Xiaomi smartphone owners often face the need to gain advanced access rights to the system or remove a forgotten pattern lock. The Redmi Note 8, released a few years ago, is still popular, but its software has strict security restrictions. Unlocking the bootloader is a key step for installing custom firmware, obtaining root rights or deep modification of Android.
Removing the restrictions can be required in different situations, from the banal forgotten password lock screen to the desire to install a fresh version of Android, which the manufacturer no longer officially delivers. It is important to understand that unlocking the bootloader and resetting the forgotten password are two different processes, although both require caution. Wrong actions can lead to complete failure of the device, turning it into a “brick”.
In this article, we will discuss in detail the legal ways of unlocking through the official Mi Unlock tools, methods of bypassing Mi Account in the case of buying a used device with a “locked” screen, as well as the nuances of working in Fastboot mode. We will consider the current requirements for 2026 for account and waiting time, which often change in company policy.
Preparation of the smartphone and computer for the procedure
Before you start any manipulation of the system partition, you need to carefully prepare the workplace. You will need a Windows computer (versions 7, 10 or 11), which is working properly. USB-The battery charge should be at least 60%, since the interruption of the firmware process due to discharge is critical for the motherboard.
The first step is to activate the developer mode. Go to Settings for that. → On the phone and press. 7-10 once in a row in the field version MIUI. After the notification “You became a developer” appears, go back to the settings menu, select Additional → For developers, you need to find the factory unlock (OEM Unlocking) and activating it.
💡
Use the original. USB-A cable or high-quality analogue with thick wires. Cheap charging cables may not provide a stable data transfer, which will lead to a connection error during the unlocking process.
You then need to link your Mi Account to your device. In the same Developer menu, find Linking your Mi Account to your device. Click Link. The system will require you to enter your Mi Account password. Make sure the device is installed. SIM-card with active mobile Internet, as Wi-Fi binding may not work or cause server error.
☑️ Checklist of preparations
Official unlocking of the bootloader via Mi Unlock
The official method is the only safe way that does not violate the warranty (if it is still relevant) and does not require complex manipulation of soldering. This will require the Mi Unlock Tool utility, which you need to download from the official developer website. Once you install the program, launch it and log in to the same Mi Account that was associated with the phone.
Put your smartphone in Fastboot mode. Turn the device off completely, then press the Volume Down and Power buttons simultaneously. Hold them until you see an image of a hare repairing an android or the words FASTBOOT. Connect your phone to your computer with a cable. Mi Unlock should have a message about the successful connection of the device.
Click Unlock. If less than 168 hours (7 days) have passed since your account was linked, you will get an error stating the remaining latency. This is Xiaomi's standard security measure. If the deadline has expired, the process will take a few minutes: the phone will restart, all data will be deleted, and the bootloader will be free.
Why do you have to wait 7 days?
It’s worth noting that in 2026, company policies may require a higher level of trust in an account, and users may encounter a “Couldn’t verify device” error, in which case try re-linking the account: delete the current link in the developer menu and re-attach, then wait 7 days again.
Resetting a forgotten password and pattern lock
Often, the query “how to unlock” means that users can restore access to the device if they forget it. PIN-code or graphic design, in modern versions MIUI And HyperOS just resets the password through the receptacles without losing data, because of encryption, the only way to work is to reset completely).
Turn off the phone to do the reset. Press the combination of the Up and Power buttons. Hold them until the Mi logo appears, then release the power, continuing to hold the volume until the main Recovery menu opens. This is controlled by the volume buttons (up/down), and the power button selects.
Select English, then go to the Wipe Data menu. You will need to confirm the action by selecting Wipe All Data. Once you complete the process, select Reboot → Reboot to System. The phone will launch as new, but all your photos, contacts and applications will be deleted.
⚠️ Warning: Once you reset your password, the phone will require you to enter a Google account or Mi Account that was synced to the device before (FRP). If you do not remember this data, you will not be able to access the system without the use of specialized service tools.
If the device was purchased by hand and requires an account of the previous owner, it can only be legally unlocked by contacting the previous owner, otherwise it is a matter of bypassing FRP, which is a complex procedure that depends on the specific version of Android and the security patch.
Working with Mi Account and bypassing locks
The Mi Account (Find Device) lock is a major hurdle, and if a phone is tied to someone else's account, it turns into a brick when it is reset, and the only way to officially unlock that device is by submitting a purchase check to a Xiaomi authorized service center, and employees will remove the lock remotely via the server.
There is a myth that you can unlock your phone through service codes or special combinations in the dial menu. In 2026, these vulnerabilities have long been closed. Attempts to use third-party software to hack into Mi Account often lead to the installation of malware on your computer or the final lock of the device over IMEI.
However, if you are the legal owner but have forgotten the Mi-acca-unt password, use i.mi.com. Through the procedure of restoring access by phone number or backup mail, you can reset the password and untie the device from the cloud, which will allow you to unlock it after resetting.
| Type of lockdown | Symptoms. | Method of decision | Data security |
|---|---|---|---|
| Forgotten PIN/pattern lock | Requires code when enabled | Hard Reset (Recovery) | No (complete removal) |
| Mi Account (Find Device) | Requires Mi password after reset | Entering the owner's password or check in the SCC | No. |
| Bootloader (Bootloader) | Don't let you put custom software on. | Mi Unlock Tool (officially) | No (when unlocked) |
| FRP (Google Lock) | Requires Google Account After Reset | Account data entry or service bypass | No. |
Firmware via Fastboot and EDL mode
For advanced users who have not been helped by standard unlocking or need to recover from a failed firmware, there is Fastboot mode and EDL (Emergency Download) deep service mode. We mentioned Fastboot mode, which allows you to replay your phone through the Mi Flash Tool utility computer.
Regime. EDL Redmi Note 8 (codenamed ginkgo) often requires an authorized firmware account if the bootloader is locked. However, if the bootloader is already unlocked, you can flash the phone in this mode without restrictions. EDL usually requires disassembly of the phone and closing test points on the board, or the use of special commands ADB.
adb reboot edlThis command will put the phone into EDL mode if USB debugging is enabled and the phone is connected to a PC, while the screen will remain black, but the Qualcomm HS-USB QDLoader 9008 port will appear in Windows Device Manager. This is a signal that the phone is ready for low-level firmware.
💡
EDL mode is the last chance to revive a phone with a damaged software part, but on modern Xiaomi devices it often requires paid authorization of an account in the service center.
When using the Mi Flash Tool, it is important to choose the right firmware type. The Clean all option will completely clear the data and unlock the bootloader (if the server allows it). The Clean all and lock option will lock the bootloader back - use it only with global firmware for the global version of the device, otherwise you will get a brick.
Common Errors and How to Resolve Them
During the unlocking process, users often encounter error codes, one of the most common is Error 200302 (or similar codes), which means that the server cannot verify the status of the device, often solved by changing the Internet access point (for example, sharing the Internet from a phone instead of Wi-Fi), or using a VPN, since the verification servers may not be available in your region.
Another common problem is that the Mi logo freezes after unlocking (Bootloop), which occurs if the firmware for another regional version (e.g. China ROM on a Global device) has been installed with the bootloader locked, in which case only flashing through Fastboot to the stock version of the software corresponding to the region will help.
⚠️ Warning: Never interrupt the firmware process by removing the cable or turning off the computer. Interrupting the boot sector recording is guaranteed to bring the device down and recovery will require a programmer.
There is also a bug called “Current account is not the same as....” This occurs when you try to unlock your phone through an account that is different from what is tied in the developer settings on the smartphone itself. Check the email address in the Settings → Mi Account menu on your phone and in the Mi Unlock program on your PC.
If the software methods do not help, and the phone is not determined by the computer in any of the modes, perhaps the problem lies in the hardware: faulty. USB-In such cases, only a qualified repair in a service center will be able to diagnose a physical malfunction.
