In this article - 5 Proven Ways to Update Xiaomi Without Wi-Fi, including methods through mobile Internet, PC, local network and even someone else's routerWe will analyze the nuances for different models (from Redmi Note 10 to Xiaomi 14), we'll warn you of the risks and show you how to bypass system restrictions. Important: Some methods require technical expertise—if you're a beginner, start with the simplest options.

Spoiler: the most reliable way is update via PC using the official utility Mi Flash ToolBut if you don't have a computer handy, alternative solutions will do. Below are detailed instructions with images (for key steps), a compatibility chart, and answers to frequently asked questions.

1. Update via mobile Internet (bypass restrictions)

By default Xiaomi blocks the loading of firmware files weighing more than 20–50 MB via a mobile network. But this limitation can be bypassed in two ways: via developer mode or VPN.

Method 1: Disabling the limit through developer settings

1. Open Settings → About phone and press 7 times MIUI versionto activate developer mode.
2. Return to Settings → Advanced → For developers.
3. Find the option Limit background traffic and turn it off.
4. Restart your phone and try updating through Settings → System Update.

Method 2: Using a VPN

Some users report that when connecting to a VPN (for example, ProtonVPN or Warp by Cloudflare) the system stops blocking downloads. Why does this work? Xiaomi determines the network type by IP address, and a VPN can "trick" the system into thinking you are connected to Wi-Fi.

• 🔄 Pros: Does not require a PC, works on most models.
• ⚠️ Cons: high traffic consumption (firmware can weigh 1.5–3 GB), failures are possible due to unstable connection.
• 📱 Suitable for: Redmi 9/10/11, POCO X3/X4, Mi 11/12.

⚠️ Attention: If the update is interrupted during the installation stage (for example, due to a connection failure), the phone may get stuck on the logo MIIn this case, you will need Forced reset via Fastboot.

2. Update via PC (Mi Flash Tool)

This is the most reliable method if you have a computer with WindowsYou will need:

• Cable USB-TypeC (original, no damage).
• Official utility Mi Flash Tool (download from en.miui.com).
• Firmware in format .tgz or .zip for your model.

Step-by-step instructions:

1. Download the firmware for your model from the website en.miui.com/download.html (choose version Stable, if you are not sure).
2. Unzip the archive into a folder without Cyrillic characters (for example, C:\MIUI\).
3. Install Mi Flash Tool and drivers Qualcomm (if the phone has a processor Snapdragon).
4. Turn off your phone, hold down Volume Down + Powerto enter the mode Fastboot.
5. Connect your phone to your PC, Mi Flash Tool select the folder with the firmware and click Refresh → Flash.

The process will take 5–15 minutesOnce completed, the phone will automatically reboot.

⚠️ Attention: If after flashing through Mi Flash Tool The phone does not turn on, check:

• Correctness of the selected firmware (for Redmi Note 11 The firmware from won't fit Redmi Note 11 Pro).
• Cable integrity (try another one) USB ports on PC).
• Availability of drivers (in Device Manager there should be no exclamation marks next to Android Device).

3. Update via local network (Hotspot)

If you have a second phone, tablet or laptop with Wi-Fi, you can share the Internet over a local network. This method is suitable if:

• Do you have unlimited tariff on the main device.
• Several phones need to be updated Xiaomi simultaneously.
• The Wi-Fi router is unstable, but the mobile Internet is stable.

How to set up:

1. On the main device (eg. iPhone or Samsung) turn on Tethering → Wi-Fi Hotspot.
2. On Xiaomi connect to this access point.
3. Run the update via Settings → System Update.

Nuances:

• 🔋 Power consumption: Wi-Fi sharing drains the battery significantly. Connect the main device to a charger.
• 📶 Speed: if mobile internet is slow (<5 Mbps), the firmware download may be interrupted.
• 🔒 Safety: Set a complex password on your access point to prevent unauthorized devices from connecting.

What to do if the phone does not see the access point?

Check if the mode is enabled 2.4 GHz on the dispensing device (some models Xiaomi do not support 5 GHz in Hotspot mode).

Disable VPN or proxy on both devices.

Restart both gadgets and try again.

4. Update via someone else's Wi-Fi (cafe, hotel, friends)

If you don't have your own Wi-Fi but have access to other people's networks (at a cafe, library, or friends), you can use them. However, there are risks:

• 🚫 Port blocking: Some public networks limit the download of large files.
• 🕵️ Data interception: Man-in-the-middle attacks are possible in open networks.
• ⏳ Time limit: In hotels, Wi-Fi may be disconnected after 1–2 hours no activity.

How to minimize risks:

1. Use VPN (For example, Windscribe or NordVPN) to encrypt traffic.
2. Check your network speed via Speedtest - If <10 Mbps, the update may take hours.
3. Disable automatic installation of updates in Settings → System update → ⚙️ → Auto-update.

Critical information: On networks with portal authentication (where you need to enter your login/password in the browser), the update may not start. In this case, try connecting via Developer Mode → Network → Set Proxy Manually (specifying the IP and network port).

5. Update via Recovery (for advanced users)

If all the previous methods did not work, you can install the firmware manually through Recovery modeThis method requires:

• Knowledge of working with ADB And Fastboot.
• Backup your data (all files will be deleted!).
• Firmware in format .zip for your model.

Instructions:

1. Download firmware for Recovery from the website en.miui.com (look for files marked Recovery ROM).
2. Rename the file to update.zip and place it in the root of your phone's internal memory.
3. Turn off your phone, hold down Volume up + Powerto enter Recovery.
4. Select Install update.zip and confirm the installation.

Warnings:

• ⚠️ Do not interrupt the process - this will lead to "briku" (non-operability) of the phone.
• ⚠️ On some models (Xiaomi 12S Ultra, Redmi K50) requires preliminary unlocking of the bootloader.
• ⚠️ After installation, the phone will perform factory reset.

6. Alternative methods (for specific cases)

If none of the methods work, consider these options:

Method 1: Update via operator SIM card

Some operators (eg. MTS or Tele2) offer an "Over-the-Air Software Update" service via your SIM card. Check with your carrier—sometimes it's free.

Method 2: Contacting a service center

If the phone is under warranty, go to official service centers Xiaomi can update the firmware for free. List of centers: mi.com/ru/service/location/.

Method 3: Using third-party utilities

Programs like XiaomiTool V2 or MiFlashPro Allow you to flash your phone without official restrictions. However, this is risky:

• 🔴 Warranty may be voided.
• 🔴 Risk of installing unofficial (custom) firmware with bugs.
• 🔴 License required root (they are difficult to obtain on newer models).

⚠️ Attention: Service center interfaces and operator terms and conditions are subject to change. Before visiting, check their official websites for current rules.
