Installation of Russian firmware on the router Xiaomi Mi Router 4A

Owners of popular routers from the Chinese corporation often face a pleasant price, but an unpleasant limitation - the lack of Russian in the management interface. Standard Chinese firmware Xiaomi Mi Router 4A does not allow you to fully configure the device without knowing the characters or using a translator in the browser, this creates a barrier to set up security, port port port port port and management of the guest network.

The solution is to completely replace the router’s operating system with custom builds like Padavan or OpenWrt. These systems are free of language restrictions, run more stable than stock ones, and open access to advanced features like installing VPNs, torrent clients, and ad blockers. The process of replacing software requires care, but the result is worth it: you get a fully Russified and powerful network center.

Before you start, you need to clearly understand the difference between a simple update and flashing. If the update via the menu saves all settings, installing third-party software completely erases the current configuration of the device, your task is to prepare all the necessary files in advance to minimize network downtime and avoid errors in the boot process.

Preparation of equipment and choice of firmware

The first step is to determine the exact hardware version of your router. Xiaomi Mi Router 4A comes in two main versions: Gigabit Edition and regular (100 Mbps). Visually they are almost identical, but have different processors and memory, so firmware from one version is not suitable for another and can turn the device into a “brick”.

If you look at the sticker at the bottom of the case. If it says "Gigabit" or 1000 Mbps port speed, you need files marked AC2100 or Gigabit. For the normal version, look for files labeled 100M or R4A. You should only download software from trusted resources, such as the 4PDA forum or the official Padavan project repository, to avoid malicious code.

⚠️ Warning: Do not try to fill the firmware from the Gigabit version on a regular router and vice versa.This will lead to irreversible damage to the bootloader, and the device can only be restored using a soldering iron and a programmer. SPI.

You will also need a computer with a network port (or a USB-LAN adapter) and a short Ethernet cable to work. Wi-Fi connection for the firmware process is strongly discouraged, as any signal jump can interrupt data transmission and violate the integrity of the file system.

💡

Use a cable no longer than 1-1.5 meters long to connect to your computer. Low-quality long cables can cause interference that is not critical to the Internet, but fatal when you run firmware.

Required tools and files

Successful software replacements require a dedicated set of utilities, the main tool for working with Xiaomi routers is the Xiaomi Router Tool or its console counterpart for Linux/Mac. These programs allow you to send a special signal to a device that allows you to install modified software.

You will also need a firmware file in.bin format. The most popular and stable for this model is the build of Padavan from the author of HANFENG. It is characterized by low resource consumption and the presence of Russian language out of the box. The file usually weighs about 6-8 megabytes.

The table below shows the main differences between the router versions so you can finally make sure that the file is right:

Make sure your computer has turned off antivirus firewalls that can block network requests from the firmware utility. Sometimes the built-in Windows protector perceives the program’s network activity as a threat and interrupts the connection to the router at the most inopportune moment.

Unlocking the bootloader and entering the firmware mode

Official Xiaomi routers have a locked bootloader that prohibits installation of software with a digital signature other than factory. To circumvent this limitation, use the Telnet exploit method or a special script. The 4A Gigabit model often requires pre-installing the Chinese version of the firmware if you have a global one.

The unlocking process begins with the router connecting to the PC with a cable to the LAN1 port. Launch the unlock utility and press the start button. At this point, you will physically press and hold the Reset button on the router body for a few seconds until the system indicator starts flashing yellow.

If done correctly, the utility will report successful unlocking and the router will restart. Now, the web interface at 192.168.31.1 (or miwifi.com) should be able to download the file through the standard update menu, or the device will go into recovery mode.

⚠️ Warning: Do not turn off the router power during the flashing of the indicator. Interrupting the bootloader recording process at this stage is guaranteed to disable the device without the possibility of software recovery.

The process of installing custom firmware Padavan

Once successfully unlocked, proceed to the new operating system installation directly. Open your browser and go to the router control panel. Find the System Status or Manual Update section (the button is often hidden in the submenu or is available via a special link if you use the web version of the utility).

Select the previously downloaded firmware file.bin. The system will warn you that all settings will be reset. Confirm the action and wait for the process to be completed. The router will overwrite the memory partitions, install a new bootloader and file system. This takes 2 to 5 minutes.

Unlike the stock system, the new firmware can prompt you to choose the interface language immediately. If this does not happen, by default, after the first download, Padavan often activates English or Russian depending on the regional time settings or build version.

After the first download, it is recommended to perform a full reset (“Hard Reset”), even if the system offers to save the configuration, which ensures that the old Chinese settings do not conflict with new scripts and modules of Russian firmware.

Primary configuration and Russification of the interface

After rebooting, connect to a new Wi-Fi network, usually called “Padavan” or “ASUS”, or connect the cable to the LAN port. In the address bar, type 192.168.1.1. You will see an interface that may already be in Russian. If English is displayed, go to Administration → System and select Russian in the Language drop-down list.

The system will offer to configure the type of Internet connection. For most providers in the CIS, the type "Automatic" is suitable. IP» (DHCP). If your provider uses PPPoE (login and password required), select the appropriate item and enter the data from the contract. MAC-address, if the provider links the Internet to the device – in the new firmware there is a cloning function MAC-address.

In the "Advanced" section, you have powerful tools that you didn't have in the drain. You can set up a speed limit guest network, run it. VPN-client to bypass locks or configure a torrent rocking board if connected to the router USB-The drive (relevant to the Gigabit version).

💡

The main feature of Padavan firmware is modularity: you can only turn on the functions you need (VPN, torrents, DNS), without loading the processor with unnecessary services, which ensures high stability.

Don’t forget to change your administrator password and Wi-Fi key right away. Custom firmware often has simple combinations or an open network in its default, making your router vulnerable to neighbors in the first minutes of operation.

Typical Problems and FAQs

Users may encounter various difficulties in the process of flashing, and the problem is often in the browser: the cached data of the old admin page can interfere with the correct operation of the new one, in which case cleaning the cache or logging in through Incognito mode helps.

Another common situation is that the router does not see the provider's cable. In the new firmware, the order of the ports may differ from the stock one. Try switching the cable from the WAN to LAN1 or vice versa, or check the settings in the Internet section by selecting the right port for the WAN.

If you forget the password from the new admin, the physical reset button will help. 10 The power is on until the lights blink, which will return the settings to the factory Padavan firmware values (login/password usually). admin/admin).
