How to reset Xiaomi Redmi 7 to factory settings: 3 proven ways

Resetting on Xiaomi Redmi 7 is a procedure that can be required in a variety of situations, from preparing a smartphone for sale to fixing software failures. However, not all users know that an incorrect reset can lead to the loss of important data or even to the “bricking” of the device. In this article, we will discuss in detail all the current reset methods, their features and nuances, which the manufacturer does not always mention in the official documentation.

It's important to understand that Redmi 7 (codenamed onc) is based on a Qualcomm Snapdragon 632 processor and has a unique data partition structure that affects the reset process. For example, when using informal firmware, a standard reset through the menu may not clean all partitions completely. We'll look at not only the basic methods, but also alternatives for power users.

This article will be useful for both beginners and those who have experienced such procedures, and here you will find step-by-step instructions with visual cues, method tables and answers to frequent questions. We will focus on restoring IMEI after reset, a critical point for Redmi 7 that many forget.

1.When do I need to reset settings on Redmi 7?

Before you start a procedure, it's important to know if it's really necessary, and factory resets are radical solutions that should only be applied in certain cases, and here are the most common scenarios:

• 📱 Smartphones are slowing down or constantly overheating for no apparent reason
• 🔄 After updating MIUI Critical errors have appeared (e.g. com.android.phone stops working)
• 🔒 You forgot your graphical unlock key or password
• 📦 Preparing the device for sale or transfer to another user
• 🛠️ Eliminating the consequences of a failed rooting or custom firmware installation

However, resetting is not always a panacea, for example, if the problem is related to hardware malfunctions (a broken screen, a broken speaker, battery problems), then software reset will not help, and in some cases, it can make the situation worse, for example, when a damaged boot or system partitions.

⚠️ Note: On Redmi 7 with the unlocked bootloader, a reset via the standard menu can result in data loss in the persist section, which will cause problems with the bootloader. IMEI In this case, additional recovery is required through QCN-file.

2.Resetting preparation: what to do in advance

An unprepared reset can result in the loss of important data. Before you start the procedure, follow the following steps:

1. Back up all your important data. Redmi 7 can do this through Settings → Additional → Backup and Reset → Local Backup. Alternatively, use Mi Cloud or third-party apps like Titanium Backup (requires root).
2. Make sure the battery is at least 50% charged, and interrupting the discharge process can have serious consequences.
3. Remember or record your Mi Account information if it is linked to the device, and you may need confirmation after the reset.
4. Remove the memory card and SIM-If you have the cards installed, it will prevent random formatting.

Pay special attention to backup IMEI and NVRAM data. On Redmi 7, this data is stored in the persist section, which is not always correctly cleared during a standard reset. For reliability, we recommend using the MTK Droid Tools utility (for MediaTek processors) or QCN Rebuilder (for Qualcomm).

If you are planning a reset due to performance issues, try alternative methods first:

• 🧹 Clear the cache through Settings → Warehouse → Clear the cache
• 🔄 Update the firmware to the latest version MIUI
• 🚫 Turn off the autoload of unnecessary applications

3. Method 1: Reset via the settings menu (the safest)

This is the easiest and most recommended method for most users, it requires no special knowledge and is suitable if you have access to the menu of a smartphone.

Instructions:

1. Open Settings (the gear icon on the main screen).
2. Go to the About Phone section (usually at the bottom of the list).
3. Select Resetting (may be called Reset and Reset).
4. Tap Reset all settings (or "Reset to factory settings").
5. When a request appears, enter a password/pattern lock, if it is installed.
6. Confirm the action by clicking Reset the phone.

The process will take 5 to 15 minutes, and when it is completed, the device will automatically restart and prompt you to perform the initial setup, as after purchase.

⚠️ Attention: On some firmware MIUI After the reset, you may see a "This device is locked" error, which means that the device is tied to your Mi Account, and you will need to enter the username and password from the account that was linked to the reset to unlock the device.

💡

If Redmi 7 doesn't turn on after reset, try pressing the power button for 20-30 seconds. Sometimes the system needs to be forced to restart after factory settings.

Method 2: Reset via Recovery Mode (if the phone is not turned on)

If your smartphone doesn't respond to taps or is locked with a password, you can use Recovery Mode, a more complex method, but effective in critical situations.

Step-by-step:

1. Turn off Redmi 7 (press the power button for 10 seconds if it freezes).
2. Press the Power button + Volume Up button at the same time.
3. Hold them until the Mi logo appears and vibrations (usually 5-10 seconds).
4. Release the buttons and you will see the Recovery menu (in English or Chinese).
5. Use volume buttons for navigation and power button for selection.
6. Select Wipe Data (or Clear Data) and then Wipe All Data.
7. Confirm the action by selecting Confirm.
8. Once completed, select Reboot to reboot.

The Recovery menu on Redmi 7 may not have touch controls, just volume and power buttons. If you see a menu in Chinese, look at the location of the items: Wipe Data is usually the third or fourth item on top.

5. Method 3: Fastboot Reset (for power users)

This method is suitable if the first two did not work or you need to "deep" cleaning of all partitions, it involves the use of a computer and special utilities.

Tools required:

• 💻 Computer with OS Windows/Linux/macOS

4. Open the command line (or terminal) and execute the command: fastboot devices Make sure the device is identified (serial number should appear).
5. For reset, run fastboot erase userdata fastboot erase cache fastboot reboot

If you need a complete cleanup (including system and vendor), use:

fastboot erase system


fastboot erase vendor




fastboot erase product

Attention.

⚠️ Warning: On Redmi 7 with a locked boot loader, fastboot erase commands for system or boot partitions won't work. This is protection against unauthorized firmware changes.

💡

Fastboot reset is the most powerful method, but it requires caution. The wrong commands can turn a smartphone into a brick. Use only if you are confident in your actions or follow a proven instruction.

6.IMEI recovery after reset on Redmi 7
