Recovery Mode (Hard Reset) Reset Method
The fastest and least technically difficult way to remove a forgotten password is to use the built-in Recovery mode. This method does not require a connection to the computer and the use of additional software, since all the necessary functions are already built into the device’s memory. However, it is worth considering that this method only works if the phone does not include additional protection for the Mi Account account, which requires a password after reset.
To enter Recovery mode on Redmi 4A, you need to turn the device off completely, then you need to press the combination of the Up Volume and Power buttons at the same time.

However, if Find Device was previously activated on the device, the system will require you to enter a password from Mi Account or Google Account that was tied to the phone, a security measure that cannot be circumvented by a simple reset via Recovery.
Fastboot and Mi Flash Tool
If a standard reset fails or the device is locked by the account, the only solution is to completely reflash through Fastboot mode using a computer, which allows you to write a clean image of the system to the phone’s memory, completely ignoring the old security settings, and you will need to download the official Mi Flash Tool utility and unpack the archive with the firmware into the root of the disk so that the path does not contain Cyrillic characters.

Google Find My Device is only possible if the locked phone has the internet and geolocation enabled. You can send a command to reset remotely, but it will also result in the loss of all information. The good thing is that it doesn't require physical access to the device buttons if they're faulty.
Possible problems and solutions
When you flash or reset Redmi 4A, users often encounter a variety of bugs. One of the most common is the Missmatching image and device error in Mi Flash. It occurs when you try to install firmware from another model or region. For example, you can't flash the global version over the Chinese version without first unlocking the bootloader, and vice versa. Always check the firmware code name - for Redmi 4A it's prada.
Another common problem is hanging on the Mi logo after firmware. This may mean that the recording process has been interrupted or the wrong cleaning mode has been chosen. In this case, you need to repeat the firmware procedure, making sure that you have selected Clean all mode. If the phone enters an endless restart (bootloop), try pressing the Volume Up button and Power to log into Recovery and reset again.
Driver errors in Windows can also prevent a successful operation from being completed. If the Device Manager shows "Unknown Device" with a yellow exclamation point, you need to manually update the driver by pointing the path to the Xiaomi or Qualcomm driver folder. Without the correct driver, the computer will not be able to send commands to the phone bootloader.
⚠️ Warning: If after all the attempts the phone does not respond to buttons and does not charge, the bootloader or system partitions may be damaged, in this case, independent actions may be useless, and the help of specialists with a programmer will be required.

At this point, the system can again request input from the Google or Mi Account that was synced to the device before the reset. This is FRP (Factory Reset Protection) theft protection. You will need to enter exactly the login and password that was used on this phone before.
If you don't remember your Google account details, the setup process can become more difficult because it's officially impossible to bypass FRP. However, if you've completely reflashed your phone through Fastboot with all partitions cleared, the likelihood of requesting FRP is reduced, but not completely ruled out, since this binding is stored on Google servers. If you request Mi Account, the system will require a password from it if the "Device Search" function was active.
After completing the initial setup, it is recommended to immediately update the system through the Settings → About Phone → System Update.This will allow you to install the latest security patches and fix possible factory firmware bugs. Also remember to reconfigure biometric protection or set a new, more reliable password that you will definitely not forget.
