How to install a downloaded firmware on Xiaomi through the “three dots”: a safe way without Fastboot

Firmware on a Xiaomi smartphone via a hidden three-dot menu (or System Update with a file selection) is one of the safest ways to update software without using Fastboot or recovery. This method is suitable for devices with an unlocked bootloader and official / custom firmware in.zip format. The main advantage is the absence of the risk of “bricking” when you perform the steps correctly.

Many users are afraid to stitch through smartphones for fear of losing data or damaging the system, but the “three-point” method (aka Choose update package) is minimally traumatic: it does not require resetting and even works on devices with a locked bootloader (if the firmware is signed by Xiaomi), it is important to choose the right version of the software for your model, otherwise the system will refuse to install it.

In this article, we’ll break through the process from preparation to final reboot, point out common mistakes, and give you tips on how to avoid problems. If you’ve never flashed Xiaomi before, this is the perfect start.

What is “Firmware through three points” and who it is suitable for

The three-dot menu is the informal name for a hidden option in the standard System Update app on Xiaomi smartphones. It allows you to manually select a firmware file.zip from internal memory or SD-maps and install them without using a PC. The method works on most of the brand's devices, including:

• 📱 Redmi Note series: Note 10/11/12, Note 10 Pro, Note 11 Pro+ etc.

The method is suitable for:

• ✅ Updates to the new version MIUI (for example, 13 to 14).
• ✅ Downgrade (rollback) to the old firmware if the new one is unstable.
• ✅ Install custom firmware (e.g. Xiaomi.eu or PixelExperience) if they support this method.
• ✅ System recovery after a failure (if the smartphone is turned on, but does not work correctly).

Important: The method will not help if:

• 🚫 The device does not turn on or is stuck on the Mi logo (needs a Fastboot or a Fastboot). EDL).
• 🚫 The bootloader is locked, and the firmware is unofficial (unlocking is required).
• 🚫 The firmware file is corrupted or intended for another model.

Preparation of the smartphone: 5 mandatory steps before firmware

Even a method as secure as three-point installation requires preparation, and neglecting these steps can lead to endless downloads, data loss, or failure to install firmware.

Let's take a closer look at each item:

1. Selection of firmware. The file must correspond to:

• 📌 Smartphone models (for example, redmi_note11_pro_global For the Redmi Note 11 Pro).
• 📌 Region: global (international), eea (Europe), ru (Russia), cn (China).
• 📌 Type: stable (stable) or weekly (weekly).

Download the firmware only from official sources:

• 🔗 Official website MIUI (for global versions).
• 🔗 Xiaomi.eu (for custom firmware with support for Russian language).
• 🔗 XDA Developers (for enthusiasts).

2. File check. After download:

• 🔍 Compare the hash sum (MD5/SHA1) file on the site (use utilities like HashMyFiles).
• 📁 Rename the file to a short name without spaces (e.g, miui14.zip).
• 📲 Move it to the root folder of internal memory (not nested folders!).

3. Battery charge. The minimum threshold is 50%, but it is better to charge up to 80%. If the smartphone runs out during firmware, this can damage the system files.

4. Backup: Three-dot firmware usually doesn't erase data, but 5% of the time, you may reset due to version conflict.

• 📸 Photo/video (in the cloud or on PC).
• 📱 Contacts (export to.vcf).
• 🔑 Passwords and application data (use Mi Cloud or Google Drive).

5. Disable lock. After firmware may require input PIN-It's a code or a pattern lock, but sometimes the system doesn't recognize it:

• 🔓 Remove all ways to block in Settings → Lock screen → Type of lockdown.
• 🔄 Put the debugging on. USB (if you plan to use it ADB kickback).

💡

If you are flashing a smartphone with an unlocked bootloader, check before installing whether the new firmware supports your unlock type. Some custom builds require re-unlocking after the upgrade.

• 🔍 If the file is not, check if it is hidden (enable the display of hidden files in the Explorer settings).
• ✅ Put the file on it and confirm the choice.

Step 3. Start checking the file.

• ⏳ The system will start checking the firmware integrity (may take 1-3 minutes).
• ❌ If you have a Can't verify update, you will be able to:

Step 4. Confirm installation.

• ⚠️ A warning will appear about possible data loss (even if the risk is minimal).
• ✅ Click Reboot and install or Update (depending on version) MIUI).
