Owners of Xiaomi Redmi 5 Plus (codenamed vince) often face the need to obtain advanced access rights to the system, which is required to install custom recavators, firmware modified versions of the OS or deep debugging applications. However, Windows 7, still popular on many PCs, does not have built-in universal drivers for modern Android devices, which creates a barrier for beginners.
Without properly established USB-The computer will not see the smartphone in debugging or Fastboot mode, as a result of any attempts to launch the device. ADB-In this article, we will discuss the process of searching, installing and validating drivers, focusing on the specifics of working with Windows 7, where manual installation is often the only correct solution.
The setup process may seem complicated only at first glance. If you follow the steps described below consistently, your Redmi 5 Plus will be successfully detected by the system in minutes.We will look at both automatic methods and manual installation through Device Manager, which is especially true for older versions of Windows.
Preparation of the workplace and smartphone
Before you start installing the software, you need to prepare the physical connection and software environment. USB-A cable that can transmit data, not just charge the device. Cheap “charging only” cables often cause the PC to fail to respond to the smartphone’s connection.
On the Xiaomi Redmi 5 Plus device itself, you need to activate the hidden developer menu. To do this, go to the settings, select About Phone and quickly click on MIUI Version seven times. After that, a new section will appear on the menu "Developers", where you need to include Debugging over USB and, if necessary, "Install via USB".
⚠️ Note: When you connect your smartphone to your PC in debugging mode, the device will request permission to debug from that computer. Be sure to click "Allow", otherwise the commands ADB will not be carried out.
It is also worth checking for updates for Windows 7 itself. The absence of Service Pack 1 (SP1) can lead to a problem with the digital signature of drivers, which will block their installation.
Download the necessary SDK components and drivers
To work with Android devices, a minimum set of tools is required, known as Platform Tools, which is the official utility from Google, which contains executable files adb.exe and fastboot.exe. You should download them exclusively from official sources to avoid the introduction of malicious code into the system.
In addition to platform tools, Windows 7 often requires a separate installation of the universal driver Google USB Driver or a specialized driver from Xiaomi. Unlike newer versions of Windows, the “seven” does not know how to automatically pull these components from the Internet when you first connect the device.
- 📥 Download the Android archive SDK Platform-Tools from the official developer website.
- 💾 Download the universal Google driver USB Driver or use the driver built into the Mi Unlock Tool.
- 📂 Unpack downloaded archives in the root of disk C: for ease of working with the paths, for example, in a folder C:\adb.
It is important to understand the difference between the modes of connection. For normal debugging, you need ADB mode, and for flashing, you need Fastboot mode. Drivers for these modes can be installed separately, so it is recommended to have both sets of files on hand in case the automatic installation goes wrong.
Manual installation of drivers through Device Manager
The most reliable way to get Windows 7 to see Redmi 5 Plus is by manually installing it through Device Manager. Auto Search often doesn't find the right files in the local folder, so we'll be pointing the way forcibly. Connect your smartphone in debugging mode to your computer.
Open Device Manager (press Win + R and type devmgmt.msc). In the list of devices, you will see an unknown device with a yellow exclamation mark, usually under "Other Devices" or "Portifical Devices." Right-click on it and select "Update Drivers."
☑️ Verification of driver installation
In the window that opens, select “Search for drivers on this computer” and then “Select a driver from the list of drivers already installed.” Click “Install from disk” and through the “Overview” button, specify the path to the folder where you previously unpacked the drivers (for example, C:\adb The system has to find the file. android_winusb.inf.
After selecting a device model (usually Android ADB Interface or Bootloader) confirm installation. Windows 7 may issue a warning about the digital signature of the driver - in which case you must agree and continue installing anyway.
Set up environment variables to run ADB
Once the drivers are successfully installed, you need to configure the system to recognize ADB commands from any folder, not just from the directory where the executable is located, and this eliminates the need to enter the full path to the command every time.
Right-click on "Computer", select "Properties", then "Additional System settings". In the window that opens, click "Environmental Variables". In the "System Variables" block, find the Path line and select "Change".
⚠️ Attention: When editing the Path variable, be extremely careful. Don't delete existing values, otherwise some system programs may stop working. Add a new path to the end of the line by putting a semicolon in front of it.
At the end of the line, add a path to a tool folder, such as:;C:\adb. After saving the changes, you need to restart the computer or at least reopen the command line to make the changes effective.
What to do if the Path is not saved?
Connection check and diagnosis of problems
The final step is to check the health of the PC-smartphone bundle. Open the command line (cmd) and type in the adb device command. If done correctly, you will see a list of connected devices with the serial number and device status.
If you see "unauthorized" instead of "device" status, look at your smartphone screen. There should be a request for debugging confirmation. If the screen is black or the request doesn't appear, try reconnecting the cable or rebooting the phone. The "offline" status usually indicates problems with the driver or ADB version.
| Status at ADB | Meaning | Action |
|---|---|---|
| device | The device is connected and ready to go. | You can run commands. |
| unauthorized | Requires confirmation on the phone screen | Unlock the screen and press "Allow". |
| offline | Communication failure or incorrect driver | Reconnect the cable, check the driver |
| (empty) | No device found. | Check cable, USB mode, drivers |
To check for Fastboot mode, enter the adb reboot bootloader command. The smartphone will reboot to bootloader mode. In the command line, enter fastboot devices. The appearance of the serial number confirms that the Fastboot driver is also installed correctly and the Redmi 5 Plus is ready for firmware.
Frequent errors when installing on Windows 7
One of the most common problems is the driver digital signature error. Windows 7 strictly monitors the integrity of system files. If the driver is not signed by Microsoft or the signature is expired, the system blocks its installation, in which case it may be necessary to temporarily disable signature verification when the OS boots.
Users often confuse USB connection modes. In the smartphone notification menu, when connecting the cable, you need to select File Transfer (MTP) or PTP mode. Charge only mode will not allow the computer to see the debugging interface, even if the drivers are installed perfectly.
- 🔌 Port problem: Try connecting the cable to another USB-connector, preferably directly into the motherboard (behind the PC), bypassing the front ports and hubs.
- 🛡️ Antivirus: some antiviruses block drivers from entering the system. Try temporarily disabling protection.
- 📱 Screen locking: ADB does not work if the smartphone screen is locked with a password.Unlock the device before entering commands.
If nothing helps, it makes sense to completely remove previously installed drivers through Device Manager (select device -> Remove by ticking the “Delete Driver Programs” box and start the process again using another USB-cable.
💡
Use the adb kill-server and adb start-server command in the command line to restart the ADB demon. This often helps if the device suddenly stops responding after a long run.
💡
The main difficulty of installation on Windows 7 is the lack of automatic search for drivers on the Internet, so manually specifying the path to files through Device Manager is a must.
