How much time Xiaomi stitches through MiFlash: analysis by models and types of firmware

Firmware Xiaomi smartphones through MiFlash is standard procedure for system recovery, unlocking the bootloader or installing custom builds. But one of the most common questions users ask is: how long will this process take? The answer is not as clear as it seems. Time depends on the device model, firmware type (Fastboot or Fastboot). EDL), MiFlash Tool version, as well as the hardware of your PC.

In this article, we will take a detailed look at all the factors that affect firmware duration, provide real time measurements for popular Xiaomi models (2018-2026), and give recommendations on how to speed up the process or avoid freezes, POCO F5 Xiaomi 14 flagship – here you will find the latest data.

1. What is the time of firmware through MiFlash?

Firmware speed is influenced by at least 5 key factors, and let’s take a look at them in detail so you can estimate how much time you’ll spend.

The type of firmware is the main parameter:

• 🔹 Fastboot firmware (standard mode): takes 3 to 15 minutes, suitable for most tasks - system recovery, upgrade or downgrade.
• 🔹 EDL-Firmware (emergency mode): lasts 15-25 minutes, and is used for “brick” devices when the Fastboot is unavailable.
• 🔹 Custom firmware (e.g. LineageOS): time depends on file size, but usually 5-12 minutes.

The smartphone model and its “iron”:

• 📱 Budget models (Redmi) 9A, POCO M3): They are faster (3-8 minutes) because of the chipset and small amount of memory.
• 📱 Flagships (Xiaomi 13 Ultra, Black Shark 5 Pro): can take up to 20 minutes due to the complex partition structure and large amount of data.
• 📱 Devices with UFS 3.1/4.0 (for example, POCO F6 Pro: bent on 20–30% faster than eMMC models.

Also playing a role:

• 💻 PC performance: a weak laptop with HDD It can slow down the process at the stage of unpacking the firmware.
• 🔌 Type of connection: USB 2.0 vs USB 3.0/3.1 — difference in data transfer speeds before 10 once!
• 📦 Size of firmware: stock MIUI Xiaomi 14 weighs in ~4GB, and for Redmi. A2 — everything ~1.5 GB.

2.Real firmware time for popular Xiaomi models

We tested the firmware through MiFlash 2026.4.1 on different devices using official Fastboot firmware, the results are in the table below (time is indicated for a full cycle: from connection to reboot).

It's important! Time can increase if:

• 🔋 The battery is discharged below 30% (we recommend charging up to 50%+).
• 🖥️ PCs run resource-intensive programs (such as games or video rendering).
• 🔄 Used unofficial firmware with modified scripts.

⚠️ Note: If the firmware through Fastboot lasts more than 20 minutes, it is a sign of a problem. USB-Cable or driver conflict. interrupt the process (disable the device with Power retention) + Vol Down for 10 seconds and check the connection.

3. Step-by-step: How to flash Xiaomi through MiFlash fast

To minimize firmware time, follow this algorithm, and we've optimized each step to speed up the process.

Install the latest version of the MiFlash Tool (2026.4.1+)|Download the firmware for your model from the official website (for example, https://new.c.mi.com/global/miuidownload/index)|Disable antivirus on PC (it can block drivers)|Connect the smartphone to the original USB-cable USB 3.0 (blue-jack)|Charge your phone to a minimum. 50%-->

Step 1: Installation of drivers

Download and install:

• 🔧 Mi Phone Manager (Automatically Installs Drivers).
• 🔧 Android SDK Platform-Tools (for fastboot teams).

For EDL-The mode will require additional Qualcomm driver HS-USB QDLoader 9008 (see in the archive with firmware or on the 4PDA).

Step 2: Preparation of firmware

Unpack the downloaded archive with firmware in a folder without Cyrillic (for example, C:\Xiaomi\ROM). Inside should be an image folder with.img files.

Professional life hack: if the firmware weighs more than 4 GB, unpack it on SSD — This will speed up reading files by 30 to 40%.

Step 3: Launching MiFlash

1. Open MiFlash on behalf of the administrator.
2. Click Select and point the way to the folder with unpacked firmware.
3. Connect the phone to Fastboot (Plug Vol Down) + Power).
4. In MiFlash, select the firmware method: clean all – complete cleaning (recommended for changing the region). clean all and lock – cleaning + Save user data – saving user data (not always stable).

Step 4: Waiting and restarting

Once the green tick appears in MiFlash (Flash Done), the device will reboot automatically. USB-cable until you see the logo MI screen-on.

1. Reconnect. USB-cable.

2. Run MiFlash in Windows 8 Compatibility Mode.

3. disable driver signatures in Windows (via gpedit.msc).-->

4. Why is the firmware running through MiFlash taking too long?

If the process is delayed (more than 20 minutes for Fastboot or 30 minutes for Fastboot) EDL), Check out these moments:

1.Problems with USB-connection

• 🔌 Cable: Use the original Xiaomi cable or certified cable USB-C 3.1 Cheap cables can "cut" speeds to USB 2.0.
• 🖥️ Port: Connect to the rear ports of the system unit (they are usually faster than the front ports).
• 🔄 Hub: Don't use it USB-Hubs – They create delays.

2. Driver conflict

If your Xiaomi displays with an exclamation point in Device Manager:

1. Remove all devices with the names Qualcomm, Android, Xiaomi.
2. Turn off driver signature verification: bcdedit /set testsigning on bcdedit /set nointegritychecks on
3. Reinstall the driver via Mi Phone Manager.

3. PC resource shortage

MiFlash is actively using the CPU And the disc:

• 💾 HDD: unpack the firmware on SSD (speed up the process by 40%).
• 🖥️ Weak CPU: Close all background programs (especially a browser with a dozen tabs).
• 🧹 Little RAM: Increase the paging file to 8GB.

⚠️ Warning: If MiFlash freezes 99% longer than 5 minutes, that's a critical mistake. Don't breathe on the device and don't wait for a miracle: force the phone to restart (press the Power for 20 seconds) and start over. USB-port-over.

5. Fastboot vs EDL: What mode to choose to save time?

The choice between Fastboot and EDL It depends on the state of your device. Let's look at the pros and cons of each method.

Fastboot firmware

• ✅ Fast: 3-15 minutes (depending on the model).
• ✅ Simple: No additional drivers (except standard ones) ADB).
• ✅ Safe: Less risk of “bricking».
• ❌ Limitations: Does not work if the device does not turn on or the bootloader is blocked.

EDL-firmware

• ✅ Rescues the “bricks”: restores devices with a damaged loader.
• ✅ Full control: Switches through all partitions, including boot and recovery.
• ❌ Slowly: 15–25 minutes, even on modern models.
• ❌ Difficult: Requires a QDLoader driver and often manually login to 9008 mode.

When to choose EDL?

• 🚨 The device does not respond to buttons and does not load.
• 🔒 bootloader is blocked and Fastboot is not available.
• 📱 You need to flash boot or recovery separately (for example, for installation). TWRP).

How to enter EDL-regime?

1. Turn off the phone.
2. Hold Vol Up. + Vol Down and connect to the PC.
3. Device Manager should appear Qualcomm HS-USB QDLoader 9008.

6.How to speed up Xiaomi firmware through MiFlash?

If you need to save time, use these tips:

1. Optimize the PC

• 🖥️ Disable Antivirus: Avast, Kaspersky or Windows Defender can inhibit access to files.
• 🧹 Clean the disk: the system disk should have at least 10 GB of free space.
• 🔧 Update your drivers: Use Snappy Driver Installer to automatically update.

2. Choose the correct firmware mode

• 🔄 If you just need to update the system, use save user data (saves 2-3 minutes).
• 🗑️ If you want a complete cleanup, choose clean all, but be prepared for data loss.

3.Use alternative tools

For some Xiaomi models, there are faster tools:

• 🛠️ XiaoMiTool V2 — Automates the firmware and selects the optimal settings.

4. Switch in parts (for experienced)

If you don't need a full firmware, you can flash only the necessary partitions, for example, to restore the system, you can:

fastboot flash system system.img


fastboot flash boot boot.img

It will take 1-2 minutes instead of 10.

💡

The fastest way to flash Xiaomi is to use Fastboot mode with pre-unpacked firmware on the device. SSD, original USB-And you have a 3.1 cable and you have the antivirus turned off, and in this case, even the flagships are flashed in 6-10 minutes.

7. Frequent mistakes and how to avoid them

Firmware errors not only increase time, but they can also build up a device, and we'll take a look at some of the most common ones.

Flash is not done (red line in MiFlash)

Causes and solutions:

• 🔌 Poor connection: check out USB-cable.
• 📂 Damaged firmware files: download the archive again and check the checksum (MD5).
• 🔧 MiFlash incompatible: For new models (Xiaomi 14, Redmi Note 13) use MiFlash 2026.4.1+.
