How to format Xiaomi Redmi 4A phone: all methods

The Redmi 4A series is deservedly considered one of the most reliable budget devices of its time, however, even they can face software errors, accumulation of system debris or the need to transfer to a new owner. Full formatting is a radical, but often the only sure way to return the gadget to factory speed and eliminate deep system failures that are not solved by conventional cache cleaning.

The process of preparing the device for resale or elimination of critical errors requires careful approach, since Xiaomi Redmi 4A has its own features in the structure of the MIUI menu. Before starting any manipulations, you need to clearly understand the difference between simple deleting files and deep cleaning of memory partitions, which will affect all user data without the possibility of their simple recovery.

In this guide, we will discuss in detail all available ways to return the system to its original state, including standard settings, recovery mode and the use of specialized software for PC. Importantly, formatting permanently deletes all photos, contacts and applications, so creating a backup is a mandatory first step. Follow the instructions consistently to avoid blocking your account or damaging system files.

Preparation of the device for complete reset

Before starting the cleaning procedure, it is critical to perform a number of preparatory actions, ignoring which can lead to the loss of important information or locking the device with MIUI protective mechanisms. First of all, make sure that the battery charge is at least 50-60%, since a sudden power outage during the system partition formatting can turn the phone into a “brick”.

Be sure to unplug your Google and Mi Account if you plan to sell the device or transfer it to another person. Otherwise, FRP (Factory Reset Protection) protection will work, and the new owner will not be able to activate the smartphone without entering your username and password.

• 📸 Back up all important photos and videos to your computer or cloud storage.
• 📞 Export contacts to a.vcf file or sync them with your Google account.
• 🔑 Write down passwords from important apps, as they will be deleted after reset.
• 📱 Remove the microSD card if it is installed so you don’t accidentally format it.

It is also worth checking for important license keys or program activation files that can be linked to a particular device ID. Once reset, the identifiers may change or be lost, which will require software developers to re-activate licenses.

Method 1: Reset via the standard settings menu

The safest and easiest method available to every user is to use the built-in reset function in the MIUI interface. This option is suitable if you remember the screen unlock password and have access to the phone menu. Go to Settings, then select Advanced Settings (or "Additional" in older versions of the firmware).

In the list that opens, look for Restore and Reset, and here the system will offer two options: Reset (without deleting data) and Clear Everything (full formatting), and we are interested in the second option, which will return the phone to the state "out of the box", click on the corresponding button and confirm the action by entering the unlock password.

Once confirmed, the system will alert you to the consequences again. If you're confident in your decision, start the process. The phone will reboot, the Redmi logo will appear, and then the clean-up progress indicator will appear. Don't touch the device until the desktop is fully loaded.

If the phone hangs on the logo for a long time after reset, wait 10-15 minutes – the system optimizes applications.

Method 2: Formatting with Recovery Mode

If the operating system is damaged, the phone does not turn on or you forgot the pattern lock, you will have to use Recovery mode. This is a special diagnostic interface, sewn into the memory of the device regardless of the main OS. To log in on the switched off Xiaomi Redmi 4A, you need to press the volume button "Up" and the power button at the same time.

Hold the buttons until the Mi logo appears, then release the power, keep the volume up. When the menu with the black background and orange/blue labels appears, the control is done with the volume buttons (up/down), and the choice is with the power button. You need to find the Wipe Data item.

⚠️ Attention: In Recovery mode, the touch screen is not working. All navigation is done exclusively with physical volume and power buttons.

Inside the Wipe Data menu, select the Wipe All Data option. The system will request confirmation again, as this is a critical action. Once confirmed, the data and cache partitions will be erased. Upon completion, the phone will prompt you to return to the main menu (Back to Main Menu) and restart (Reboot).

Using the Mi Flash Tool for deep cleaning

For advanced users facing serious software failures or viruses, there is a tool called Mi Flash Tool, which is the official tool from Xiaomi, which allows you to reflash the device cleanly, including formatting all memory partitions, USB-cable and downloaded firmware image (Fastboot) ROM) for Redmi 4A (codename: rolex/riva).

The process begins with the transfer of the smartphone to Fastboot mode. To do this, on the device turned off, press the power and volume buttons "Down" simultaneously until the image of a hare repairing an android appears. Connect the phone to the computer through the computer USB-Make sure the drivers are in the port. ADB/Fastboot correctly.

In the command line, this command must output the serial number of the device, which will confirm the successful connection. In the Mi Flash Tool, choose the path to the unpacked firmware. Critically, in the lower right corner of the interface, select the option clean all or clean all and lock. The first option will simply format the memory, the second will also block the bootloader.

• 💻 Download the current Fastboot firmware for your model.
• 🔌 Use the original. USB-risk-mitigating cable.
• 🚫 Do not interrupt the firmware process and do not turn off the cable.

When you press the Flash button, you start writing, the progress window will show the status of the operation, the phone will automatically restart when it's done, and it can take up to 10 minutes to start up, as the system will create new file system partitions.

Delete Google Account (FRP) and Mi Account

One of the major problems after formatting is FRP (Factory Reset Protection) blocking. If you don't delete your Google account before resetting, the system will require you to enter your password from the last synchronized mailbox when you first activate it, which is anti-theft protection, and it's almost impossible to circumvent it legally without a password.

The same is true of Mi Account, where if you have enabled device search in your phone settings, you will need to enter your Xiaomi account password after reset, and without that, your phone will remain locked forever. So the rule is simple: go to Settings → Mi Account and click Log Out before any formatting.

⚠️ Warning: When buying a used Xiaomi phone, always ask the seller to reset and activate the device to make sure that there is no link to other accounts.

If you forget your Mi Account password, restore it through i.mi.com before the reset procedure begins.Attempts to use third-party programs to bypass FRP often result in malware installation or the device permanently locked over IMEI.

Solving problems after formatting

Once the procedure is completed successfully, users may encounter a number of typical situations: for example, the phone can take a long time to load or heat up in the first 30 minutes of operation. This is normal behavior: Android background services index files and optimize the database. Let the device lie on a charge with the screen off.

Another common problem is the lack of communication or IMEI. If network settings are lost after running through the Mi Flash Tool, the persist or modem partition may have been damaged. In this case, you will need to restore the EFS backup or reflash the stock version with the correct drivers.

It is also worth noting that after a reset, some features may not work if custom firmware was installed instead of stock, and it is recommended to always return to the official global or Russian version of MIUI for stable operation of communication modules and camera.

💡

If the phone warms up and discharges quickly after reset, that's normal in the first hours.
