Unlocking the Xiaomi bootloader with a broken phone

When your Xiaomi turns into a brick and refuses to turn on, it often becomes critical for the owner. Many users panic, believing that the device is forever lost, but this is not always the case. If the reason for the lock was a failed firmware or system failure, then unlocking the bootloader may be the only way to bring the gadget back to life.

However, the standard procedure through MIUI settings is not possible in this case, because the screen does not respond or the menu is not available. You will need to enter special diagnostic modes, such as Fastboot or EDL, and use specialized software on the computer. It is important to understand that the process requires care, since incorrect actions can lead to a complete locking of the device by the serial number.

In this guide, we will go into detail the algorithms for different lock scenarios, learn how to determine the type of brick, what tools you will need, and whether you can circumvent the restrictions without official permission from the company. Without access to Fastboot mode, official unlocking through the Mi Unlock Tool is technically impossible.

Diagnostics of the device state and determination of the type of lock

Before you start to act, you need to know exactly what your device is in. There are several stages of bricking, and it depends on how you recover. If the phone is just hanging on the Mi logo, it's a software glitch that's the easiest to fix.

A more serious problem is when the screen is black, but when connected to the computer, the connection sound is made. USB-In Windows Device Manager, this can be displayed as Qualcomm. HS-USB QDLoader 9008. This is mode. EDL (Emergency Download, which allows you to reflash the phone at a low level, bypassing the bootloader.

⚠️ Note: If the device is identified as QDLoader 9008, but you are not an authorized service center, Xiaomi servers may reject the firmware request.

It's also worth checking if the device is responding to the button combinations. Press the minus volume button and plug in the USB cable. If an image of a hare repairing an android appears on the screen, or the words FASTBOOT, you're lucky the bootloader isn't locked completely, and access to it can be tried to restore.

For a precise diagnosis, connect your phone to your PC and open Device Manager. Expand Ports (COM and LPT). Having a Qualcomm or Android device indicates that the motherboard is alive and that recovery is software-based.

Tools and workplace preparation required

90% of the success of the operation depends on proper preparation. You will need a computer with Windows operating system, as the basic tools Mi Flash Tool and Mi Unlock are unstable or do not work at all on macOS and Linux without complex emulators.

It is critical to use quality USB-Cheap charging cables often don’t have data lines, which will cause a connection error at the most inopportune time: ADB, Fastboot and Qualcomm drivers.

You need to download the firmware exclusively from official sources or trusted repositories, such as xiaomirom.com. You need a firmware version with the.tgz extension (Fastboot), not.zip (Recovery). After downloading, the archive must be unpacked into the root of the C disk so that the path to the file does not contain Cyrillic or spaces.

Remember to back up your important data if you have the slightest way to access the file system, and the process of unlocking and flashing it will completely destroy all the data on the internal storage device.

Trying to log in to Fastboot mode and working with Mi Unlock

If the phone is responding to buttons, your first goal is to get into Fastboot mode. To do this, turn the device off completely (if it is on), then press the volume button and, holding it, plug it in. USB-It's going to show an orange fox or something on the screen. FASTBOOT.

Once you enter this mode, connect your phone to your computer and start the Mi Unlock Tool. Log in to your Mi Account that may have previously been linked to your device.

If successful, the program will offer to unlock the device. However, if the phone is "brick" due to an unsuccessful attempt to unlock earlier, the server may issue an error or require a wait of 168 hours (7 days). It is not officially possible to get around this wait, but sometimes it helps to try again after 24 hours or a shift. USB-port.

If the utility gives an error "Unlock failed: Couldn't verify device", try to execute the command manually through the console. Open the command line in the folder with the ADB tools and type:

fastboot oem unlock

This command only works on some global versions and older models. For new devices with MIUI 12/13/14 and HyperOS, this method is usually ineffective without going through full authorization through the GUI.

Using EDL Mode for Deep Recovery

When the phone doesn’t respond to the buttons and the screen is black, Emergency Download (EDL) mode, also known as 9008 mode, is used to help, in which the phone’s processor goes into command standby mode, allowing the new bootloader and system to be written directly into memory.

Entering EDL on most modern Xiaomi models requires disassembling the body and closing test points on the motherboard. On some older models, a combination of volume buttons helped, but this is rare now. Points are usually signed as Test Point or indicated by gold contacts near the processor.

⚠️ Warning: Disassembling the phone and closing points can lead to loss of warranty and physical damage to the device.Do this only if you are confident in your abilities and the device is no longer subject to warranty obligations.

After entering the 9008 mode (the computer will emit a characteristic sound of connecting new hardware), launch the Mi Flash Tool. Select the previously downloaded firmware in.tgz format. In the lower right corner, select the Clean all firmware mode, but do not choose Clean all and lock, as this can permanently block the bootloader if it is not original.

Press Flash. If Xiaomi servers allow firmware, the process will go automatically. However, starting in 2019, Xiaomi has closed the 9008 firmware option for unregistered accounts, in which case the program will give an authorization error.

💡

Use the original. USB-port 2.0 on the back of the PC motherboard. USB 3.0/3.1 Sometimes cause driver conflicts when firmware old devices in mode EDL.

Bypassing restrictions and paid unlocking methods

If the official methods don't work and the servers block the request, there are workarounds, one of which is using modified versions of the Mi Unlock utility or server authentication emulating scripts, tools that often appear on forums like 4PDA or XDA, but they run the risk of viruses infecting the PC.

Another option is to contact service centers that are authorized by Xiaomi, which can unlock the bootloader remotely for a fee using their accounts, a legal but paid way that is often the only way for new HyperOS models.

There are also hardware boxes like Chimera or Octoplus that allow you to unlock at iron level, but they cost hundreds of dollars, so it's easier for the average user to pay for an unlock service from a specialist than to buy equipment.

It is important to understand the difference between Fastboot and EDL. Fastboot is a software mode that can be closed with a security update. EDL is a low-level mode that is physically protected but software-locked by a verification server.

💡

On modern Xiaomi devices, unlocking the bootloader without waiting 7 days and without a tied phone number is almost impossible by official methods.
