Xiaomi smartphone owners often face a situation where the device is locked after resetting settings, requiring authorization in a previously used profile. 3S, The question of "how to unload my account" becomes critical when buying a used gadget or restoring access after a forgotten password. FRP (Factory Reset Protection is designed to protect the data of the owner, but often becomes an obstacle for the legitimate user.
The process of de-association can range from simple password input to complex software manipulation and test modes. In this article, we will discuss all legal and technical ways of unlocking, focusing on the specifics of the Snapdragon 430 processor installed in this model. Understanding the nature of the lock is the first step to successfully solving the problem without losing functionality of the device.
It should be noted that the methods of bypassing protection depend on the version of the installed MIUI firmware and the level of access to the phone menu. If the device is in working condition and you remember the login data, the procedure takes a few minutes. However, if access is lost completely, you will need a deeper knowledge of the work of the Bootloader bootloader and specialized utilities to interact with the hardware of the smartphone.
Checking the blocking status and preparing data
Before you start active reset actions, you need to accurately determine the current state of the security system. On Redmi 3S, the binding indication may not be obvious, especially if the previous owner simply logged out of the account but did not untie the device remotely. Mi Account status is checked through the system settings, which displays the username and the device search activation status.
It is important to understand the difference between simply logging out of a profile and completely removing a device from the cloud trusted list. If a smartphone was reset to the factory settings (Wipe Data) without prior decoupling, the first time it downloads it will ask for a password. Ignoring this step or trying to guess the combination will repeatedly lead to a temporary blocking of the input ability, which will greatly complicate the recovery procedure.
⚠️ Warning: Repeatedly incorrectly entering a password can activate a lock timer for 24 hours or lead to a full account lock by Xiaomi security service.
To successfully complete the work, you will need a stable Internet connection, since the authorization servers must confirm your actions in real time. USB-cables, because cheap wires often cause connection breaks at a critical point in data memory writing.
Standard method of detachment through smartphone settings
If you have physical access to the MIUI work interface and you know the password from your account, the most reliable way is to use a regular unblocking procedure. This method ensures that after resetting the phone will not go into lock mode. Go to Settings → Mi Account and select the option to delete the profile from the current device.
The system will request identity verification by sending the code to the linked number or email. Once successful, the server will be synchronized and the device status will change to “Not Found” in the cloud list, only after that, it is recommended to perform a full reset (Wipe & Reset), if necessary.
- 📱 Open the Security or Settings app on the home screen.
- 🔑 Click on “Mi Account” and enter a password to confirm your identity.
- 🗑️ Select “Delete Account” or “Sign Out” by confirming the action in the window that appears.
- 🔄 Perform a reset to factory settings via the recovery menu or system settings.
Feature of Redmi 3S There are two slots available. SIM-The card, and sometimes the confirmation code comes to the SIM card that's not the primary one for the calls, so make sure both cards are active and accept the signal if you're using two-factor authorization.
💡
Before resetting the settings, be sure to remove SD-map SIM-maps to avoid accidental formatting of external media or loss of contacts.
Use of service menu and codes for resetting
For advanced users, there is a method of using an engineering menu that allows access to hidden testing functions. Qualcomm processors that are equipped with Redmi 3S often use the input of special combinations in the dialing field. However, in newer versions of MIUI, many codes are blocked, so this method should be considered as an auxiliary method.
One of the working options for some firmware versions is to call the test menu using the code ##6484##. Once you get into the CIT menu, you can check the modules, but there is no direct reset function, but having access to this menu indicates that the system is not completely locked at the backup level.
It is more effective to use ADB-commands, if the phone was previously enabled debugging USB. By connecting the device to a PC, you can try to delete the system files responsible for checking the account, although on modern security patches this rarely gives an instant result without superuser rights.
adb shell pm clear com.miui.cloudserviceThis command cleans the cloud service data, which in some older versions of MIUI allowed you to bypass the welcome screen, type it into the command line of a computer with Platform Tools installed, pre-connecting the smartphone.
⚠️ Attention: Use ADB-An error in syntax can lead to unstable system operation or cyclic reboot).
Unlocking through Fastboot and PCBA Test
Redmi 3S is based on the Snapdragon platform, which opens up the possibility of using low-level boot protocols. Fastboot mode allows you to interact with the memory partitions of the phone directly, bypassing the operating system. To enter this mode, you need to turn off the phone and pinch the key combination Volume Down + Power before the Fastboot logo with a hare.
There is a specific PCBA test method that sometimes bypasses the account check on older versions of software, which interrupts the loading process of the nanostage, causing the system to skip the authorization step, but requires high reaction speed and accurate timing.
Technical details of entering the PCBA Test
A more reliable option for this model is to use specialized FRP reset utilities such as MI Unlock Tool (official) or third-party scripts running through Fastboot. Unlock Bootloader is the cleanest way, but requires a wait of 168 hours (7 days) after the account is linked to the device.
- ⏳ Register on the forum MIUI and apply for unlocking.
- 🔗 Link the account in the developer settings (Settings) → The phone. → 7 times on the version MIUI).
- 💻 Run the official Mi Unlock utility on your computer and follow the instructions.
- ⏰ Wait for the waiting timer to expire (3 to 30 days).
After successfully unlocking the bootloader, you get full control of the device and can install custom recavers (TWRP), through which any system restrictions, including the binding of the Mi Account, are easily removed.
💡
Official unlocking of the bootloader is the only guaranteed safe method that does not violate the warranty (if it is still valid) and does not carry the risk of turning the phone into a “brick”.
Comparison of discharge methods: efficiency table
The choice of the right method depends on your technical background and the specific situation. Below is a comparison of the basic methods that are applicable to Redmi 3S, taking into account their complexity and risks.
| Method | Skills required | Risk of data loss | Efficiency at MIUI 10+ |
|---|---|---|---|
| State exit | Low. | No (no reset) | 100% |
| ADB team | Medium. | High-pitched | Low (10%) |
| Unlocking the loader | High-pitched | Yes (full reset) | 100% |
| Service codes | Medium. | Medium. | Very low (5%) |
As can be seen from the table, for modern versions of firmware (MIUI 10, 11, 12) the most effective method is the official unlock or professional reset through service centers that have access to authorized accounts.
Using questionable hacking software often results in malware installation or system partitioning shutdowns, boot and recovery. Always check the source of the downloaded utilities and read other users' reviews before running executable files on your computer.
☑️ Checklist before the start of work
Possible errors and ways to eliminate them
During the unlock process, Redmi 3S users often encounter typical errors, one of the most common being an Error 6002 or an Error 10007 when trying to unlock a bootloader, which usually indicate problems with the authorization server or incorrectly entered credentials.
If Mi Unlock doesn’t see your phone in Fastboot mode, check the drivers installed. Qualcomm devices often require manual driver installation through Windows Device Manager, choosing the Android Bootloader Interface model. USB-port, preferably USB 2.0, as older ports are sometimes more stable with engineering software.
⚠️ Warning: If the phone went into an endless bootloop after a failed reset attempt, don't panic. + Powering) and making Wipe Data.
In case nothing helps and the phone is locked forever, there is the option of flashing through EDL (Emergency Download Mode) mode. For Redmi 3S this often requires opening the back cover and closing test points on the board, since the bootloader can be locked at the processor level.
