Return to the factory firmware Xiaomi: 3 proven ways (with unlocking the bootloader)

Returning a Xiaomi, Redmi or Poco smartphone to the factory firmware can be necessary in a variety of situations: after a failed update, when selling a device, to eliminate software failures or just for a clean start. However, the process of rolling back to stock MIUI is not always easy – especially if the device previously installed custom firmware, unlocked the bootloader or changed the regional version of the software.

The main difficulty is that Xiaomi uses a secure bootloader, as well as attaches firmware to specific regions and models. Wrong actions can lead to a device “brick” (completely inoperable) or loss of IMEI or locking the Mi Account. In this article, we will discuss three officially supported ways to return to factory firmware, including the nuances of working with Flash Mi Tool, Fastboot and Recovery tools, and explain how to avoid typical errors.

1.Preparation for rollback: what to do before firmware

Before you start returning the firmware, you need to follow a few critical steps, and neglecting them can lead to data loss, locking the device or even failure.

First, back up all the data. Even if you plan to flash your device through Recovery while saving user files, there's always a risk of failure. Use Mi Cloud, Google Drive, or local copying to your PC to save:

• 📱 Contacts (exports to VCF)
• 📸 Photos and videos (folders) DCIM and Pictures)
• 📄 Documents and downloads
• 🔑 Logins and passwords (unless you use a password manager)

Second, check the current MIUI and device model. You can do this from the Settings menu → About the phone.

• 📱 The exact name of the model (for example, Redmi Note 11 Pro) 5G, Not just a note 11")
• 🔢 Version MIUI (for example, MIUI Global 14.0.5)
• 📅 Firmware assembly date

This data is needed to select the correct firmware file on the official Xiaomi website. Error in choosing the region (Global/EU/China) or version (Stable/Developer) can lead to network problems or lock the device.

⚠️ Note: If your device has previously installed custom firmware (such as LineageOS or Pixel Experience) before returning to stock MIUI You must unlock the bootloader through the official Mi Unlock Tool. Otherwise, the firmware will end with an anti-rollback error or the device will stop turning on.

2. Method 1: Recovery (without PC)

The easiest way to return to the factory firmware is to use the built-in Recovery Mode, which is suitable for devices that have not changed the bootloader or installed custom recovery (for example, TWRP), the main advantage of this method is that there is no need for a computer and minimal risk of “brick”.

To start, download the official firmware for your model from MIUI Downloads. Choose a file marked Recovery ROM (usually with the.zip extension).

• 🌍 Region (Global, EU, China, India, etc. – should be the same as the current
• 📱 Exact model (e.g. Redmi Note 10 Pro and Redmi Note 10 Pro Max) - different devices!)
• 🔄 Type of firmware (Stable or Developer)

Next, follow the following steps:

1. Rename the downloaded firmware file to update.zip and move it to the root directory of the device’s internal memory (not folders!).
2. Turn off your smartphone.
3. Press the button combination to enter Recovery: For most models: Power + Volume up For some older devices: Power + Volume up + Volume down

Install update.zip to System

Confirm the installation and wait until the process is completed (usually takes 5-10 minutes).

After restarting, the device will be reset to factory settings.

Download the correct version of Recovery ROM|Rename the file to update.zip|Put the file in the root of the memory|Charge your phone at least to 50%|Know the key combination to enter Recovery-->

This method is suitable for most situations where you want to return the device to its original state without using a PC, but it has limitations:

• ❌ It does not work if custom recovery is installed (TWRP)
• ❌ It does not allow you to run an older version. MIUI (Anti-rollback protection)
• ❌ It will not work if the loader is blocked after installing custom firmware

3. Method 2: Fastboot Firmware (from PC)

If the Recovery method is not suitable (for example, due to a modified bootloader or installation errors), you can use the firmware via Fastboot mode. This method requires a computer with Xiaomi drivers installed and the official Mi Flash Tool utility.

First of all, unlock the bootloader (if it is blocked).

1. Link your Mi Account to your device in settings (Settings → Xiaomi Account).
2. Activate USB debugging and OEM unlocking in the developer menu (Settings → About Phone → MIUI version – press 7 times, then go back to Additional → For Developers).
3. Download Mi Unlock Tool from the official website and follow the instructions for unlocking.

After unlocking the loader:

1. Download Fastboot ROM for your model (file with.tgz or.zip extension).
2. Unpack the archive in a folder on your computer (the way without Cyrillic!).
3. Install Xiaomi drivers (you can use the Mi Flash Tool).
4. Turn your phone into Fastboot mode: (a) Turn off the device b) Press Power + Volume down until the screensaver with a rabbit in its cap appears
5. Connect your phone to your PC and start the Mi Flash Tool.
6. In the utility, select a folder with the unpacked firmware, then press Refresh (the device should appear).
7. Select firmware mode: Clean all – full reset (recommended) Clean all and lock – reset + lock bootloader (only for sale) Save user data – data retention (not always working)

Flash

💡

If the Mi Flash Tool gives you a can't find fastboot error, try running it on behalf of the administrator or install the drivers manually through Device Manager (select "ADB Interface" for the device in Fastboot mode).

⚠️ Note: If you are flashing a device with a locked bootloader (for example, after buying from a root), the Mi Flash Tool will not be able to complete the process. In this case, first unlock the bootloader through the Mi Unlock Tool, even if it was previously unlocked - the binding to the account could fly off.

Method 3: Using EDL Mode (for "bricked" devices)

If Xiaomi’s smartphone doesn’t turn on at all (black screen, logo hover, bootloop), it may be necessary to run the firmware through EDL (Emergency Download Mode) mode, a method used in service centers and requires special equipment or a Xiaomi author account.

Mi Flash Pro (an unofficial version of the Mi Flash Tool with EDL support) is suitable for home use, but keep in mind:

• 🔓 Authorized Mi Account required (you can buy or find it publicly, but this violates Xiaomi’s rules).
• 🔌 Qualcomm 9008 drivers (manually installed).
• 💻 The process is more complicated than in Fastboot, and there is a risk of finally "kill" the device if errors occur.

Step-by-step instructions for EDL:

1. Download the firmware in format EDL (This is usually a file with an.mbn extension or an archive with a folder. prog_emmc_firehose).
2. Install the Qualcomm HS-USB QDLoader 9008 driver (can be found on the 4PDA or XDA forums).
3. Transfer the device to EDL mode: For working devices: through the command adb reboot edl. For "dead" devices: close the test points on the motherboard (requires disassembly).

This is the last chance to bring the device back to life if other methods have not worked, but it requires technical skills and is not recommended for beginners. If you are not confident in your abilities, you should contact a service center.

5. Common Mistakes and How to Avoid Them

Even when following instructions, users often have trouble returning to factory firmware, and let's look at some of the most common mistakes and ways to fix them.

Error 1: Incompatible version of the firmware

Symptoms: Firmware via Recovery or Fastboot ends with an anti-rollback error or the device is stuck on the logo.

The reason: Xiaomi uses an anti-rollback mechanism that prevents rollbacks to older versions of MIUI. For example, if the device was on MIUI 14 and you are trying to flash MIUI 13, the process will fail.

Solution: Always use the firmware of the same or newer version. Check the current version in the settings or on the Xiaomi website.

Mistake 2: Blocking your Mi Account

Symptoms: After firmware is installed, the device requires login and password from the previous Mi Account, even if you have performed a reset.

Reason: On devices with an unlocked bootloader, Xiaomi ties the device to an account. After flashing through Fastboot with the Clean all and lock option, authorization may be required.

Decision:

• If you know your account details, enter them.
• If your account is not yours (the device is hand-built), contact the previous owner or support Xiaomi with proof of purchase.
• In extreme cases, you can try to flash the device through EDL with complete data erasure (but this does not always work).

Mistake 3: Loss of IMEI or network

Symptoms: After the firmware disappears mobile network, in the settings does not display IMEI or the inscription Invalid IMEI appears.

Reason: When you run through Fastboot with the Clean all option, the data of the modem module responsible for communication can be erased.

Decision:

1. Check the IMEI in the Engineering Menu (*#06#).
2. If IMEI No, no, restore it through QCN-file (requires root or access to the file) EDL).
3. Reflash the device using the file non-HLOS.bin (included in the firmware).

💡

Always check firmware compatibility with your model and region. Installing firmware for the Redmi Note 10 Pro (Global) on the Redmi Note 10 Pro (India) can result in network loss or device lock.

6. How to check the success of the rollback to the factory firmware

Once the firmware is complete, you need to make sure that the device is back to its original state.

1. Verification of the MIUI version

Go to Settings → About the phone and compare the version of MIUI with the one you were trying to flash. It should match completely (for example, MIUI Global 14.0.5.0.SKFMIXM).

Status of loader

If you have blocked the bootloader (Clean all and lock), check its status:

(a) Turn off the device


(b) Press Power + Loudness down to enter Fastboot




(c) Connect to the PC and enter the command:


   fastboot oem device-info


(d) See Device unlocked: false, which means that the bootloader is locked

3. Lack of root rights and custom changes

Make sure that:

• 🔍 There is no SuperSU or Magisk Manager option in the Settings menu.
• 🛠️ B Settings → The phone. → Version. MIUI No inscription Unlocked or Custom.
• 📱 Apps like Root Checker show no root rights.

4. Operation of all functions

Check it out.

• 📶 Mobile network (calls, SMS, mobile).
• 📶 Wi-Fi and Bluetooth.
• 🔋 Charging (plug the charger and make sure it is charging).
• 🎵 Sound (speakers, microphone, 3.5 mm connector, if available).
• 📷 Cameras (front and main).

If at least one of the features is not working properly, it may be that the firmware was chosen incorrectly or that the process was flawed, in which case repeat the firmware or contact the service center.
