When you pick up your Redmi Note 7 and find that access to it is limited, you can be taken by surprise at the most inopportune moment. PIN-Device owners often encounter a lock screen after resetting settings or buying a gadget from their hands without knowing the previous history of its use.
There are several layers of protection built into the MIUI shell and Android operating system. Understanding exactly what type of lock is activated on your device is the first and most important step to regaining access. In this article, we will take a detailed look at all possible scenarios, from simply resetting your screen password to complex unlocking the bootloader so you can take back control of your device.
It is important to note at once that the methods of solving the problem directly depend on whether debugging was included on the USB until the lockdown and whether access to the tied SIM-We will look at both official and alternative recovery options, but remember that tampering with system files always carries certain risks.
Types of locks in Xiaomi smartphones
Before you start taking action, you need to clearly identify the type of lock you've encountered. There can be three main types of locks on the Redmi Note 7, and each requires a different approach. Definition confusion often leads to unnecessary action and time wasted.
The first and most common type is a lock screen, which is a pattern lock, a digital key. PIN-code, password or biometric data (fingerprint, Face) ID). If you forget this code, the system will not let you enter the menu, but the data inside the phone can remain intact if you manage to log in through the account.
The second type is FRP, which is reset protection, which is activated if you have done a full Hard Reset button without deleting your Google account, in which case the phone will require you to enter a login and password from the Google account that was synced to the device before the reset.
β οΈ Warning: Trying to guess a password or pattern lock multiple times in a row will cause the device to be temporarily locked for 30 seconds, 1 minute, or even 12 hours.
The third, most serious, level is Bootloader locking, and if you turn on your phone and you see a lock that says "Locked," it means that the bootloader is closed, and it doesn't give you permission to change your system files, install custom firmware, or get Root rights. Unlocking the bootloader is a separate process that requires official permission from the company.

- π‘οΈ FRP (Google Lock: Protection against theft after resetting.
- βοΈ Mi Account Lock: Linking the device to the cloud service Xiaomi.
- π Bootloader Lock: Protection of the system partition from modifications.
Determining the exact type of problem will save you hours of searching for the wrong solutions, and if the phone just asks for the screen password, that's one situation, but if it requires an account after flashing it over, it's FRP or Mi Cloud Lock, and the methods will be very different.
Resetting the screen password via Mi Cloud
If your Redmi Note 7 has the internet enabled and you have signed in to your Mi Account, you have a great way to unlock your device remotely, and this only works if Find Device has been activated in advance, and it's a regular and secure way that doesn't require a computer connection.
To start, you need to go to the official website of the Xiaomi cloud service from any other device, whether it is a computer or another smartphone. Enter your credentials (login and password) that were used on the locked phone.
Once you select Redmi Note 7, you'll have options available in the control menu, and we're interested in "Device Lock" feature, and by clicking on it, you can set a new 6-digit temporary password, which will replace your forgotten graphical key or pin on your phone screen.

If Find Device is not activated, this method will not work, in which case you will have to resort to a complete reset via Recovery Mode.
It's important to understand that this method doesn't restore a forgotten password, it replaces it with a new one. Once you enter a new code on your phone screen, you'll access the menu, and immediately after that, it's highly recommended that you go to the security settings and disable the lock or set a new, memorable password.
- π Go to i.mi.com.
- π² Select your Redmi Note 7 from the Device List.
- π’ Click "Block" and set a new 6-digit code.
- β Enter a new code on the smartphone screen.
This is especially true if the phone is locked away from home, and only a computer with the Internet is on hand. The speed of the operation depends on the quality of the connection on the smartphone itself. If the phone was in air mode, the command will be executed as soon as it appears on the network.
Hard Reset: Complete Reset with Recovery Mode
When remote methods are unavailable and the screen password is completely forgotten, the only way out is to completely reset the settings to the factory settings, which completely clears the phone's internal memory by deleting all photos, contacts and applications, but returns access to the system. For the Redmi Note 7, this process is standard and is performed through the Recovery menu.
To get into the recovery menu, you need to turn off your smartphone completely. Then press the Volume Up button (Vol +) 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 keep the volume. In a few seconds, a menu with a black background and orange-blue inscriptions will appear.
βοΈ Preparation for Hard Reset
In the Recovery menu, the volume buttons (up/down) are used to control the selection, and the power button confirms the choice. You need to select a language (usually English), then go to Wipe Data, and the system will warn you about the loss of data several more times - confirm the action.
β οΈ After Hard Reset on Redmi Note 7 will work protection FRP. You will need a login and password from a Google account that was synced to your phone before the reset.
The reset process takes 10 to 30 seconds. Once it's done, the phone will automatically restart. The first turn on after the reset will last longer than usual, as the system is first configuring the file structures. Be patient and don't interrupt the process.
If you donβt remember the data from your Google account, things get complicated: Youβll either have to restore access to your account via a browser on another device, or look for ways to bypass FRP, which often varies depending on the Android version and security patch.
FRP and Mi Account Protection
FRP (Factory Reset Protection) protection and Mi Account binding are designed to render a stolen phone useless after a reset, but legal owners often find themselves locked outside their equipment because of forgotten passwords, and bypassing these protections is a complex technical procedure.
There are specific vulnerabilities for devices based on the Snapdragon 660 processor installed in the Redmi Note 7. One popular method involves using a special cable (Test Point) to switch to EDL (Emergency Download Mode) and firmware with cleaned partitions of protection, which requires a computer and skills to work with a soldering iron or disassemble the case.
A softer method is to exploit vulnerabilities in the browser or Android settings during the initial setup, such as connecting to Wi-Fi, calling the special features menu via a voice assistant, or using keyboard settings to access the browser. Through the browser you can download the necessary APK-binding-file.
| Method | Equipment required | Difficulty | Risk of loss of guarantee |
|---|---|---|---|
| Test Point (EDL) | PC, cable, soldering iron/clip | Tall. | Yes. |
| Browser-based detour | Only Smartphone and Wi-Fi | Medium | No. |
| Service software | PC, Licensed Service Account | Low. | Yes. |
| Official service | Checks, box, documents. | Low. | No. |
There are paid service programs, such as the Mi Unlock Tool (official, but waits 168 hours) or third-party utilities like Chimera or Octoplus. They allow you to unblock Mi Account, but often require the purchase of a license or tokens. Using unofficial software always carries the risk of turning the phone into a brick.
What is an EDL mode?
Unlocking the bootloader (Bootloader)
Many users want to unlock the bootloader on the Redmi Note 7 to install custom firmware (like Pixel Experience or LineageOS) or gain root rights. The official unlock method is simple but takes time. You'll need the Mi Unlock Tool utility on your PC and a phone-linked Mi Account.
First, turn on the developer mode in your phone settings, and then you need to quickly click 7 times on the build number in the About menu, then activate OEM Unlocking and USB Debugging in the advanced settings.
Once you have an account, the system will put you in a waiting line, which is usually 168 hours (7 days), during which time you can not log out and change your account. SIM-After the expiration of the term, you need to connect the phone in Fastboot mode (clamp Vol and Power) and start unlocking through the program on the PC.
β οΈ Warning: Unlocking the bootloader automatically performs a full Wipe All Data reset. All your files will be deleted without the possibility of recovery. It can also reduce the security of the device and make it impossible to use certain banking applications without additional manipulation.
It takes a few minutes to unlock, and the phone will reboot, and you'll see an image of the open lock on the boot screen, which signals that the device is now open for modifications, and if you decide to return it as it was, you can lock the bootloader back, but that's only possible on stock firmware.
- π§ Download Mi Unlock Tool from the official website.
- π Link your account in the settings for developers.
- β³ Wait 168 hours (7 days).
- π Unlock it through Fastboot.
It is worth noting that the unlocked bootloader makes the device more vulnerable to malware, as check the integrity of system partitions disappears at start.
