Many users are faced with a situation where the standard procedure for installing a custom TWRP recavator on Xiaomi smartphones is suddenly interrupted or ended in error. Instead of the expected reboot in a modified recovery environment, the device continues to load into the standard Mi Recovery or, worse, goes into an endless cycle of reboots, this is not due to the malfunction of the smartphone itself, but due to the strict security measures implemented by the manufacturer and the features of the Fastboot protocol.
The main reason is the bootloader protection system and the integrity of the system partition. If you try to flash an image without first unlocking or use an incompatible version of a file, the process will be rejected at the hardware controller level. Understanding these mechanisms is critical, because blindly repeating actions without analyzing logs can lead to more serious software problems.
In this article, we will take a look at all possible installation failure scenarios, from simple driver errors to complex cases of Anti-Rollback protection, and learn how to interpret command-line error codes correctly and understand why your model may require a specific approach to modifying the boot image.
Problems with unlocking the bootloader (Bootloader)
The most common reason why TWRP is not installed on Xiaomi devices is a blocked bootloader.The company requires mandatory unlocking through the official Mi Unlock service, and trying to ignore this step will lead to an immediate system failure. Even if you have superuser rights, without unlocked Bootloader, writing to the recovery section is impossible.
Often users forget that once unlocked, the device automatically performs a full Wipe Data reset. If you missed this step or the process went wrong, the status of the bootloader may remain uncertain.
⚠️ Note: If the bootloader status is displayed as “Locked” in Fastboot mode, any attempts to record the image TWRP through ADB First, make sure that the status bar has an orange "Unlocked" indicator on it".
It is important to check whether Find Device is activated in your Mi Account settings. When protected, the system can block critical partitions from changing even when the bootloader is unlocked. Disable this option in the Mi acc settings menu and double-check the status before you try again.

Recovery Image and Model Compatibility Errors
The second most common cause of failure is the use of the wrong image file.img. Xiaomi’s ecosystem is huge, and even a minimal difference in the revision of the screen, processor or Android version can make the image incompatible. Trying to install the recovery designed for the global version on the Chinese (CN) version often leads to the error “Invalid image” or “Signature failed verification”.
Special attention should be paid to the processor architecture and partition type. Modern devices use partition schema. A/B, which requires the firmware of both slots (boot_a and boot_b). If you are flashing only one slot or using the image for single partition devices (A-only), the system will not be able to find the bootloader and will return to the drain state.
How to check the compatibility of the image?
Open the image file in the text editor (first lines) or examine the file name. Usually, it shows the model (for example, 'cepheus' for Mi 9) and the Android version. TWRP Lower than your phone, the installation may pass, but access to the data will be impossible due to encryption.> Also critical is the Android version. Image TWRP, The Android 10 version may not work properly or even run on Android 13 due to changes in the encryption structure and boot image format. XDA Developers or teamwin.me, avoiding questionable file exchangers.Driver problems ADB Fastboot on PC Often the problem lies not in the phone, but in the computer. If drivers ADB and Fastboot is installed incorrectly or conflicts with other versions, the firmware command simply won't reach the device. In Windows Device Manager, this can appear as "Unknown Device" or "QHSUSB_BULK" (in case of emergency mode), which makes it impossible to use standard firmware. USB-cable supplied with the device and connect it directly to the motherboard port (on the back of the PC), bypassing USB-Cheap cables often only support charging and don't transmit data, leading to a connection timeout.Reinstall drivers using the official Xiaomi package is recommended USB Drivers or Universal Google Drivers. After installing the drivers, be sure to follow the connection check command: fastboot devices If you see the serial number of the device in response, then the connection is established. If the list is empty, the problem is in the drivers or the cable. It is also worth trying to disable driver signature verification in Windows if the system blocks their installation. ☑️ Connection Diagnostics Installed by Xiaomi ADB Driver Uses Original Cable Port USB 2.0/3.0 Device Manager No Errors Team fastboot devices issues serial number: 0 / 5 Features of encryption and data formatting Modern versions MIUI And HyperOS uses complex encryption algorithms by default. TWRP Without pre-formatting the data partition (Data Wipe), the recovery will not be able to decrypt the internal memory. You'll see either a blank list of files or persistent requests for a password that isn't being accepted. It's not an installation error, it's a security mechanism. To get TWRP full access to the file system, you'll need to run a formatting command in Fastboot mode or via the Wipe menu in the recovery itself (if it allows it). However, simple cleaning (Wipe) isn't enough -- it requires Format Data. Follow the following command in Fastboot mode to force format: fastboot erasedata After that, when the first TWRP runs, the system will create a new file system without encryption or with a new key, although the user doesn't just think that partitioning is working, "And the user doesn't see why it does not allow it to edit it. Type of cleaning that does not need to be done TWRP Wipe Data Deletes files but retains encryption structure No (not enough) Format Data Completely erases partition and creates a new FS Yes (required) Factory Reset Standard reset via settings No Wipe Cache Clears temporary files Preferably Anti-Rollback protection and lock OEM One of the most important reasons for this is the Anti-Rollback mechanism (ARB). Xiaomi is implementing rollback protection that prohibits installing older versions of the bootloader or Recovery than those currently installed. TWRP, based on the old base, the device can lock at the bootloader level, and the developer settings must activate the option. OEM Unlocking. If this switch is turned off, the unlock or firmware command will be ignored. On some devices, this option becomes available only after connecting to Wi-Fi and waiting 7 days from the moment of attaching an account. ⚠️ Warning: Attempting to bypass Anti-Rollback protection can cause the device to "brick" (Hard Brick), when the phone will not respond even to the on button. ARB Check the current level of Anti-Rollback through the command in Fastboot: fastboot getvar anti If the value is high, make sure that the image used TWRP If you do not, the installation will be interrupted with the error "Anti-rollback check failed". First, return the device to a stock state to eliminate the impact of residual files. Then check the integrity of the image. TWRP (It is desirable to verify the checksum MD5). Try using an alternative installation method, for example, through the Flashify app (if there is Root) or the XiaomiTool utility. V2, It automates many processes and can bypass some software blocks. USB-port or other computer to rule out hardware conflicts. In case of persistent errors, when the phone goes into a cyclic restart (bootloop) after trying to install, press the volume down and power button to log in to Fastboot, and then execute the command fastboot reboot or restore the stock image via the Mi Flash Tool. 💡90% of installation problems TWRP So, you can do this by unlocking the bootloader properly and formatting the Data partition. Don't ignore these two steps. Frequently asked questions (FAQ) Can we determine TWRP No, on modern Xiaomi devices, it's impossible. The bootloader checks the digital signature of the Recovery image. TWRP It will be considered invalid, and the download will occur in stock mode. TWRP phone loads into MIUI? You probably didn’t follow the fastboot boot command. twrp.img For the first run or no change. MIUI When changes are detected in the bootloader, it automatically replaces it with its original when restarted. TWRP With customized recovery and unlocked bootloader, many banking apps and Google Pay may not work. What to do if TWRP asks for a password I don't remember (PIN-If you don't remember it or you've changed the locking pattern, the only way out is to run Format Data in the Wipe menu, which will delete all files from the phone. TWRP Installing software alone cannot physically break the hardware, but software errors can cause data loss or the need to flash through the service center if the device stops booting.
