The situation when the owner of Xiaomi Redmi 9 forgets the password, PIN-A smartphone can lock up after a reboot or system update, requiring proof of identity that you can't remember, which causes panic, especially if the device holds important contacts or photos.
But don’t despair, as the Android operating system and MIUI shell provide several standard ways to restore access, and in this article we will discuss in detail the methods of unlocking, from using a Google account to a complete reset through the engineering menu.
It should be warned that most of the protection methods of modern Xiaomi smartphones are built on the security of user data, so in many cases, to regain access to the phone, you will have to sacrifice files stored in internal memory.
Using a Google Account to Reset
The first and easiest way is to log in to Google’s account on a blocked Redmi 9, geolocation enabled, and active internet access, which allows you to unlock your device without losing data, but it doesn’t work on all Android versions and requires you to pre-set the Find Device feature.
You'll need a computer or other smartphone, go to the official Google Find My Device website and log in with the same account that's used on the locked phone, and it will automatically determine the location of your Xiaomi.
Once you select the device, the control panel will appear on the left menu, and you will select the "Erase Device" option, which will remove the lock password, but also erase all data, and if the unlock function is available in your region and version of the software, the system will only suggest resetting the password.
- 🔑 Make sure that the locked phone is connected to Wi-Fi or mobile network.
- 🌐 The account must be logged in in advance, before blocking.
- ⚙️ The “Find Device” function must be activated in the security settings.
⚠️ Warning: If the phone is in flight mode or off, the reset command will only be executed after it is connected to the network.
Unlocking with Mi Account
Xiaomi smartphone owners often create a Mi Account for cloud services and sync. If you have linked your Redmi 9 to your Mi Account and enabled Find a Device, you can unlock the screen through the official MIUI website.
To do this, go to i.mi.com from any available gadget, enter the username and password from your Mi Account. In the interface, select the Find Device section, and the map will display the location of your smartphone.
From the device management menu, select Unlock, which can request confirmation via SMS to a linked number or an additional security code, which is good because it sometimes only resets the lock screen while saving files.
It’s worth noting that once unlocked, the phone may require you to enter a password from your Mi Account the next time you download it, which is an Activation Lock security mechanism that prevents the stolen devices from being used.
Resetting with Recovery Mode (Hard Reset)
If online methods fail or the phone is not connected to the Internet, the only reliable option is Hard Reset, which completely clears the internal memory of the smartphone, returning it to a factory state.
Before starting the procedure, make sure that the battery charge is at least 30-40%. interruption of the firmware or reset process due to battery discharge can damage system files and the inability to turn on the phone.
To enter recovery mode on Redmi 9, you need to perform a certain sequence of actions with the buttons. Turn off the smartphone completely. Then press the volume button and the power button simultaneously.
Volume Up + Nutrition (hold until the logo appears)When the Redmi or Mi logo appears on the screen, release the power button, but keep holding the volume button until the main Recovery menu appears. The control in this menu is done with volume buttons (up-down), and the choice of item is made by the power button.
☑️ Ready for Hard Reset
From the Recovery menu, select English (if available), then go to Wipe Data. Then select Wipe All Data and confirm the action by selecting Confirm. The process will take a few minutes, after which the phone will restart.
⚠️ Warning: Once reset, the phone will require you to enter a Google account that was synced to the device earlier (FRP).
Comparison of Unlocking Methods
To make it easier for you to choose the right option, let’s compare the methods described by key parameters, each of which has its advantages and disadvantages depending on your particular situation.
| Method | Data retention | We need the Internet. | Difficulty |
|---|---|---|---|
| Google Find My Device | No (usually) | Yes. | Low. |
| Mi Account | Maybe. | Yes. | Low. |
| Recovery Mode (Hard Reset) | No. | No. | Medium |
| Smart Assistant (Mi PC Suite) | No. | Yes (on PC) | Tall. |
As you can see from the table, complete data retention without knowing the password on modern versions of Android is almost impossible for security reasons.
Use of third-party PC software such as Mi PC suite ADB-commands, often require pre-inclusive debugging USB. If you didn’t activate this feature in the Developer Menu before blocking, these methods will be useless.
Protection against FRP reset (Google Lock)
Once you've done Hard Reset, you'll come across a screen that's set up in the initial settings, and when you're connected to Wi-Fi, Google's security system will check if the phone has been illegally dropped, a phenomenon called FRP (Factory Reset Protection).
The phone will require you to enter a login and password from a Google account that was synced to the device before the reset, so that the attacker who found or stole the phone can’t just reset it and use it as his own.
If you remember your account, just enter the data. If you forget both your phone password and your Google email password, it will be difficult to restore access, and you will have to use the procedure to restore your Google account through a browser on another device.
What to do if you forget your Google account?
Don't try to guess the password many times. After a few failed attempts, the system will temporarily block the input, and then may require a 24-hour wait. In some cases, the device may be completely locked.
Preventing blocking in the future
To avoid such situations in the future, experts recommend configuring alternative ways to unlock. The Xiaomi Redmi 9 has a fingerprint scanner and facial unlock that can be used instead of entering a complex password every time.
Go to security settings and add a fingerprint. Also set up Smart Lock, which lets you keep your phone unlocked in secure places (like your home) or when you connect to a trusted Bluetooth device, like a smartwatch or headphones.
💡
Write down yours. PIN-A code or pattern lock to a secure place (notebook, password manager) that is not in the phone itself.
Back up your important data regularly, use Google Photos cloud services for images and sync your contacts with your Google account, so even if you reset completely, you won’t lose important information.
