How to install custom recavator on Xiaomi without a computer: the complete guide

Modification of the Android operating system on Xiaomi devices often begins with replacing the standard recovery menu with a more functional analogue, such as TWRP. Many users mistakenly believe that this procedure requires a personal computer, cables and specialized software like ADB or Fastboot. However, modern methods allow you to perform this operation using only the smartphone itself and additional software installed directly on the device.

Installing a custom recovery gives you access to advanced system management functions, including creating full backups, installing unofficial firmware and obtaining Root superuser rights. The process requires carefulness and strict adherence to the algorithm of actions, since interfering with the Boot or Recovery system partition carries certain risks. In this guide, we will discuss in detail how to safely prepare the device and install a modified recovery menu, bypassing the use of a PC.

Technical requirements and preparation of the device

Before you start any manipulation of system partitions, you need to make sure that your device is fully ready for the procedure. Unlocking the bootloader is a prerequisite for installing any third-party software at the system level. Without the unlocked bootloader, trying to record the image of the recovery will lead to an error or lock the device. You can check the status by holding the power and volume buttons simultaneously: if the Fastboot mode displays the word Locked, the procedure cannot be performed.

The second critical step is to accurately define your smartphone model. There are dozens of modifications in the Xiaomi, Redmi and Poco lineup, and firmware designed for one version can completely disable another. Using a TWRP image that does not match the device's code name (for example, the image firmware for the global version in Chinese) is guaranteed to cause a touchscreen or a complete "brick".

It is also necessary to ensure a stable Internet connection and high battery power. the process of downloading files and subsequent installation can take time, and interrupting the recording of data at a critical moment is unacceptable. It is recommended to charge the smartphone to a level of at least 70-80% to avoid a sudden power outage during the procedure.

• 🔓 The bootloader must be unlocked through the official Mi Unlock procedure.
• 📱 Accurate knowledge of the model code name (e.g. cepheus, raphael, vayu).
• 🔋 Battery charge must exceed 70% for safe operation.
• 💾 Free space in internal memory for storing downloaded images and backups.

⚠️ Note: You perform all actions to modify the system software at your own risk. The author is not responsible for possible data loss or device failure as a result of your actions.

File preparation is the foundation of a successful installation, and you will need to download a current.img file image that is compatible with your model, usually from official topics on the 4PDA or XDA Developers forum, and do not use files from unverified sources, as they may contain errors or malicious code.

Necessary tools and software

To implement the custom recavator task without the need for a computer, you will need a dedicated installer application. The most popular and time-tested tool is the TWRP Installer application (often referred to simply as the TWRP App), which can work with root rights that can be obtained temporarily, or use system vulnerabilities to write an image to the recovery section.

In some cases, if the direct application does not work due to the features of the Android version or the architecture of the processor, you may need to use a terminal emulator. Through the Linux command line built into Android, you can manually copy the image file to the desired partition of memory. For this purpose, the commands dd or utility are used. flash_recovery, But this method requires high qualifications.

You’ll also need a file manager with access to system folders if the installer app doesn’t have a built-in file browser. Managers like MT Manager or Solid Explorer (with root access enabled) let you move the downloaded image to the root of internal memory, where it’s easier to find when you install it.

• 📥 Annex TWRP Installer (APK-latest-version file).
• 📂 File Manager with Root Rights (e.g. Root Explorer).
• 📄 Image of Recovery twrp.img for your model.
• 🔐 Superuser rights (Magisk or analogue) if required for the installation.

Importantly, newer versions of Android (11, 12, 13 and above) have changed partition structure, and now use the dynamic recovery partition, which is part of the boot, so older direct writing methods may not work, and the installer application must support Dynamic Partitions.

Step-by-step instructions for installing TWRP

The installation process begins with the pre-installed TWRP Installer application. When you first start, the program will request superuser (Root) rights. If you already have Magisk installed, confirm access. If root is not available, some versions of the application may suggest using a system installation method that does not work on all devices.

Once you have access rights in the main menu, click the file selection button (usually marked as Select TWRP img or folder icon). In the opener, find the previously downloaded.img image file. Make sure you choose the image file rather than the.zip or.tar archive, unless the application requires a different format.

When a file is selected, a Flash to Recovery button appears on the screen. Press it. The system will warn you that changes will be made to system partitions. Confirm the action. The firmware process takes only a few seconds. Once completed, you will see a success message.

But the work doesn't end there. Xiaomi's standard procedure often overwrites custom Recovery to stock when you first boot them into the system. To avoid this, you need to press the Reboot to Recovery button right in the app immediately after you report a successful firmware. If you don't, press the volume and power button at the same time as the screen goes out.

If you see the TWRP logo and menu with Install, Wipe, Backup buttons after the reboot, congratulations, the installation was successful. Now you can use the advanced functionality. If you downloaded regular Android, then the system automatically restored the original recovery partition, and you need to repeat the procedure, paying special attention to the time of reboot.

Solving Typical Problems and Errors

One of the most common problems is cyclical reboot or inability to enter recovery mode, often because antivirus mechanisms MIUI or HyperOS block unauthorized recording, in which case pre-rename the image file or use the terminal to force write through the command dd if=/path/to/twrp.img of=/dev/block/bootdevice/by-name/recovery.

Another common error is “Touch not working” in the TWRP menu. This happens if you set the image intended for the global version to Chinese (or vice versa), since the drivers of the touch screen differ, in which case you need to find and install the TWRP image that is marked as compatible with your version of the software (Global/China/EEA).

⚠️ Warning: If after installing the recovery, the phone has stopped responding to the presses, but the vibration response and sound are present, in no case try to reflash the device chaotically.

Also, users are faced with a Failed to mount /data error, which means that they cannot access user data, which often happens when switching between different versions of Android or when encrypting data, the solution is to format the Data partition through the Wipe -> Format Data menu, but this will completely delete all files from the phone.

• ❌ Mounting error: Data formatting (data loss) is required).
• 🖐️ The Touch Doesn't Work: The Wrong Version TWRP regionally.
• 🔄 Reboot cycle: A damaged image or conflict of Android versions.
• 🔒 Locked bootloader: Installation is impossible without unlocking.

The first steps after installing a custom recavery

Once you've successfully logged in to TWRP, the first thing you should do is back up your current system. Even if you don't plan to change anything, backup of Boot, System, and Data will allow you to go back to your original state if you don't do it. Select Backup, mark the partitions you want, and swipe your finger to confirm.

Now, if you're planning to install custom firmware or get Root rights, you need to address the encryption issue. Newer versions of TWRP can work with encrypted partitions, asking for a screen unlock password when you start, and if the password doesn't fit or you've forgotten it, you won't be able to access the data without a complete reset.

💡

If you plan to get Root rights through Magisk, do not remove the original boot image right away. SD-computer or card before making any changes.

It is also worth checking the work. OTA-Custom Recovery often blocks installation of official updates “over the air” because the system detects partition integrity. To update the firmware in the future, you will most likely have to use the method of manual installation through the same menu. TWRP, downloadable ZIP-firmware archum.

An important aspect is to keep the wide-angle camera and other specific features functional. When installing custom firmware through TWRP, you sometimes need to flash additional patches or GApps to make all services work correctly. Without a PC, you can also do this by downloading the necessary zip archives directly into your phone’s memory.

Safety and return to the drainage state

Using modified software always carries potential risks. Banking applications may fail due to the detection of Root rights or unlocked bootloader. To circumvent these restrictions, the use of Magisk Hide or Zygisk modules, which hide the fact of interference with the system from the verification applications, is often required.

If you need to return the device to its original state (for example, to sell or contact a service center), you will need a stock image recovery.img. It can be extracted from the full stock firmware for your model. The return process is similar to the installation: you launch the installer application, select a stock image and flash it into the Recovery section.

⚠️ Note: When returning to the service center, be sure to block the bootloader back through Fastboot, otherwise warranty service may be denied, citing a violation of the integrity of the software.

Remember that unlocking the bootloader and installing custom software automatically voids the warranty on the device in most regions. Xiaomi service centers easily detect the fact of interference with the Device Status: Unlocked flag in Fastboot mode.
