Fastboot mode on Xiaomi smartphones is a low-level tool that allows you to access system parts of the device, bypassing the Android operating system. It is often confused with Recovery mode, but the functions they have are fundamentally different: If Recovery allows you to reset settings or install ZIP-archives with firmware, Fastboot gives direct control over the bootloader, unlocking the bootloader and firmware of individual partitions through the PC.
For most Xiaomi users, this mode remains a “dark forest” until you need to unlock the bootloader, flash custom software or restore a “brick” phone. Meanwhile, ignorance of the nuances of working with Fastboot can lead to irreversible loss of warranty (if the device was not officially unlocked through Mi Unlock) or even to a complete failure of the smartphone. In this article, we will discuss what a Fastboot is in practice when it is really needed, and how to use it without risks.
Let’s warn you right away: if you’ve never encountered smartphone firmware via PC, it’s best to first learn the theory.Fastboot is not a tool for “trying something new,” but a professional mode where a mistake in one command can turn your Redmi or your own. POCO But when you do it right, it's the key to expanded capabilities, from global firmware installations to custom cores to modified recavities.
What is Fastboot and Why You Need It on Xiaomi
Fastboot mode is a protocol for interaction between a smartphone and a computer that is activated before the operating system starts. Unlike normal onset, when the bootloader transfers control to the Android kernel, Fastboot leaves control to the user.
- 🔓 Unlock the bootloader officially via the Mi Unlock Tool or unofficial methods (with risks!).
- 📥 Switching separate sections (for example, boot.img, recovery.img, system) without complete flashing.
- 🛠️ Restore “brick” devices when the phone doesn’t boot even in Recovery.
- 🔄 Install custom Recovery (TWRP, OrangeFox) for further rooting or modifications.
On Xiaomi smartphones, Fastboot mode is implemented in accordance with the company’s policy: by default, the bootloader is locked, and most operations (except for basic commands like fastboot devices) require its unlocking, this is done for the sake of security – so that attackers can not easily access user data through physical access to the device.
However, there is a caveat: even after unlocking the bootloader, some Xiaomi models (especially new ones starting with the Redmi Note 11 and Xiaomi 12) can block the firmware of unofficial images through the Fastboot due to the Anti-Rollback mechanism.
⚠️ Note: If your Xiaomi is released after 2021, be sure to check the Anti-Rollback version in the current and target firmware before running through Fastboot. IMEI or a broken chamber!

Unlocking the bootloader via Fastboot: official and unofficial methods
The bootloader on Xiaomi smartphones is locked by default, meaning that any attempts to flash custom software or modified recovery through Fastboot will be blocked. There are two ways to unlock it:
Official method (recommended)
Xiaomi provides the Mi Unlock Tool utility, which unlocks the bootloader after linking the Mi Account to the device.
- Download Mi Unlock Tool from the official website.
- Log in to Fastboot on your phone and connect it to your PC.

- Follow the instructions (usually 72-168 hours of waiting for new accounts)
Unofficial methods (at your own risk)
If official unlocking is not available (for example, due to region restrictions), some users use workarounds:
- 🔗 Exploits for older models: on devices before 2019 (for example, Redmi Note 7) it was possible to unlock the bootloader through vulnerabilities in fastboot oem unlock-go.
- 📦 Patched firmware: Some custom software (such as Xiaomi.eu) is installed on top of a blocked bootloader, but this is fraught with bugs.
- 💻 EDL-Unlocking: requires an authorized Xiaomi account and special hardware (e.g. Deep Flash Cable).
Important: Unofficial unlocking can lead to a ban of Mi Account (with loss of access to cloud data) or hardware lock on new models (for example, Xiaomi 13 or Redmi). K60).
| Unlocking method | Suitable models | Risks. | Whether waiting is required |

Frequent Fastboot Errors and How to Fix Them
Working with Fastboot on Xiaomi is often accompanied by errors that can confuse even experienced users.
Error 1: Fastboot: Error: Failed to boot into fastbootd
Reason: Trying to switch to fastbootd (Advanced Fastboot mode) on devices where it is not supported (e.g. older models on the Fastboot mode). MTK).
Solution: Use the standard fastboot commands without the d suffix.
Error 2: Device not found or an empty list in fastboot devices
Causes and solutions:
- 🔌 Cable/Port Problems: Try Another USB-cable (preferably original) or port USB 2.0.
- 🖥️ No drivers: install Mi PC Suite or drivers manually through Device Manager.
- 🔄 Phone is not in Fastboot mode: reboot your device in Fastboot.
Mistake 3: FAILED (remote: 'Flashing is not allowed in Lock State')
Reason: Trying to flash a partition (e.g., recovery) on a locked bootloader.
Solution: Unlock the bootloader via Mi Unlock Tool or use the official firmware with the Clean all and lock option in MiFlash.
Error 4: Cyclical reboot after firmware
Reasons:
- Anti-Rollback version incompatible (relevant for Redmi Note) 10/11, Xiaomi 12/13).
- Damage to the boot or dtbo section.
- Absence of file persist.img in firmware (important for models with Qualcomm).
Solution: Sweep through the full official firmware with the Clean all option in MiFlash. If it doesn't work, you need to switch to the new firmware. EDL Mode.
💡
Always check the compatibility of the Anti-Rollback version before firmware! For example, the Redmi Note 10 Pro (sweet) has the minimum supported version — V12.5.2.0. If you sew an older one, the phone will turn into a brick".
Fastboot vs EDL Mode: When you need emergency mode
If Fastboot doesn’t help you recover your phone (for example, after a failed firmware or hardware failure), help comes. EDL Mode (Emergency Download Mode) is a low-level mode that allows you to flash the device directly through the diagnostic port, bypassing the bootloader.
When you need an EDL:
- 🚨 Phone is not defined in Fastboot (fastboot devices returns blank list).
- 🔧 Bootloader damaged after failed unlock.
- 📉 The device does not turn on even after charging (symptoms: vibration when connected to the RAM, but the screen is black).
- 🔄 Need to be stitched persist.img or modemst1/st2 (for example, to restore IMEI).
How to log into EDL:
On most Xiaomi models to enter the EDL required:
- Turn off the phone.
- Close the test point on the board (location depends on the model, for example, on the Redmi Note 9 Pro these are contacts near the USB-port).
- Connect USB-cable to PC – the device is defined as Qualcomm HS-USB QDLoader 9008.
For firmware in EDL Use utilities like MiFlash (with optional features) EDL), QFil or UFED. But there are nuances:
- 🔐 Auto file required for new models (e.g. Xiaomi 12 and newer).
- ⚠️ Risk of damaging eMMCs if the firmware is incorrect (for example, if you choose an incorrect programmer).
- 💰 In some models (for example, POCO F4) unlockable EDL You need a paid loan in services like DC-Phoenix.
If you are not sure about your skills, it is better to contact a service center - work with the help of the EDL Requires experience and knowledge of circuitry.
