When you pick up your Xiaomi Redmi 9 and see a lock message, it can throw anyone out of the loop, and the screen can report a link to someone else's account, require a password you don't remember, or the device can be completely locked by the carrier, and depending on the type of lock, the ways to solve the problem are radically different.
First of all, you need to clearly define what kind of restriction you are facing. MIUI), Screen protection (pattern lock, PIN-code, bootloader lock, or cell phone restriction, misdiagnosing will lead to lost time and data, so carefully read the text on the screen.
In this article, we will take a look at all possible scenarios for a Redmi 9 smartphone lock and provide step-by-step instructions for restoring access, and we will touch on both software reset methods and hardware features that are often silent in service centers.
Identification of the type of lock on Redmi 9
The first step is to determine exactly what the denial is, and if the Mi logo is displayed on the screen, requiring you to enter your account password after resetting, it's about protecting Find Device, the most common case where the previous owner hasn't untied the device.
If the smartphone requires a pattern lock or a digital code immediately after activation, but does not mention the Xiaomi account, then the problem lies in local screen protection, in which case the Android security system prevents unauthorized access to user data.
⚠️ Warning: If the device reports that it is blocked by the operator (e.g,"SIM network unlock PIN"), So software methods to reset the firmware won't help. You need to have a special unlock code that's only issued by the operator.
There is also a fastboot lock, which is manifested when you try to flash the lock icon that says "Locked," which is a standard protection against installing modified software, and it requires a formal procedure through the company's servers to remove it.
Removing the screen lock and pattern lock
If you forget your screen unlock password but have access to a Google or Mi Account, the recovery process will go relatively smoothly.In modern versions of the Android 10/11 MIUI shell, direct deletion of the password file through Recovery without data loss has become difficult for security reasons.
The most reliable way is to use Google’s Find Device feature, which requires that the smartphone is turned on, connected to the Internet (Wi-Fi or mobile network) and has a Google account activated on it. Go to android.com/find from any other device and select a lock or reset command.
An alternative method through Xiaomi works similarly: Go to i.mi.com, log in to your account and select "Find Device." If your phone is online, you can remotely set a new password or perform a full reset.
- 🔑 Use Google Find My Device to Reset Your Screen Password Remotely.
- 📱 i.mi.com allows you to manage the lock through your Xiaomi account.
- 🔄 Completely clearing your data through Recovery (Hard Reset) will delete the key, but require account confirmation.
- ⏳ After 5-10 Failed attempts to enter the system temporarily blocks the input to the 30 seconds or more.
It’s important to understand that once you force Hard Reset through the Recovery menu, the system will require you to enter your Google or Mi Account details, which were previously synced, a theft protection known as FRP (Factory Reset Protection).
☑️ Checklist before resetting password
Unlocking Mi Account and Protecting Find Device
Blocking a MIUI account is a major obstacle that occurs if you bought a used phone and the seller didn’t log out of your profile, or if you forgot the data yourself. The screen will say, “This device is locked to Mi Account...” Without removing this anchorage, the phone becomes a “brick” with limited functionality.
The only legal and safe way to unlock is to contact the previous owner, who has to go to i.mi.com, remove the device from his list and reset at his end, only then the lock will fall off when he connects to the network.
If you are the legal owner but have forgotten your password, use the recovery form at mi.com. you will need access to the linked phone number or mailbox. the process can take anywhere from a few minutes to several days, depending on the proof of ownership provided (checks, box).
⚠️ Note: Using third-party services to bypass Mi Account is often temporary, after restarting or updating the firmware, the lock is returned.
There is also an official procedure for unlocking through Xiaomi support, if you have a box and a check, you send photos of documents, and if the service decides positively, the service can unlock the device remotely or provide instructions.
| Unlocking method | Conditions required | Risk of data loss | Official status |
|---|---|---|---|
| Password recovery | Access to email/phone | No. | Fully officially |
| Appeal to the owner | Seller's contact | No. | Recommended |
| Service centre | Check, box, documents. | Yeah (often) | Officially. |
| Third-party software (Bypass) | PC, Skills, Risk of Viruses | High-pitched | Informal/Risky |
What is activation locking?
Hard Reset: Complete Reset with Recovery Mode
If the software methods don’t help or accounts are not available, there is still the option of a full reset via Recovery Mode. On Redmi 9, this process requires an accurate hit to the Recovery menu., this action will delete all photos, contacts and apps.
To enter Recovery mode, you need to turn off your smartphone completely. Then press the Volume Up and Power button at the same time. Hold them until the Mi logo appears, then release power, continuing to keep the volume.

💡
Hard Reset solves the problem of forgotten screen password, but does not remove the binding to the accounts of cloud services, if they were active before the reset.
Unlocking the bootloader on Xiaomi
Many users confuse locking the screen with locking the bootloader, saying "Locked" in orange or blue when you turn on the phone indicates that the bootloader is closed, and this does not allow you to install custom Recovery (TWRP) or-modified firmware.
Unlocking requires the official Mi Unlock Tool on PC. The process is not instant: after submitting an application in the application "Mi Unlock Status" on the phone you will have to wait from 7 to 168 hours. Xiaomi artificially delays the process for security.
The procedure is as follows:
1. Enable Developer Mode (7 times click on the MIUI version in the settings).
2. In the "Developers" menu, activate OEM Unlock and USB Debugging.
3. Link your account in the "Mi Unlock status" item.
4. boot into Fastboot (clamping Volume Down + Power) and connect to the PC.
⚠️ Attention: Unlocking the bootloader automatically performs a full data reset (Wipe Data), which can also lead to a decrease in photo quality (noise processing) and the breakdown of some banking applications due to a violation of the integrity of the system.
Don't try to unlock the bootloader on someone else's account. Mi Unlock will check if the account on the phone matches the one used in the program on the computer. If the accounts are different, unlocking is impossible.
Frequent problems and their solution
Even following the instructions, Redmi 9 users may encounter unforeseen difficulties, such as the phone may freeze on the logo after resetting, in which case try holding the power button for more than 15 seconds to force a reboot.
If the computer doesn’t see the phone in Fastboot mode to unlock, the problem may be in the drivers or the driver. USB-Use the original cable and port. USB 2.0. Installation of drivers ADB/Fastboot often solves the problem of recognition.
If the phone is locked by the operator and requests a network unlock code, don't enter random combinations. After 10 wrong attempts, the code is not available. PUK block SIM-You should contact the operator's office with your passport.
- 🔌 The problem with drivers is solved by installing Mi PC Suite or universal Google drivers.
- 🔋 When hanging in the reset process, make sure the battery is at least 50%.
- 🌐 Network error when unlocking Mi Account is often solved by changing DNS at 8.8.8.8 in Wi-Fi settings.
- 📱 If the sensor is not responsive in Recovery, try connecting. USB-mouse-wise OTG-cable.
Remember that hardware locks (such as damage to the board or memory) are not solved by software methods. If the phone does not respond to on at all, it may need repair in the service center.
Why does the phone need an old account after a reset?
Preventing blocking in the future
To avoid such situations in the future, it is important to maintain digital hygiene. Always untie accounts before selling or transferring a device. To do this, go to Settings -> Accounts and sync and delete all associated profiles before resetting.
Write passwords to a secure location or use password managers. Forgotten screen pins are one of the most common reasons for accessing the service. Regularly back up data in the Mi Cloud or Google Drive cloud.
Don't buy phones with your hands without checking for locks. Turn on your phone, connect your Wi-Fi and make sure it doesn't require someone else's password. Checking IMEI through official databases will also help you know if the device is being stolen.
