How to install Chinese firmware on the Xiaomi router AX3600: full-length guide

Xiaomi router AX3600 — One of the most popular dual-band routers with Wi-Fi support 6, But its global firmware often limits functionality: there are no QoS settings, no support IPv6 In full, and the interface-world The installation of the original firmware from Xiaomi China allows you to unlock hidden features, but the process is fraught with risks from loss of warranty to “filling” the device.

In this guide, we will discuss three official ways to install Chinese firmware (via the web interface, SSH We will analyze the differences between the firmware versions, and also give a checklist to check the device before the procedure, paying special attention to typical errors - for example, why the router can freeze during the boot phase or why 5 GHz access is lost after the firmware is lost.

Why you should (or should not) install Chinese firmware

The main advantage of Chinese firmware is the advanced functionality, for example, it provides:

• 🔧 Full support IPv6 (In the global version, it often only works in the "DS-Lite" mode")
• 📊 Advanced QoS settings with prioritizing traffic by application
• 🌐 More regions to select Wi-Fi frequencies (including channels) 12-14 into 2.4 GHz)
• 🔄 Automatic backup of settings in the cloud Xiaomi

But there are also serious disadvantages:

• ⚠️ Loss of warranty – Xiaomi doesn’t officially support manual firmware change.
• 📵 No Russian language in the interface (Chinese and English only).
• 🔌 Compatibility issues with some features (e.g. Mi Home may not see the router).

⚠️ Attention: If yours AX3600 When purchased in Russia or Europe, Chinese firmware may violate local standards (e.g., 5GHz transmission power limits) and may cause problems with connection of some devices.

Before proceeding, check the current firmware version in the web interface (192.168.31.1) in the Status section. → If you already have a Chinese version (the title will be the same) CN), Updating through the standard method can block the router!

Router Preparation: Checklist before firmware

Incorrect preparation is the main reason for “bricking" AX3600. Follow this checklist to minimize risks:

Download the correct firmware version (see table below)

Backup your current settings in the System → Backup & Restore

Connect the router to the PC via cable (Wi-Fi may shut down during the process)

Disconnect all devices from the router except the computer

The router should be charged ≥50% (or plug in the power supply)

-->

Pay special attention to firmware selection, here are the current versions for early 2026:

Critical: Firmware files for AX3600 and AX3600 EE (European version) incompatible! Make sure you download the firmware for your model (see the sticker on the bottom of the router).

Also prepare:

• 🖥️ Windows computer 10/11 or Linux (for the SSH-method)
• 🔌 Ethernet cable (Wi-Fi will shut down during firmware)
• ⚡ Uninterruptible power supply (if there are voltage surges in your region)

💡

If you have a Mac, use the terminal. iTerm2 Instead of the standard, it works better with Chinese characters. SSH.

Method 1: Installation via web interface (the easiest)

This method is suitable if you already have Chinese firmware of the old version or global firmware with the possibility of manual updates. It does not work on routers with a blocked bootloader (for example, purchased from official distributors in the EU).

Step-by-step:

1. Download the firmware (file with.bin extension) and rename it to miwifi.bin.
2. Connect to the router via cable and go to the web interface at 192.168.31.1.
3. Go to System. → Manual Upgrade.
4. Download the file. miwifi.bin and wait for the process to be completed (~5 minute).
5. After the reboot, the router will be available for the same IP, but with a Chinese interface.

⚠️ Note: If the router stops responding to ping after downloading the file (>10 - Don't try to reset it. 20-30 Minutes – sometimes the process takes longer due to checking the firmware signature.

If the web interface is experiencing an error called “Invalid file”, it means:

• 🔹 You downloaded the firmware for another model (check the file name).
• 🔹 Your router has a blocked boot loader (need a method through the SSH).
• 🔹 File corrupted (download it and check check the checksum) MD5).

💡

The web interface is the most secure method, but only works if the router is already unlocked for manual updates.

Method 2: Firmware through SSH (power-user)

If the web interface refuses to accept firmware, you can download it through SSH. This method requires access to the Telnet/SSH, It's the default one that's disabled in the global firmware:

1. Install PuTTY (Windows) or use the built-in terminal (Linux/Mac).
2. Connect to the router via Telnet (port 23) with the root login and password from the sticker on the router.
3. Run the command to unlock. SSH: nvram set ssh_en=1 nvram set uart_en=1 nvram commit reboot
4. After restarting, connect to SSH (port).

Then download the firmware to the router:

1. Download the firmware to your computer and rename it to firmware.bin.
2. Use it. SCP To transfer the file to the router: scp firmware.bin root@192.168.31.1:/tmp
3. Connect to the SSH and do: cd /tmp mtd write firmware.bin firmware
4. Wait until the router is finished (the router will restart automatically).

If SSH refuses to connect, check it out:

• 🔌 Correctness IP-address (by default 192.168.31.1).
• 🔑 Password (it is indicated on the sticker under the router, if not changed).
• 🔒 firewall Windows/Linux (It can block the connection).

Method 3: Firmware through recovery mode (if the router is not turned on)

If the router is stuck after a failed firmware or does not respond to other methods, you can use the recovery mode (U-Boot).

1. Turn off the router.
2. Press the Reset button (on the back) and plug in the power.
3. Hold the button. 10-15 seconds until the indicator starts to flash orange quickly.
4. Release the button and the router will go into recovery mode.

Next:

1. Set up on PC static IP 192.168.1.2/24.
2. Open your browser and go to 192.168.1.1.
3. Download the firmware through the recovery web interface.
4. Wait until the process is completed (the process will take place) ~10 minutes).

⚠️ Note: If the router is not determined by IP 192.168.1.1, Try to connect through TFTP. To do this, in the Windows command line, run: tftp -i 192.168.1.1 PUT firmware.bin (file firmware.bin It should be in the same folder where the team is launched).

If the router does not leave the recovery mode (>20 minutes, that could mean:

• 🔹 The loader is damaged (requires firmware through the UART).
• 🔹 Inappropriate firmware version (check the router model again).
• 🔹 Power problems (try another power supply).

Solving typical problems after firmware

Even if the firmware is successful, there may be problems, and here are the most common ways to fix them:

If after firmware router began to behave unstable (self-reboots, loss of connection), perform reset to factory settings:

1. Press the Reset button for 10 seconds.
2. Wait for the reboot (the indicator should burn blue).
3. Configure the router again through the web interface.

💡

If the router does not reset IP down DHCP, hand-appoint IP 192.168.31.X (255.255.255.0 mask and try to go to 192.168.31.1.

How to return global firmware if Chinese is not suitable

If Chinese firmware caused problems (for example, unstable work with certain devices), you can return the global version.

1. Download the global firmware (see the table in the section "Preparation").
2. Rename the file to miwifi.bin.
3. Download it via the web interface (System) → Manual Upgrade).
4. If the web interface refuses to accept the file, use the method through SSH or remediation.

Important: if you roll back on global firmware, all settings will reset. Export the configuration to System in advance → Backup & Restore (although it is not always possible to restore it after a firmware change).

⚠️ Warning: Some routers may lose access to 5GHz after a rollback to global firmware, due to regional restrictions, and the solution is to manually install China in Wi-Fi settings, even if you have global firmware.
