Owners of Xiaomi Redmi 9C often face the need to migrate software after buying a new device or resetting the system to factory settings. The process of migrating data can seem difficult for a beginner, but modern MIUI shells offer built-in and effective tools to solve this problem.
There are several proven ways to clone software, each with its own advantages depending on the specific situation: you can use Google cloud services, a specialized application from the manufacturer or a manual method through installation. APK-The choice of the wholesale option depends on whether the old device is working, whether there is access to the computer and how much information you need to move.
In this article, we will take a look at all the current methods, paying special attention to the nuances of the MIUI shell based on Android. We will look at how to avoid common errors when transferring data and how to ensure the security of your personal information. A critical step is to create a full backup before starting any manipulation of system files or memory partitions. This ensures that even in the event of an unexpected failure, you do not lose access to important contacts or documents.
Use of the built-in Mi Mover tool
The most efficient and quick way to transfer data between Xiaomi devices is the proprietary Mi Mover utility. This application is preinstalled in the MIUI system and optimized to work with the hardware of the MediaTek Helio G35 processor installed in the Redmi 9C. It creates a direct Wi-Fi connection between the two gadgets, which allows you to transfer data at high speed without using Internet traffic.
To get started, you need to run the app on both devices. On the new phone that will receive the data, select the Receiver role, and on the old one, select the Sender. QR-If you have code or manually connect to the network you've created, you'll have to choose the categories to copy, and you can see not only the applications, but also the system settings, messages, call logs and media.
☑️ Preparing for migration through Mi Mover
It is important to note that some system applications may not migrate due to Android security limitations. During the transfer, device screens may temporarily go out to save energy, but the process should not be interrupted. If the connection is interrupted, the utility usually suggests restarting the transfer from the stoppage, which is very convenient with a large amount of data.
⚠️ Note: When you transfer banking applications via Mi Mover, authorization data is often not stored for security reasons. You will have to re-enter every financial service by confirming your login via SMS or push notification.
Data recovery via Google Account
Google’s ecosystem provides a robust backup mechanism that is deeply integrated into the Android operating system. When you first activate the Xiaomi Redmi 9C or after resetting, the system will offer to recover data from the cloud. This method is especially convenient if you previously had a phone on pure Android or you are just used to relying on the services of the search giant.
To work, you need to make sure that the old device is synced. Go to Settings → Google → Backup and check the date of the last copy. Google Drive usually saves lists of installed applications, passwords, contacts and calendars. However, it is worth remembering that the application files (APKs) themselves do not load into the cloud, only the list is downloaded for subsequent automatic download from the Play Market.
- 📱 Open Google Settings on your old device and click “Create a copy».
- ☁️ Make sure that application data synchronization and call history are enabled.
- 🔄 On the new Redmi. 9C When you first set up, log in to the same account.
- 📥 Select the device to recover and wait until the download of the list of programs is completed.
The main disadvantage of this method is that it depends on the speed of the Internet connection. downloading tens of gigabytes of applications and data can take a considerable time, especially if you use mobile Internet. Also, not all applications support full state recovery through Google Backup, some can run as first installed.
What to do if the synchronization is suspended?
Manual installation of applications through APK-file
In situations where automatic methods do not work or you need to transfer a specific version of the program that is no longer in the official store, manual installation is used. APK-This method requires pre-preparing files on the old device or downloading them from trusted sources. 9C Aggressive security policy MIUI, This will require additional permission adjustments.
You first need to get the application installation file. On an old smartphone, you can use a file manager or special ulites to extract it. APK After transferring the file to a new phone (via Bluetooth, USB-cable or messenger, when you try to start the installer, the system will give a warning.
You'll need to allow installation from unknown sources. The path to setup is usually: Settings → Security → Privacy → Special Permissions → Install unknown applications. Here you need to find your file manager or browser and give it the appropriate permissions. Without this step, the system will block the installation.
| Parameter | Description | Recommendation |
|---|---|---|
| Source of the file | Where APK is downloaded from | Official websites only or 4PDA |
| Android version | Compatibility of OS | Check requirements in the description |
| Architecture | Processor type | Redmi 9C needs arm64-v8a |
| Digital signature | Code security | Check the antivirus before launching |
When you manually install, you have full control over the version of the software you install, which is especially true for users who need older versions of interfaces or modified applications, but remember that automatic updates in the Play Market can overwrite a manually installed version to a newer one, if you do not disable the auto-update for a particular application.
Cloning of applications within the MIUI system
One of the most important features is App Twin, which allows you to run two instances of the same application at the same time, and while it's not really copying the program to another device, it's creating a full copy of it inside the Redmi 9C system. It's extremely useful for those who use two numbers or want to separate work and personal accounts in instant messengers.
To activate this feature, go to Settings → Applications → App Cloning. The system will offer a list of supported programs, which usually includes popular messengers and social networks. After activation, a second icon of the application with a yellow badge will appear on the desktop.
It is important to understand that a cloned application takes up additional memory space and consumes RAM resources. 9C If you're an entry-level device, creating multiple clones can slow down the interface. 1-2 essential programs.
- 💬 Supported primarily WhatsApp, Telegram, Viber.
- 📷 Instagram and Facebook are also often available for cloning.
- 🎮 Gaming accounts cannot be cloned by this method without using third-party utilities.
⚠️ Note: Notifications from a cloned app may come with a delay if too many processes are running in the background. Set up the power saving mode for the clone to "No Limits" to ensure that messages are received.
Data transfer via computer and ADB
For advanced users who are not afraid of the command line, there is a method of copying applications using tools. ADB (Android Debug Bridge. This way you can pull it out. APK-file of any application directly from device to computer, and then install it on Xiaomi Redmi 9C. The method is universal and does not depend on the brand of the donor phone.
The first step is to turn on the developer mode. To do this, click 7 times on the build number in the About Phone section. Then activate the USB Debugging menu from the Developers menu. Connect the phone to your PC and type a command to get a list of packages to find the application you want.
adb shell pm list packages | grep name appendicesAfter receiving the packet name (e.g., com.example.app), use the adb pull command to extract the base packet. APK-It should be noted that modern applications often use the Split APKs (AppBundle) format, when the program consists of several files (base code, resources for language, resources for screen density). base.apk It may cause the application to fail.
💡
To work with Split APKs through a computer, it is more convenient to use graphical shells like ADB AppControl or App Backup & Restore utilities, which are able to assemble all parts of the application into one installation package.
This is an ideal method for creating an archive of rarely used but important programs. APK-You can have files on your computer for years and make sure that even if the application disappears from the store, you still have a working copy.
Solutions and optimization after the transfer
After the copying process is completed on the Xiaomi Redmi 9C, there may be a temporary decrease in performance, the system indexes files and optimizes the application database in the background, during the first hours of operation, the device can heat up more, and battery power is consumed faster - this is normal behavior.
If some apps don’t open or crash immediately after launch, try clearing their cache. Go to Settings → Apps → All apps, select the problem program and click Clear → Clear cache. Don’t confuse it with clearing data, as this will delete your correspondence and logins.
Also, check permissions. When you migrate from other versions of Android or iOS, some of the requested rights (access to microphone, geolocation, contacts) may not be transferred automatically. Go to the settings of each important application and manually issue the necessary accesses to ensure that the functionality works correctly.
💡
After mass transfer of data, be sure to restart the device, this will complete all the background integration processes and ensure the stable operation of the system in the future.
