Xiaomi Device Formatting: A Complete Reset and Cleanup Guide

Xiaomi device formatting is a procedure that can be required in a variety of situations, from preparing a gadget for sale to fixing software failures. However, an incorrect reset can turn a smartphone into a “brick”, and improper memory cleaning can irrevocably delete important data. In this article, we will analyze all the official and hidden formatting methods, including hard reset via Fastboot, firmware recovery through the Mi Flash Tool, and the nuances of working with Mi TVs and Xiaomi Routers.

Many users confuse the terms “setting reset”, “memory formatting” and “firmware”: the first returns the device to a factory state, the second completely cleans the data partition (including photos and applications), and the third implies reinstallation of the operating system. We will analyze each scenario in detail, specify the risks and give checklists for safe preparation, and pay special attention to models with a locked bootloader (Redmi Note 10 Pro, POCO X3 Pro, etc.), where improper actions can lead to the loss of IMEI.

Preparation for formatting: what to do before the dump

Before you click Reset, make sure you don't lose critical data. Even if Xiaomi's device malfunctions, there's a chance to save the information.

✅ Backup. Use the built-in Mi Cloud app (for contacts, notes, SMS) Or third-party tools like Titanium Backup (requires root), for media files, Google Photos or physical copying on a PC through the Internet is suitable. MTP-protocol.

✅ Check the Mi Account binding. After the reset, the device may require you to enter a login/password from the account that was on it before. If you do not remember the data, unblock the account in advance at account.xiaomi.com.

✅ Make sure you charge the battery. You can reset 30 percent of the charge through the menu, but if you plan to use the Fastboot or Mi Flash Tool, the battery should be at least 70 percent charged.

⚠️

Note: On models with a locked bootloader (for example, Xiaomi 12T or Redmi K50), a reset via Fastboot without unlocking will lead to a Mi Account authorization requirement. If you do not remember the account details, the device will become unusable.

Save IMEI (dial *#06# and write down the number)| Untie Google Account (Settings → Accounts)| Remove SIM and memory card (if not needed)| Connect to charging (for long-term operations)| Check for original cable (for Fastboot)

2. Ways to reset settings on Xiaomi smartphones

There are three official methods of resetting Xiaomi smartphones, varying in complexity and consequences. The choice depends on the state of the device: whether it works, whether the settings menu is available, and whether you have a PC at hand.

📱 Method 1: Reset via the settings menu (the safest way to do so)

1. Open Settings → About the phone → Reset settings.
2. Select "Delete all data" (on some firmware - "Erase all data and reset settings").
3. Enter. PIN-code or pattern lock, if requested.
4. Confirm the action and wait for the reboot (it will take 5-15 minutes).

🔧 Method 2: Hard Recovery Reset (if the phone doesn't turn on)

1. Turn off the device.
2. Press the Power button + Volume up until the Mi logo appears.
3. From the Recovery menu, select the language, then Wipe Data → Wipe All Data.
4. Confirm the action and wait until the end (do not turn off the device!).

💻 Method 3: Fastboot Reset (for power users)

1. Install Android SDK Platform-Tools on your PC.
2. Connect the off smartphone to the PC by clamping Volume down + Power (Fastboot mode).
3. Fastboot flashing unlock fastboot erase userdata fastboot erase cache fastboot reboot

⚠️

Note: On models with dynamic memory (Xiaomi 13 Ultra, Redmi Note 12 Pro+), a reset via Fastboot can result in the loss of part of the built-in storage.

3. Memory Formatting: Complete Cleaning of Internal Storage

If the goal is not just to reset, but to completely erase all data (including photos, videos, and installed apps), a deeper procedure will be required.

🗃️ For partition devices /data (majority)

1. Go to Recovery (as in Method 2 above).
2. Select Wipe Data → Format Data (this erases the /data partition completely, not just the user settings).
3. Confirm the action by entering Yes.

🔄 For devices with dynamic memory (UFS 3.1/4.0)

The new flagships (Xiaomi 14, Redmi K70 Pro) use dynamic memory allocation technology, where /data and /user are combined.

4. Formatting Mi TV and Mi Box TVs

Xiaomi TVs and consoles also support resetting, but the process is different from smartphones.The main difference is the lack of Fastboot mode, so all manipulation is carried out through menus or service button combinations.

On Xiaomi TVs, the reset does not remove firmware updates. If the goal is to roll back to the old version, you will need manual firmware via USB.

5. Xiaomi router formatting: resetting to factory settings

Xiaomi routers (Mi Router 4A, AX3600, AIoT Router AC2350) support two types of reset: soft (saves firmware) and hard (full reset with clearing of Wi-Fi settings and passwords).

🔄 Soft reset (via web interface):

• 📧 Try to restore access to your account via account.xiaomi.com (you will need a linked email or phone).
• 📄 If your account is not yours (the device is purchased from hand) – ask the seller for data or contact Xiaomi with a check.
• 💰 In extreme cases, use paid unlock services (risk of fraud!)

📱 Loss of loss IMEI post-formatted:

On some models (Redmi 9A, POCO M3), after resetting through the Fastboot, the IMEI may disappear.

1. Download the original NVRAM archive for your model (see 4PDA or XDA forums).
2. Fly it through the SP Flash Tool (for MediaTek processors) or QFil (for Qualcomm).

On models with Qualcomm Snapdragon 8 Gen 2 processor (such as Xiaomi 13), IMEI recovery is possible only through an authorized service center.

7. Frequent mistakes and how to avoid them

Even experienced users sometimes make mistakes when formatting Xiaomi. TOP-5 Failures and ways to prevent them:

🚫 Error 1: Resetting without detachment of Google account

If Factory Reset Protection (FRP) was enabled on the device, it will require data input from the last Google account after the reset. Solution: delete your Settings → Accounts → Google account before the reset.

🚫 Mistake 2: Using unofficial firmware

Firmware custom ROM (LineageOS, Pixel Experience) without unlocking the bootloader leads to a "hard brick." Solution: always check the status of the bootloader with the command:

fastboot flashing get_unlock_ability

🚫 Error 3: Interrupting the formatting process

If you take out the battery or turn off power during Wipe Data, the /data partition can be damaged.Solution: Use a PC Uninterruptible Power Supply (UPS) when working with Fastboot.

🚫 Error 4: Formatting a memory card as an internal memory card

On some devices (Redmi Note 8 Pro), microSD can be formatted as internal memory. Once reset, the data on it will be lost! Solution: before reset, remove the card or format it as portable in Settings → Memory.

🚫 Error 5: Incompatible version of the Mi Flash Tool

Using the old version of the firmware utility for new models (Xiaomi 12S Ultra) leads to the error "Flash is not done." Solution: always download the latest version from the official website.

💡

Before any formatting, check the device model on the GSMArena website. Some devices (such as the POCO F5) have unique reset instructions that are different from the standard ones for Xiaomi.
