Account management on smartphones Xiaomi i Redmi is a critical aspect of the security and usability of the device. Owners are often faced with the need to unlink an old profile before selling a gadget or solve an access problem after purchasing a used device. Incorrect actions in this process can lead to the device being blocked by the protection system FRP (Factory Reset Protection), which will turn the phone into a “brick” for the average user.
There are several methods for performing this procedure, each of which depends on the current state of access to the settings menu. If you know the password and have access to the system, the process takes a couple of minutes. However, if the device is blocked or purchased second-hand, the algorithm of actions changes radically and requires deeper intervention in the system Android.
In this article we will analyze in detail all possible scenarios: from standard removal through the menu to complex manipulations with service codes and utilities. Particular attention will be paid to the nuances of the operation of the shell MIUI and HyperOS, which have their own unique protection features. Understanding these mechanisms will allow you to avoid common mistakes and maintain control over your device.
Regular account deletion through Android settings
The safest and most correct way to unlink a profile is to use the built-in functions of the operating system. This method is suitable if you have full access to the menu Settings and you remember the screen unlock password. Before starting the procedure, make sure that the device is connected to a stable network Wi-Fi or mobile data, since the system needs to synchronize changes with Google servers.
The process begins by going to the account management section. The path may differ slightly depending on the version MIUI, but the logic remains the same. You need to find the item responsible for synchronization and accounts, where all connected services are displayed. Select the desired email address from the list.
After selecting a profile, the synchronization menu will open. Here it is important not just to delete data, but to delete the account itself from the device. Clicking the delete button initiates the process of clearing local data and unlinking the device from security servers. This action will prevent you from asking for a password after resetting your settings.
Before deleting your account, be sure to fully sync your contacts and photos to avoid losing important data stored in the cloud.
It is worth noting that deleting an account does not erase personal files such as photos, videos or installed applications. However, all data associated with this profile (contacts, notes, calendar) will no longer be updated on the device. If the phone has several profiles, the procedure must be repeated for each of them.
Using Factory Reset for a complete wipe
The full reset function, or Factory Resetreturns the smartphone Redmi to its factory state. This is a radical method that deletes all user data, applications and settings. The main purpose of using this method in the context of our topic is to prepare the device for sale or transfer to another user without access to your personal information.
You can perform a reset through the settings menu or through recovery mode Recovery. In the settings menu, the path usually looks like Settings → About phone → Reset settings. The system will warn you that all data will be destroyed. If the Google account was deleted correctly (as described in the previous section), the phone will not ask for a password after rebooting.
☑️ Preparing for a hard reset
If you reset without first deleting your Google account, the protection system will work FRP. When activated for the first time, the phone will require you to enter the password for the last synchronized account. This is an anti-theft mechanism that cannot be bypassed by simply pressing buttons. Therefore, the sequence of actions (first deleting the account, then resetting) is critical.
⚠️ Attention: After performing a Factory Reset, it will be impossible to restore deleted photos and messages without a previously created backup copy. Make sure that all important files are saved on external media or in cloud storage.
In Recovery mode, the reset is performed using a combination of buttons when the phone is turned off (usually Volume Up + Power). This method is useful if the Android system does not boot or is unstable. However, the risk of accidental data loss is higher here, since warnings are displayed in English and require attention.
Reset via service codes and engineering menu
For advanced users and repair specialists, there are reset methods via the engineering menu or service codes. On devices Xiaomi this functionality is often limited compared to other brands, but certain commands can help diagnose and clean some sections. One of these codes is ##778##, which opens the testing menu.
In the engineering menu you can find options to reset the radio module settings or clear certain memory sections. However, using these features requires extreme caution. Incorrect settings in the engineering menu can lead to loss of network signal or unstable operation of the phone. A standard Google account reset through this menu is not directly performed, but you can clear Google Play services data.
To clear Google services data through the app menu, you need to go to Settings → Applications → All applications. Find "Google Play Services" and "Google Play Store" in the list. In the menu of each application, select "Memory" and click "Clear data" and "Clear cache".
| System component | Action | Result |
|---|---|---|
| Google Play Market | Clearing data | Resetting store settings, updating the list of applications |
| Google Play Services | Clearing data | Resetting synchronization, possible exit account |
| Google Accounts | Clear data | Delete authorization cache |
| Google Settings | Clear data | Reset preferences services |
This method is useful if the account is frozen and cannot be deleted in the standard way. After clearing the data of all Google-related components, it is recommended to restart the device and check the list of accounts in the settings. Often, after such a procedure, the profile becomes available for deletion.
Bypassing FRP lock on Xiaomi and Redmi
The situation when the phone is locked by the FRP system is one of the most difficult. This happens if the previous owner did not log out of the account before the reset. On modern versions Android and shells MIUI / HyperOS security holes close quickly, so there is no universal instruction for all occasions.
One of the common methods involves using TalkBack or special applications to access the browser and Wi-Fi settings. The essence of the method is to call up the keyboard or browser through the voice assistant or accessibility menu, download the necessary APK files and install the application for resetting passwords. However, this method requires precise access to the interface, which is constantly changing.
Risks of using third-party apps
Using unofficial utilities to reset FRP (for example, MI Unlock Tool bypassing the rules, Bypass APK) carries the risk of infecting the device with viruses or third parties gaining full access to your data. In addition, such actions may violate the terms of the warranty.
There are also paid services and unlocking boxes that use vulnerabilities in the bootloader Bootloader. To use them, you often need to officially unlock the bootloader, which is impossible without access to your Mi account. This creates a vicious circle, which can only be broken by an official service center with a purchase receipt.
⚠️ Attention: Buying phones second-hand without checking for a linked Google account is a high risk. If the seller claims that they "forgot the password", the phone is most likely stolen or found. It is almost impossible to legally restore access without the owner's data.
If you bought a phone with FRP lock, the only legal way to unlock it is to provide proof of purchase (receipt, warranty card) to an authorized service center Xiaomi. Employees can remove the block after checking the IMEI code of the device with the database.
Deleting a Mi account in conjunction with Google
On smartphones Xiaomi i Redmi Google account is often closely linked to the account Mi Account. The security system requires you to log out of both profiles before performing a factory reset. Ignoring this rule will lead to double blocking: in addition to Google FRP, Mi Cloud Lock will also work.
To delete your Mi account, go to Settings → Mi Account. At the bottom of the screen there will be a "Logout" button. The system will require you to enter your Mi account password. After a successful logout, the device will be unlinked from the Mi cloud and the Find My Device function will be deactivated.
It is important to understand the difference between these two types of accounts. Google account is responsible for access to the Play store, mail and contacts. Mi account manages Xiaomi cloud storage, theme and device search. Both protection mechanisms work independently, but block access to the system upon reset.
Double sign-out rule: Before selling your Xiaomi phone, be sure to sign out of both your Google account and your Mi account. Only this guarantees complete clearing of the device from locks.
If you have forgotten your Mi account password, you can recover it through the i.mi.com website using the linked phone number or backup email. Without restoring access to the Mi account, it will not be possible to perform a full reset with clearing data - the phone will require authorization every time you try to enter the menu.
Frequently asked questions (FAQ)
What should I do if the phone asks for a password for an account that I have already deleted?
This may occur due to a synchronization delay. Try connecting to the same Wi-Fi network from which you performed the deletion and wait 10-15 minutes. If this does not help, it is possible that the deletion was incorrect and the binding remains on the server. In this case, log into your account from your computer through the Google browser, find your device in the list and forcefully delete it from there.
Is it possible to reset your Google account without losing photos and contacts?
Yes, if you simply delete your account through the settings menu (Settings → Accounts), your data will not be deleted. They remain on Google's servers. However, if you do a Factory Reset, all local data will be destroyed. Before resetting, make sure that synchronization is enabled and the data is uploaded to the cloud.
Will the lock work if I just remove the SIM card before resetting?
No, removing the SIM card does not affect the linking of the Google account. The FRP lock is tied to the device itself (IMEI) and the last entered Google account, regardless of the presence of a SIM card or Internet access at the time of reset. When you activate it for the first time, the phone will still require you to connect to the network and enter a password.
How can you find out if the phone is linked to someone else's account when purchasing?
When you turn on a new (for you) phone, carefully watch the welcome screen. If, after selecting a language and connecting to Wi-Fi, the “Account verification” or “Enter your Google account password” prompt appears, it means that the phone was not unlinked by the previous owner. Require the seller to completely log out of all accounts in front of you.
Does the Android version affect the reset procedure?
Yes, it does. There were more FRP bypass vulnerabilities on Android 10 and below. On Android 11, 12, 13 and 14 (as well as HyperOS), protection is significantly enhanced. Methods that worked a couple of years ago may not be relevant now. Always check that the information is up to date for your specific software version.
