Xiaomi Redmi Note 5a, despite its age, remains a reliable device, but over time the software can fail. Users often face a buildup of system debris, sudden interface freezes or the inability to unlock the device due to a forgotten pattern lock. In such situations, the most effective solution is to return to the original state of the system, which allows you to eliminate software errors and restore the functionality of the gadget.
The full reset procedure, known as Hard Reset, completely clears the device’s internal memory of user data, including contacts, photos, installed apps and accounts. This is a radical method that requires prior preparation, since it will be impossible to return deleted information without a backup. It is important to understand the difference between a simple reboot and a full formatting, so as not to lose important files by negligence.
In this guide, we will take a detailed look at all the ways available to restore the Redmi Note 5a to factory status. You will learn how to clean through the standard settings menu if access to the system is saved, and how to use Recovery mode if the phone is not turned on or locked. Following the instructions will help to safely resuscitate the device.
Preparation of the device for complete reset
Before any manipulation of system files begins, a number of preparatory steps must be taken, and ignoring this stage can lead to permanent loss of personal data or problems with activating the device after rebooting.
The first and most critical step is to back up all important information, with built-in MIUI tools that save contacts and calendars to the Google or Mi Cloud cloud, and photos and documents better copied to a computer or external drive, and be sure to check the synchronization of messengers such as WhatsApp or Telegram to save your correspondence history.
⚠️ Warning: Make sure the battery level is at least 50-60%. If the device turns off during the system partition formatting process, it can damage the bootloader and turn the phone into a “brick».
Another important thing is that you unplug your Mi Account, and if you have Find Device enabled on your phone, after you reset, the system will require you to enter the password from the account you previously linked to, so if you don't remember the login details, the phone will remain locked, so you'd better delete the account through the settings menu in advance.
- 📸 Back up photos and videos to your computer or cloud storage.
- 📞 Keep your contacts in. SIM-Map or export them to file.vcf.
- 🔋 Charge the Redmi Note battery 5a minimum%.
- 🔓 Untie Mi-account and Google-account in the device settings.
Once you've done these steps, you can go directly to the discharge procedure, and you don't have to rush it, because careful preparation takes a little while, but saves you from a lot of potential problems in the future.
Reset via the settings menu (Soft Reset)
If your Xiaomi Redmi Note 5a is functioning normally, turns on and you have access to your desktop, use the standard reset method. This is the most secure and soft option that correctly closes all processes and cleans data without the risk of damaging system files.
To start, open the main menu and look for the Settings icon. Depending on the version of the MIUI firmware, the interface may be slightly different, but the logic remains the same. You need to find the section that deals with the general system settings, which is usually called About Phone or Advanced Settings.
Next, select Reset (sometimes hidden in the “Advanced” sub-menu. The screen will display a warning that all data will be deleted. The system will offer several options: reset only settings or erase all content. To return to full factory state, select the option “Erase everything”.
⚠️ Note: This method may cause the phone to reboot several times, and do not interrupt the process or press buttons until the language selection menu appears on the screen.
Once confirmed, the device will begin the cleaning process, which can take 5 to 15 minutes depending on the amount of memory filled, and when completed, the Redmi Note 5a will turn on as new, requiring initial setup.
- 📱 Go to the Settings menu → The phone.
- 🗑️ Select "Settings Reset" or "Factory Reset».
- ✅ Click the “Erase Everything” button and confirm the action with a password or pattern lock.
This method is ideal for selling a smartphone or transferring it to another user, as it ensures the deletion of personal data when the operating system is working.
Hard Reset via Recovery Mode
When the Xiaomi Redmi Note 5a doesn’t respond to touch, hovers on the logo, or you forget the unlock password, the only way out is to use Recovery Recovery Mode. This method works at the bootloader level and does not require access to the operating system.
To enter this mode, you need to turn the device off completely. Then simultaneously press the Volume Up and Power button. Hold them until the Mi logo appears on the screen, after which the power button can be released, while continuing to hold the volume key.
The Main Menu will open, where the volume buttons (up/down) control the menu, and the power button confirms the choice. You will need to find the Wipe Data item. In some versions of Recovery, you may need to select Wipe All Data for full formatting.
The system will request confirmation, often by selecting Confirm or entering the word "yes" (depending on the version), after confirmation, the process of erasing the data and cache sections will begin, and the message "Data wiped successfully" will appear after completion.
☑️ Hard Reset Checklist
It is important to note that after this procedure, the device can boot longer than usual for the first time. This is normal, since the system creates new configuration files.
Comparison of data dumping methods
Users often get confused about the terms, not understanding what kind of cleaning they need, different methods have their own technical features, depth of impact on the system and requirements for the state of the device. Below is a table that helps determine the choice.
| Parameter | Through Settings. | Recovery Mode | Mi Flash (PC) |
|---|---|---|---|
| Access to LOs | Required. | Not required | Not required |
| Difficulty | Low. | Medium | Tall. |
| Risk of error | Minimum | Low. | Medium. |
| Deletion of Mi-account | Automatically. | Remains (FRP) | Depends on the firmware. |
As you can see from the table, the method through settings is the most preferred for the average user, since it automatically untie accounts and reduces the risk of blocking.
The use of the computer and the Mi Flash utility is only required in complex cases, such as flashing or recovering from a failed update. For standard data reset, this method is redundant and requires drivers and skills.
⚠️ Warning: When reset via Recovery or Fastboot, some firmware versions may have protection. FRP (Factory Reset Protection means that after the reset, the phone will require you to enter a Google account that was previously synced.
Choose a method based on the current state of your Redmi Note 5a. If you can access the menu, use it. If the phone is hanging, go to the buttons.
Solution: Forgot password and lock
One of the most common causes of resets is the loss of access to the device, PIN-A code or password from the lock screen, you can't log in to the system, and in this case, only Hard Reset via Recovery will help.
But there's a caveat that not everyone knows about: Once reset and turned on, the phone may require you to enter a password from a previously used Google account, which is an Android security measure designed to protect the owner's data in the event of theft. If you don't remember the password from your Google account, it will be extremely difficult to unlock the device without contacting the service.
What to do if your phone requires an old account?
Also worth mentioning is the Mi Account situation: If the Find Device feature was active, the phone will be locked before entering the password from the Xiaomi account. Resetting through settings automatically removes this anchor, while button resetting does not.
To prevent these situations, always write passwords from your primary accounts to a secure location or use password managers, which will save you a lot of time and nerves at a critical time.
Initial adjustment after reset
Once the reset is completed, the Redmi Note 5a will start in initial settings, and the welcome screen will prompt you to select a language, region, and connect to a Wi-Fi network, which is important for activating all services.
The system will offer to restore data from the backup if you have created it before. You can choose to restore from the Mi Cloud cloud or local backup, which will allow you to quickly return contacts, call settings and a list of installed applications without configuring the phone from scratch.
Be sure to check for system updates immediately after setting up. Go to Settings → About Phone → System Update. Installing the current version of MIUI will close known security vulnerabilities and improve stability.
💡
When you first set up, take your time to install all the apps at once. Give the system 10-15 minutes after turning on to optimize the database, otherwise the phone may run slowly in the first hours.
Finally, set up biometric protection (fingerprint or facial recognition) if your Redmi Note 5a model supports these features, which will ensure convenient and secure access to your data in the future.
💡
Proper initial setup and recovery from the backup allows you to return the phone to working condition in 20-30 minutes, saving all the important data.
