own, assemble the image back and flash it through fastboot. The command for flashing the firmware looks like fastboot flash logo logo.img.
⚠️ Attention: Incorrect flashing of the logo section may cause the screen to remain black when turned on, although the phone will work. It is very difficult to restore this partition without the original dump.
Creating your own animation from scratch
If ready-made solutions do not suit you, you can create a unique animation yourself. To do this, you will need a graphic editor (for example, Photoshop or GIMP) and an understanding of the structure of the archive bootanimation.zip. Inside the archive there must be a file desc.txtthat describes the animation parameters.
The file desc.txt contains lines with screen resolution, frame rate and paths to folders with images. Example content: w 1080 (width), h 1920 (height), f 30 (frames per second). Next come lines like p 1 0 part0, where p means part, 1 is the number of repetitions (0 means infinity), and part0 is the folder name.
Images in folders should be named sequentially (for example 00001.png, 00002.png) and have the permission specified in the description. Do not use transparency where it is not needed, and optimize the file size so that the animation does not load the processor when the system starts.
1080 1920 60p 0 0 part0
p 1 0 part1
After preparing all the files, archive the folders and desc.txt in a zip archive. Important: archiving must be done using the "Store" method (without compression), otherwise the downloader will not be able to read the files quickly enough. In most archivers, this option is called “No compression” or “Store”.
Possible problems and solutions
During the experiments, you may encounter that the phone takes longer to load than usual or the animation is simply skipped. This is often because the image file size is too large or the PNG compression format is not optimized. The system may refuse to decode heavy images at the time of initialization.
If, after replacing the animation, the device goes into a cyclic reboot (bootloop), do not panic. Boot into Recovery mode (usually by holding the Volume Up + Power buttons). If you have TWRP, go to the file manager inside the recovery, find the replaced file and delete it or restore the original from a backup.
In some cases, especially on devices with data encryption, the animation may not be displayed until you enter the PIN code. This is normal behavior due to the fact that the data partition is not yet mounted, and the system cannot access custom animation files if they are not located on the system partition.
- 🔄 Cyclic reboot: restore the original bootanimation.zip via Recovery.
- 🖼️ Black screen instead of logo: check the image format and rights access.
- ⏳ Long loading time: reduce the resolution or number of animation frames.
- 🔇 No sound: make sure that the sound files (if any) are in the correct format.
What to do if there is no backup?
If you have not made a backup of your phone does not load, try to find the original boot.img image or partition logo for your model on the forums and flash it via Fastboot.
Frequently asked questions (FAQ)
Do I need to unlock the bootloader to change the animation?
To replace the file bootanimation.zip unlocking the bootloader through root access is not necessary, only root is enough. However, to replace the first logo (splash screen), unlocking the bootloader is almost always necessary.
Will the animation be reset after a system update?
If you changed files manually in the partition /system, then when updating over the air (OTA), the changes will most likely be lost, since the system partition will be overwritten. Magisk modules can be saved, but sometimes require re-activation.
Is it possible to put a video as a download?
No, the Android bootloader does not support playing video files (mp4, avi). The animation should be presented as a sequence of static images (PNG or JPG) that quickly replace each other.
Is this safe for banking applications?
Having root access in itself can cause problems with banking applications. Using Magisk with Zygisk enabled and root hiding (DenyList) usually solves this problem, regardless of the presence of custom animations.
Where can I download ready-made animations?
The best sources are thematic threads on the 4PDA forum for your phone model or the "Android Themes" section on XDA Developers. There, users share proven files adapted for different screen resolutions.
