Xiaomi smartphone owners often face a situation where access to the device is limited due to a forgotten password or pattern lock.The Redmi Note 4 model, despite its age, remains popular due to its robust hardware, but it is the older versions of MIUI that have specific protection algorithms. Understanding exactly how the security system works in your particular case is the first step to regaining access.
There are several scenarios of blocking: from simple forgotten PIN-In this article, we will discuss all possible options for circumventing protection, using both regular system tools and specialized tools for advanced users.
It is important to note that the methods of unlocking can vary depending on the version of the installed firmware (Global, China, Stable, Developer). Some methods involve the complete deletion of user data, so it is worthwhile to carefully read each item before starting active actions.
Determination of the type of lock and preparation
Before you start active actions, you need to clearly identify what exactly is blocking the login. The lock screen can request a graphical pattern, digital code or password from your Google and Mi Account. If the device requires you to enter a password from your Mi Account after you try to reset, this means that the “Find device” function has been activated.
Preparing for the unlock procedure involves several critical steps: First, make sure the battery is at least 50-60%, and interrupting the firmware or reset process due to battery discharge can lead to irreversible consequences for the software part.
⚠️ Warning: If your phone has important data that has not been synced to the cloud, most unlocking methods will result in its total loss.
You will also need quality. USB-cable, preferably original or certified, as cheap cables often only work for charging and do not transmit data. ADB and Fastboot, or specialized software, which will be discussed below.
- 🔋 Charge the device to at least 60% for stable operation during the procedure.
- 💻 Prepare a computer with Windows and free USB-Port (it is better to use the port) USB 2.0 at the rear of the system unit).
- 🔌 Find a good one. USB-A cable that can transmit data, not just charge.
- 📝 Write it down. IMI-Device code (located on the box or under the battery), it may be needed to detach from the account.
If you plan to use methods associated with flashing, download the current version of the firmware for your model in advance. For Redmi Note 4 (codenamed nickel for the global version or mido for the Chinese version), it is important not to confuse the files, as installing incompatible software can “brick” the gadget.
Reset via Recovery (Hard Reset)
The most common and affordable method of unlocking is to perform a full reset via the Recovery menu, which is effective if you forgot the pattern lock, but the device did not activate the Mi Cloud protection or remember the data from the account for subsequent authorization.
To enter recovery mode, you need to turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power button, continuing to hold the volume until the main menu appears.
☑️ Recovery login algorithm
In the Recovery menu, the navigation 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. Next, the system can suggest choosing Wipe All Data to completely delete user information.
The reset process takes between seconds and a couple of minutes, and when it's complete, the system will automatically restart. The first run will take longer than usual, as the initial Android setup takes place.
⚠️ Attention: On new versions MIUI After resetting via Recovery, the system may require you to enter a password from the Wi-Fi network the phone previously connected to, or a password from Mi-acca.
If after a reboot, the phone asks you to enter a password from a Mi Account you don’t remember, this method won’t help you finally unlock the device without your account data, which will require a more complicated procedure through Fastboot.
Unlocking through Fastboot and Mi Unlock
If a standard reset doesn't work or the device is locked by the account, Fastboot mode is used, which is a low-level protocol that allows you to interact with the phone bootloader, and you will need the official Mi Unlock Tool utility to work with it.
To log into the Fastboot on the Redmi Note 4 turned off, press the volume and power buttons simultaneously. The screen will show an image of a rabbit repairing an android and the inscription FASTBOOT. Connect the phone to your computer with a cable.
Run the Mi Unlock Tool on your PC and log in to your Mi Account. The program must identify the device. If the bootloader is unlocked, you can reset. However, most often the bootloader is locked and the program will require (waiting) for 168 hours (7 days) after the account is linked to the device.
Why do you have to wait 168 hours?
It's important to understand the difference between unlocking the bootloader and unblocking the password. Unblocking the bootloader allows you to install custom firmware and do a full reset that ignores some protections, but it also triggers a waiting timer.
- 🔓 Unlocking the bootloader erases all data from the device automatically.
- ⏳ The wait timer at 168 hours counts from the moment of binding akka! in the developer settings.
- 🌐 Mi Unlock Tool requires a stable Internet connection on PC.
- 📱 Redmi Note 4 has different CPU versions (Snapdragon 625), make sure drivers are installed correctly.
After successfully unlocking the bootloader, you can flash clean firmware, which is guaranteed to remove the screen lock, but will require an up-to-date firmware file and care when choosing a version.
Use of Mi Cloud (Find Device)
The most civilized way to unlock the Xiaomi Redmi Note 4 without data loss (in some cases) or with minimal risk is to use the manufacturer’s cloud service. This only works if the phone has been turned on the Internet and the Find Device feature is activated.
You need to access the official i.mi.com website from any other device (computer or other smartphone) and log in with the same Mi Account that was used on the locked phone.
In the service interface, select Find Device. In the list, select your Redmi Note 4 model. The system will try to contact your phone. If you have a connection, you will have a number of features available, including locking and unlocking.
💡
If the phone is offline, the command to unlock will be automatically executed as soon as the device is online. Don't turn it off if there's a chance it's catching the network.
Remote unlock is not always available and depends on the version of MIUI and security settings. Often the service offers only remote lock or data reset (Erase), which is similar to Hard Reset.
The good thing about this method is that it doesn't require cable connection or driver installation, and it takes place remotely through Xiaomi's servers, and the main condition is that the phone must log on periodically even if the screen goes out.
Comparison of Unlocking Methods
The way you choose depends on your situation: whether you have access to your account, whether the data is important, whether you have a PC at hand, and to organize the information, let's look at the main characteristics of each method in a comparative table.
| Method | Data retention | Presence of PC | I need Internet on my phone. | Difficulty |
|---|---|---|---|---|
| Hard Reset (Recovery) | No (complete removal) | Not required | Not required | Low. |
| Mi Cloud (Find Device) | Maybe (depending on version) | Required. | I'll be sure. | Low. |
| Fastboot + Mi Unlock | No (complete removal) | Required. | Required (for binding) | Tall. |
| ADB (USB debugging) | Yes (if you're lucky) | Required. | Not required | Very high. |
As you can see from the table, the easiest way is Hard Reset, but it sacrifices data. Mi Cloud is convenient if everything has been configured beforehand. Fastboot is a "heavy artillery" for cases where other methods do not work or the device is blocked by an account.
It is worth noting that the ADB (Android Debug Bridge) method is listed in the table for completeness of the picture, but it works only if the phone has been pre-enabled debugging over USB. On a locked screen, it is impossible to activate it without special hacks, so for the average user this method is often not available.
Choose a method based on the availability of your initial data (passwords) and willingness to sacrifice information inside the phone to restore access to the device itself.
What to do if your phone is blocked by Mi Account
When you reset your phone, you need to enter your Mi Account password, called Activation Lock, which is a theft protection, and if you have a password that you just forgot, you can restore it through your Xiaomi account site using your linked email or phone number.
If the phone was bought from hand and the previous owner did not untie the device, it is almost impossible to unlock it by legal means. You will have to (contact) the seller and ask him to remotely remove the device from the list of trusted in the Mi Cloud settings.
⚠️ Warning: There are paid services and "masters" offering Mi Account unlock.Be careful: they are often scammers, or they use vulnerabilities that are closed by security updates, which can lead to unstable operation of the phone.
For Redmi Note 4, there are specific tools (e.g. Xiaomi ADB/Fastboot Tools) that can be deleted in some cases, but they require an unlocked bootloader, so if the bootloader is closed and the account is not opened, the device becomes a brick in terms of usability.
Always check your account status when you buy a used device. Go to your settings, find the Mi Account section, and make sure the device is untied. Just logging out isn't enough, you need to remove it from the trusted device list.
Prevention of blocking and useful tips
To avoid getting into situations that require difficult unlocking, you should follow several digital hygiene rules: regularly sync contacts and photos with the cloud, so that in the event of a reset, you do not lose important information.
Write your passwords in a safe place. Graphic keys are forgotten surprisingly often, especially if you rarely use them or use complex patterns. Biometrics (fingerprint) is convenient, but remember that after a reboot, the phone will still require input. PIN-code.
💡
Regular data synchronization and remembering the password from the Mi Account is the best insurance against loss of access to the device.
It is also recommended to check the status of the device in Mi Cloud periodically. Make sure that the "Find Device" function is active - this will not only help to find the lost phone, but in some cases will facilitate the unlocking procedure.
Do not install firmware or system modifications from unverified sources. TWRPs and modified firmware may contain errors in the security module, leading to false locks or cyclic reboots.
