Owners of Xiaomi Redmi 4X smartphones often face the need to remove the device’s binding to the account, which may be necessary when selling the gadget, transferring it to another user or in the event of loss of access to the main mailbox. MIUI security system tightly binds the device to the account, which creates obstacles when reflashing or resetting settings to factory.
Ignoring the detachment procedure can lead to a locking of the device, known as Activation Lock. In this state, the smartphone turns into a “brick” available only for emergency calls. Understanding the mechanisms of operation of Xiaomi cloud services will help avoid data loss and functionality of the device.
In this article, we will discuss in detail all legal and technical ways to (unlock) bindings. You will learn how to log out correctly using standard methods and what to do if a standard login to the menu is impossible due to a forgotten password or a purchased used device with someone else's account.
Staff exit from the account through smartphone settings
The easiest and safest way to unplug Redmi 4X is to use the built-in settings menu, which works if you know your account password and have physical access to your unlocked smartphone screen. Before starting, make sure your device is connected to a stable Wi-Fi network or mobile internet.
To perform the operation, go to Settings, then select Accounts (or Mi Account). In the menu that opens, find the exit button. The system will require you to confirm the action with a password. This is protection against theft: even with a phone in your hands, an attacker will not be able to reset the binding without an access code.
Once the data is successfully entered, Xiaomi's server will send a command to remove the anchor. The smartphone will disconnect from the cloud, and the Find Device function will stop tracking the device's geolocation. It is important to exit through the menu, not just delete the account from the list of synchronized services, since this does not always completely remove the activation lock.
- 📱 Go to Settings. → Mi Account and click "Exit».
- 🔑 Enter the current password to confirm the removal of the binding.
- 🌐 Wait for a message about a successful disconnection from the servers.
- 🔄 Restart the device to apply changes.
If the phone requests the password again after rebooting when turned on, then the binding remains active, in which case you need to check the status of the device on the official website through the device management section.
☑️ Pre-reset check
Removing binding via i.mi.com web interface
An alternative method of managing binding is available via a browser on a computer or other smartphone. i.mi.com allows you to remotely manage a list of trusted devices, which is especially useful if the Redmi 4X phone itself is unstable, but logging in from another gadget is possible.
Sign in using your credentials. From the management menu, select Devices, which will show you a list of all the gadgets associated with your profile, search Redmi 4X and select the deletion or deletion option, and the system will warn you that the device will lose communication with the cloud.
⚠️ Note: Deleting a device via a web interface does not always remove the activation lock (FRP), If the phone itself is not logged out, this method is best used as an auxiliary or to clean the list of trusted devices.
Once you have done the work on the site, it is recommended to force the smartphone to restart, if it is connected to the Internet, the command to uncouple should synchronize, however, to fully guarantee the cleanliness of the device before selling, it is always better to perform a full reset (Wipe) only after leaving the account in the phone menu.
- 💻 Open your browser and go to i.mi.com.
- 🔐 Sign in to your Mi Account.
- 📱 Choose Redmi. 4X from the list of devices and click "Delete».
The web interface also lets you see when the device was last online.If the Redmi 4X hasn't connected to the network in a long time, the uninstall command will only be executed after its next Internet connection.
💡
If you are selling a phone, take a screenshot of the blank list of devices on i.mi.com after deleting it, which will prove to the buyer that the account is completely untied.
Resetting settings and the problem of blocking activation
Many users try to get around the problem by simply running Hard Reset through the Recovery menu. On modern versions of MIUI, this method without first logging out of the account will activate the protection. Once reset, the phone will require the username and password of the owner, without which further use is impossible.
Activation Lock is a theft protection mechanism, and if you bought a used Xiaomi Redmi 4X and you encountered a request, the previous owner didn't untie the device, and the only legal way is to contact the seller and ask them to delete the phone from their account remotely.
Attempts to flash a phone with a locked bootloader and active tethering are often futile. Server verification occurs every time you connect to the network, and Lost Mode status or simply having a tether will block the basic functions of the system.
| User action | Mi Account status | Post-reset result |
|---|---|---|
| Exit through settings | Untied. | Phone's clean, ready for sale. |
| Hard Reset (no exit) | Tie-in | Enabled Password Request (FRP) |
| Deletion of the account on the site | Partly untied | Password request possible when connecting to Wi-Fi |
| Flashing without unlocking | Tie-in | The lock is maintained, possible loss of functions |
It's important to distinguish between the lock screen password and the Mi Account password. Resetting the screen password over the receptacles is possible, but it won't help if you activate account protection. Critically, without the Mi Account password, it's almost impossible to legally unlock the device after the reset.
Restoring access with a forgotten password
If you are the legitimate owner of Redmi 4X and you have forgotten your password, you can restore the procedure. Go to account.xiaomi.com and select the option “Forgot your password”.
The most common is a linked phone number or backup email, a confirmation code will come to the contact, you can enter it, you can set a new password and then log into the phone's settings to detach. If the phone number is lost, the recovery process becomes complicated and may require you to contact the purchase checks in support.
In some cases, if two-factor authorization is enabled, you may need to confirm through a trusted device. Make sure that other of your Xiaomi gadgets are signed in to the same account.
- 📩 Go to the Xiaomi password recovery site.
- 📞 Enter the phone number or email associated with your account.
- 🔢 Receive and enter a confirmation code from SMS or mail.
- 🆕 Create a new password and save it.
After changing your password, wait 15-30 minutes before trying to log in to your phone.
What to do if your phone number is lost?
Technical aspects and work with IMEI
In the deep diagnosis or flashing Redmi 4X You often need access to an engineering menu or use special tools. IMEI-The device code is tightly linked to the Mi Account server base. IMEI (which is illegal in many countries) will not remove the account binding, since the verification is carried out by a unique device identifier and its certificates.
For repair professionals, the concept of “Unlock Bootloader” is used. Officially unlocking through miui.com/unlock requires a device to be linked to an account for 7 or 30 days. If an account is blocked or lost, official unlocking of the bootloader becomes impossible, which closes the way to install custom firmware.
Using paid services for “unlocking” (Bypass) is often temporary or requires soldering of memory chips, which may not be economically feasible for the Redmi 4X model. Bypass usually allows you to enter the menu, but does not give full access to the system and updates.
⚠️ Note: Using third-party software to reset your Mi Account (so-called "patches" or "activators") can cause your phone to be completely inoperable. MIUI Can lock the loader permanently.
If you are planning a major system change, always try to resolve the issue first through official password recovery, which will keep the warranty (if it is still valid) and the stability of the communication modules.
💡
Official bootloader unlocking and account resetting are only possible if you have access to an account, and workarounds do not give you full functionality of the device.
