Owners of Xiaomi, Redmi and POCO smartphones often face the need to gain direct access to system files or internal memory of the device, which may be required to remove undeleteable debris, restore the system after a failure or deep clean the partitions hidden from the average user. Understanding the structure of Android storage based on the shell MIUI or HyperOS allows you to solve many software problems without going to the service center.
There are several levels of memory access, from standard USB connection to the use of engineering menus and debugging by ADB. Each method has its own characteristics, risks and scope. In this article, we will discuss in detail how to securely log into your gadgetโs file system, what tools you will need to do this, and how to avoid critical errors that can turn your phone into a brick.
Before you start manipulating system partitions, it is important to be aware of the difference between user data and system files. Accidental deletion of critical elements at the root can lead to a loss of operation of the device. So before any actions with memory partitions, be sure to create a full backup of important data on an external medium or in the cloud. This is the only guarantee that experiments will not lead to irretrievable loss of information.
Connection via USB and file transfer mode
The easiest and safest way to log into Xiaomi memory is to use the standard USB interface. First, you need to connect your smartphone to your computer using a high-quality cable that can transfer data, not only charge the battery. After connecting, a notification will appear on the device screen about the USB mode, where the default mode is often chosen โOnly Chargeโ.
You need to switch this mode to File Transfer or MTP. This action will open access to user folders such as DCIM, Download and MIUI. However, it is worth noting that this method does not give full access to the system partitions where the logs, application cache and configuration files of the operating system are stored.
๐ก
Use the original Xiaomi cable or a certified USB 2.0/3.0-enabled counterpart, as cheap cables often cut data lines, leaving only charging.
If your computer can't see the device, check the drivers installed. Windows Device Manager may display an unknown device or device with an exclamation mark, which will require you to install official USB Drivers from the manufacturer's website or through the Mi PC Suite app (for older models) or Xiaomi ADB/Fastboot Tools.
- ๐ฑ Make sure the screen is unlocked when the cable is connected.
- ๐ป Check if the regime is in place MTP notice-curtain.
- ๐ Try it. USB-port on the computer, preferably USB 2.0.
- ๐ก๏ธ Disable the antivirus if it blocks new devices.
Using Recovery Mode to Access Files
Recovery Mode or Recovery is a separate mini-partition in the phoneโs memory that loads independently of the main operating system, and can be logged in by turning off the smartphone and holding the Volume Up + Power button combination before the Mi logo appears. Depending on the firmware version (Chinese or global), the menu may vary.
In stock Recovery, file system access is limited. Usually only "Wipe Data" and "Connect with MIAssistant" are available. It is the MIAssistant mode that allows you to connect to your phone via a computer using a special utility MiFlash or Mi PC Suite.
โ ๏ธ Warning: Do not use the "Wipe All Data" command in Recovery if your goal was simply to access files.This action will permanently delete all photos, contacts and applications from your device.
For advanced users, custom Recovery is possible, such as TWRP. This gives full access to the file system, allowing you to copy, delete and edit any files, including system files. However, installing TWRP requires unlocking the bootloader, which is officially only possible after waiting 168 hours (7 days) from the moment of the accountโs attachment.
โ๏ธ Checking before entering Recovery
Debugging by USB and ADB console
The most flexible memory tool is Android Debug Bridge (ADB), which requires pre-activation of the developer mode, go to Settings โ About phone and quickly click on the MIUI build number seven times. Once you have the message โYouโve become a developerโ, a new section will appear in the settings menu.
In the Developer menu, you need to find and enable the USB Debugging option. When you first connect to a computer, you will see a request for debugging permission from that computer on your smartphone screen โ you need to confirm it. Now you can send commands to the device via the Windows command line or the Linux/macOS terminal.
adb devices
adb pull /sdcard/DCIM/Camera/ C:/Backup/Photos
adb shell ls /data/local/tmpAdb pull allows you to copy a file from your phone's memory to your computer, and adb push allows you to upload a file from your computer to your phone. Using the adb shell command, you can go interactive and manage files like a Linux-like system using cd, ls, rm, cp commands.
Working with memory partitions through Fastboot
Fastboot mode is designed for low-level partition firmware and is often used to restore broken devices, and you can enter this mode by commanding adb reboot bootloader or by pressing the button Volume down + Power when the phone is turned off.
In this mode, the computer sees the device as Android Bootloader Interface. The main interaction takes place through fastboot console commands. This allows you to (view) device information, unlock the bootloader or reflash specific partitions such as boot, recovery, system, userdata.
| Fastboot Team | Description of action | Risk to data |
|---|---|---|
| fastboot devices | Checking the device connection | Safe. |
| fastboot reboot | Reboot as normal | Safe. |
| fastboot flash recovery img | Recording the image of Recovery | Medium (requires unlocking) |
| fastboot erase userdata | Complete cleaning of the user section | Critical (deletion of all data) |
Using Fastboot to write partitions requires extreme caution. Incorrectly selected firmware image for a particular model can lead to hardware conflict.Always check whether the firmware file matches the exact model of your smartphone (for example, the Redmi Note 10 Pro and Redmi Note 10 Pro Max have different firmware).
File Managers with root rights
For everyday memory management without a PC connection, file managers with Root rights support, such as MT Manager, Root Explorer or Solid Explorer, are the optimal solution. Obtaining superuser rights (Root) opens access to the root directory / where all system files are located.
Root rights typically involve unlocking the bootloader and installing a patched boot.img image through the Magisk utility. This allows applications to request permission to change system files. Once Root is activated in the file manager, you can see hidden folders, edit.conf and.xml configuration files, and delete system applications.
โ ๏ธ Warning: Changing system files through the Root Manager can disrupt system integrity and lead to a cyclic bootloop.Always backup before editing.
Special attention should be paid to /data/data, which stores data from all installed applications, access is only possible with superuser rights, you can find messenger cache, game databases and error logs, but simply cleaning the contents of this folder can lead to resetting of application settings or their failure.
What is a Data Section and Why is it Hidden?
Access to memory over the network (FTP/SMB)
Modern file managers, built into MIUI or installed additionally (for example, CX File Explorer, WiFi FTP Server), allow you to access the memory of the smartphone over a local Wi-Fi network. This eliminates the need to use cables and drivers.
To activate the function, you need to run an FTP or SMB server in the file manager application. The address will appear on the screen, for example, ftp://192.168.1.55:2121. This address must be entered in the address bar of the Explorer of Windows or any other file manager on a computer connected to the same Wi-Fi network.
This method is convenient for fast transfer of large amounts of data, since the speed is limited only by the performance of your router. However, it is worth remembering that access to system partitions via FTP is usually closed if the device does not receive Root rights.
- ๐ถ Make sure your phone and PC are on the same subnet.
- ๐ Some antiviruses can block incoming FTP-linkage.
- ๐ Power saving mode can turn off the Wi-Fi module, interrupting the connection.
- โก Transfer speed depends on the Wi-Fi standard (2.4 GHz or 5 GHz).
