The Xiaomi Mi8, released in 2018, is still a popular device due to its balance between performance and price. However, owners often face the need to unlock: whether it is a forgotten pattern lock, a desire to install custom firmware or locking a Mi Account. The process of restoring access can range from simply resetting settings to difficult work with the bootloader.
In this article, we will take a closer look at all the possible locking scenarios you may encounter. It is important to understand that unlocking the bootloader and resetting the screen password are fundamentally different procedures that require distinct tools and approaches. We will look at the official methods, as well as the technical nuances that are not discussed in service centers.
Before you start to act, you need to assess the current state of the device. If the phone turns on and reacts to touch, the range of possibilities is wide. If the screen is out or the system is suspended in a cyclical reboot, you need methods of forced intervention through Fastboot or Recovery. Successful unlocking the bootloader depends on the wait time after you submit your application to MIUI.
Preparation of device and tools
Any manipulation of the system partition requires careful preparation. Ignoring this stage often leads to the device becoming a brick or getting into a bootloop state. You will need a computer running Windows, since most of the utilities from Xiaomi, including Mi Unlock, work incorrectly or do not work at all on macOS and Linux without emulators.
First thing you need to do is activate the developer mode. → On the phone and press quickly 7-10 once in the field "Version" MIUI". After the notification “You became a developer” appears, go back to the main settings menu, find the option → For developers, you need to turn on the debugging option here. USB.
This is followed by a critical step that is often overlooked: In the same developer menu, find the item "Mi Unlock Status" (or "Unlock Mi"), click on it, agree to the warnings, and link your account to your device. The system will require a Wi-Fi or mobile connection. Make sure that SIM-The card is installed and active, since the binding is on it.
⚠️ Note: Once an account is linked to a bootloader, Xiaomi imposes a time limit.The standard waiting period is 168 hours (7 days.
You will also need to download and install drivers. ADB And Fastboot, without them, the computer can't communicate properly with the phone in firmware mode. USB-cable, as cheap analogues often do not withstand long data transfer and can cause a connection break at a critical moment.
Official unlocking of the bootloader via Mi Unlock
Unlocking the bootloader is the only legal way to gain full access to the Xiaomi Mi8 file system, which is required to install customized recaps (TWRPs), obtain superuser rights (Root) or change the firmware region.
To start, download the official Mi Unlock Tool from the developer's website. Unpack the archive and launch the file. miflash_unlock.exe Sign in to your Mi Account, the same one that was previously linked to your phone, and the utility will automatically check the anchor status and remaining waiting time.
When the wait period expires, turn the smartphone into Fastboot mode. To do this, turn the device off completely, and then press the Volume Down and Power buttons simultaneously. Hold them until an image with a hare repairing an android appears. Connect the phone with a cable to a PC.
☑️ Checking before unlocking
In Mi Unlock, click Unlock, a warning will appear that all data will be deleted, confirm the action, and the process will take a few seconds, after which the phone will automatically restart and begin to clean the data. If you see an error message, don’t panic – reconnecting the cable or changing it often helps. USB-port.
⚠️ Warning: Unlocking the bootloader irreversibly erases all user data. Pre-save photos, contacts and documents to the cloud or computer.
Once successfully unlocked, the screensaver will display an open lock icon, which is a routine behavior that indicates that the integrity protection of the system is weakened to make changes.
Resetting a forgotten password or pattern lock
If the problem is a forgotten screen password and you can’t access the system, the only way out is to completely reset through Recovery Mode.This method doesn’t require an unlocked bootloader, but will result in the loss of all the data stored in the internal memory.
To get into the recovery menu, turn off your smartphone. Press the Volume Up button and Power at the same time. Hold them until the Mi logo appears, then release the power button, while still holding the volume. In a few seconds, the main MIUI Recovery menu will open.
Navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to select Wipe Data. In the next screen, select Wipe All Data and confirm the action. The system will ask for consent several times - this is protection against accidental pressing.
Once the cleaning process is complete, select Reboot -> Reboot to System. The phone will start as new. The first download will require you to enter the password from the Google and Mi accounts that were synced earlier. This is an Anti-theft security measure.
In some cases, if the phone was not turned on the Internet or entered Google account, the system may miss the verification stage, but on modern versions of MIUI, it is almost impossible to bypass Google account verification (FRP) without specialized tools.
Delete the Mi Account (Mi Account Lock)
The situation with the locking of the Mi Account (Find Device) is one of the most difficult: if you bought a used phone and it was blocked by the previous owner, or you forgot the login details, the device turns into a useless piece of plastic, officially unlock it only with the username and password.
If you are the legitimate owner but don't remember the data, contact Xiaomi's customer service with a check to buy. They can help reset the peg remotely. If that's not possible, there are technical ways to bypass, but they require an unlocked bootloader and custom recap.
The bypass procedure usually looks like this: after resetting the data and the activation screen appears, connect to Wi-Fi. APK-files (downloaded via browser), you need to activate ADB Or access the settings. But on Xiaomi. Mi8 With the latest Android security updates 10/11 Many vulnerabilities are closed.
| Method | Conditions required | Risk of data loss | Difficulty |
|---|---|---|---|
| Official discharge | Access to the account | No. | Low. |
| Hard Reset | Physical access | Yes (100%) | Low. |
| Bypass (circumvention) | Unlocked BL | Yes. | Tall. |
| Service centre | Phone IDs. | Depends on the method. | Medium |
It is important to understand that any methods of unlocking someone else's phone are illegal, and the instructions are intended solely to restore access to your own devices, and if the phone is found or bought with a lock, it is fair to try to contact the previous owner.
Fastboot Mode and Firmware via Mi Flash
If software failures have caused the phone to not boot, flashing will help.Fastboot mode on Xiaomi Mi8 allows you to record system images directly, bypassing the OS bootloader. This will require a firmware file in.tgz format (for Fastboot), not.zip (for Recovery).
Download the current firmware for your model (codename dipper for the model) Mi8) Unpack the archive in the root of the C disk so that the path is short, for example, C:\ROM\. Long Cyrillic tracks often cause errors in Mi Flash Tool.
Launch the Mi Flash Tool, press the Refresh button after connecting your phone in Fastboot mode. Make sure the device is determined. In the lower right corner, select firmware mode. For a clean installation, choose clean all - this will completely delete the data and unlock the bootloader (if it is already unlocked).
What to do if Mi Flash is making an error?
Press Flash and wait until the process is over. A green bar that says "success" stands for success. The phone will reboot itself. The first run can take up to 10-15 minutes, don't interrupt it.
⚠️ Warning: Clean all and lock mode will lock the bootloader back. If you flash global firmware to the Chinese version (or vice versa) with the bootloader closed, the phone will go into eternal restart (bootloop).
Recovery after a failed unlock
Sometimes the process is interrupted by a power surge, a bad cable or a driver failure. If the screen is out and the phone is not responding to buttons, it may be in EDL (Emergency Download Mode) mode. In this case, the screen is black, but in Windows Device Manager, in the Ports section, a Qualcomm HS-USB QDLoader 9008 device will appear.
To get out of this state on Xiaomi Mi8 often helps to press the power button for 15-20 seconds. If it does not help, you will need to disassemble the case and close the test points on the board (Test Point) to force you to enter the 9008 mode and flash the phone through an engineering cable.
If the phone is turned on but cyclically restarted (bootloop), try entering Recovery mode and doing Wipe Data. If that doesn't work, only a complete flashing through Fastboot, as described in the previous section, will help. Don't be afraid to experiment with the software part, since the hardware of the Xiaomi Mi8 is quite difficult to damage software if there was no physical intervention in the soldering process.
💡
Use it. USB-It's a self-powered hub that ensures that the power surges in the PC motherboard port don't interrupt the critical data writing process.
Remember that every failed firmware attempt increases the risk, but in most cases, software errors are reversible, and the main thing is to stay calm and follow the algorithms clearly.
