Changing the owner of a smartphone or preparing the device for sale always poses a challenge to the user to completely clean up personal data. Owners of Xiaomi Redmi 9 should understand that simply removing photos or contacts is not enough to ensure privacy. The key step is to properly disable accounts, since Android security system and MIUI shell are closely linked to cloud services.
If you ignore the detachment procedure, the new owner will face a block on activation, and you risk losing access to your photos and notes after the reset. The deactivation process requires sequential actions in the settings menu to avoid errors. In this article, we will discuss in detail the algorithm of actions that will allow you to safely delete your Mi Account and Google profile.
It's worth noting that modern versions of Android have built-in anti-theft mechanisms, so the "just reset to factory settings" approach without prior preparation can lead to backfires known as FRP lock. We'll look at all the nuances so you can be sure of the cleanliness of the device.
Preparing the device for deletion of profiles
Before proceeding to deactivate your account directly, a number of preparatory steps must be taken to ensure that your data is kept safe and the system is stable during the change process, and make sure that the Redmi 9 battery is at least 50-60%, as the synchronization and deletion process can consume energy.
An important step is to back up all of your important information, and you can use Mi Cloud tools or third-party solutions to transfer data to your computer, and once you delete your account, all of the information that is stored in the cloud and not synced locally may become unavailable.
⚠️ Note: If you are planning to sell your phone, be sure to pull it out. SIM-microSD card and memory card before any manipulation of the software part.
It is also recommended to check for active subscriptions or linked payment methods in the Google Play store. Deleting your account from your phone does not automatically cancel subscriptions, so it is better to manage them through the web interface or the settings of the app store itself in advance.
Delete Mi Account on Redmi 9
The centerpiece of Xiaomi’s ecosystem is the Mi Account, which syncs contacts, theme, notes, and location of the device. To remove it, you need to go to the settings section, which displays the current login status, usually this path looks like Settings → Mi Account or through the top menu of the notification curtain.
Once logged in, the system will request proof of identity, a mandatory MIUI security measure to prevent unauthorized access to your data by unauthorized persons, and you will need to enter the password you set up when you registered or the confirmation code that came via SMS.
☑️ Check before deleting your Mi Account
In the menu that opens, scroll down to the "Get Out" or "Delete Account" button. The system will again warn you that the data will be deleted from the device. Confirm the action, and the phone will execute the detachment command. Then, at the top of the settings menu, again the prompt to log in or register will appear.
Google Account Unbundling and Synchronization
In addition to the manufacturer’s services, it is critical to remove Google profile, as it is the key to the basic features of Android. To do this, go to the Settings menu → Accounts and Sync → Google.
Select the desired email address. In the menu that opens, click on the button "Delete account" or "More" → Delete your account. The system will warn you that all messages, contacts and other data associated with that account will be deleted from your phone.This will not affect data stored in the Google cloud, but local copies will disappear.
If there are multiple profiles on the device, the procedure must be repeated for each of them.Having at least one active Google account after resetting may trigger a FRP request the next time a new user activates the phone.
| Data data | Local removal | Keeping in the cloud | Risk of loss |
|---|---|---|---|
| Contacts | Yes. | Yes (in synchronization) | Low. |
| Photos | Yes. | Yes (Google Photo) | Medium. |
| Passwords. | Yes. | Yes (Google Smart Lock) | Low. |
| MIUI notes | Yes. | Only in the Mi Cloud | High-pitched |
Resetting settings to factory state
Once all accounts are successfully deleted, you can proceed to a full reset, which will return Redmi 9 to the state it was in immediately after purchase. Go to Settings → About Phone → Reset or search by settings by entering Reset.
In the reset menu, select the option "Clear all data." The system will require you to enter the screen unlock password or a pattern lock to confirm the operation. This is protection against accidental reset if the phone is in the wrong hands while the screen is unlocked.
The phone will warn you that all files, applications and settings will be destroyed, and once confirmed, the formatting process will begin, which can take 5 to 15 minutes depending on the storage capacity, during which time the device can restart several times.
⚠️ Warning: Interrupting the reset process (battery discharge or mechanical shutdown) may cause file system damage and inability to boot the OS.
FRP protection issues and their solution
FRP (Factory Reset Protection) is a security mechanism that requires you to enter a password from the last used Google account after you reset. If you forgot to delete the account before resetting, the phone will request this data when you first set up, and this is done to protect against theft.
In the case of this situation on Xiaomi Redmi 9, there is no standard way to circumvent a request without a password.The only legal way is to recall login details or restore access to an account through a computer.
If you bought a phone with your hands and it requests someone else’s account, it means that the previous owner did not follow the detachment procedure, in which case you need to contact the seller to remotely remove the device from his trusted list or obtain a password.
