Forgot the password on Redmi 9T: a full reset and unlock

When the screen of Xiaomi Redmi 9T suddenly locks and a vague memory of a complex password pops up, it can disembark anyone, most often after a system update or a long pause in use of the device, when the brain automatically substitutes old combinations. Don't panic, since the MIUI operating system provides several scenarios for restoring access, although some of them require a complete data cleanup.

The first thing to realize before you start any action is that data security is the first thing in the Android architecture, which is why resetting is a regular mechanism for protecting information from unauthorized persons. If you did not link your Mi or Google account in advance, or did not enable synchronization, restoring contacts and photos may become impossible without a backup.

In this guide, we will take a detailed look at all available unlock methods, from standard to forced, focusing on the specifics of the Redmi 9T. You will learn how to enter Restore Mode, what key combinations to use and how to avoid blocking activation after rebooting. Carefully study each step to avoid aggravating the situation.

Preparation for the procedure of unlocking the device

Before embarking on radical measures like Hard Reset, it is important to assess the current state of the gadget and the availability of alternative login options. Often users forget that they could have set up fingerprint or facial recognition logins, which can work even with forgotten digital code if the system did not require a password after rebooting.

Make sure the battery is at least 50-60% charged, as the reset and subsequent setup process can take time.If the device responds to touch, try entering the wrong password several times to see if the “Forgot Password” option or the ability to log in via Google or Mi Account appears.

⚠️ Warning: Forced resetting will result in the complete removal of all user data, including photos, contacts, messages and installed apps, if they were not synced to the cloud.

If you can, check for backups in Google Drive or Mi Cloud, and you can log in from your computer or other device via your browser, and having a fresh copy of the data will make it much easier to restore the smartphone to work after cleaning.

Reset password through Recovery (Hard Reset)

The most reliable and often the only way to get Redmi 9T back is to use the system recovery menu, which works even if the touch screen is partially non-functioning or the system is stuck in the code entry phase.

Turn off your smartphone completely. If the device doesn't respond to the power button, press the volume and power buttons simultaneously for 10-15 seconds until the screen goes out, and then immediately proceed to the next step. Press the volume button and press the power button without releasing it.

Keep both buttons clamped until the MI logo appears, and then the power button can be released while still holding the volume. When a menu with several items in English or Chinese appears on the screen, release the second button. Navigation in this menu is done with volume buttons (up and down), and selection of the item with a short press of the power button.

You need to find Wipe Data. Some firmware versions will first need to select the language (English) and then go to the cleanup section. Select the Wipe All Data option and confirm the action by selecting Confirm. The system will warn you that all data will be destroyed.

⚠️ Warning: After resetting and first downloading, the system will require you to enter a password from a Google account or Mi Account that was synced to the phone before locking (FRP).

Once confirmed, the formatting process will begin, which will take between seconds and a couple of minutes. Upon completion, the screen will show “Data wiped successfully.” Select Reboot and then Reboot to System to reboot your smartphone as normal.

Remote unlocking through Mi Cloud

If the Internet (Wi-Fi or mobile data) was turned on on the blocked Redmi 9T and the Find Device function is activated, you can try a remote reset via the official Mi Cloud service. This method is convenient because it does not require physical access to the device buttons if it is located somewhere nearby or elsewhere, but is connected to the network.

Go from your computer or other smartphone to i.mi.com, enter your Mi Account (login and password) that was used on the locked device, and if you forget your account password, use the re-access function on the same page.

In the service interface, select Find Device. The system will try to locate your Xiaomi Redmi 9T. If the device is online, you will have an action menu that includes an audible signal, lock or clear.

Select the Erase Device option. Confirm your action by re-entering your account password, and then the smartphone will automatically reset to factory settings, and the lock password will be deleted along with the rest of the data.

Google Find My Device feature

An alternative that often works even more efficiently is Google’s service, which, because the Android operating system is deeply integrated with the search giant’s services, a Google account is the key to managing the device, a method that is relevant if the phone is logged in to a Google account and geolocated.

Open your browser on any other device and go to android.com/find. Log in to the same Google account that was used on Redmi 9T. If you have multiple devices, select the one you want from the list at the top of the screen.

In the side menu, select the "Erase Device" function. The system will warn you that all data will be deleted. Press the confirmation button. The smartphone, upon receiving a signal from the server, will reset the settings and delete the pattern lock or pin code.

It is important to understand that none of the legal methods allows you to save data with a forgotten password unless you have made a preliminary backup. Android security is built on encryption of data, the key to which is your lock password.

Specifics of unlocking with FRP protection enabled

After you successfully reset your settings through Recovery or cloud services, you will encounter an initial setup screen, and this is where FRP (Factory Reset Protection) comes into effect, an anti-theft measure that requires proof of the identity of the device owner.

The system will ask you to connect to Wi-Fi and enter a password from a Google account that was synced to the phone before the reset, so if you enter another account, you won't be able to access the system, so that the attacker can't use the stolen phone after the reset.

💡

If you have changed your password from your Google account recently, use your old login password when setting up or wait 24 hours after changing your password, as the security system can block the login with the new password immediately after resetting.

In some cases, if you have recently changed your account password, the system may not accept it immediately, in which case it is recommended to wait a day or try to restore access to your account through your computer, making sure that the account information is correct.

If you don't remember your account details, the recovery process can take a long time, and you'll have to use the process of restoring access to your Google account through the site, answering security questions or using a backup email. Without this step, you won't be able to legally unlock Redmi 9T.

Alternative methods and working with ADB

For advanced users, there is a method of unlocking or resetting via USB debugging (ADB), but this method only works if you have already enabled debugging mode in the Developer Menu before blocking and authorized your computer.

If these conditions are met, connect the phone to your PC, install the Platform Tools drivers and tools. Through the command line, you can try to delete files that store access keys, or initiate adb reboot recovery, then proceed to clean up the data.

adb shell pm clear com.android.settings

This team is trying to clear the Settings app data, which in some older versions of Android allowed you to reset the password, but on modern high-security MIUI firmware, this method is often ineffective.

⚠️ Note: Using third-party bypass software FRP or a system hack can lead to an irreversible locking of the device (brick) or disruption of banking applications.

If neither method works, the problem may be hardware buttons or system files, so the only solution is to go to an authorized Xiaomi service center, where specialists can reflash the device using special equipment.

Prevention and backup

To prevent a forgotten password situation from recurring or going less painful, it's important to back up regularly. 9T There is a built-in tool “Backup and Restore” that allows you to save data on the SD-map.

Set up automatic sync of contacts, calendar and notes with your Google account. Photos and videos are best saved through the Google Photos app or Mi Cloud by enabling Autoboot, which will allow you to restore the library even after a complete reset of the device.

💡

Regularly synchronizing data with the cloud is the only way to ensure that information is safe when you lose access to your device.

It is also recommended to write complex passwords to a secure location, such as a paper notebook, or use password managers that have a master password or biometric input.

Check the health of your phone-linked accounts periodically, make sure you remember the password from Mi Account and Google, and have access to the linked phone number to obtain confirmation codes.
