Xiaomi Redmi smartphones are deservedly popular due to the balance of price and quality, but even reliable devices can face software failures over time. The Redmi Note 5A model, released in 2017, is still actively used, and owners often wonder how to completely clean up the system from accumulated debris or remove a forgotten pattern lock. The procedure for returning to the original state is a radical, but often the only sure way to revive a device that began to work slowly or incorrectly.
In this article, we will take a look at all the available methods, from standard reset via the settings menu to forced Hard Reset through the Recovery engineering menu. You will learn what data will be irretrievably lost, how to properly prepare the device for the procedure and what to do if the system is blocked by a Google account or Mi Account. It is important to understand that restoring factory settings is not just deleting files, but a deep restructuring of the MIUI software shell.
Before you take action, you need to realize the seriousness of the step: all your personal photos, contacts, messages and installed applications will be destroyed. If you have access to the system, be sure to back up important data in the cloud or on your computer. Ignoring this step can lead to the loss of valuable information, which will later be extremely difficult or impossible to recover even with specialized software.
Preparation of the device for complete reset
The first and most critical step is to ensure a stable power supply. The system partition formatting process can take 10 to 30 minutes, and if the battery runs out at this point, there is a high risk of damage to the bootloader or file system errors. Charge your Redmi Note 5A to at least 60-70%, and ideally up to 100%, to rule out any shutdowns during the critical phase of operation.
Next, you need to take care of data synchronization. Owners of Xiaomi devices have the ability to use the built-in Mi Cloud service, which automatically saves contacts, notes, voice recordings and call schedules. For heavier files, such as photos and videos, it is recommended to use Google Photos or manually copy the contents of folders. DCIM Download to an external drive or PC via USB-cable.
⚠️ Warning: Make sure you remember the password from your Google account and Mi Account. Once reset, the system will require authorization to these services as a measure of protection against theft.If you don't know the passwords, the device can turn into a blocked-access "brick.
It is also worth checking the presence SD-While standard resetting through settings does not usually affect external memory, using the Hard Reset method through Recovery sometimes gives you the option to clean everything, including the internal drive. If there are important files on the memory card, remove them before starting the procedure or make sure that only system partitions are selected.
☑️ Checklist before reset
Reset via the Android settings menu
The safest and easiest way to get the Xiaomi Redmi Note 5A back to factory status is available right from the operating system running.This method is ideal if you're planning to sell the phone or just want to start from scratch, and you have full access to the interface. First, go to the main menu and select the Settings icon, which usually looks like a gear.
In the list of options that opens, you need to scroll down to the Additional section (in some versions of MIUI it may be called Advanced Settings). This is where the system management tools are hidden. Find Recover and Reset and click on it. The system will alert you that all data will be deleted and suggest you choose the source of the reset.
You need a Reset Settings that returns the settings to factory settings, not just Reset Wi-Fi or Reset Network settings. After selecting, the system will request confirmation again, you may need to enter your current screen unlock password or PIN-code.

Once confirmed, the phone will restart and the cleaning process will begin, the screen may go out and light up, and the MI logo will appear several times. Do not interfere with the process until you see the welcome language selection window. This means that the procedure has been successfully completed and the device is ready for initial setup.
💡
If the phone offers to upgrade before reset, it’s better to agree.This ensures that after cleaning you get the latest version of MIUI with the latest security patches.
Hard Reset via Recovery Mode
There are different situations: the phone can freeze on the logo, not respond to the touch of the screen or forget the pattern lock, in which case the only way out is to use Recovery mode, a special diagnostic mode built into the device's memory, which allows you to control the system bypassing the main Android interface.
To enter this mode on the Redmi Note 5A, you need to turn the device off completely. Then press two buttons simultaneously: Volume Up and Power. Keep them clamped until the MI logo appears, after which the power button can be released, continuing to hold the volume key. In a few seconds, you will see the Recovery menu, where the control is carried out by the volume buttons (up/down), and the choice is made by the power button.
From the Recovery menu, select the language (usually English and Chinese), then go to Wipe & Reset. Here you will be offered two options: Wipe All Data (complete clean) and Wipe Data (clean without deleting media files if supported by the Recovery version). To completely reset, choose the first option. The system can ask for confirmation several times, requiring you to choose Confirm or OK.
⚠️ Attention: In Recovery mode, the touch screen is not working, navigation is done exclusively with mechanical volume buttons to move through the menu and a power button to confirm the choice.
After completing the cleaning process, which will take some time, you will return to the main Recovery menu.Select Reboot and then Reboot to System.The first on-line after Hard Reset can last longer than usual (up to 5-7 minutes), as the system recreates configuration files and checks the integrity of partitions.
What happens if Recovery does not open?
Removing locks via Fastboot (for advanced)
For users who are faced with more complex problems, such as cyclic reboot or the need to flash, there is a Fastboot mode. On the Xiaomi Redmi Note 5A, it is often used to deep restore the system using a computer. Enter this mode by pressing the Power and Volume Down button when the phone is turned off.
In Fastboot mode, the screen usually shows a hare in a hat-eared android repairing. From here you can clean the data by selecting an option via a menu or using commands on the computer. This will require an installed ADB/Fastboot driver and a connected PC. The fastboot erase userdata command allows you to erase the partition with user data, which is equivalent to a complete reset.
However, it is worth noting that using Fastboot requires more technical literacy. Mistakes such as erasing system partitions instead of user partitions can lead to complete inoperability of the device.
If the phone is locked with a Mi Account, a Fastboot reset will not bypass the protection unless the bootloader is unlocked. Unlocking the bootloader requires waiting 168 hours (7 days) after the account is tied in the phone settings, which is Xiaomi's standard security procedure.
💡
Fastboot mode is a powerful recovery tool, but using it without knowledge can permanently disable your phone. Use only if methods through Recovery haven't helped.
Typical problems and ways to solve them
Despite the simplicity of the procedure, Redmi Note 5A users may face a number of challenges, one of the most common is the requirement to activate after a reset. If the phone was linked to Mi Account, the system will require you to enter a password from this account, which is protection against theft, and it is impossible to circumvent it in legal ways without a password.
Another problem is the “bootloop” cycle, where the phone is constantly rebooted without reaching the desktop, in which case a normal reset via the menu is impossible, and you have to use Recovery. If Hard Reset does not work, the problem can be in the damage to system files or physical wear of flash memory, which requires reflashing through the computer using the Mi Flash Tool utility.

Setting up your smartphone after cleaning
When you're done and you see the welcome screen, you start the setup phase. Select your language and connect to the Wi-Fi network. The system will offer to restore data from the backup. If you've used Xiaomi or Google services, you can get your contacts back, your call history back, and even your icons' location on your desktop.
An important step is to update the applications and the system itself. Go to Settings → About Phone → System Update and check for new versions of MIUI. This will ensure stable operation and close security vulnerabilities. Also remember to reconfigure your fingerprint or face if your Redmi Note 5A supports these biometrics features.
Now your phone is clean as new. It needs to run faster, random freezes disappear, and memory space is maximized. Clean your cache regularly and don't install apps from questionable sources to keep the device's performance high for as long as possible.
💡
After the reset, install the antivirus immediately and check the phone, which will help make sure that the cause of the problems was not malware that could come back from the backup of the applications.
