Xiaomiβs Redmi Note 4 line of smartphones have proven to be reliable, but over time, even they can encounter software errors, system debris accumulation, or screen locking. In situations where the gadget starts to work unstable, freezes, or needs to be prepared for sale, the only right solution is a full reset (Hard Reset), which returns the device to a factory state, removing all user data.
The process of resetting factory settings on MIUI can be performed in several ways, each with its own characteristics and applications. It is important to understand that deleting data is an irreversible action, so you should approach the operation with the utmost care. In this article, we will discuss in detail all available methods, from simple menus to the use of engineering commands.
Before you start taking action, you need to make sure you are aware of the consequences: resetting will affect not only contacts and photos, but also installed applications, Wi-Fi settings and accounts. Proper preparation of the device is the key to successfully completing the procedure without losing important information or turning the phone into a brick.
Preparing the device for resetting settings
The first and most critical step is to save important information. Before you start the cleaning process, you need to back up all the data you plan to save, which can be photos, videos, documents and contacts stored in the memory of the Redmi Note 4.
Be sure to check the battery level. To safely perform the procedure, the charge should be at least 50-60%. If during the reset process, which can last from 5 to 15 minutes, the device turns off due to discharge, this can cause damage to the file system and the inability to boot the operating system.
- πΈ Back up photos and videos to your computer or cloud storage.
- π Sync your contacts with your Google or Mi Account to restore them quickly.
- π Make sure the battery is over 60% or plug in the charger.
- π Remember or record passwords from Google accounts and MI, After the reset, they will be required to activate.
β οΈ Note: If you forget the password from your Google account linked to your phone, the device may be blocked by the feature after the reset. FRP (Factory Reset Protection, and unlocking it without account data will be extremely difficult.
It is also recommended to remove the microSD card and SIM-The card before the procedure, although the current versions MIUI Often offered selective formatting, physical retrieval of the memory card ensures that your personal files on the external media will not be affected by accident.
Reset via the Android settings menu
The easiest and safest way to bring the Redmi Note 4 back to factory settings is to use the operating systemβs built-in menu, which is suitable when the phone is turned on, the screen responds to touch, and you can freely navigate the MIUI. The algorithm is standardized, but has its own nuances in different versions of the firmware.
To start, open the Settings app and scroll down to the bottom. You're interested in the About or Advanced Settings section, depending on the version of the shell. Next, select "Reset" or "Delete all data." The system will warn you that all data will be deleted.
In some cases, the system may request a pattern lock or digital screen unlock password, a security measure to prevent unauthorized or accidental resets, and once confirmed, the phone will restart and begin a cleanup process that will take a few minutes.
It is important to note that once the process is complete, the phone will turn on as new, requiring initial language setup and network connection. SIM-Make sure the card is not blocked. PIN-A code you may forget after a long break in use.
Hard Reset via Recovery Mode
If the Android operating system on your Redmi Note 4 is not booting, stuck on the logo or the touch screen is not responsive, the only option is to use Recovery Recovery Mode.This mode works at a low level and allows you to manage the system regardless of the state of the main interface.
To enter recovery mode, you need to turn off your smartphone completely. Then simultaneously press the volume button and the power button. Hold them until the Mi logo or Recovery menu appears. Depending on the type of firmware installed (Global or China), the menu can be in English or Chinese.
In the menu, you can navigate with volume buttons (up/down), and the power button confirms the choice. You need to find Wipe Data or Clear Data. In some versions of Recovery, you first need to select the language (English) and then go to clean. Be careful when choosing options so that you do not start flashing instead of resetting.
- π Select Wipe Data from the main Recovery menu.
- π Confirm the action by selecting Wipe All Data.
- π Wait for the message of successful completion (Success).
- π Select Back to Main Menu and then Reboot to reboot.
β οΈ Attention: In Recovery mode, the touch screen usually doesn't work. All actions are done with mechanical volume and power buttons. Don't press the buttons randomly so as not to pick the wrong command.
Once a cleanup command is selected, the system may request confirmation, especially on newer versions of MIUI. If the phone is tied to a Mi Account, it may be necessary to connect to a Wi-Fi network to verify the owner, an additional protection against theft that cannot be circumvented by a simple reset.
βοΈ Checklist before entering Recovery
Use of the Engineering Menu for Resetting
There is a lesser-known but effective method of resetting settings through the engineering menu available in dialer code, which is suitable for power users who want to quickly clear data without going through long settings menus. However, it should be used with caution, since access to hidden system functions requires accuracy.
To call the engineering menu, open the Phone app and enter a special code. Xiaomi devices often run code ##7780## or #4636##, although on modern versions of MIUI these codes can be blocked by the manufacturer. If the code is correct, a hidden test menu will open.
In the menu that opens, select Factory data reset or something similar. The system will warn you of the consequences. The good thing about this method is that it works even if you have partial interface problems, but if the phone is completely frozen, it won't help β then only Recovery.
What do I do if the codes don't work?
It's worth remembering that this method only deletes user data and settings, but not affected! System partition and update files remain intact, which distinguishes this method from full flashing. This is important if you want to clean the phone, but keep the current version of the system without having to re-download updates.
Comparison of data dumping methods
The choice of the specific method depends on the current state of your Redmi Note 4 and your goals. Each method has its advantages and limitations. Understanding these differences will help you avoid mistakes and choose the most suitable option for your situation.
Here's a table that will help you organize the information and choose the right path, and look at the health requirements of the phone and the level of access each method gives.
| Method | Requirements | Level of cleaning | Risks. |
|---|---|---|---|
| Through Settings. | Work screen, access to the menu | Complete data reset | Low, standard procedure |
| Recovery Mode | Working buttons, charged battery | Full reset + cache | Medium, the risk of user error |
| Engineering menu | Working dialer, knowledge of codes | Data resetting | Medium, codes may not work |
| Mi Flash Tool | PC, drivers, Fastboot mode | Complete flashing. | High, risk of blocking the loader |
As you can see from the table, the method through Settings is the safest for beginners, but requires system performance. Recovery Mode is a universal ambulance tool. Using the Mi Flash Tool (mentioned in the table) is already an advanced level, requiring a computer and an often unlocked bootloader, which can void the warranty.

For 90% of users, the best and safe choice is to reset via the settings menu or Recovery Mode. Using third-party software from a PC is only required in complex cases of system failure.
Frequent post-reset problems and their solution
After performing the Hard Reset procedure, users may encounter a number of typical situations that are not a breakdown, but represent the usual behavior of the system, and understanding these processes will help avoid panic and unnecessary actions.
The first turn on after a reset can last significantly longer than usual β up to 10-15 minutes. This is because the Android system recreates the file structure, optimizes applications and checks the integrity of system files, at which time the Mi or Android logo can be displayed on the screen.
- π₯ Heat: The phone can get very hot in the first 30 minutes of operation. That's OK, the processor is actively working on indexing data.
- π Battery: Autonomy on day one may be less than usual. The system must "learn" and adjust the background processes.
- π Blocking: If your phone requires a Google account or MI, protection FRP. Enter the data that was used before the reset.
β οΈ Warning: If after 20 minutes of waiting the phone is still on the bootloop screen, system files may have been damaged or the reset process interrupted.
Also worth mentioning is the issue with IMEI. Some Xiaomi models, especially those with modified software, may have network settings fly off after resetting. If you see βNo Networkβ or an unknown IMEI after turning on, you will need to restore through an engineering menu or specialized utilities, which is a more complicated procedure.

After the first turn on, take your time to install all the applications at once. Give the system 15-20 minutes of work in the background to stabilize processes to avoid lags and increased battery consumption.
Data recovery and system setup
When the phone boots successfully and the welcome screen prompts you to choose a language, the recovery phase will begin. If you followed the preparation guidelines, the process will go smoothly. Connect to the Wi-Fi network to activate the device.
When you log in to your Google account, it will offer to restore apps and settings from a backup, which is a convenient way to reclaim your habitat, but larger files like photos and videos are better copied manually or through the cloud so as not to overload your phone's communication channel and memory.
