Xiaomi Redmi Note 4X: how to roll back firmware to the factory version

Xiaomi Redmi Note 4X is one of the most legendary models of the budget segment, but time takes its toll, and modern versions of the MIUI shell can run on it unstable. Users often face situations when after an update the system begins to consume more power, interface artifacts appear or applications stop running correctly, in such cases, the only right decision is to return to an earlier, stable version of the operating system or a complete reset.

The process of rolling back the firmware requires carefulness and a clear follow-up to the algorithm of actions, since interference in the system partition carries certain risks. Restore the device in several ways: from a simple reset through the settings menu to deep flashing through the Fastboot mode. It is important to understand the difference between these methods to choose the best one for your current situation and level of technical training.

In this article, we will discuss in detail all available methods of returning the system to its original state, paying special attention to the nuances of working with the Redmi Note 4X. You will learn how to prepare the device, what tools will be required and how to avoid the typical errors that can turn a smartphone into a “brick.” It is critical before starting any actions to create a full backup of important data, since the rollback process is guaranteed to remove all user information from the internal drive.

Preparation of the device and selection of the rollback method

Before you start taking action, you need to do a lot of preparation, which will take longer than the firmware procedure itself. Data security is the number one priority, so the first step should always be to copy contacts, photos and documents to an external medium or to the cloud, and ignoring this step will lead to irretrievable loss of information, since rolling back the firmware involves formatting memory partitions.

Then you need to decide on the recovery method. If the smartphone is turned on and you can get into the settings menu, you will do the reset method through Recovery or the built-in reset function. If the device is running with critical errors or does not boot, you will need to use a computer and special utilities. Redmi Note 4X is characterized by high compatibility with custom recovery menus, which expands the user experience.

An important stage of preparation is to charge the battery. 60-70%, So that at a critical point in the system file record, the device doesn't turn off. USB-The cable is good and provides a stable connection, especially if you plan to use a computer.

Full Reset Method through Standard Recovery Menu

The easiest and safest way to roll back changes or fix software failures is to use the built-in recovery mode.This method does not require root rights or an unlocked bootloader, making it available to any Xiaomi Redmi Note 4X owner. To enter this mode, you need to turn off your smartphone and press the volume button and the power button simultaneously.

Once the Mi logo appears, you can release the power button by continuing to hold the volume until the menu appears with a black or blue background. The navigation is done with volume buttons, and the choice is confirmed by the power button. You need to find the Wipe Data or Wipe & Reset option, and then select the Wipe All Data option. The system will request confirmation of actions several times to prevent accidental start.

Once confirmed, the cleanup process will begin, which can take between seconds and a couple of minutes. Data formatting will affect all user partitions, returning the phone to the “out of the box” state. Once the process is complete, the device will suggest a reboot, after which the initial Android setup will begin, a method that is effective for removing viruses and correcting logical errors of the system.

⚠️ Note: If the device was enabled to search for the device (Mi Cloud or Google Find My Device), after the reset, the system will necessarily require you to enter a password from an account that was synced earlier. Forgetting this data means losing access to the smartphone forever.

Using custom Recovery TWRP for rollback

For more advanced users with an unlocked bootloader, TWRP Recovery is the ideal tool. This utility provides advanced memory partition management and allows you to make full system backups (Nandroid backup). If you have previously installed custom firmware or modified the system, it is through TWRP that it is easiest to return everything as it was just by restoring a saved copy.

To do a rollback, enter Recovery mode (usually by pressing the power button and increasing the volume when the device is off). In the main menu, select the Wipe option, then Advanced Wipe. Here you should note the Dalvik / ART Cache, Cache, System and Data sections. The Internal Storage section is not necessary if you want to save files, but for a clean rollback it is better to clean it, too, having made a backup.

Once the partitions are cleaned, you can go to install a stable firmware version. TWRP You select Install, and then you specify the path to the downloaded zip file with the firmware. TWRP It is faster and more reliable than standard means, as it minimizes the impact of system errors on the recording process. Cache/Dalvik before first loading.

Recoil through Fastboot mode and computer

If the software failure is so severe that the phone doesn’t boot even into Recovery mode, Fastboot mode comes to the rescue. This low-level protocol allows you to interact with the device directly through the computer, bypassing the operating system. For the Redmi Note 4X, this is often the only way to “revive” the device after unsuccessful software experiments.

To work with this method, you will need a PC with drivers installed ADB And Fastboot, and the original firmware in.tgz (not.zip). Download the official Mi Flash Tool, which automatically recognizes the connected device. The phone is converted to Fastboot mode by pressing the volume button and connecting. USB-computer-cable.

In the Mi Flash Tool, you need to choose the path to unpacked firmware and the firmware mode. For a full rollback, you should choose the Clean all option, which will completely clear the memory and install the clean system. Avoid the Clean all and lock option if you are not 100% sure of the firmware region, since blocking the bootloader with the firmware in the wrong region will make it impossible to boot the device.

💡

Use it. USB-port 2.0 on the computer motherboard, not on the front of the case. USB 3.0 sometimes cause connection stability issues when firmware is running older Xiaomi models.

Common mistakes and ways to solve them

The firmware rollback process rarely goes perfectly smoothly, especially on devices with a history of several years of use. One of the common problems is the error of checking the signature when installed through standard Recovery. The system can write "Can't verify update" or "Update package is corrupted." This means that you try to install the version of the software below what it is now using an upgrade method that does not allow it.

In this case, you either need to unlock the bootloader or use the Fastboot mode, which does not check the version when installing through the Mi Flash Tool. Also, users experience a freeze on the Mi or Android logo after reset. If waiting 15-20 minutes does not help, the procedure should be repeated, paying special attention to cleaning the Dalvik Cache partition.

Another common situation is the lack of network connection or the incorrect operation of communication modules after rollback, this is solved by re-flashing the modem firmware or resetting the network settings, and hardware resets can be done by typing the code # #4636## in the phone and selecting the corresponding menu item if the phone responds to commands at all.

⚠️ WARNING: When running through Fastboot, never turn off the cable. USB And don't interrupt the process, even if the progress bar is in place, interrupting the system partition recording can cause damage to the bootloader, which will require soldering the programmer to recover.
