Every Xiaomi smartphone owner will sooner or later face the need to go beyond the standard operating system interface, which may involve updating the firmware, resetting a forgotten password or installing a custom recap. For such tasks, Android architecture has special low-level modes that are accessed before the system is fully loaded. Understanding their work is the key to self-service device.
In this article, we will discuss in detail the two main engineering modes: Fastboot and Recovery. You will learn what their fundamental difference is, what actions can be performed in each of them, and how to safely enter these modes on Redmi and Poco devices.
What is Fastboot Mode and Why You Need It
Fastboot is a protocol developed by Google to debug and modify the Android file system via the Internet. USB-On Xiaomi devices, this mode is the main tool for deep flashing, unlocking the bootloader and restoring the system after critical failures. Unlike normal OS operation, Fastboot gives direct access to the device's memory partitions.
When the smartphone is in that state, the operating system doesn't boot. Instead of the desktop, you see a screen with the Fastboot logo and a picture of a rabbit repairing an android. In this mode, the device waits for commands from the computer. ADB (Android Debug Bridge) is not used here, instead it uses a special set of instructions transmitted over USB.
The mode’s main features include writing new partition images, erasing data, and checking device status, a critical tool for software modifications, but using commands carelessly can lead to a complete failure of the gadget.
⚠️ Warning: Being in Fastboot mode is safe in itself, but executing commands to write (flash) without verified firmware can turn a smartphone into a “brick.” Always check for file compatibility.
There are two options for working with this protocol: the regular Fastboot and FastbootD. The second is part of Project Treble, which allows you to update system partitions that were previously protected.
How to enter Fastboot mode on Xiaomi
The process of transitioning to fast boot mode on Xiaomi smartphones is standardized and performed by a combination of physical buttons. It is important to understand that the device must be completely turned off before the procedure begins. If the phone freezes, you must forcefully restart it, holding the power button for about 10-15 seconds.
When you turn it off, press the Volume Down and Power button at the same time, and hold them until the characteristic picture of a hare and the words Fastboot appears on the screen. This usually takes 3 to 5 seconds. Once the image appears, the buttons can be released.
If the phone just turned on as a hare, you've pressed the buttons too late or didn't click them. Try again, making sure the phone was completely off. Some models with a side fingerprint scanner (which is paired with a power button) need to be especially careful not to unlock the device before the time.
💡
If the screen does not light up, connect the phone to a charged battery or computer through a USB-cable before attempting to enter mode.
To get out of this state, you just hold the power button for 10-15 seconds. The device vibrates and reboots in normal mode. If a software failure blocks a normal reboot, you may need to wait for the battery to drain completely, but on modern Mi and Redmi this happens extremely rarely.
Recovery mode: types and differences Stock from Custom
Recovery is a separate, minimalist Android operating system mode designed to serve the device. It allows you to run backups, reset to factory settings and install updates. Xiaomi smartphones have a stock (official) backup by default, which has limited functionality and closed source code.
There are two main types of Recovery: Stock Recovery, a factory program with a simple menu, often controlled through touchscreen or volume buttons, and it can only do basic things: clean up data (Wipe Data) and apply updates (Apply Update); Custom Recovery (like TWRP) is a third-party program with advanced functionality that allows you to make full copies of the system, format individual partitions and install modified firmware.
The main difference is the access layer: the stock recavator checks the digital signature of the files being installed. If you try to put the modified firmware through the official mode, the system will give an error in verifying the signature. The cavity recavator removes these restrictions, but requires the bootloader to be unlocked beforehand.
| Function | Stock Recovery | Custom Recovery (TWRP) |
|---|---|---|
| Resetting settings | Yes. | Yes. |
| Installation of official updates | Yes. | Yes. |
| Full system backup | No. | Yes. |
| Installation of custom firmware | No. | Yes. |
| File system operation | Limited. | Full access |
For users who do not plan to experiment with custom software, stock mode is sufficient, it provides stability and security of data, preventing the installation of corrupt or malicious system files.

Stock Recovery is a first aid kit from the manufacturer, and Custom Recovery is a surgical tool for enthusiasts.
Navigation and basic Recovery menu features
The recovery menu on Xiaomi devices is logged in with a combination of Volume Up and Power buttons. Unlike the Fastboot, the Mi logo often appears here, then menus open. On newer versions of MIUI and HyperOS, the menu can be touch-sensitive, but navigation with volume buttons (up/down) and confirmation of the power button remain functional.
You'll see a few items in the list of options available. The most useful for the average user is Wipe Data, which allows you to completely reset your device (Wipe All Data) back to factory status, or reset only (Wipe All Data without cleaning internal memory, although Xiaomi often erases everything), which you need to do when you sell your phone or before you send it for repair.
Another important item is Connect with MIAssistant, which puts the phone into a Fastboot-like mode, but with the option of using the official Mi Flash Tool to restore the system through the computer, which is handy if the standard air update (OTA) doesn't work.
⚠️ Note: Wipe Data permanently deletes all photos, contacts and applications.Be sure to back up important data in the Mi Cloud cloud or on your computer before using this item.
There may also be a Safe Mode option on the menu (on some versions) that allows you to boot with third-party apps disabled, which helps diagnose problems caused by newly installed programs, and if the phone is running in Safe Mode normally, then the problem is in one of your apps.
Using ADB and Fastboot commands for advanced users
To interact with your phone in Fastboot mode from your computer, you need a set of Google Platform-tools. Once you install Xiaomi drivers and adjust the environment variables, you can send commands through the terminal, which gives you complete control over the device, bypassing the graphical interface.
One of the most important commands is to check the bootloader status, and by typing a command in the terminal, you can see if Bootloader is locked, which is critical before you start any firmware manipulation, and you can force the phone to restart to any other mode through Fastboot.
fastboot rebootThis command will return the device to normal operation mode. To move to Recovery, the following instructions are used:
fastboot reboot recoveryIn addition, Fastboot provides the serial number of the device and other technical details, which are useful for identifying the device in service centers.
☑️ Checking before entering Fastboot commands
Typical problems and ways to solve them
Often, users are faced with a situation where the phone itself enters Recovery or Fastboot mode when turned on, this may indicate a sticking of the volume buttons, damage to the plume or a critical error in the boot partition of the system. If the buttons are correct, the file system is most likely damaged.
In the case of a “bootloop” where the phone is constantly restarting and cannot start Android, logging into Recovery via a button combination is the only way to save the device. Executing the Wipe All Data command solves the problem 90% of the time if it is caused by a software conflict after a failed update.
If the computer doesn’t see the phone in Fastboot mode, the problem often lies in the drivers or the phone’s sensing. USB-Use the original cable and port. USB In Windows Device Manager, the device must appear as Android Bootloader Interface. If there is a question mark or “Unknown Device”, you must manually update the driver.
⚠️ Warning: Do not attempt to unlock the bootloader if the phone's battery is less than 50% charged. Interrupting the unlocking process due to battery discharge can cause irreversible damage to the boot sectors.
To diagnose hardware problems, you can use the CIT test menu, which is called by the code ##64663## in dial mode, if the phone is at least partially functional, to check the touchscreen, vibrator and buttons.
