Xiaomi Redmi smartphones have proven to be reliable devices, but over time, even the fastest processor can slow down due to accumulated software debris. Users often face a situation when the gadget begins to work unstable, system errors appear or there is a banal lack of memory to install new applications.
The formatting procedure, or hard reset, deletes all user data, returning the device to the “out of the box” state. This is not just deleting files, but deep processing of system partitions, which eliminates software problems that cannot be fixed by conventional methods. Before you start manipulating, it is important to realize that all your contacts, photos and installed programs will be irretrievably lost if you do not take care of the backup in advance.
Owners of the Redmi 6A model can perform this operation in two main ways: through the standard operating system settings menu or using the Recovery Mode Recovery mode. The first option is suitable if the phone turns on and responds to commands, and the second is necessary when the screen is locked, a forgotten pattern lock or a serious interface freeze. Below we will discuss both methods in detail, paying special attention to preparing the device.
⚠️ Note: Before starting the procedure, be sure to remove SIM-microSD card and memory card, if installed, will help to avoid the accidental deletion of personal data from external media.
Preparation of the device for complete reset
Any radical action with the operating system requires prior preparation to minimize the risk of loss of important information. First of all, you need to back up all relevant data. In the MIUI shell, which is installed on the Redmi 6A, there are built-in tools for this, but you can also use cloud services or a computer.
Make sure the battery level is at least 50-60%.The formatting process can take 10 to 30 minutes, and a sudden power outage in the middle of the procedure can damage system files and turn the phone into a "brick."If the battery is drained, connect the device to the original charger.
Special attention should be paid to the Mi Account and Google account. Once the settings are reset, the security system will require authorization to accounts that were previously associated with the device. If you forget passwords, unlocking the smartphone will be extremely difficult, and in some cases impossible without contacting the service center with purchase checks.
- 📸 Make copies of all important photos and videos in the cloud or on your computer.
- 📞 Save your contacts in sync with your Google account so they can be restored automatically.
- 🔑 Write down or remember passwords from Mi and Google accounts linked to your smartphone.
- 🔋 Charge the Redmi battery 6A Up to 60% to avoid interruption of the process.
☑️ Readiness for formatting
It is also recommended to disable the Find Device feature in the Mi Account settings, although this is not always critical if you have a password, but having an active internet connection during a reset can automatically lock the device after a reboot if it is wanted or lost by the previous owner.
Method 1: Reset via the Android settings menu
The easiest and most secure formatting method is available if you have access to your smartphone desktop and settings menu, which is preferred by most users because it is intuitive and does not require memorizing complex keyboard combinations. The MIUI interface on Redmi 6A may vary slightly depending on the firmware version, but the logic of the actions remains the same.
To start, open the main app menu and find the Settings icon, which looks like a gear. In the list of options that opens, you need to scroll down to the Advanced Settings section or immediately look for the About Phone item, depending on the interface version. In newer versions of MIUI, the path often looks like Settings → About Phone → Reset.
After going to the reset menu, the system will offer two options: "Erase all data" or "Reset settings." We are interested in the first option, which completely clears the internal memory. When you press the appropriate button, the phone will warn about the risks and ask you to enter a pattern lock or a digital screen unlock code to confirm the operation.
| Parameter | Description of action | Impact on data |
|---|---|---|
| Resetting settings | Returns the system parameters to the factory | Photos and contacts are still available |
| Erase all data | Full formatting of internal memory | All user information is removed |
| Safe removal | Deep cleanup with sector rewriting | It takes longer, the data cannot be restored. |
| Reset via Recovery | Hardware discharge method | Complete deletion of data and cache |
Once confirmed, the system can request a password from the Mi Account, which is a measure of protection against theft, if the password is entered correctly, the deletion process will begin, which is visualized by the progress bar, during which it is strictly forbidden to interrupt the process, remove the battery (it is not removable), or try to reboot the phone with buttons.

Method 2: Hard Recovery Recovery Mode
If the smartphone is not turned on, stuck on the logo or you forgot the password to unlock the screen, the only way out is to use Recovery Mode Recovery Mode. This method allows you to perform formatting at a deeper level, bypassing the operating system. On Xiaomi Redmi 6A, this mode is entered by a combination of physical buttons.
Before you start manipulating, make sure the device is completely off. If the phone is getting stuck and unresponsive, press the power button for 10-15 seconds until the screen is fully vibrating and turned off. Then simultaneously press the Volume Up and Power buttons. Hold them until the Mi logo appears, after which the power button can be released, continuing to hold the volume.
You'll be taken to the Main Menu menu, where you'll be able to navigate with volume buttons (up/down) and the power button confirms your choice. You'll need to select Wipe Data, then Wipe All Data. The system will request confirmation again by selecting Confirm. Once you've cleaned up, select Back to Main Menu and then Reboot → Reboot to System.
⚠️ Warning: In Recovery mode, the touch screen is not working. All actions are performed exclusively with mechanical volume and power buttons.
The first download after a hard reset can take longer than usual, up to 5-7 minutes. This is normal, as the system optimizes applications and creates new system files. Don't panic if you see the manufacturer's logo for longer than a minute, just wait for the welcome screen to appear.
Delete the forgotten password and pattern lock
One of the most common reasons Redmi 6A owners look for formatting instructions is a forgotten lock password. Unfortunately, modern versions of Android and MIUI shells don't allow you to just bypass the protection. Password reset is only possible through complete deletion of data, since the encryption key is stored in a secure partition of memory.
If you remember the Mi Account password but you forgot the pattern lock, you can sometimes use the Forgot Password feature on the lock screen if the device is connected to the Internet. However, most often this method does not work, and you have to resort to a hard reset via Recovery, as described in the previous section. Once turned on, the phone will require you to enter the data of the Google account that was synced earlier.
There is a myth that flashing through a computer can bypass protection without data loss, but on modern Xiaomi devices this is almost impossible without an unlocked bootloader. Unlocking the bootloader, in turn, requires waiting 168 hours (7 days) from the date of filing an application with Xiaomi, making this method irrelevant for urgent access.
- 🔒 Hard Reset is the only guaranteed way to remove a forgotten password.
- 🌐 To activate after reset, you will need an Internet and Google account.
- ⏳ Unlocking the bootloader takes at least 7 days of waiting.
- 📱 Data without backup can not be restored after resetting the password.
It’s important to understand the difference between FRP lock (Factory Reset Protection) and conventional screen locking. FRP is a theft protection that is activated when reset via Recovery. If you don’t know the password from a Google account that was on your phone, unlocking the device will be extremely difficult even after formatting.
💡
Helpful tip: If you change your password from a Google account, wait 24 hours before trying to log in on the dropped phone.The security system can temporarily block the sign-in from the new device.
Common Errors and How to Resolve Them
Users can experience problems ranging from logo getting stuck to recovery errors, one common situation is a bootloop, where the phone is endlessly rebooted showing the Mi or Android logo, often when the data recording process is interrupted or the file system has been damaged before being reset.
If the phone writes System UI stopped after the reset or crashes constantly, try cleaning the cache. From the Recovery menu, select Wipe Data → Wipe Cache. This won’t delete your personal files (if they’re still there), but will clear temporary system files that may have been damaged.
Sometimes users encounter a “Can’t verify update” error or similar messages when trying to reset, which may indicate damage to the system partition recovery. In such cases, you may need to flash the device through the computer using the Mi Flash Tool utility, which is a more complex procedure requiring drivers and a firmware file.
⚠️ Note: If the phone requires activation after a reset with an account you don't have, don't try to guess the password repeatedly.
Another problem is the slow post-formatting experience, which is because the Android system and the ART runtime take time to optimize the installed applications and background processes. Let the phone run quietly for about 30-60 minutes before making inferences about performance.
💡
Optimize the system after reset takes up to one hour. Do not load the device with heavy games immediately after the first turn on.
