How to completely demolish the system on Xiaomi Redmi 7: 3 working ways with nuances

Resetting the Xiaomi Redmi 7 to factory settings is a procedure that can be required in a variety of situations, from preparing the device for sale to eliminating critical system failures. However, the phrase “demolition” is often understood by users in different ways: someone means a regular reset through settings, and someone – a complete firmware reflash with unlocking the bootloader and installing custom software. In this article, we will analyze all possible scenarios, including nuances that are not written in the standard instructions.

without turning the phone into a brick.

It is important to understand that a full reset deletes all data without the possibility of recovery (unless you have a backup), but the good news is that Redmi 7 can reset even if:

• 🔐 Forgotten pattern lock or password;
• 🤖 The system is not loaded (hung on the logo) MI);
• 🔄 Delete the previous owner’s Mi Account;
• 🛠️ You need to flash custom firmware (for example, Pixel Experience).

1.Reset preparation: what to do before the procedure begins

The first rule when working with Xiaomi is never to start a reset unless you are sure about the battery. If the phone runs out during the procedure, the risk of getting a broken device increases significantly. The minimum battery charge before reset is 50% (optimal - 70-80%). This is due to the fact that in Recovery or Fastboot mode the energy consumption is higher than in normal mode.

The second is backup, and even if you plan to reset through the settings menu, there's always a chance something will go wrong. Use the official Mi Cloud or third-party solutions like Titanium Backup.

• 📱 Contact and SMS (export to.vcf and.xml);
• 📷 Photo and video (copy on PC or external drive);
• 🎮 Game savers (use Helium or manual backup);
• 🔑 Wi-Fi passwords (save the list of networks in a text file).

⚠️ Note: If the phone has enabled data encryption (optional in Settings) → Additionally. → Encryption, reset via Recovery may take up to 1-2 Don't interrupt the process, even if the screen goes out, wait for the restart.

The third step is to check that the bootloader is unlocked, and if you're planning to install custom firmware, the bootloader needs to be unlocked, and you can check this with the command:

adb reboot bootloader

After rebooting in Fastboot, type:

fastboot oem device-info

If the answer is Device unlocked: true, the bootloader is unlocked. If false, you will need an official unlock procedure through the Mi Unlock Tool (more on this below).

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

This is a method that works if the phone turns on and you can log in. It doesn't require unlocking the bootloader and it's suitable for most users. MIUI 10/11/12/13/14:

1. Open the Settings. → The phone.
2. Tap 7 times on the MIUI version to activate the developer mode.
3. Return to the main settings menu and select Additional → Reset.
4. Click Delete all data and confirm the action.

It takes 5-15 minutes, and after the restart, you'll be asked to set the phone up as new, and if you have a "failed to reset" error at this point, the reasons may be:

• 🔌 Unstable power supply (connect charging);
• 🔒 The boot loader is blocked (unlocking is required);
• 🛠️ System partition damaged (reset via Recovery needed).

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

If the Redmi 7 is stuck on the logo, reboots cyclically or does not respond to touch, resetting through recovery mode will help. This device uses Stock Recovery (factory), so no additional firmware needs to be installed.

To enter Recovery:

1. Turn off the phone (press the power button for 10 seconds).
2. Press Volume Up + Power and hold for 10-15 seconds until the Mi logo appears.
3. Release the buttons and you will see a menu in Chinese/English.

Recovery is controlled by volume buttons (up/down, move, power, select). Select Wipe Data (or Chinese), then confirm the action. Once completed, select Reboot.

⚠️ Note: If the error "E:unknown volume for path" appears in Recovery, it means that the system partition is corrupted. In this case, you will need to firmware through Fastboot (method 3).

The Redmi 7 has one feature: if you have previously installed the TWRP (Custom recaveri, the entrance to it is carried out by a combination of Volume up + Food, but you need to hold it longer (up to 20 seconds). TWRP Reset is performed via the Wipe point → Format Data.

Method 3: Complete Fastboot reset (for power users)

This method is used if:

• 🔧 You need to sew stock or custom firmware;
• 🔒 The bootloader is locked and other methods do not work;
• 🛠️ The system is so damaged that even the Recovery is not loaded.

The work will require:

• 💻 Computer with Windows/Linux;
• 🔌 Cable USB Type-C (original);
• 🛠️ Mi Flash Tool and the Mi Flash Tool ADB/Fastboot;
• 📦 Firmware for Redmi 7 (download from the official website of Xiaomi or Xiaomi Firmware Updater).

Step-by-step:

1. Unpack the firmware in a folder without Cyrillic characters (for example, C:\redmi7_firmware).
2. Install Xiaomi drivers and run the Mi Flash Tool.
3. Transfer the phone to Fastboot mode: adb reboot bootloader Or manually: Press Volume Down + Power for 10 seconds.
4. In Mi Flash Tool, click Select, specify the firmware folder, then Refresh (should appear) COM-port).
5. Select firmware mode: Clean all – full reset (recommended); Clean all and lock – reset + lock the bootloader (if you need to return the phone to factory state).

If the phone doesn't turn on after you've run through Fastboot, try clamping Volume Up + Power for 30 seconds for a forced reboot.If that doesn't help, repeat the firmware with the Clean all and lock option option option option option.

5. Unlock the bootloader on Redmi 7: when necessary

If you plan to install custom firmware (LineageOS, Pixel Experience), kernels or modified Recovery, the bootloader must be unlocked. On Xiaomi, this is done through the official Mi Unlock Tool utility, but there are nuances:

Requirements for unlocking:

• 📱 Mi Account (account must be older than 30 days);
• 🔗 The phone must be connected to this account in the settings;
• 🔌 Included debugging by USB and unlock OEM (Settings → For developers);
• 💻 Windows computer (the utility does not work on the computer) macOS/Linux).

The unlocking process:

1. Download Mi Unlock Tool from the official website.
2. Sign in to the utility under the same account as on the phone.
3. Transfer the phone to Fastboot and connect to the PC.
4. Press Unlock in the program and wait until it is completed (usually 10-30 seconds).

⚠️ Warning: Once the bootloader is unlocked, all data on the phone will be deleted and the warranty (if it is still valid) will be canceled. MIUI (Mi Pay or Game Turbo may not work properly.

If the utility gives an error "Couldn't unlock. Wait for 72/168/360 hours", it means that Xiaomi has imposed a temporary lock.

• Connect your phone to another Mi Account (if any).
• Try using another version of the Mi Unlock Tool (e.g. 5.5.223.24).
• Wait until the time is set (usually 72 hours) and try again.

💡

Unlocking the bootloader on Xiaomi Redmi 7 is possible only 1 time in 30 days for one Mi Account. If you sell the phone, it is better to leave the bootloader locked - the new owner will be able to unlock it yourself.

6. Frequent errors and their solutions

Even when following the instructions, Redmi 7 users often face problems.

Error 1: The phone doesn’t go out of Fastboot mode

If the device is constantly restarted to Fastboot after firmware, the reasons may be as follows:

• 🔌 Incorrectly selected firmware (for example, for Redmi Note 7 instead of Redmi 7);
• 🛠️ Boot or recovery section damaged;
• 🔒 The bootloader is blocked, but custom software is sewn.

Solution: Flush the stock firmware through the Mi Flash Tool with the Clean all and lock option.

Error 2: Reset requires an old password

If you reset your phone through Recovery, but after turning it on, it asks you to enter a password from your previous Mi Account, it means that the FRP (Factory Reset Protection) security mechanism has been activated to bypass it:

1. Connect your phone to Wi-Fi;
2. At the stage of entering the password, press Forgot the password?
3. Enter the account details that were linked to the phone;
4. If your account is not yours, contact the previous owner for the data.

Mistake 3: Cannot Switch Custom Recovery (TWRP)

On the Redmi 7 with MIUI 12+, the TWRP installation may be blocked due to the anti-rollback mechanism.

• Use a special version of TWRP for onc (e.g. from XDA Developers)
• Turn off signature verification in the TWRP settings (Settings → Disable DM-Verity)
• Sweep the patch. disable_forceencrypt disable forced encryption.

7.What to do after resetting: setup and optimization

After the successful reset of the Redmi 7, you will have to make an initial setup.

1. disable unnecessary MIUI functions:

• 📊 Settings → Battery → Energy Saving Mode (Select Balanced);
• 🔕 Settings → Notifications → Notification panel (disable unnecessary icons);
• 📱 Settings → Screen. → System animation (install) 0.5x speed up).

2. Update the firmware:

Even if you've stitched through the stock version, check for updates in Settings → About Phone → System Update. On Redmi 7, the latest official version of MIUI is 12.5.7 (Android 10). If you want a newer OS, consider custom firmware based on Android 11/12.

3. Restore the data:

If you have backed up through Mi Cloud, log in to your account and select Restore from the Settings menu.

• 📁 Copy files from the PC back to the phone;
• 📞 Import contacts from a.vcf file;
• 🎮 Install games and restore saves via Google Play Games or Helium.

4. Check the performance:

After reset, the Redmi 7 may run faster, but the lags will come back over time.

• 🚫 Limit the background activity of applications (Settings) → Annexes → Permits → Auto-start);
• 🧹 Clean the cache regularly (Settings) → Warehouse → Clean up);
• 🔄 Turn off automatic app updates on Google Play.

💡

After reset, take your time to install all the applications at once, start with the basics and observe the stability of the work for 2-3 days, which will help to identify "heavy" programs that can slow down the system.
