Despite their age, the Redmi Note 5 series remains popular due to its stable operation and maintainability. However, over time, the MIUI operating system can accumulate software errors, the application cache begins to take up a critical amount of memory, and the interface responds to commands with a noticeable delay. In such situations, the most effective solution is to completely return the device to its original state, which allows you to remove all accumulated digital debris and viruses.
Hard Reset or reset via the settings menu dramatically changes the state of the shell, making the phone almost new. It is important to understand that this process is irreversible for user data, so you need to carefully prepare before starting any manipulation. In this article, we will discuss in detail all available methods, nuances of working with a Mi Account account and typical errors that can occur in the process.
Factory resetting is often required not only to speed up work, but also before selling the gadget or handing it over to another user. Competently completing all the steps ensures that your personal photos, contacts and correspondence do not fall into the wrong hands. Let's consider the preparatory stage, which is the foundation for successful completion of the operation.
Preparing the device for a complete data reset
Before you start erasing information, it's critical to back up all your important files. You can use the built-in MIUI tools to save data to the Mi Cloud or to an external drive. You don't have to rely on real-time synchronization if the Internet connection is unstable, you better double-check all your photos and documents in storage.
The battery level should be at least 50-60% so that the device does not turn off at the most critical time of overwriting system files. If the phone runs out during the formatting of the data partition, this can damage the bootloader and require complex recovery through the computer. Connect the smartphone to the network or make sure that the battery is healthy.
⚠️ Note: If the phone has a lock screen, be sure to remember the password, pattern lock or PIN-Once reset, the system will require the release data to be entered for security purposes, and without it, the device will not be accessible.
It’s also worth disabling two-factor authorization in mission-critical applications if you plan to change your phone number or SIM card immediately after a reset. Make sure you remember the login and password from your Google account, as FRP (Factory Reset Protection) will request this data when you first turn on, a standard anti-theft measure that can’t be circumvented without the original credentials.
💡
Before reset, remove the MicroSD card if it is installed so that you don’t accidentally format external storage along with the phone’s internal memory.
Reset method through the Android settings menu
The easiest and safest way to bring the Xiaomi Redmi Note 5 back to factory status is to use the built-in menu of the system.This method is suitable for cases when the screen is working correctly and you have access to the desktop. First go to the main menu and select Settings, which is usually indicated by the gear.
In the list you need to find the section Advanced settings or immediately go to the item About phone, depending on the version of the firmware MIUI. Next, select the option Reset settings and click on the button Erase all data. The system will warn you that all information will be deleted, and ask to confirm the action by entering the password unlock the screen.
Once confirmed, the phone will restart and the cleaning process will begin, which can take 5 to 15 minutes, during which time the Redmi logo or download animations may be displayed on the screen, which is strictly not recommended to interrupt, and upon completion of the procedure, the device will turn on as new, suggesting you choose a language and connect to the Wi-Fi network.
☑️ Checklist before resetting
Sometimes the system may request confirmation via SMS or code input from the authenticator app if enhanced protection is enabled. Be prepared for this, especially if you have recently changed your SIM card. Once you successfully log in to your Google and Mi Account account, you will automatically synchronize your previously stored data.
Resetting through Recovery Mode (hardware method)
If the operating system is not loading, freezes on the logo or the touch screen does not respond to touch, you will need to use Recovery mode. To enter this mode, you need to completely turn off the smartphone and press the key combination: the volume button and the power button. Hold them simultaneously until the Mi logo appears, after which the power button can be released, continuing to keep the volume.
In the recovery menu, the navigation is done with volume buttons (up and down), and the option is selected by the on button. You need to find the Wipe Data item and select it. In the next menu, confirm the action by selecting Wipe All Data. The system will warn about the consequences again, then you will need to confirm the reset by selecting Confirm.
This is a deeper method, and is often used by service center wizards to fix software failures. It completely ignores the operating system state and works at the low-level bootloader level. Once you've finished cleaning, select Reboot and then Reboot to System to run your phone in normal mode.
What to do if the Recovery menu is in Chinese?
It should be noted that after such a reset, the first run can last longer than usual, up to 10 minutes. Don't panic if the phone hangs on the logo for a long time - there is a check of the integrity of the system partitions. If the device cyclically restarts after setting up, the system partition may be damaged and you need to flash it through the computer.
Dealing with Mi and Google accounts after resetting
Modern Xiaomi smartphones are equipped with a powerful security system that ties the device to the owner's account. Once the settings are reset, especially if Recovery mode was used, the phone will require you to enter a password from Mi Account, which was activated before cleaning. This is a theft protection known as Find Device.
A similar situation is happening with a Google account: if a Google account was authorized on the phone before the reset, the FRP security system will lock the device until the correct email and password are entered, and attempts to circumvent this protection by unofficial methods can lead to a complete lock of the motherboard.
| Type of lockdown | Cause of the occurrence | Method of unlocking | Risk of data loss |
|---|---|---|---|
| Mi Account Lock | The "Device Search" function is activated | Entering a password from the Mi Account | No (data already deleted) |
| Google FRP | A synchronized Google account | Entering Google Mail Data | No (data already deleted) |
| Bootloader (Bootloader) | Trying to reflash without unlocking | Official Unlocking Through PC | High (reset required) |
| Screen lock | Forgotten pattern lock or PIN | Full reset (Wipe Data) | Total loss of data |
If you forget your Mi Account password, you can restore it through the official i.mi.com website using a linked phone number or backup email. If you lose access to your phone number, the recovery procedure can take several days and require you to submit checks for the purchase of the device to the support team.
Resolving Typical Problems and Errors
Redmi Note 5 users may experience anomalies during the reset process, and one of the common problems is freezing during the “Data Cleanup” phase or endless rebooting, most often due to file system damage or the presence of broken sectors in eMMC memory, which is typical for devices with a long life.
If the phone doesn’t see the SIM card or connect to Wi-Fi after the reset, the baseline network settings may have been reset, in which case resetting the network settings via the Settings menu → Advanced Settings → Restore and Reset → Reset settings Wi-Fi, mobile Internet and Bluetooth. This will not affect personal files, but will update the configuration of communication modules.
⚠️ Warning: If after resetting the phone warms up in downtime and discharges quickly, give it to the phone. 1-2 an hour to index files and update Google services.If the problem persists for more than a day, you may need to reinstall the firmware.
Sometimes users complain that after returning to the factory settings, some system applications have disappeared, this can happen when using custom builds or incomplete reset, and in a normal situation, all the original MIUI applications must return to their places automatically.
To diagnose memory status, you can use the engineering menu by typing code ##6484## in the phone app, where you can check the touchscreen, display and other modules to rule out hardware malfunctions that are mistaken for software failures.
Optimizing the system after a clean start-up
After a successful reset and initial setup, the Xiaomi Redmi Note 5 is important to properly configure the system for maximum performance. First go to Settings → About the phone and check for updates. Installing the latest available version of MIUI will close security vulnerabilities and improve stability.
It is recommended to immediately disable advertising in system applications by going to Settings → Password and Security → Access to personal data and limit the rights for the msa service. Also, in each system application (Conductor, Downloads, Music) in the settings, you need to find the "Receive recommendations" switch and deactivate it.
💡
The system actively indexes files and learns your usage habits for the first 24 hours after a reset, so don’t panic because of temporary loss of autonomy or heat.
Don’t install dozens of apps from unverified sources. Start with a basic set, gradually adding software to track which apps are conflict-free. The clean system on the Redmi Note 5 is able to run very fast, but the “heavy” versions of modern applications can load the Snapdragon 636 processor harder than expected.
Clean the cache regularly through the standard Security app, but do not use third-party "accelerators", which are themselves sources of advertising and data collection. MIUI It is sufficient to maintain the hygiene of the system.
