A situation where you pick up your Xiaomi Redmi 4 and the screen meets you with a request for a pattern lock or a graphical key. PIN-The code you can't remember is one of the most stressful for the modern user, and a mobile device today is not just a means of communication, but a repository of banking applications, work documents and personal photos. Panic at such a moment is a natural reaction, but it is cold calculation and strict adherence to the instructions that will help to return access to the gadget.
There are several proven ways to circumvent security, but their effectiveness depends on whether the pre-setting of accounts and enabled certain debugging functions. owners of Redmi 4 (including modifications Prime and Pro) are faced with a shell MIUI, which has its own security features, different from pure Android.
In this detailed guide, we will look at all the current options, from a standard reset through the recovery menu to the use of specialized software. It is important to understand that modern security systems are designed to protect your data from outsiders, so the process of unlocking the owner without a password is technically equivalent to hacking or completely resetting the device.
Using a Mi Account to reset the lock
The most civilized and safe way to restore access to Redmi 4 is to use Xiaomi’s built-in Find Device feature, which only works if the locked smartphone is logged in to Mi Account and the device is connected to the Internet (via Wi-Fi or mobile data), and if these conditions are met, you do not have to delete personal files.
First, you need to go to the official portal of cloud services of the company from a computer or another phone, the interface of the site must log in under the same login that was used on the blocked gadget, the system automatically determines the location of your Redmi 4 and will offer a list of available actions.
Among the options for managing the device, we are interested in locking or resetting. If you choose the lock option, the system will suggest setting a new password that will replace the forgotten access code. After applying the changes on the server, just wait a few minutes until the smartphone is synced with the cloud and enter a new code on the lock screen.
⚠️ Note: If the device is in flight mode or has no access to the network, the command from the server will not be received, in which case this method will not work until the Internet connection is available.
It's worth noting that Find Device requires pre-activation in your security settings, and if you've never set up Mi Cloud or enabled device search, that path will be closed, but for many prudent users, it's a way to avoid losing important contacts.
Resets via Recovery (Hard Reset) menu
If access to cloud services is not possible, the only remaining option is forced reset to factory settings, a process known as Hard Reset that completely erases the user's memory partition by removing photos, contacts, apps and, most importantly, a forgotten password. For Xiaomi Redmi 4, the procedure is performed via the Recovery menu.
To get into recovery mode, you need to turn off the smartphone completely, then you need to 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 Recovery menu with multi-touch support will appear on the screen.
In the list that appears, you need to select a language (usually English and Chinese), and then go to Wipe Data. The system will require confirmation of actions, as this is an irreversible operation. Once you select Wipe All Data and confirm it, the cleaning process will begin, which will take from 30 seconds to several minutes.
☑️ Checklist before Hard Reset
Once cleaned, the device will offer a reboot to system. The first run after a reset can last longer than usual, as the system reassembles the cache and applications.Be prepared that when turned on, the phone may request a password from a previously linked Google or Mi Account as a measure of protection against theft (FRP).
Unlocking through Google’s Find My Device service
An alternative to Xiaomi’s branded tools is the standard Google service. If your Redmi 4 has been logged in to a Google account and geolocation enabled, you can use the Android Device Manager web interest, which is similar to the Mi Account method, but works at the operating system level.
Go to the service site from any device, log in to your Google profile. If the phone is online, you'll see it on the map. In the side menu, select "Block the device" option. The system will prompt you to enter a new temporary password that will replace the current lock screen.
- 🔑 Enter a new access code in the field on Google.
- 📱 Click the "Block" button to send a command to your smartphone.
- 📲 Enter the resulting code on the screen of the blocked Redmi 4.
- ✅ After successful unlocking, immediately change the password in the security settings.
The effectiveness of this method on modern versions of Android and MIUI can be limited by security policies. Often Google only allows remote locking or data cleaning, but does not always allow you to change the pin code on a working device without root rights.
Use of Fastboot Mode and Mi Flash Utility
For advanced users who don’t have standard methods, there is the option of flashing the device in Fastboot mode.This mode is designed for low-level interaction with the hardware of the smartphone and allows you to record a clean image of the system, completely ignoring the lock screen. For Redmi 4, this is one of the most reliable ways.
You will need a computer with Windows OS, USB-cable and official utility Mi Flash Tool. you also need to download the firmware (Fastboot) ROM) For your model (codename prada for Redmi 4 Prime or markw for regular Redmi 4), the firmware should be.tgz, not.zip.
adb reboot bootloaderIf the phone turns on, you can send a command via ADB. If not, press the volume and power button when the phone is turned off until an image of a rabbit repairing an android appears. Connect the device to a PC, unpack the archive with the firmware and specify the path to the folder in the Mi Flash program. Select the "Clean All" mode and press Flash.
⚠️ Attention: Fastboot flashing is critical to stability. Interrupting the process (cable shutdown, power surge) can cause the motherboard to fail completely (brick").
Once the firmware is successfully installed, the phone will boot as new, without any passwords. However, if FRP (Factory Reset Protection) protection was turned on before the device was reset, after booting, the system will require you to enter the username and password from the Google account that was synchronized earlier, a standard protection against theft that can not be circumvented by simple firmware reflashing.
What is FRP and how to live with it?
Comparative table of unlocking methods
To make it easier for you to choose the right option, we have systematized the basic methods in the table, and pay attention to the requirements for each method and the possible consequences for your data.
| Method | We need the Internet. | Data retention | Difficulty |
|---|---|---|---|
| Mi Cloud (Find Device) | Yeah (on the phone) | Yes. | Low. |
| Google Find My Device | Yeah (on the phone) | No (usually reset) | Low. |
| Recovery (Wipe Data) | No. | No. | Medium |
| Mi Flash (Fastboot) | No (PC needed) | No. | Tall. |
As you can see from the table, the only way to save information is to use cloud services, provided that the phone was online. All other methods involve a complete cleanup of the user partition, which is the price that you have to pay for a forgotten pattern lock in modern security systems.
The choice of method also depends on your technical background, if you are not confident in your abilities when working with Fastboot or ADB-It is better to limit the Recovery menu or contact the service center, so as not to aggravate the situation with software errors.
Prevention and backup
After successfully unlocking or resetting Redmi 4, it is critical to take action to ensure that things don't happen again. The best protection against data loss is regular backups. MIUI has a powerful backup tool built in that not only saves contacts and messages, but also saves system settings.
It is recommended to set up automatic sync with Google Photos for media files and with Google Contacts for phone book. For deeper backups, you can use local saving to a memory card or computer through the Mi PC Suite program (or its analogues).

Advice: Write down your own PIN-The code and pattern lock are placed in a safe place (notebook, password manager) immediately after installation. Human memory tends to forget numbers, especially if the code is rarely used.
It’s also worth checking the Smart Lock settings, which lets you unlock your phone automatically in certain conditions: when it’s in your pocket (pedometer detection), next to a trusted Bluetooth device (like a fitness bracelet), or in a safe place (at home), making it much easier to access the gadget in your daily life.
⚠️ Warning: Smart Lock reduces overall security, and if you lose your phone in a "safe place" or near a trusted device, anyone who finds it will have access to your data without a password.
Remember to check the relevance of your account data periodically. Changing your email or phone password without updating it in your phone settings can result in you being unable to pass two-factor authentication or restore access through search services at a critical time.
💡
Keeping your phone in sync with the cloud regularly is the only guarantee that losing access to your phone won’t be the loss of your entire digital life.
