Many users of Xiaomi, Redmi and POCO devices are wondering how to get into the BIOS, but technically on Android smartphones, this concept does not exist in the classical sense of personal computers. Instead of the usual BIOS, it uses a Bootloader loader, and special modes are designed to deepen the system: Recovery Mode and Fastboot. These hidden partitions allow you to reset to factory settings, reflash the device, install customized recoveries or unlock the bootloader to obtain advanced rights.
The need to enter these modes most often occurs when software failures when the phone stops booting, or if enthusiasts want to modify the operating system MIUI or HyperOS. It is important to understand that manipulation of system partitions requires caution, since incorrect actions can lead to the failure of the gadget. In this guide, we will discuss in detail all available methods of logging into the service menu, the necessary combinations of buttons and software methods of interacting with the device via the computer.
Why there is no classic BIOS on smartphones
The architecture of mobile processors, whether it is Snapdragon, MediaTek or Helio, is radically different from the architecture of desktop PCs, which eliminates the presence of traditional BIOS with a graphical interface. In smartphones, the functions of the basic I/O system are performed by a bootloader that initializes the hardware and runs the Android operating system. The user interface is absent at this stage of the boot, and all the settings that are in the PC in the BIOS, in phones are either blocked by the manufacturer or accessible through hidden engineering codes and special modes.
The main analogue of the BIOS for Xiaomi users is the Recovery mode, which is a minimalist operating environment for maintaining the device. This is where you can perform Wipe Data (full reset), clear the cache or install a manual update. Another important access level is the Fastboot mode, which is designed for low-level debugging and firmware memory partitions directly from the computer, making it a powerful tool in the hands of a specialist.
⚠️ Note: Logining to system menus and changing bootloader settings may cancel the device warranty. Be extremely careful when choosing actions in the Recovery menu, especially when confirming a data reset.
Understanding the differences between these modes is critical before any work begins. If Recovery is end-user-oriented and contains basic recovery features, Fastboot is a tool for developers to intervene in memory partitions at the code level. For the average user trying to reanimate a phone after hanging, knowledge of the first mode is usually enough.
Preparation of the device for entering the system menu
Before trying to log into service sections, you need to perform a number of preparatory steps that will ensure the success of the operation and data security. First of all, make sure that the device battery is charged at least 50-60%, as the process of flashing or resetting can take time, and a sudden power outage at this point is fatal to the file system. It is also recommended to back up important contacts, photos and documents, since entering some modes involves automatic memory cleaning.
To work with the Fastboot mode, you will definitely need a proper one. USB-cable, preferably original, and a computer with installed Xiaomi drivers USB Drivers. Without the right drivers, the computer won't be able to recognize the phone in bootloader mode, and you'll only see the connection of an unknown device. In addition, to unlock the bootloader in modern models, you need an activated Mi Account account and associate the device with it in the settings.
☑️ Preparing for Recovery and Fastboot login
Special attention should be paid to the state of the control buttons. The mechanical volume and power keys should be working, since the modes are entered by a combination of their presses. If the button is stuck or has a bad contact, you may not be able to enter Recovery the first time. In such cases, it sometimes helps to easily tap the body in the button area or use software methods through ADB.
Recovery Mode Login Methods on Xiaomi
Recovery Mode is the most accessible and frequently used partition for solving software problems. There are two main types of Recovery: standard (Stock), which has limited functionality in both Chinese or English, and custom (for example, TWRP), which is set by users for advanced features. To log into the standard menu on the device you need to pinch the key combination.
The classic entry pattern for most Xiaomi and Redmi models is this: turn off your smartphone completely, then press the Volume Up and Power button at the same time. Hold both buttons until the Mi or Redmi logo appears, after which the power button can be released, continuing to hold the volume key. When the menu with several points in English or Chinese appears on the screen, the buttons can be released.
- 📱 On some models with a side fingerprint scanner, the combination may not work unless you press buttons with a certain delay or force.
- 🔌 If the phone is connected to a charger or computer via USB, The button method may not work – turn off the cable.
- 🔄 In rare cases, you need to press the volume button several times after the logo appears to switch between modes.
Navigation in the Recovery menu is done with volume buttons (up/down), and the choice of item is confirmed by the power button. In some new versions of MIUI, navigation can be touch-sensitive, but this is rare. The main menu contains items: Reboot (reboot), Wipe Data (data reset), Connect with MIAssistant (connect to a PC) and Safe Mode (safe mode).
💡
If the Recovery menu appears in Chinese, look for the characters corresponding to the Reboot item to exit, or use the translator on your phone for the Wipe Data item.
How to enter Fastboot mode (Hare mode)
Fastboot mode, often referred to by users as “hare mode” because of the characteristic image of a hare repairing an android, is designed for low-level modification of the system. In this state, the phone does not load the operating system, but goes into standby mode for commands from the computer. This is the main way to officially unlock the bootloader through the Mi Unlock utility and flash the device through the Mi Flash Tool program.
To enter this mode on the off smartphone, you need to press the Volume Down button and, without letting it go, connect the device to the computer through USB-The screen should light up, and you'll see a hare in a hat with a sign that says, FASTBOOT. If the phone is on, you have to turn it off completely beforehand. In some cases, if the phone is getting stuck, you can try to press the power button on the phone. 10-15 seconds to force shutdown, and then immediately perform the combination.
| Regime. | Button combination | USB connection | Appointment |
|---|---|---|---|
| Recovery | Volume Up + Nutrition | Not required | Reset, upgrade, safe mode |
| Fastboot | Loudness DISCUSS + Power (or USB) | Definitely a PC. | Firmware, unlock, tests |
| Safe Mode | Choices in the Recovery menu | Not required | Diagnostics of third-party applications |
To exit Fastboot mode, it is usually enough to press the power button and hold it near. 10-15 If the standard method doesn't work, you can log in to the Recovery menu. + Power) directly from the mode of the hare, selecting the menu item Reboot. It is a universal way to get out of any cyclic state.
Use ADB and Command Line to Access
For advanced users who have access to the system with enabled debugging USB (USB Debugging, there is a software method of entering the desired modes without using physical buttons. This is especially true if the volume buttons are faulty or the device is in a state where mechanical pressing of the buttons does not work. ADB Drivers and Android Platform Tools SDK.
After connecting the phone to your PC and confirming the debugging request on your smartphone screen, open the command prompt or terminal in the folder with ADB. To go to bootloader mode, enter the command adb reboot bootloader. The device immediately reboots to Fastboot mode. If you want to get into the recovery menu, the adb reboot recovery command is used. These commands work at the kernel level of the system and are the most reliable software method.
adb reboot bootloader
adb reboot recovery
fastboot rebootAlso through ADB You can get detailed information about the status of the device by entering the command adb devices to check the connection or fastboot devices in boot mode, which makes sure that the computer sees the smartphone correctly and is ready to transmit commands. If the device is not displayed, check the installed drivers and integrity USB-cable.
Solution: The phone is not in modes
Xiaomi's smartphone ignores the buttons and just turns on normally is quite common. The main reason for timing is that users release the buttons too early or, conversely, too late. Try changing the rhythm of pressing: first press the volume button, then press the power, and only after the vibration or logo appears, release the power button, continuing to keep the volume.
Another common problem is the Bootloop state, where the phone is endlessly rebooted, and you can get to Recovery by waiting for the screen to go out before you turn on, and quickly clamp down the right combination. If nothing helps, try connecting the device to your computer via USB when it's off, and then press the buttons. Sometimes having an active connection from your PC changes the priority of interruption and allows you to enter the desired mode.
⚠️ Warning: If the phone is entering a reboot cycle and doesn't respond to buttons, the system partition may be damaged, in which case logging into the Fastboot and flashing through the Mi Flash Tool may be the only solution.
It’s also worth checking if the screen is locked by locking your account or if the bootloader password is not worth it, although the latter is rare on global versions. In some cases, logging in is blocked if the developer settings have disabled the corresponding option, but for standard button use scenarios this is not relevant, the main thing is patience and the right sequence of actions.
What to do if the buttons are physically broken?
Navigation and main commands in the system menu
Once in the Recovery menu, it is important to navigate the items correctly so as not to delete the extra. The menu usually consists of 5-6 lines. The Reboot item returns the device to normal operation. Wipe Data opens the submenu where you can choose Wipe All Data (full reset) or Wipe Cache (cleaning the cache, safe operation). Be careful: confirmation of a data reset often requires the input of a special word or code that is displayed on the screen, for example, "yes" or numbers.
In Fastboot mode, there is no navigation per se, the screen is static. All control is from the computer. However, by holding the volume and power buttons simultaneously for 10 seconds, you can call the Start Mode Selection menu (if supported by firmware), where you can choose between Normal Boot, Recovery and Fastboot. This is convenient if you happen to be on the wrong menu.
- 🛡️ The Safe Mode item in Recovery loads the system without user-installed apps, which helps identify the culprit of the failures.
- 🔍 In the Connect with MIAssistant menu, you can connect to your PC to reset your screen password (account required) or firmware.
- 📉 View Log (if any) allows you to view the error log of the last boot of the system.
To exit any menu without making changes, simply select Reboot and confirm the action (usually the first line on the menu).If the system is damaged critically, the phone may try to log in to Recovery again after the restart - this is a signal to need a complete flashing.
💡
Recovery mode is your main tool for saving software failures, allowing you to reset settings without losing warranty, unlike custom methods.
