Xiaomi’s mobile devices are notoriously reliable, but over time, even the most stable systems can accumulate software errors. If your Redmi Note 5a starts to run slowly, freeze or consume battery power faster than usual, a radical but effective solution is to return to its original state.
Before you start taking action, you need to understand the essence of the process: Hard Reset is not just a reboot, it is a complete formatting of the system partition. All your photos, contacts, messages and installed applications will be permanently deleted, which is why it is critical to back up important data in the cloud or on your computer beforehand.
In this guide, we will discuss in detail two main methods of performing this operation: regular, through the operating system settings menu, and forced, through Recovery Recovery mode. The second method is especially relevant if the device is locked or does not boot correctly.
Preparation of the device for the discharge procedure
The initial stage is the foundation of a successful operation. Ignoring the preparatory steps can lead to loss of important data or interruption of the process halfway. Make sure that the battery level of your Xiaomi Redmi Note 5a is at least 60-70%.
The second mandatory step is a Google account and Mi Account. If you plan to sell a phone or transfer it to another user, you need to untie accounts in advance, otherwise FRP (Factory Reset Protection) protection will work, and the new owner will not be able to activate the device without your password.
- 📸 Back up photos and videos via Google Photos or copy them to your computer.
- 📞 Sync your contacts with your Google account or export them to a.vcf file.
- 🔑 Write down or remember passwords from accounts that were linked to the phone.
- 📶 Extract. SD-map SIM-map before the procedure to avoid random formatting of external media.
⚠️ Note: After resetting the settings, remove SD-It's too late if you've chosen the option of cleaning the external drive, and physically removing the memory card is the most reliable way to keep its contents intact.
It is also worth checking for important files in download and instant messenger folders. Often users forget about documents downloaded from the Internet or voice messages in messengers stored locally. The reset process is irreversible: it will not be possible to restore data without a pre-created copy using standard means.
Method 1: Reset via the settings menu (standard method)
The safest and easiest option available if you know the unlock code and the phone is switching on normally, this method allows the system to correctly complete all background processes before cleaning. Go to the main menu and select the Settings icon.
In the list that opens, find the About Phone section, which is usually at the bottom of the list. Inside this menu, you'll need to find Reset. The MIUI shell interface may vary slightly depending on the firmware version, but the logic remains the same.
The system will offer two options: Reset (saves files) and Erase Everything (full reset), and we are interested in the second option, after selecting the system will request confirmation of the action and possibly enter a pin code or pattern lock to confirm the identity of the owner.
☑️ Checklist before pressing the button
Once confirmed, the deletion process will begin, which will take 5 to 15 minutes, the screen may go out and light up, the phone may vibrate — that's normal behavior. Don't interrupt the process and wait for the language selection welcome screen to appear.
Method 2: Hard Reset with Recovery Mode
If the device doesn't boot, freezes on the logo, or you forget the pattern lock, you'll need to use a recovery mode. This method works at the level of low-level software, bypassing the operating system. To log into Recovery on the Redmi Note 5a, you need to turn off the smartphone completely.
Press both the Volume Up and Power button at the same time. Hold them until the Mi logo appears, then release the power button, but keep the volume up until the Recovery menu appears. This menu is controlled by volume buttons and power buttons.
| Action on the menu | Control button | Description of function |
|---|---|---|
| Navigation up/down | Volume +/- | Moving the cursor by menu items |
| Confirmation of choice | Power (Power) | Activation of the selected point |
| Wipe Data | Choices in the menu | Section for data resetting and cleanup |
| Reboot | Choices in the menu | Rebooting the device in normal mode |
In the main menu, select Wipe Data, then Wipe All Data. The system will warn you of loss of information. Confirm the action by selecting Confirm. After cleaning, select Back to Main Menu and then Reboot -> Reboot to System.

Solving the Mi Account Problem (FRP Lock)
Modern Xiaomi smartphones are equipped with a security system that links the device to the owner's account. Once the settings are reset, the phone will require you to enter the password from the last Mi Account and Google Account used. This is a theft protection known as FRP.
If you forget your password, it can take time to restore access, you will need access to your linked phone number or email for the recovery procedure through the official mi.com or accounts.google.com. Without this data, it is extremely difficult to unlock the device legally.
In case the phone was bought with hands and the previous owner did not untie the account, you will have to contact it. Xiaomi technical support can also help if there is a check for the purchase of the device confirming your ownership.
⚠️ Attention: Attempts to bypass protection FRP using third-party software can cause a full lock of the motherboard (Hard Brick.
Initial adjustment after reset
Once you have successfully restarted, you will see a welcome screen. Choose the language you want and click Start. Then you will be connected to a Wi-Fi network. This is a must-have step for activating the device and checking accounts.
If you've previously created a backup in Google Drive or Mi Cloud, select this option. The phone will automatically download contacts, call history and a list of previously installed applications. This process can take anywhere from 10 to 30 minutes depending on the amount of data.
At the security setting stage, it is recommended to immediately install a new unlock method: a pattern lock, pin code or fingerprint (the sensor is located on the back of the Redmi Note 5a), which will ensure that your data is protected from the first seconds of use.
💡
When you first set up, turn off automatic updates to all apps on Google Play if you have weak internet, which will prevent the device from overheating and allow you to complete the setup faster.
Optimizing the system after cleaning
Immediately after reset, the system may not work perfectly quickly in the first few days. 15-20 This is because the background services index files and optimize databases. Let the phone lie down with the screen on while charging to complete these processes.
It is recommended to check for operating system updates. Go to Settings -> About Phone and click on the MIUI version. Installing the current firmware version can fix bugs present in the old version.
Also, you should review the list of installed applications: do not install all programs at once, but introduce them gradually to identify possible conflicts or “heavy” applications that slow down.
💡
A complete reset not only clears the memory, but also eliminates deep system errors that cannot be fixed by a conventional reboot or cache cleaning.
