Owning a Xiaomi smartphone involves using a proprietary ecosystem centered on a Mi Account, which is not just a profile for downloading apps, but a powerful device security tool that is tied to a unique device identifier. However, users often face the situation when you need to untie an account before selling a gadget or after buying a used device with already entered data from the previous owner.
The process of deleting an account on the Redmi Note 4 model has its own nuances, depending on whether you have access to a password or your phone is blocked by security. Wrong actions can lead to a complete locking of the device known as the Mi Cloud Lock, turning the smartphone into a useless brick. In this article, we will discuss in detail all legal and technical ways to solve this problem so that you can safely manage your gadget.
It is important to understand that MIUI security is constantly being improved, and simple bypassing methods that worked a few years ago may not be relevant today, so it is important to follow the current instructions adapted specifically for the Snapdragon processor architecture installed in the Redmi Note 4.
Why you need to unbundle your Mi Account
The main reason for deleting your account is to prepare your device for sale or transfer to another user. If you just reset your device without first decoupling, your smartphone will require you to enter your login and password when you first activate it, a security mechanism that prevents the use of stolen phones, but it creates problems for honest users who have forgotten their data.
The second common scenario is buying a used device, where new owners often find that the previous owner forgot to delete his profile, in which case the phone is useless until the old account is deactivated, sometimes deleting the account to solve problems with synchronization or changing the region of use of the device.
⚠️ Warning: Trying to buy a phone with a locked Mi Account to unlock is extremely risky, often with lost or stolen status, and it is impossible to legally untie them without the original owner’s involvement.
Deletion is also necessary if you are changing the main phone and want to completely clear the old Redmi Note 4 of personal information.Just uninstall the application is not enough, since the binding remains at the server and system files level. Only full deletion ensures that your photos, contacts and geolocation will not be available to the new user or will not interfere with his work.
Preparation for Account Deletion
Before you start any manipulation of system settings or service codes, you need to perform a series of preparatory steps, which minimizes the risk of losing important data and allows you to roll back changes in the event of an error. The first step should always be to back up all important information.
☑️ Checklist before deleting the account
Make sure that USB debugging is enabled on your device if you plan to use computer methods, although this is not always required for the standard procedure.It is also critical to know which version of the MIUI operating system is installed on your Redmi Note 4. On older versions (such as MIUI 8 or 9), the procedures may differ from the current MIUI 10-12 that can still be found on these devices.
If you have access to an account but you have forgotten your password, try to restore it through the official recovery page on Xiaomi's website. This is the easiest and most secure way. You will need access to your linked phone number or email. Without restoring access to these communications tools, the process can become much more complicated and require contacting for support.
💡
Take a picture of the device’s screen (MIUI version, build number) before you start any action, which will help you find the exact instructions if standard methods don’t work.
Standard method of removal through settings
If you have full access to the smartphone menu and you know the password, this is the right and safest method. It ensures that the device is properly unconnected from the manufacturer's servers, and the next time you turn on, there will be no activation request. First, go to the Settings menu of your Redmi Note 4.
In the list that opens, find the Mi Account section (usually at the top of the list or in the System and Device section). Clicking on it will take you to the profile management. You need to scroll to the bottom and find the exit or delete account button.
Once you press the exit button, the smartphone will request a password from the Mi Account. This is a mandatory security measure. Once you successfully enter the password, the device will send a request to the server, and the binding will be deleted. You will see a notification of successful exit. Now you can safely reset the data without fear of blocking.
| Action. | The way is on the menu | Data required |
|---|---|---|
| Entrance to profile | Settings → Mi Account | No. |
| Initiation of exit | "Out" button | No. |
| Confirmation | Password entry | Mi Account password |
| The result | Notification of success | No. |
It is important to note that if two-factor authorization is enabled on the device, the confirmation code may come in. SMS-Make sure that you're not in the same position. SIM-The card that's linked to the account is active and on the phone or other device so you can get the code quickly.
Delete your account without a password (through reset)
The situation where the password is lost is the most difficult. Xiaomi officially does not provide ways to circumvent the protection without confirming the identity of the owner. However, there are methods that allow you to reset the binding if the device has previously been synchronized. One of these methods is using the "Find device involves" function, but it only works if the phone is connected to the Internet.
If the phone is locked and requires an account when turned on (activation screen), standard menu methods are not used. In this case, some users resort to flashing the device. For Redmi Note 4 (codename nikel or mido), there is the possibility of installing global firmware through Fastboot mode, but this requires an unlocked bootloader.
⚠️ Note: Unlocking the bootloader is officially possible only through waiting for the time 7-168 hours after the application is submitted MIUI Unlock Tool: Using third-party paid services to unlock carries the risk of system damage.
There is also a method using an engineering menu and file swapping, but it requires a computer, special cables and in-depth knowledge of the field. ADB-For the average user, this can be too complicated and risky, and a mistake in one byte of a system file can cause the phone to stop loading at all.
Risks of using third-party software
Use of service codes and engineering menu
In some versions of the firmware MIUI There were vulnerabilities that allowed you to access hidden menus through a set of specific codes in a call, such as ##6484###, which opens an engineering menu, but you can't delete your account directly from there. SIM-maps or networks that may indirectly assist in restoring access to the SMS-code.
A popular but not always working method is to try activation via the language and region selection menu. If you switch languages quickly or use specific combinations of taps, older versions of MIUI could skip the greeting stage. On current versions, current for the Redmi Note 4 in 2026-2026, this method hardly works due to server checks.
If your phone supports the installation of a memory card, sometimes it helps to create a special trigger file at the root of the card, which, when inserted, can cause a failure in the process of checking your account. However, this is extremely rare and depends on the specific version of the Android security patch.
💡
Service codes are a diagnostic tool, not a magic wand; on modern versions of MIUI, they do not allow you to delete your Mi Account directly without a password.
What to do if the device is bought with a lock
If you purchase a Redmi Note 4 and encounter an activation screen that requires someone else’s account, your actions depend on the honesty of the seller.The ideal option is to contact them and ask them to remove the device from the trusted list through the i.mi.com web interface.
If the seller doesn't get in touch or says "did nothing," the situation gets complicated, you have to prove ownership of the device, which may require checks, a box with a matching IMEI or a sales contract, and you can try to contact an authorized Xiaomi service center.
Service staff can do a check on the device, and if the phone is not listed in the databases of lost or stolen, and you provide proof of purchase, they can help with unlocking, but service centers are not required to do this for free or even take software locks, because this is the responsibility of the user.
- 📞 Try to find the previous owner’s contacts through your call history if you have a phone call. SIM-map inside, there's a signal.
- 📦 Check the box and documents: serial number and IMEI The settings must be the same (if you can get there through the emergency menu).
- 🛡️ Be careful: if your phone is stolen, it can be locked remotely at any time, even after successfully unlocking it.
