Despite its age, the Xiaomi Redmi 4A remains a popular device that often requires flashing to restore or change the regional version. The process of installing software through Fastboot mode is the most reliable method to completely clear the memory and return the device to factory condition. Unlike an air upgrade, this method gives full control over the system parts and allows you to correct critical boot errors.
To perform this procedure, you will need a computer running the Windows operating system, which is serviceable. USB-It's important to understand that any manipulation of the system partition carries risks, so following the algorithm of actions is a prerequisite for success. If you're ready to take responsibility, you can start preparing the workplace.
Preparing the working environment and downloading files
The first step is to download all the necessary components, without which the firmware process is impossible. You need a special utility MiFlash Tool, which acts as an intermediary between the computer and the smartphone. You also need to download the firmware itself for the Redmi 4A model (codenamed uggee or prada depending on the revision), making sure that it is labeled as Fastboot, not Recovery.
The critical point is to install the correct Qualcomm and ADB drivers. Without them, the computer simply won’t see the device in bootloader mode, and MiFlash will show an empty list of connected gadgets. Often users face a problem when the device is identified as an unknown device, which is solved by manually installing drivers through Device Manager.
Where to find the right firmware?
Once you have downloaded all the files, create a folder on the C root disk with a short name, such as mi, and unpack the firmware archive there. The path to the files should not contain Cyrillic characters or spaces, as this can cause an error in the script installer.
Installation of drivers and configuration of MiFlash
Start the MiFlash installer and follow the installation wizard's instructions. After the installation is complete, don't start the program immediately, but start with the drivers first. The folder with the installed program often contains a driver or MiUSBDriver file that you need to install into the system.
If the automatic installation didn't work, you'll have to manually operate through Device Manager. Connect your phone in Fastboot mode (clamping the volume down and USB button) and find the device with a yellow exclamation point. Update the driver by pointing the path to the Qualcomm or Xiaomi folder inside the program directory.
💡
Use the original. USB-Cheap charging cables often do not provide stable data transfer, which leads to failures when writing memory sectors.
When the drivers are installed, run MiFlash on behalf of the administrator. In the program interface, press the refresh button. If done correctly, a line will appear in the list with the serial number of your device, which means that the communication between the PC and the smartphone is established correctly.
Fastboot Mode Entering Redmi 4A
To go into firmware mode, you need to turn off your smartphone completely. After you turn off, press and hold the Volume Down button. USB-cable connected to a computer.
The device should display the distinctive Mi Bunny logo repairing the robot and the FASTBOOT label in orange. If the screen remains black, try pressing the power button together with the volume for 10-15 seconds to restart, then repeat the procedure.
⚠️ Attention: If the phone vibrates but the screen doesn't light up, there may be a problem with the display plume or the matrix itself. USB, to ensure that it is operational.
Make sure the battery is at least 50-60% charged, the process of writing system partitions is energy intensive, and a sudden power outage in the middle of the procedure can lead to irreversible consequences for the memory controller.
The process of firmware through MiFlash Tool
Open MiFlash and press select. In the window that opens, find the folder where you previously unpacked your firmware files. It's important to choose the root folder where the images file is located, not the image folder itself.
At the bottom of the program window, you'll see three firmware mode options. To clean your data completely and eliminate all errors, select Clean All mode, which completely erases user data and partitions, installing a clean system.
☑️ Checklist before launch
Once you select the mode, press the flash button, and the recording process will start, which will take 200 to 600 seconds, during which time the progress bar will be filled with green, and the log will be filled with messages about the passage of stages.
Analysis of possible errors and fault codes
There may be various errors that interrupt the procedure, and there is a frequent error called "Miss matching image and phone", which means that the bootloader version is not compatible with the firmware, and this is solved by downloading a newer or older version of the software.
Another common problem is the error "Flash all except data and storage" or connection timeout. USB-port, faulty cable or driver conflict. Try switching the cable to port USB 2.0, located directly on the motherboard (back of the system unit).
| Error code | Description of the problem | Method of decision |
|---|---|---|
| 0x80070005 | Denied access | Run MiFlash on behalf of the administrator |
| 0xe0016008 | Checksum verification error | Download the firmware, the file is damaged |
| 0xe0010201 | No device found. | Check drivers and USB cable |
| Anti-rollback error | Attempted rollback version | You cannot run the version below the current one. |
If you see an error with the Anti-rollback, you are trying to install an older version of Android than the one that was there before, and the manufacturer is blocking such actions for security reasons, and you can not get around this with standard methods.
Completion of procedure and first launch
Successful firmware completion will be marked by flash done in the program window and green status. The device will automatically restart. The first launch after a complete clean (clean all) can take up to 10-15 minutes.
Don't panic if you see the Mi logo for a long time. The system performs initial app optimization and partition setup. If the phone doesn't turn on after 20 minutes, try to force the reboot by holding the power button for 15 seconds.
Once the desktop is available, it is recommended to check the build version in the About Phone menu immediately and make sure the version number matches the downloaded file. Now your Redmi 4A is ready for active use again.
