You turned on a Xiaomi smartphone, and instead of your desktop, you saw a black screen, endless boot, or the word No command? Probably the firmware came off, a critical bug that turns the device into a brick. The reasons can be different: a failed MIUI update, an interrupted reset, experiments with custom firmware, or even hardware failures. The good news is that in 90% of cases, the phone can be brought back to life without going to the service center.
In this article, we will discuss all the working ways to restore firmware on Xiaomi, Redmi and POCO smartphones, from a simple reset via Recovery to flashing through Fastboot and Mi Flash Tool. You will learn how to determine the type of failure, where to download official software, and what errors can turn a phone into a hopeless “brick.”
We warn you right away that the recovery process requires care, and one wrong action, and instead of a software failure, you get a hardware breakdown, but if you follow the instructions and use proven tools, the chances of success are close to 100 percent, and let's start with diagnosing the problem.
How to understand that the firmware flew: symptoms and diagnosis
The first step is to determine that the problem is in the firmware, not the hardware (for example, a damaged motherboard).
- 📵 The phone turns on but gets stuck on the logo MI or Redmi (infinite bootloop).
- 🔄 After activation, the inscription No command or Recovery menu appears.
- 🖥️ The screen flashes, artifacts appear, or the system is constantly rebooted.
- 🚫 The device does not respond to charging (the indicator does not burn) or is determined by the computer as Qualcomm HS-USB QDLoader 9008.
- 🔧 In Fastboot (boot mode), the phone is detected but not loaded into the system.
If any of these symptoms are present, the problem is probably programmatic, but there are exceptions:
⚠️ Note: If the phone doesn’t respond to the power button, doesn’t warm up when charging, and isn’t detected by the computer even in Fastboot mode, the cause may be hardware failure (e.g., a memory chip dump or a power controller damage). In this case, the firmware repair will not help - repair is necessary.
To make sure you are diagnosed, try Recovery or Fastboot:
- 🔘 To enter Recovery: Turn off the phone, pinch the power + Volume up for 10-15 seconds.
- 🔘 To enter Fastboot: turn off the phone, pinch the power + Loudness down.
If you have any modes available, you can restore the firmware. If you don't, read the section on memory-damaged bricks.
Causes of the firmware failure: why it happened
Xiaomi's firmware can go down for a variety of reasons, and understanding the root of the problem will help you choose the right recovery method.
| Reason. | How it manifests | Method of recovery |
|---|---|---|
| Interrupted MIUI Update (via OTA or Recovery) | Infinite download, Update failed error | Re-update via Recovery or Fastboot |
| Failed resetting of settings (Wipe data) | Loaded load animation, No OS installed error | Installation of firmware through Mi Flash Tool |
| Install custom firmware (for example, LineageOS) | Bootloop error, lack of IMEI, sensor problems | Return to stock firmware via Fastboot |
| Damage to /system or /boot partition | The phone doesn't boot up, but the Fastboot is working | Reflash all partitions through the Mi Flash Tool |
| Hardware failure (damage to the eMMC or controller) | The phone is not detected by a computer, does not warm up. | Repair or replacement of motherboard |
Especially often problems arise when:
- 🔄 Updates through OTA Low battery charge (less than 50%).
- 🔧 Unlocking the bootloader in violation of instructions (for example, missing the Mi Account binding).
- 📱 Use of unofficial firmware without checking compatibility with the model.
- ⚡ Resetting settings through non-standard methods (e.g. commands) ADB backup).
A critical mistake many users make is trying to flash the phone through informal tools (such as the SP Flash Tool for Mediatek) without unlocking the bootloader, which leads to a complete lock on the device and requiring authorization through the Mi Account, even if there was no prior link.
Preparing for Recovery: What to Do Before Starting
Before you start repairing your firmware, prepare everything you need to do so that you can save time and prevent additional problems.

Now, more details on each item:
1. Determination of the model and firmware version
Even if the phone does not turn on, the model can be recognized by:
- 📦 Box (the sticker shows the full name, for example, Redmi Note 10 Pro).
- 🔋 Battery (some models have a sticker with a code, for example, m2101k7ag).
- 🖥️ Fastboot mode: connect your phone to your PC, open Command Prompt and type: fastboot getvar product This will display the model code (e.g., cepheus for Xiaomi Mi 9).
Knowing the code of the model, download the firmware from the official website:
🔗 https://new.c.mi.com/global/miuidownload/index (Choose the Stable version, not the Developer version, if you are not sure).
Installation of drivers
Without the right drivers, your computer won’t see your phone in Fastboot or EDL modes.
- 🖥️ For Mediatek: 💡If the phone is not responding to charging, try holding the power button pressed for 30 to 60 seconds. Sometimes this resets the power controller and restores charging. Method 1: Recovery: If your phone is loading into Recovery, try this method. It's suitable for cases where the firmware is not critical, such as after a failed update. MIUI. Instructions: Turn off the phone, then pinch the power + Volume up to enter Recovery. Select language (if menus are available). On older versions of Recovery, volume and power buttons control. Go to Wipe & Reset → Wipe All Data (this will delete all data, but restore functionality). After reset, select Reboot → Reboot to System. If the reset didn’t help, try installing firmware via Recovery: Download firmware in.zip format (for example, download firmware in.zip format, miui_BLOCKOTA_*.zip) from the official website. Rename the file to update.zip and copy it to an external microSD or to the root of internal memory (via the OTG-In Recovery, select Install. update.zip Wait until the installation is complete and restart the phone. ⚠️ Note: If after installing firmware through Recovery, your phone loads into Fastboot with an anti-rollback error, you are trying to install an older version. MIUI, In this case, you need a full reset via the Mi Flash Tool. 💡Recovery only works if the partition is not damaged, but, for example, the cache or user data. If the phone does not boot again after reset, go to the methods via Fastboot. Method 2: If Recovery is unavailable or unhelpful, use Fastboot, a bootloader mode that allows you to flash your phone even with severe firmware damage. POCO, but requires an unlocked bootloader (if it has been locked before: 🖥️ Computer with installed drivers (see section "Preparation»). 📱 Firmware in.tgz or.zip format (download the Fastboot version from the official website). 🔧 The Mi Flash Tool (you can download it here). 🔑 Unlocked bootloader (if previously blocked) Step-by-step: Unpack the downloaded firmware into a folder without Cyrillic characters (for example, C:\Xiaomi\proshivka). Install the Mi Flash Tool and launch it on behalf of the administrator. Turn off the phone and pinch the Power. + Volume down to enter Fastboot. Connect your phone to your computer through USB. In Mi Flash Tool, click Select and select the folder with the unpacked firmware. At the bottom, select firmware mode: 🔄 Clean all – complete cleaning (recommended in case of serious failures). 🔄 Clean all and lock - cleaning + Locking the bootloader (only if you need to return the phone to the stock state). 🔄 Save user data – data retention (not always working).
If the process ends with an error, check:
- 🔌 Cable and port USB (Try another cable or port on the back of your PC).
- 🔧 Mi Flash Tool (new models require the latest version).
- 📁 The path to firmware (should not be Cyrillic or gaps).
- 🔒 bootloader status (if blocked, unlock through the official website).
What to do if the Mi Flash Tool gives you a “flash not done” error
Method 3: Firmware through EDL (for “bricks”)
If the phone doesn’t load even in Fastboot and is defined as Qualcomm HS-USB QDLoader 9008, then the bootloader or critical partitions are damaged, in which case only firmware through EDL (Emergency Download Mode), an emergency mode for devices on Qualcomm chips, will help.
Warning: This method requires authorization through a Mi Account (for new models) or the use of paid tools like the Mi Flash Pro.
Instructions:
- Download the firmware for EDL (usually a file with the.mbn or.elf extension).
- Install the Qualcomm 9008 driver (can be accessed via XDA Developers).
- Connect your phone to your PC – it should decide how to do it. QHUSB_BULK qualcomm HS-USB QDLoader 9008.
- Use one of the tools: 🖥️ Mi Flash Tool (requires authorization for new models). 🖥️ QFil (for firmware in.mbn format). 🖥️ EDL Tool (paid but supports all models).
Pick a firmware and start the process. It takes 10 to 20 minutes.
Fastboot
⚠️ Attention: Firmware through EDL Unauthorized can lead to blocking IMEI For models Xiaomi 2020 and later requires an official developer account with a reference to the device.
If you have a model on a Mediatek processor (for example, Redmi 9A or POCO C3), instead of EDL, you use BROM mode. For firmware, you will need the SP Flash Tool and the scatter.txt file from firmware.
What to do if nothing helps: hardware problems
If all firmware recovery methods fail, the problem may be hardware, and here are the most common non-software reasons:
- 💾 EMMC memory damage: phone not detected in any mode, not warmed, not charged.Requires replacement of memory chip.
- ⚡ Power controller malfunction: phone doesn’t respond to charging, but sometimes wakes up from connecting to PC.
- 🔌 The plume or contacts dump: after falling or hitting, checked by disassembly.
- 📡 Problems with antennas or modem: phone turns on but no network or IMEI.
How to diagnose a hardware problem:
- Check if the phone warms up when you connect to charging (if so, the power controller is working).
- Connect to a PC: If a device isn’t even defined as Unknown Device, it’s likely the hardware problem.
- Light a flashlight on the screen: if the image is barely visible - the illumination or plume of the display is faulty.
In such cases, self-repair is not possible - contact the service center.
| Problem. | Cost of repair (ruble) | Timeline |
|---|---|---|
| Replacement of eMMC (memory) | 3 000 – 8 000 | 1-3 days |
| Repair of the power controller | 2 000 – 5 000 | 1-2 days |
| Pillowing | 1 500 – 3 000 | 1 day |
| Rebuilding IMEI | 1 000 – 2 500 | 1 hour |
If the phone is warranty, don't try to sew it yourself - this will void the warranty. Take it to the official Xiaomi service center with a check.
