You turned on your Xiaomi smartphone, and instead of your desktop, you had a black background with a green Mi Bunny robot and the words FASTBOOT? Don't panic, it's not a brick, but a special engineering mode that is used to firmware, unlock the bootloader or restore the system. However, if the phone is getting stuck in the Fastboot and does not respond to buttons, urgent intervention is required.
80 percent of the time, the problem is solved without losing data, like restarting the device or resetting the cache, but if it's a firmware failure, system file corruption, or custom backup conflict, you'll need a deeper intervention, from manual flashing through MiFlash to full reset to factory settings. In this article, step-by-step instructions for all scenarios, including when the phone isn't detected by a computer or when it comes out remote: unknown command.
Important: the algorithm of actions depends on the Xiaomi model (Redmi series, POCO, Mi), the firmware version (MIUI Global/China/EEA) and the status of the bootloader (unlocked/locked).We will analyze universal methods, as well as nuances for popular devices - from Redmi Note 10 Pro to Xiaomi 13 Ultra.
Why Xiaomi Phone Is Loading In Fastboot: 5 Top Reasons
Fastboot mode is a low-level tool for interacting with Xiaomi bootloader, which is activated either manually (via a combination of buttons) or automatically when critical crashes occur.
- π Failed update MIUI β interruption OTA-a package or switch to an unstable firmware version (e.g., with MIUI 14 on beta version of HyperOS).
- π§ Conflict with custom recaveri - installation TWRP OrangeFox without unlocking the bootloader or with errors.
- π± Hardware failure β damage to the boot or recovery partition due to falling, overheating or wear of flash memory.
- π bootloader lock β if you tried to unlock the bootloader through Mi Unlock, but the process was interrupted.
- π₯οΈ MiFlash firmware error β for example, choosing the wrong firmware version (for another model or region).
On some models (such as the POCO F3 or Redmi K40), the Fastboot may appear due to a dynamic partition bug (super.img), in which case the system cannot mount system files and βlocks inβ during the boot phase.
Method 1: Simple reboot (works 60% of the time)
If a Xiaomi phone hit the Fastboot by accident (like clicking a button combination), try the standard reboot.This method doesn't delete data and takes less than a minute.
βοΈ Procedure for resetting
On most Xiaomi models (e.g. Redmi Note 12, POCO X5 Pro) it is enough to hold the power button for 10-20 seconds until the screen goes out.
- Press the power + volume up for 15-20 seconds at the same time.
- Release the buttons when the screen goes out (vibration will confirm the shutdown).
- Wait 30 seconds and turn on the phone with the power button.
β οΈ Note: On some devices (e.g. Xiaomi) 12T) Long-term button retention can lead to a hard reset, and if a menu with a choice of language appears on the screen, it's a sign of a factory reset.
If after the reboot the phone again gets into Fastboot, the reason lies deeper - you will need to clear the cache or flash it.
Method 2: Clearing the cache with Recovery Mode (without data loss)
If a simple reboot doesnβt work, the next step is to clear the boot and recovery partition cache, which removes temporary files that may block normal downloads but doesnβt affect user data (photos, messages, apps).
Instructions for entering Recovery Mode:
- Turn off the phone (hold power until vibration).
- Press Power + Volume up and hold until the Mi logo appears.
- Release the buttons and you will see the Recovery menu (in English or Chinese).
On the Recovery menu:
- π± Choose Wipe & Reset β Wipe Cache (use volume buttons for navigation, power to confirm).
- π Confirm the action and wait until it is completed (usually takes 10β30 seconds).
- π Go back to the main menu and select Reboot. β Reboot to System.
If the phone loads again in Fastboot after clearing the cache, try repeating the procedure, but this time select Wipe Dalvik Cache (if there is such an item on the menu).
π‘
On some models (e.g. Redmi 9A), the Recovery menu may be in Chinese. Look for characters (data cleanup) and (cache cleanup).
Method 3: Firmware through MiFlash (for unlocked bootloader)
If the first two methods donβt work, the system files are likely damaged, and then flashing through MiFlash, Xiaomiβs official tool for installing stock firmware, will help, requiring a computer and an unlocked bootloader.
What you need:
- π» Windows computer 10/11 (MiFlash needs Qualcomm or Mediatek drivers).
- π Cable USB (preferably original, with data transmission support).
- π Firmware for your model (download from the official website) MIUI Downloads).
- π Unlocked bootloader (if not, read the section about unlocking).
Step-by-step:
- Install MiFlash and drivers for your chipset (e.g. Qualcomm QDLoader for Snapdragon).
- Unpack the downloaded firmware (file with the extension.tgz or.zip) in a folder without Cyrillic characters.
- Launch MiFlash, press Select and point the path to the firmware folder.
- Turn off the phone and put it in Fastboot mode (hold Power + Volume down).
- Connect your phone to your PC. MiFlash should be determined. COM-port.
- At the bottom of the program, choose clean all (full cleaning) or clean all and lock (clean + lock the bootloader).
- Press Flash and wait until it is completed (usually 5-10 minutes).
| Mistake in MiFlash | Reason. | Decision |
|---|---|---|
| remote: device is locked | bootloader locked | Unlock through Mi Unlock (see section below) |
| flash write failure | A cable or USB port is damaged. | Try another cable/port or disable the antivirus |
| invalid sparse file | Firmware file damaged | Download the firmware again and check the checksum |
| device not found | Drivers not installed | Install MiPhoneManager or drivers manually |
β οΈ Note: If you choose clean all and lock, the bootloader will be locked and you will have to wait 720 hours to re-unblock (by Xiaomi rules.
π‘
The firmware via MiFlash deletes all data from the device. If you had important files, try to restore them first through ADB (if the phone is identified in Fastboot).
Method 4: Unlock the bootloader via Mi Unlock (if blocked)
If you try to flash your phone through MiFlash and see a remote error: device is locked, the bootloader is locked. Xiaomi blocks it by default to protect against unauthorized changes.
- Download the Mi Unlock Tool and install it on PC.
- Register a Mi Account and link to your phone (unless previously done).
- Enable debugging via USB and account binding in the developer settings (Settings β About Phone β MIUI version β tap 7 times, then go back to Additional settings β For Developers).
- Connect your phone to Fastboot and start Mi Unlock.
Important nuances:
- π After unlocking, you will have to wait 168 hours (7 days) before the first firmware.
- π± Some models (such as the Xiaomi 13 Pro) require SIM-card.
- π If the phone was bought with hands, the previous owner could link his account β in this case, unlocking is impossible without his data.
After successful unlocking, repeat the firmware via MiFlash (see Method 3).
What if Mi Unlock canβt see the device?
Method 5: Recovery through EDL Mode (for bricks)
If the Xiaomi phone doesnβt respond to any buttons, isnβt detected in the Fastboot, and doesnβt even vibrate when connected to charging, then the last chance is EDL (Emergency Download Mode) mode, which is an emergency mode for firmware to be run through a special cable or test points.
When you need an EDL:
- π± Remote: Partition table doesn't exist in MiFlash.
How to log into EDL:
- Connect a special one. EDL-cable (or close the test points on the board if you have experience soldering).
β οΈ Attention: Firmware through EDL delete all data without the possibility of recovery, including IMEI On some models (e.g. Redmi Note 9 Pro) after EDL Recovery may be required IMEI through SN Writer Tool.
Mediatek chipsets use BROM mode and SP Flash Tool instead of EDL. The algorithm is similar, but MediaTek Preloader drivers are required.
Method 6: Recover IMEI and serial number after firmware
If you have been using MiFlash or EDL The phone has lost its network (not caught) SIM-cards or gives an error invalid IMEI, This is a common problem when you get a bad firmware or reset through Recovery.
How to restore the IMEI:
- Find out the original IMEI (look at the box or sticker under the battery).
- Download SN Writer Tool (for Qualcomm) or Maui Meta (for Mediatek).
- Connect the phone in EDL mode (see Method 5).
- Enter the IMEI in the program and press Write.
Important:
- π± IMEI It must be the same as the one on the box or under the battery.
- π After recovery, restart your phone and check the network.
- β οΈ Don't use strangers. IMEI β This is illegal and may result in the operator blocking the device.
Method 7: Contacting the service center (guarantee cases)
If all of these methods did not help, or you are not sure of your skills, it is better to contact the official service center Xiaomi.
- π§ Phone for warranties (self-supported firmware cancels the warranty!).
- π₯ Hardware failure (for example, damage to flash memory or power controller).
- π± Loss of loss IMEI after a failed firmware (the service will restore data from the chip).
- π bootloader blocked by previous owner (purchase confirmation required).
Cost of repair in unofficial services:
| Type of work | Cost (β½) | Timeline |
|---|---|---|
| Firmware through EDL | 1 500 β 3 000 | 1-2 hours |
| Rebuilding IMEI | 1 000 β 2 500 | 30-60 minutes |
| Replacement of flash memory | 4 000 β 8 000 | 1-3 days |
| Unlock the bootloader (if blocked by the account) | 2 000 β 5 000 | 1 day |
Before the service visit:
- π Take a check or a warranty card (if the phone is guaranteed).
- π Charge your phone at least 30% (if it reacts to charging in any way).
- π± Check with the wizard if they work with your model (some services do not take on Xiaomi on Mediatek).
