How to completely remove Mi Account with Xiaomi Redmi 4X: from unlock to bypass protection

Xiaomi Redmi 4X remains a popular budget smartphone even years after its release, but many users are faced with the problem of a tied Mi Account. Według statistics, about 30% of owners of used devices can not unlock the phone due to a forgotten password or previous owner. This article will help to remove Mi Account from Redmi 4X without the risk of a “brick”, using both official methods and workarounds.

The main challenge is that Xiaomi is actively protecting its devices from unauthorized access. After a Hard Reset, the phone requires you to enter your associated account data — this is a standard feature of Find Device. We will analyze all the current ways from official unlock through support to technical bypasses using ADB and Fastboot.

Why you can’t just reset your settings to Redmi 4X

Many users mistakenly believe that Wipe Data in Recovery mode will clean the phone completely. In practice, after this procedure, Redmi 4X requests Mi Account data, which was previously linked, this is due to the work of the Mi Cloud Activation Lock function, analogous to Apple's iCloud Lock.

Technically, the lock is implemented through:

• 🔒 Hardware identifier IMEI, account-bound
• 📱 Encrypted section /data memory
• 🌐 Server Verification at the First Internet Connection

Even if you bought the phone with your hands and the previous owner made a reset, the system still requires you to enter a login and password from his account. The only exceptions are devices officially unlocked through account.xiaomi.com.

Official way: unlocking through Xiaomi support

The safest method is to contact Xiaomi Support with proof of ownership of the device.

1. Go to the account unlocking page
2. Select "Device locked after reset"
3. Download scans of documents (check, boxes with IMEI, warranty card)
4. Specify the IMEI of the device (you can find it on the sticker under the battery or in Settings → About the phone)

The term of consideration of the application is from 3 to 7 working days.

• 📄 Original documents on the phone
• 📅 Purchase dates (if more than 2 years have passed, the chances are lower)
• 🌍 Region of purchase (for devices from China the procedure is more complicated)

💡

If you still have the original Redmi 4X box, take a picture of the IMEI sticker and serial number to speed up the support check.

Once you approve the application, you will receive an email with instructions to unlock, and in most cases, it will be enough to enter a temporary code generated by the system.

Method 2: Bypass Mi Account via Fastboot mode (for firmware up to MIUI 10)

This method only works on Redmi 4X with firmware older than MIUI 10 (Android 7.1). For newer versions, it is not relevant due to the increased protection.

• 💻 Windows computer 7/10
• 🔌 USB-cable (original or high quality)
• 🛠️ Mi Flash Tool and Qualcomm Drivers
• 📱 Fastboot firmware ROM for Redmi 4X (version 8.4.26 or lower)

Step-by-step:

1. Turn off the phone and press Volume Down + Power to log into the Fastboot.
2. Connect the device to your PC and start MiFlash.exe.
3. In the program, click Select and specify the path to the unpacked firmware.
4. Select Clean All Mode (important! Not Clean All and Lock)
5. Press Flash and wait for the process to complete (5-10 minutes).

After flashing the phone will boot up without linking to the Mi Account, but note that:

⚠️ Attention: This method will only work on old firmware. MIUI 11/12 And it'll call up the Anti-Rollback protection, and the phone will turn into a brick".

Method 3: Using Mi Account vulnerability (MIUI 9-11)

For MIUI 9-11 firmware, there is a workaround through ADB based on a vulnerability in the authentication process.

• 🔧 Initiated Debugging Mode USB (If the phone is not blocked yet)
• 💻 PC with installation ADB Tools
• 📱 Access to Wi-Fi or mobile network on your phone

Instructions:

1. Connect your phone to your PC and log in to ADB: Adb devices (should appear serial numbered device)
2. Follow the command to bypass the check: adb shell content insert --uri content://settings/secure --bind name:s:user_setup_complete --bind value:s:1
3. Reboot the device: adb reboot

If done correctly, the phone will skip the Mi Account input screen after the reboot and suggest that the device be configured as new, which works because the command simulates the completion of the initial setup.

Method 4: Unblocking through service centers (paid option)

If independent methods did not help, you can contact specialized service centers. the cost of the service varies from 1000 to 3000 rubles depending on:

Advantages of the service method:

• 🔧 Guarantee of results (with successful diagnosis)
• 🛡️ Minimum risk of “bricking” the device
• 📱 Ability to save user data (in some cases)

But there are pitfalls:

⚠️ Note: Some services use unofficial unlock methods that may result in a lock IMEI. Before contacting, check whether they give a guarantee for the operation of the network after the procedure.

Method 5: Alternative firmware (LineageOS, Pixel Experience)

Installing custom firmware is a radical but effective way to bypass Mi Account, and Redmi 4X (codename santoni) is available for:

• 📱 LineageOS (Android 10/11)
• 📱 Pixel Experience (Pure Android)
• 📱 Havoc-OS (with advanced settings)

The installation will require:

1. Unlock the bootloader through Mi Unlock Tool (you need a Xiaomi account that is not tied to the device!).
2. Install TWRP Recovery for Santoni.
3. Swipe custom firmware and GApps (if you need Google services).

Advantages of the method:

• 🚀 Complete removal of all traces of the original firmware and Mi Account
• 🔄 Possibility of updates through OTA
• 🛡️ No connection to Xiaomi servers

Disadvantages:

• ⚠️ Loss of official guarantee
• 🔋 Possible problems with the battery (incorrect charge accounting)
• 📶 Unstable operation of the module NFC (assemblies)

💡

Installing custom firmware is the only method that is guaranteed to delete the Mi Account permanently, but requires technical skills and risks voiding the warranty.

What to do if nothing helps: extreme measures

If all of these methods do not work, there are two options:

1. Sale of the phone "as is": At sites like Avito or Yula, there is a demand for blocked Redmi 4X - they are bought for spare parts or unlock through specialized services. The average price of such a device is 1500-2500 rubles.
2. Chip-off (eMMC flashing): Extreme method, in which the phone is removed from the EMMC memory chip and reflashed on the programmer. Cost - from 3000 rubles, the risk of damage to the board - ~ 10%.

Before you go to extreme measures, check:

• 🔍 Do you have any old backups with passwords (check Google Password Manager)
• 📧 Letters from Xiaomi in the mail (possibly there are unlock codes there)
• 🤝 Contact with previous owner (if the phone is purchased by hand)
