Account management on Xiaomi smartphones, especially on flagship models like the Mi 9, is a critical aspect of digital security and usability. Many users face the need to untie their profile from the device before selling, transferring the gadget to another person or simply to resolve software conflicts. The process of leaving Google Account on the shell of MIUI has its own nuances that distinguish it from standard Android.
Incorrect session termination can lead to locking the device with FRP (Factory Reset Protection), which will make the phone unusable without entering the password of the previous owner. So it is important to clearly understand the difference between simply logging out of services and completely deleting an account from the device’s memory. In this article, we will discuss in detail all the safe methods of breaking communication between your device and the search giant’s servers.
We will look at the standard system tools, methods of forced reset through the developer menu and methods of bypassing locks if access to the phone is lost. Particular attention will be paid to the features of the MIUI 10, 11 and 12, which are often installed on the Xiaomi Mi 9 at different times in its life cycle. Proper execution of instructions ensures that your personal data will remain safe and the new owner will not get access to your correspondence or photos.
Why you should leave your Google account on Xiaomi
The main reason for this procedure is to prepare the smartphone for resale or transfer to another user. If you just reset the settings to the factory without performing the preliminary exit, the FRP protection mechanism will work. This means that once turned on, the new owner will see a welcome screen requiring the username and password of the account that was synchronized last, without this data, the phone will turn into a “brick”.
The second important reason is to fix synchronization problems, and it often happens that Google Services is not working properly, such as notifications stop coming, contacts stop loading, or a permanent login error, in which case full logout and re-sign-in allow access tokens to be updated and all services to work normally.
⚠️ Note: If you plan to sell a phone, be sure to make sure the device is connected to the Internet at the time of logging out.The server must receive a signal about the disconnection, otherwise the lock may remain active even after the reset.
Also, logging out is necessary when changing your primary mailbox. Some Xiaomi and Google system apps can be tightly tied to a specific profile, and changing a user without first untiing can cause chaos in cloud storage. Deleting an account on Xiaomi Mi 9 completely erases local copies of emails, contacts and calendar associated with that profile, so make sure you have a backup.
Preparation of the device before the unbundling of the profile
Before you start manipulating accounts, you need to perform a number of preparatory steps, which will help to avoid loss of important data and ensure the successful completion of the operation. First of all, check the presence of an active Internet connection. For stable operation, you should use a Wi-Fi network, since mobile Internet can be unstable in the process of transferring data to authentication servers.
The second step is to back up your data. Even if you plan to reset completely, make sure your photos, contacts and documents are saved in the cloud or on your computer. MIUI has a built-in backup tool that you should also use. Go to the settings section and select Advanced Settings, then Restore and Reset.
☑️ Checklist of preparation for exit from the account
The third important thing is to disable two-factor authentication or prepare confirmation codes if they are required to sign in from new devices. Although codes are usually not needed when exiting, they may be needed if the system suspects suspicious activity and requires re-authorization during the cleanup process.
Standard method of exit through system settings
The safest and most appropriate way to unplug an account is to use the Android Settings menu, which ensures that all service files are deleted correctly and that Google servers receive a notification that the device is no longer associated with your profile.
Find a section that may be called “Accounts and Sync” or simply “Users and Accounts”, depending on the version of MIUI. In the list you will see all the added profiles: Mi Account, Google, WhatsApp and others. Click on the desired Gmail email address. The profile management menu will open, where you will select the option “Delete Account” or “Sign out”.
The system will request confirmation of action and possibly a screen unlock password or a pattern lock, which is a security measure to prevent unauthorized users from deleting data, and once confirmed, a cleanup process will begin that will take a few seconds, and the device can freeze for a short time — that's normal, and local databases are being removed.
- 📱 Open “Settings” and go to the “Accounts” section».
- 🔍 Select from the list your Google profile that you need to delete.
- 🗑️ Click the “More” button (three dots) and select “Delete Account».
- ✅ Confirm the action by entering the password of the lock screen.
💡
If you have multiple Google accounts on your phone, delete them sequentially, starting with the secondary ones. The primary account that Play Market is registered to is best deleted last.
Using a Developer Menu to Reset FRP
In some cases, standard output may not be possible due to software errors or forgotten passwords, which can be used to help with hidden system features. Developer menu in Xiaomi Mi 9 allows you to manage debugging over USB and other options that can help to circumvent some restrictions, although for direct deletion of Google account it is used rarely, more often to reset network settings.
To activate this mode, you need to go to About Phone and quickly click on the MIUI build number seven times. Once the notification "You became a developer" appears, you can go to advanced settings. Here it is important to be careful: changing the wrong settings can disrupt the system. We are interested in the item "Debugging by USB", which sometimes requires you to enable for the use of specialized PC tools.
There's a network reset method that often helps if your account is stuck, and you need to reset your Wi-Fi and mobile Internet in the developer menu or standard network settings, and it won't delete your account directly, but it can break your current sync sessions, allowing you to delete your profile in a regular way.
⚠️ Warning: Do not turn on the option «OEM-unlock" in the developer menu, unless you plan to flash the device. MIUI activation of this item may result in a bootloader lock or data reset without the possibility of recovery.
What is FRP and how does it work?
Solving Account Deletion Problems
Xiaomi Mi 9 users often experience a situation where the delete button is inactive or disappears immediately after clicking, this can occur if the account is used by system applications or if access rights are limited by the device's security policy (for example, if the phone is corporate), in which case you need to check the list of applications with administrator rights.
Go to the security settings and find the Device Administrator Apps section, if there are unknown programs or job profiles that block changes, they need to be deactivated, only after that the system will allow you to delete the main Google account, and the problem may lie in the unstable operation of the Google Play Services service.
Try clearing the cache and data of the Google Play Services service itself before trying to exit. To do this, go to Apps, search the list of Google Play Services, select Memory, and click Clear All Data. After restarting your phone, try again to exit through the standard menu.
| Problem. | Probable cause | Method of decision |
|---|---|---|
| The Remove button is inactive | Administrator rights | Disable rights in security settings |
| Synchronization error at the exit | Bad Internet or service failure | Clear the Google Play Services cache |
| Requires a password that doesn’t fit | Password change recently | Restoring access through the browser to the PC |
| The account returns after the reboot | MIUI system error | Delete your account in safe mode |
Alternative methods and reset via Recovery
If you don’t have access to the settings menu (forgot your pattern lock or password), the only option is a full reset via Recovery Mode. However, it’s important to understand that on modern versions of Android and MIUI, this method does not delete your Google account from the FRP protection memory.
Turn off your phone completely to enter Recovery. Then press both the power button and the volume button. Hold them until the Mi logo appears, then release the power, while keeping the volume up. In the menu that appears, select the language (if available) and the "Wipe Data" -> "Wipe All Data" option.
This method is only useful if you remember data from your Google account and just want to reset your phone to the “out-of-store” state to then re-enter the password, but if the goal is to bypass security, standard Recovery will not help, it will require more complex manipulation of the engineering menu or paid services, which is beyond safe use.
💡
Hard Reset via Recovery does not remove Google FRP protection; it only deletes user files, but the account binding remains at the server and bootloader level.
