How to update the firmware Xiaomi Redmi Note 8 Pro: the full guide

Xiaomi Redmi Note 8 Pro remains a popular device even a few years after its release, thanks in large part to the regular system updates that the manufacturer brings. Installing a new version of MIUI or switching to a clean Android can significantly improve the performance of the device, increase autonomy and add new security features. However, the process of flashing requires care, as incorrect actions can lead to data loss or software failures.

Before you start manipulating system files, you need to clearly understand what type of update you need: OTA-Update via the settings menu or manually install the firmware archive via Recovery Mode. The first option is suitable for most users who just want to get fresh patches, the second is for those who change the region of the device or restore the system after a failure. In both cases, it is critical to have a stable battery charge and a reliable connection to the internet or computer.

In this article, we will take a look at all the steps of the process, from basic preparation to complex procedures using specialized software. You will learn how to properly download original files, avoid blocking your Mi Account account and what to do if the device has gone into a cyclical reboot. Following the instructions will help you safely update your software.

⚠️ Warning: Before starting any flashing, be sure to back up your important data on an external medium or in the cloud, as the process can result in the complete removal of information from internal memory.

Preparation of the device and choice of firmware method

The initial phase is fundamental to the success of the entire operation.You need to make sure your Redmi Note 8 Pro (codename begonia) is fully ready to interact with the installation files.First, check the current version of the system in the Settings → About Phone section to understand how deep you need to dive into the upgrade process.

There are two main scenarios: an upgrade without unlocking the bootloader and a firmware with unlocked Bootloader. In the first case, you are limited to official global or regional firmware signed with Xiaomi keys. In the second, your capabilities are expanded to install custom recoveries such as TWRP and modified Android builds.

• 🔋 Charge the smartphone battery to at least 60-70%, to avoid sudden power outages at critical time of system sector recording.
• 💾 Free up at least 10 GB of free space on your internal drive for the correct unpacking of archives and temporary files.
• 🔌 Use the original. USB-cable USB 2.0 or 3.0 on the computer motherboard, avoiding front ports of the system unit.

Also, remember to link the device to your Mi Account and enable debugging over USB if you plan to use computer utilities. To activate hidden developer functions, you need to click on the build number several times in the About Phone section, after which the desired switch will appear in the extended menu.

⚠️ Note: If your device has two-factor authentication or anti-theft protection enabled, make sure you remember the password from your Google and Mi Account account, otherwise it will not be possible to activate your smartphone after resetting the data.

Official Update via the Settings Menu (OTA)

The safest and easiest way to update the software is to use the built-in update mechanism, the system itself checks the servers for new versions of MIUI that are suitable for your region and model, and if the update is available, you will receive a notification, or you can manually find it on the menu.

To check, go to Settings → About Phone → MIUI. If the system offers to download a package, agree and wait for the download to end. After that, the smartphone will suggest restarting and starting installation. This method ensures the safety of user data and the integrity of system partitions.

Sometimes the update is on the server, but it doesn't come to the device because of the phased distribution, so you can use the "Select firmware file" feature, available after a few clicks on the MIUI logo, and you need to download the.zip archive from the official website and put it in the root of the internal memory.

💡

If OTA-No updates are coming, try changing the region in the settings (for example, India or Global), check for a new version, and then return the previous region.

It is important to understand that when you switch between regions (e.g. from CN to Global) through the update menu, compatibility errors may occur, in which case the regular bootloader may block the installation, requiring complete data cleaning or using more complex methods through Fastboot mode.

Manual installation of firmware through Recovery Mode

The Recovery installation method is used when automatic updates fail or you need to change the region of the device. The Redmi Note 8 Pro features a stock recovery that can only install signed firmware in.zip format.

Before starting the procedure, download the current firmware archive from a trusted source, such as the official MIUI bootloader portal. The file should have the.zip extension and should not be renamed. Place it in the root directory of the smartphone's internal memory without putting it into folders.

Then you need to enter Recovery mode. To do this, turn off the device and press the combination of the buttons Volume up + Power. Hold them until the Mi logo appears, then release the power button, continuing to hold the volume. In the menu that appears, select the language (if available) and click the button "Install Update" or "Select file".

Once you select the file, the system will request installation confirmation, and you'll agree, and the verification and writing process will begin. If the firmware doesn't work (e.g., trying to roll back to an older version or installing Chinese firmware on a global bootloader), you'll see a message "Can't verify update."

Fastboot and Mi Flash Tool

The most powerful tool for working with Xiaomi devices is the Mi Flash Tool, which works in Fastboot mode. This method allows you to completely reinstall the system, clean all partitions and even restore the device after serious failures. Redmi Note 8 Pro will require a firmware archive in.tgz format, which you need to pre-unpack.

Put your smartphone into Fastboot mode, holding down Volume down + Power when the device is off at the same time. A hare in a hat-outer repairing an android will appear on the screen. Connect the phone to your PC and launch the Mi Flash Tool on behalf of the administrator.

In the program interface, press the Refresh button to let the computer discover the device. Then point the path to the folder with the unpacked firmware. Pay particular attention to the choice of firmware mode at the bottom of the window:

• 🟢 Clean all – complete data cleanup and clean system installation (recommended when changing region).
• 🟡 Save user data – attempts to save user data (may be errors when changing Android versions).
• 🔴 Clean all and lock – complete cleaning and re-locking of the bootloader (use only with the original firmware for the region!).

Critical: Never select the “Lock” option if you are flashing a firmware that does not match the region of the bootloader (e.g. Global firmware on the CN bootloader), otherwise the device will be locked at the motherboard level.

Once you select the mode, press Flash. The process will take 300 to 600 seconds. Don't turn off the cable or interrupt the process, even if it seems like the program is stuck.

Unlocking the loader and custom solutions

For advanced users who want to install custom TWRP recaps or modified firmware, unlocking the bootloader is a mandatory step, without which any attempts to record a non-standard image will be blocked by the security system.

The procedure requires you to submit an application via the Mi Unlock Tool app on your PC and wait for a deadline (usually from 7 to 168 hours). After obtaining permission in the application on your phone, you need to link the account to the device, and then in Fastboot mode, unlock through the utility on your computer.

After successful unlocking, the device’s capabilities expand:

• 🚀 Installation of custom cores to overclock the processor or improve energy saving.
• 🎨 Ability to change system fonts, boot logos and interface.
• 🛡️ Getting root rights through Magisk for full control of the system.

⚠️ Warning: Unlocking the bootloader automatically triggers the full Factory Reset process for security purposes, and it can also lead to loss of warranty and decrease the security of banking applications without additional settings.

Common Errors and How to Resolve Them

When you run the Xiaomi Redmi Note 8 Pro, users often experience a variety of bugs, and one of the most common is “Error 7” or a message that the firmware file signatures don’t match the expected bootloader, which often happens when you try to roll back a version or change region.

Another problem is the Mi logo hanging out (bootloop). If the device reboots cyclically after a failed firmware, try entering Recovery mode and performing a factory reset (Wipe Data). If that doesn't work, you'll need to flash through the Fastboot with a full cleanup.
