It is common for a Xiaomi Redmi 9 NFC owner to be unable to access his device, such as a forgotten pattern lock, a system failure, or a Mi Account lock. It is important to understand that modern Android security systems, especially the MIUI shell, are designed to protect user data from unauthorized access.
Depending on the type of lock, the methods of removing it will be radically different. If you just forgot the screen unlock pin, the solution will be the same. If the device is blocked by a Google or Mi Account, the algorithm of actions is completely different. Full reset (Hard Reset) is the only way to remove the screen protection, but it leads to the irrevocable deletion of all user data, which is why before you start any manipulations, you need to soberly assess the situation and understand what type of lock you need to remove.
This article offers an expert approach to solving the problem. We will look at official methods, hidden features of the engineering menu and ways to bypass the protection through the computer. Don't panic if the smartphone stopped responding to usual gestures. In most cases, the Redmi 9 NFC can be brought back to life, keeping its functionality even if access to the system is completely blocked.
Diagnostics of the type of lock on Redmi 9 NFC
The first step in the process of access recovery is to pinpoint the nature of the problem, and users often confuse locking the screen with account binding, which leads to errors. If the screen displays a field for entering a pattern lock, a digital password or a fingerprint, it is about local device protection, a standard security feature that can be bypassed by resetting settings.
It is a completely different situation if after turning on the phone requires you to enter a login and password from your Google or Mi Account. This indicates the operation of the FRP (Factory Reset Protection) mechanism. This protection is activated automatically when you first log in to the account and binds the device to the owner's account.
If the system says "Device locked" and asks to contact the owner, it is possible that the smartphone is listed in the database of lost or stolen, in which case the software methods may be useless.
| Type of lockdown | Symptoms. | Data required | Difficulty |
|---|---|---|---|
| Lock screen | Requesting a pattern lock or PIN | Code or biometrics | Low (with loss of data) |
| Mi Account | Requiring Mi password after reset | Login and password Mi | Tall. |
| Google FRP | Google Account Request After Hard Reset | Email and Gmail Password | Medium/High |
| Bootloader (Bootloader) | Image of a hare with an android or the inscription Locked | Resolution from Xiaomi server | Tall. |
⚠️ Note: If you bought a used phone and faced a lock Mi Account or Google FRP, If you don't have his data, it's almost impossible to unlock the device legally.
Reset via Recovery (Hard Reset)
The most common way to unlock the Xiaomi Redmi 9 NFC when you forget your screen password is to perform Hard Reset, which returns your smartphone to factory status by removing all user files, contacts and applications, and is executed through a special recovery menu that is sewn into the device’s memory regardless of the operating system state.
To enter Recovery mode, Xiaomi models use a combination of physical buttons. First, turn off the smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then the power button can be released, while continuing to hold the volume key. In a few seconds, the main Recovery Mode menu will open.
The navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item and select it. Then the system will offer several reset options. Select Wipe All Data and confirm the action by selecting Confirm. The formatting process will take from a few seconds to a couple of minutes.
☑️ Checklist before reset
Once the procedure is complete, the phone will automatically restart. The first turn on will last longer than usual, as the system performs the initial setup. If the device did not have two-factor authorization and account binding enabled, you will get a clean, unlocked smartphone.
Remote unlocking through Xiaomi service
If your Redmi 9 NFC has the internet enabled and your Mi Account activated, you can unlock your device remotely. Xiaomi’s Find Device service not only tracks your location, but also manages your access. This method is especially useful if physical access to your smartphone buttons is difficult or faulty.
To use this method, go to the official website of the Xiaomi cloud service from any other device (computer or tablet). You will need to log in under the same Mi Account that was used on the locked phone. In the list of devices, select your Redmi 9 NFC. In the available feature menu, find the option "Block" or "Erase data".
Selecting the "Erase Data" function initiates a command to completely reset remotely. This is the analog of Hard Reset, but it is executed over the network. Once you receive the command, the phone will clear the memory and reset the screen password. However, if the device is offline, the command will be executed the first time you connect to the network.
Importantly, this method does not remove FRP protection. Once reset, the phone can still request confirmation of the owner of the Google or Mi Account when you first set up, which is a standard security behavior that cannot be avoided without entering correct data.
Bypassing FRP (Google Account)
FRP (Factory Reset Protection) blocking is a major obstacle for users who have forgotten their Google account details. On Xiaomi Redmi 9 NFC, which runs Android 10 and MIUI 12/13, this protection is implemented quite rigidly. It cannot be circumvented by standard methods, it requires specific actions or the use of a PC.
One software tool involves exploiting vulnerabilities in the system for accessing settings through the welcome screen. Often users try to activate TalkBack or use special features mode to access the browser and-settings. However, with each security update, Xiaomi closes these loopholes. For example, the method of entering a Wi-Fi password and using the Gboard keyboard to go into settings is now rare.
A more reliable but challenging method is to use a computer and debug over USB.
- ⚡ Cable USB Type-C with guaranteed data transfer.
- ⚡ Installed drivers ADB PC-only.
- ⚡ Specialized resetting software FRP (For example, Mi Unlock Tool or paid boxes).
- ⚡ Follow the instructions for a specific version of Android.
⚠️ Note: Using third-party software to bypass FRP It can be considered a threat by antivirus software. Only download tools from trusted forums and developer sites.
There's also a method of changing the region and language, which sometimes allows you to skip the checkout phase. When you first set up, you get to the Wi-Fi connection screen, try changing the language or region a few times quickly. Sometimes it causes a glitch in the interface to get to the desktop. However, on Redmi 9 NFC with the latest security patches, this trick doesn't always work.
Unlocking the bootloader (Bootloader Unlock)
Special attention should be paid to unlocking the bootloader, which is not necessary to reset the screen password, but to obtain full administrator rights (Root), install custom firmware or recavators (for example, TWRP), which is strictly regulated by the manufacturer on Xiaomi devices.
To start unlocking, you need to apply in the official Mi Unlock app on your PC. Before that, in the phone settings (Settings → About Phone → MIUI version), you need to click on the build number several times to activate the developer mode. Then in the advanced settings, the “Unlock the bootloader” option is turned on.
After submitting an application through the Mi Unlock application, you will have to wait, the wait can be from 7 to 30 days (168-720 hours), this is done so that the user can think before opening access to deep system settings, after the expiration of the program will allow you to unlock the device, but all data on it will be destroyed.
Why unlock the bootloader?
Remember that unlocked bootloader reduces the overall security of the device, in which an attacker who gains physical access to the phone can more easily read data, so after using custom functions, many users lock the bootloader back, although this requires re-flashing to the stock version.
Using PC and debugging over USB
If the phone screen is broken and does not respond to touch, USB-Debugging was enabled in advance, unlock Redmi 9 NFC You can use a computer. This is the perfect scenario, because it saves data. ADB (Android Debug Bridge).
Connect your phone to your PC and open the command line. Enter the command to output the list of connected devices: adb devices. If the device is determined, you can delete the file that stores the pattern lock. This is done using the command: adb shell rm /data/system/gesture.key (for the pattern lock) or adb shell rm /data/system/password.key.
adb shell pm clear com.android.settingsThis command will reset the lock screen settings. Once you reboot, the phone can let you in without entering a password. However, on modern versions of Android with data encryption, this method only works if the phone has already been unlocked at least once after turning on, otherwise access to the file system without a password will be closed at the kernel level.
💡
If USB-The debugging was not included in advance, methods through ADB In this case, only Hard Reset with data loss or professional repair with soldering of memory (which is not economically feasible for the Redmi 9) remains).
Restoring access to Mi Account
Often the problem of how to unblock is not a technical reset, but to restore access to the account. If the phone requires a password from Mi Account and you don't remember it, the only solution is the recovery procedure through the site. Go to i.mi.com and click Forgot password.
You will need access to the linked phone number or backup email. Xiaomi will send a confirmation code. Enter it and set a new password. Then on the locked device (if you have Internet access), you will need to update your account information in the settings. If the Internet on the phone does not work, use the Emergency Call feature to access the browser (if the firmware version allows) or connect to Wi-Fi.
In cases where the phone number is lost or the SIM card is not restored, you will have to contact Xiaomi support with a check to purchase the device, which proves that you are the legitimate owner and employees can untie the device from the account remotely.
⚠️ Warning: Never buy an "unlock" IMEI" 99% of the time, it's a scam, and you lose money, and your phone stays locked.
Preventing blocking in the future
To prevent the lock situation from happening again, it is important to properly configure the smartphone immediately after purchase. PIN-code in a secure location not associated with your phone (such as a paper notebook or password manager on your PC) and check regularly if you remember the passwords from your Google and Mi accounts.
Alternative unlocking methods are also recommended. The Redmi 9 NFC has a fingerprint scanner on the back and face unlock. Duplication of access methods will let you log in if you forget your primary password. However, remember that after you reboot the device, you still need to enter a digital code.
Regularly backing up your data in the Mi Cloud or Google Drive cloud will save you data if you need a full reset. Set up automatic synchronization of contacts, photos and notes, so even with a full memory cleanup, you can quickly recover important information on a new or reset device.
💡
The key takeaway: The best protection against lockdown is knowing your passwords and having an up-to-date backup of your data, and technical ways of bypassing are a last resort with the risk of losing information.
