Xiaomi’s Redmi series has a reputation for being reliable, but even the most powerful gadgets require a major intervention over time. A complete cleanup of the Xiaomi Redmi 5 Plus may be needed for a variety of reasons, from selling the device to a new owner to fixing serious software failures that cannot be fixed by standard methods. It’s important to understand that this process is irreversible, so preparation is a critical part of the procedure.
Before you take any drastic action, you need to be aware of the difference between simply uninstalling apps and fully formatting the system partition. The Redmi 5 Plus cleanup process not only deletes your personal files, but also resets all system settings to the state in which the phone left the factory assembly line. This means that once turned on, the device will require an initial setup, as in the first purchase. Follow the steps carefully to avoid losing important data or locking your account.
Preparing the device for a complete data reset
The first and most important step is to create a full backup of all important data. The built-in MIUI tools allow you to save contacts, messages, call history and even home screen layout to the Mi Cloud service or local storage. Don't ignore this step, as it will be almost impossible to recover deleted files without a backup.
Be sure to check the link between your Mi Account and your Google account. If you plan to transfer your phone to another person, log out of all accounts before you start resetting. Otherwise, anti-theft protection will work, and the new owner will not be able to activate the device without your password. This is a standard security measure, but it often causes the devices sold to be blocked.
☑️ Checklist before reset
If a microSD card is installed in the device, it is better to remove it before starting the procedure. Although modern versions of Android and MIUI usually require confirmation before formatting an external drive, the risk of accidental data loss on the flash card is too high to risk.
Cleaning through the system settings menu
The easiest and safest way to bring the Xiaomi Redmi 5 Plus back to factory status is to use the standard settings menu, which is available if you can unlock the screen and log in to the operating system interface. To start, open the Settings app and find the Advanced Settings section, which is usually located at the bottom of the list or in the About Device category depending on the firmware version.
Inside the menu, find Recovery and Reset. There are several options that you can find, but we're interested in Setting Reset. When you click on this button, you'll see a warning that all data will be deleted. The system will also show you a list of what will be deleted: photos, music, documents and installed applications.
What happens to system updates?
To confirm the action, you will need to enter a graphical key or screen unlock password, if installed, this is protection against accidental reset by children or unauthorized persons, and after confirmation, the cleaning process will begin, which can take from 5 to 15 minutes depending on the amount of memory filled.
Using Recovery Mode for Deep Cleaning
If the operating system is damaged, the phone freezes on the logo or does not respond to touch, you will have to use Recovery Mode Recovery Mode. This method allows you to clean the device at a deeper level, bypassing the MIUI interface. To enter this mode, you need to completely turn off the smartphone and then press the power and volume buttons simultaneously.
Hold the buttons until the Mi logo appears, then release the power button, but continue to hold the volume button until the Recovery menu appears. Navigation in this menu is done with volume buttons (up/down), and the choice of item is made by the power button. You need to find the Wipe Data or Wipe & Reset item.
💡
Use the original cable or make sure the phone is at least 60% charged before logging into Recovery, as the formatting process consumes energy and discharging at a critical moment can damage the file system.
In some versions of the recovery, you may need to confirm the action by entering the word "yes" or selecting an additional Wipe All Data item. Be careful: in Recovery mode, there is no option to cancel the action if you have already confirmed the choice. After cleaning, select Reboot to reboot.
Deletion of accounts and protection against blocking
One of the most common problems after selling or resetting a phone is blocking activation. Google and Xiaomi have implemented security mechanisms that link the device to the last account entered. If you simply reset the data without first logging out of the account, the phone will require you to enter a password from this account when you first set up.
To avoid a situation where a device becomes a “brick” for a new owner, be sure to manually unwind. Go to Settings → Accounts and Sync. Here you will see a list of all authorized services: Google, Mi Account, Exchange and others. Select each account and click Delete Account or Sign Out.
| Type of account | The risk of blocking | Pre-discharge action |
|---|---|---|
| Mi Account | Tall (Find Device) | Mandatory exit |
| Google Account | High (FRP Lock) | Mandatory exit |
| Social media (VK, FB) | Low (access to data) | Recommended exit |
| Applications of banks | Medium (access to finance) | Mandatory unbundling |
Pay special attention to banking applications. Even after a reset on the servers of banks, the device can be linked to your account. It is best to call the bank before selling or cleaning, or use the bank's web version to remove the Xiaomi Redmi 5 Plus from the list of trusted devices.
Cleaning cache and temporary files
In addition to user data, the phone accumulates a huge number of temporary files that can slow down the system. Even after resetting, it is recommended to carry out additional cleaning of the system cache to prevent the possibility of recovering deleted data with special utilities.
Once you enter recovery mode, select Wipe Cache, which is safe for your personal files (unless you have already done a full reset), as it only deletes application temporary data and system logs. However, if your goal is to clean up completely before selling, this step is done automatically with Wipe Data.
⚠️ Warning: Don't confuse Wipe Cache and Wipe Data. The former only cleans up trash, the latter deletes all your photos, contacts and apps irrevocably. Read menu item names carefully before pressing the confirmation button.
For those who want to make sure that data can't be recovered, there's a "rewrite" method. After the first reset, set the phone as new without entering personal data, and fill the memory with useless files (e.g., shoot a few hours of video in maximum quality), then reset again, ensuring that the old memory sectors are physically overwritten with new information.
Solving problems after cleaning
Once the Xiaomi Redmi 5 Plus has finished cleaning and restarted, you will see a welcome screen, at which point the system may require a Wi-Fi connection to check for activation, if you forgot to delete your accounts, this is where the password request will appear. If you did everything correctly, the phone will start as standard.
The first run can take longer than usual, up to 10-15 minutes. This is normal behavior, as the Android operating system optimizes applications and creates new system files. Do not try to interrupt this process or remove the battery (if it is not removable) so as not to damage the bootloader.
💡
The first download after a full reset always takes longer than usual — it's system optimization, not a bug. Give the phone time to complete the process.
If the phone is stuck on the logo or goes into a cyclic restart (bootloop), it may have damaged the system partition or interrupted the recording process, in such cases, you need to flash the device through the computer using the Mi Flash Tool utility and the official firmware for your model.
