Owning a budget smartphone like the Xiaomi Redmi 5A is often accompanied by a complete data cleanup before selling or after buying the device with hands. However, if the previous owner did not log out of his profile, the new owner faces an activation lock known as FRP (Factory Reset Protection), a security system designed to protect the ownerโs data in the event of theft, but often becomes an obstacle for legal users who have forgotten the password or bought the device โhandโ.
The process of unlocking Xiaomi Redmi 5A requires careful approach, as the wrong actions can lead to complete inoperability of the gadget. There are several methods of bypassing protection, from official restoration of access to the use of engineering menus and specialized software. The choice of the specific method depends on the version of the Android operating system and the level of download MIUI.
In this article, we will discuss the technical details of the procedure, explain the difference between resetting a password and completely untethering the device from the servers, you will learn what tools will be required to successfully complete the operation and how to avoid the typical errors that can turn a phone into a brick.
Reasons for blocking and the essence of FRP protection
FRP (Google Factory Reset Protection) protection and binding to Mi Account are two layers of security that are often confused. In Xiaomi devices, the Mi Account lock is deeper and is tied to the unique device identifier on the manufacturer's servers. If you reset to the factory settings (Wipe Data) without first logging out of the profile, the next time you turn on, the system will require you to enter a password from the account that was last active on that device.
The main reason for this is buying a used phone. Unscrupulous sellers often forget to untie the gadget or the device could have been stolen. In the latter case, unlocking is legally questionable, but for honest users who have forgotten their data, this is the only way to bring the phone back to life. Server lock does not allow the phone to be used in full, limiting the ability to install applications and set up the system.
It's important to understand that simply manipulating the volume and power buttons won't help remove protection. The system stores the account hash amount in a protected partition of memory that doesn't erase in a normal reset, which is why you need to use special login methods to the service menu or flash it with changing system files.
โ ๏ธ Note: If the device is listed in the database of stolen IMEI, Software unlocking may not help, as the server lock will remain active even after the firmware change.
There is a myth that flashing the global version of MIUI into Chinese or vice versa removes the lock. It is not. Account binding does not depend on the regional version of the firmware, since it is tied to a unique device ID and server authorization.
Preparation for the Redmi 5A Unlocking Procedure
Before you start active, you need to have a stable working environment, the process of removing protection can take from 15 minutes to several hours, depending on the method chosen. USB-cable and computer with Windows operating system, as most utilities for working with Qualcomm processors (which are in Redmi) 5A) They only work in this environment.
You will need to charge the smartphone battery to a minimum of 60-70%. interruption of the process of firmware or writing system files due to battery discharge is guaranteed to cause the board to fail, you should also install the necessary drivers for ADB and Fastboot modes, as well as Qualcomm HS-USB QDLoader 9008 drivers.
โ๏ธ Preparation for unlocking
Some methods may require access to an engineering menu (Engineer Mode) through a special codeset in the Phone app or through a special codeset. ADB-If the phone is locked on the welcome screen and it doesn't let you on the menu, that option will be dropped and you'll have to use mode. EDL (Emergency Download Mode).
Don't forget to check the Android and MIUI version if you have any access to the system. You can do this from the Settings โ About Phone menu. This depends on the choice of the specific firmware version or method of bypassing. For Redmi 5A, Android 7.1 and 8.1 with MIUI 9, 10 or 11 shells are relevant.
Recovery Mode (Official Way) Reset Method
The easiest, but often the least effective, way is to reset the system through recovery mode, which only works if you remember the data from your account, or if your phone wasn't tightly tied to the verification server. To log into Recovery Mode on a phone that's off, press both the power button and the volume button.
When the Mi logo comes up, release the power button, but keep the volume up. You'll be taken to a multi-point menu, controlled by the volume button and selected by the power button. You'll select Wipe Data, then Wipe All Data, and confirm the action. After you complete the process, select Reboot.
If after the reboot, the system again requests the password from the Mi Account, then the FRP protection is active, and a simple reset did not help. In this case, the account data is stored in the persist or frp section, which is not cleared by the standard procedure. Further attempts to enter the password can temporarily lock the device for 24 hours, so do not try to guess the combinations at random.
โ ๏ธ Attention: Repeated incorrect password entry can lead to knob locking of the device from the servers of Xiaomi, after which it can be unlocked only through the service center with a check of purchase.
Some users try to exploit security holes in older versions of MIUI by going into the date and time settings or calling Google Assistant through the feature menu, but on current firmware versions, these vulnerabilities are most often closed by security patches.
Use of EDL mode and Mi Flash program
Regime. EDL (Emergency Download Mode is a deep level of access to a device based on Qualcomm processors, which includes Redmi. 5A. Entry into this mode is possible when the phone is turned off by simultaneously clamping both volume buttons and connecting USB-The screen is black, but the Windows Device Manager will have a Qualcomm device. HS-USB QDLoader 9008.
For firmware in this mode, the official Xiaomi Mi Flash Tool is used. You will need to download the archive with firmware (Fastboot version, extension.tgz) specifically for your model (codename rgo for Redmi 5A). After unpacking the archive and running the program, select the path to the firmware folder, press the Flash button and wait for the process to end.
However, there is a caveat: newer versions of MIUI often require an authorized Mi Account with service center permissions to run through EDL, and without that authorization, the utility will give you an error, and you can get around this by using modified versions of the sewers or temporarily soldering (Test Point method), which requires soldering and opening skills.
What is Test Point?
If you donโt have an authorized account, you can try the โemptyโ firmware method or use third-party utilities that exploit vulnerabilities in the sahara protocol (Qualcommโs download protocol), but this already requires more technical knowledge.
FRP bypass through engineering menu and ADB
The most effective software method for Redmi 5A With Android versions up to 8.1, it is often the use of vulnerabilities in the configuration interface. The essence of the method is to use a special feature menu or voice assistant to call the browser or Wi-Fi settings, and then download APK-dumper FRP. One of the popular ways is to use a key combination to call the keyboard and go to settings.
If you can get into the Wi-Fi settings, you can try adding a new network. A long string of characters or a special code is entered in the Network Name Field (SSID) that causes the buffer to overflow or go to the menu. Then, through the Share or Print menu, you can try to start the browser and download the FRP Bypass APK file. After installing this application, you can access the settings of Google accounts and delete sync.
Alternatively, use ADB (Android Debug Bridge) if the phone previously had USB debugging enabled. the adb shell am start -n com.google.android.gsf.login/ command can start the login process, which sometimes allows you to bypass the lock screen.
adb shell content insert --uri content://settings/global --bind name:s:user_setup_complete --bind value:s:1This method doesnโt delete an account, but it can trick the system into thinking that the initial setup has already been completed, but on Redmi 5A with MIUI 10 and higher, this method rarely works because of the systemโs enhanced security.
What worked on MIUI 9 may not work on MIUI 11, so always check the software version before you start manipulating it.
Comparison of methods and risk table
The choice of unlocking method depends on your technical skills and the state of the device. Below is a comparison table that will help you assess the risks and complexity of each method. Remember that a software reset always carries the risk of data loss, and using unverified software can lead to infection of the computer.
| Method | Difficulty | Risk of data loss | The need for a PC | Efficiency |
|---|---|---|---|---|
| Recovery Mode | Low. | 100% | No. | Low (if you forget your password) |
| Mi Flash (EDL) | Tall. | 100% | Yes. | High (requires authorization) |
| ADB Commands | Medium | No. | Yes. | Medium (depending on the version of the software) |
| Service centre | Low. | Yes. | No. | 100% (officially) |
As you can see from the table, the most reliable, but paid way is to contact an authorized service center Xiaomi, where specialists can officially untie the device from the account upon presentation of documents confirming ownership (check, box, warranty card).
Using paid IMEI unlock services is also an option, but it requires transferring your deviceโs unique identifier to third parties, which is not always secure.
โ ๏ธ Warning: Never give your Mi Account password to anyone or suspicious websites that promise "instant unlock" is a direct route to identity theft.
If you decide to act on your own, always start with the least risky methods. Trying to reflash the phone over an EDL without experience can lead to the fact that the device will no longer be determined by the computer at all, and only the soldering of the memory chip will help.
Prevention of blockages and conclusions
To avoid future Mi Account problems, always follow the correct sequence of steps before selling or dropping your phone. The first step is to log out of all your accounts: Google, Mi, and remove screen lock, and then you can do Wipe Data.

Always link the phone number and backup email to your Mi Account, which will allow you to restore access to the device through the phone. SMS-code, even if you have forgotten your primary password.
It is also recommended to periodically check the list of trusted devices in the security settings of the account on i.mi.com. If you see unfamiliar devices or old models that are no longer in use, delete them, which will not only secure the account, but also prevent confusion in future resale of gadgets.
In conclusion, the Xiaomi Redmi 5A is a reliable device, but its security system requires respect. Unlocking from the Mi Account is possible, but requires technical knowledge and caution. If you are not confident in your abilities, it is better to contact professionals to avoid aggravating the situation.
