After receiving the next MIUI update, smartphone owners often face unexpected problems: the device can start to run slower, discharge faster or show errors in the application. For the Redmi Note 8 T, this situation is especially relevant, as switching to new versions of Android sometimes negatively affects the optimization of old but reliable components.
Returning to the previous version of the operating system, or downgrade, is an effective solution to restore stability to the gadget. However, this process requires carefulness and careful follow-up to the instructions to avoid turning the phone into a brick. In this article, we will discuss all the available methods, necessary tools and precautions.
Before you start taking action, it's important to understand that any firmware experiment carries risks. A complete downgrade reset is a must, so storing important information on an external medium is the first step. Below are proven methods to help bring the device back to life.
Preparation for system rollback and backup
Starting the process with careful preparation, as rolling back the Android version on Xiaomi means completely erasing user data. Ignoring this stage will lead to loss of contacts, photos and application settings without the possibility of recovery.
The second critical step is to ensure a stable power supply: the battery must be charged at least 60-70%, and it is best to connect the device to the network during the entire procedure.
You will also need to download the original firmware file of the earlier version you plan to return to, and you can find it on official forums or specialized resources, making sure that the version corresponds to your region (Global, EU, Russia).
☑️ Preparation for the downgrade
Don't forget to check your device model. There are different modifications to the Redmi Note 8 T (codenamed ginkgo) and installing an inappropriate firmware may block the bootloader.
Recoiling method through the MIUI update menu
The easiest and safest way to return an old version of the system is to use the built-in update functionality, which does not require a connection to a computer and complex manipulation of the command line, but it only works under certain conditions.
To start, copy the downloaded firmware file (.zip format) to the root folder of the phone's internal memory. Then go to the settings menu, select About Phone and click on the MIUI version. In the window that opens, click three dots in the upper right corner and select the option "Select firmware file".
⚠️ Note: If the system sends a message that the file cannot be installed, it means blocking the downgrade.In this case, the standard method will not work, and you will need to use Recovery or Fastboot mode.
If the file is selected successfully, the device will suggest restarting and starting the installation process. The screen will go out, and automatic flashing will begin. Once completed, the phone will turn on with the version of Android that was in the selected archive.
💡
Use only original firmware files with the.zip extension, as repackaged archives may contain errors and cause installation failure.
It is worth noting that this method is often blocked by developers on newer versions of MIUI for security reasons. If you have managed to pass this stage, consider yourself lucky and avoid more complex technical procedures.
Using Recovery Mode to Reset Version
When the standard method doesn't work, Recovery comes to the rescue, a special diagnostic mode built into every Xiaomi smartphone that allows you to make deep system changes, and you need to turn off your phone and pinch the combination of power buttons and volume up to enter.
In the Recovery menu, the navigation is done with volume buttons, and the choice is confirmed by the power button. You have to select Wipe Data, then Wipe All Data, which will completely clear the device's memory, preparing it for a clean installation of the old system.
After clearing the data, select the Connect with MIAssistant option and connect the phone to your computer via USB-Cable. Run the program on the PC. MIUI Downgrade Tool or use the Downgrade Tool ADB The process can take from 5 to 15 minutes depending on the amount of data.
| Phase | Action. | The result |
|---|---|---|
| 1 | Entrance to Recovery | Launching the diagnostic menu |
| 2 | Wipe Data | Complete deletion of user data |
| 3 | Connect with MIAssistant | Standby mode for connection to the PC |
| 4 | Firmware loading | Install an old version of Android |
It is important not to interrupt the cable connection during the process. If the phone screen is out and the indicator or logo is on, wait for completion. Forced reboot at this point can lead to a cyclic restart (bootloop).
Firmware via Fastboot and computer
The most radical and reliable method is Fastboot, which allows you to completely rewrite the system partition, ignoring the protections that can be at the bootloader level.
If your Redmi Note 8 T bootloader is already unlocked, the process will take a little while. Download the Mi Flash Tool to your computer. Put your phone into Fastboot mode by clamping down and power buttons when the device is off, and plug it into your PC.
In the Mi Flash Tool, specify the path to the folder with the unpacked firmware. In the lower right corner, be sure to select the Clean all option to avoid file conflicts. Press the Flash button and wait for the process to end, which is displayed as a progress bar.
⚠️ Warning: Using the Clean all and lock option will block the bootloader back.Do this only if you are sure that the firmware is completely original and corresponds to the region of the device, otherwise the phone will stop booting.
Once successfully completed, the phone will automatically restart. The first boot can last longer than usual, sometimes up to 10 minutes. Don't panic or touch the device at this time, the system will perform the initial setup.
Solving errors in downgrade
When you go back to an older version of Android, users often encounter errors, and one of the most common is the message "Can't verify update," which occurs when you try to install a version of the system older than the one on the Anti-Rollback.
Anti-rollback is a security mechanism that prevents you from installing outdated versions of the bootloader. If your Redmi Note 8 T has a high level of protection activated, you can only roll back on versions with the same or higher security index.
Another common problem is hanging on the MI logo after you've firmwareed, which can mean a data conflict, and the solution is one: repeat the procedure with full formatting (Wipe All Data), and in rare cases, you need to flash it through EDL Mode, which requires an authorized Mi Account.
What is Anti-Rollback?
If the error is related to drivers on your computer, try replacing them. USB-cable or connect the device to another port using the original cable and ports USB 2.0 often solves problems with unstable connection.
Optimizing the system after rollback
After successful return to the desired version of MIUI, you need to properly configure the system for stable operation. The first hours of the phone may not work stable, as files are indexed and applications are adapted.
Remove unnecessary apps that may have been mothballed after the upgrade, check the battery settings and disable unnecessary background processes, which will help the Redmi Note 8 T run faster and more cost-effectively.
Remember to reconfigure security settings and link accounts. Check the basic functions of calling, internet, cameras, and Bluetooth. If everything works correctly, you can start gradually recovering data from the backup.
💡
After the downgrade, be sure to perform a full reset (Wipe Data), even if the system offers to save data to avoid software conflicts.
Check regularly for updates to Google Play apps, as older versions of programs may not work properly on the new (or returned old) version of the system.
