Xiaomi Redmi Component Update: Full Guide 2026

If you’re a Xiaomi Redmi smartphone owner and have noticed “Component Update” in your settings, you’ve probably wondered what it is, why it’s needed, and how to do it correctly. This feature is often confusing, especially for beginners, as it’s different from the standard MIUI firmware update. Unlike the usual system updates that come by air (OTA), component updates affect deeper layers of software — drivers, camera modules, radio frequency protocols, and even hardware settings.

In this article, we’ll go into detail about what’s behind the term “components,” why Xiaomi is separating them into a separate section, and how it affects your Redmi, how to check the relevance of components, how it’s dangerous to ignore updates, and what to do if the process stalls or ends with a mistake, and we’ll also touch on myths — for example, is it true that after an update of components, the smartphone starts to work faster, or is just a marketing ploy.

Now, let me warn you right away, component upgrades are not the same as Fastboot or Recovery, but they're firmware that controls the hardware modules on your device, and if you don't update them, you might run into problems like poor communication, artifacts in the photo, or even overheating of the processor.

What are the components in Xiaomi Redmi smartphones?

“Components” in the context of Xiaomi Redmi are low-level software modules that are responsible for the interaction of the operating system with hardware. MIUI, a separate firmware files that manage:

• 📡 Modem (linkage, 4G/5G, Wi-Fi, Bluetooth)
• 📷 Camera (image processing, autofocus, night mode)
• 🔋 Charging and battery (power controller, fast charging)
• 🎮 Sensors (gyroscope, accelerometer, proximity sensor)
• 🖥️ Display (color calibration, refresh rate)

These components are less frequently updated than MIUI itself, but their relevance is critical to the stable operation of the device. For example, if you do not update the modem, you may encounter problems like “no network” after flashing or resetting, and outdated camera drivers can lead to green artifacts in the photo or HDR that does not work.

It is important to understand that components are tied to a specific model and firmware version. For example, the firmware for the Redmi Note 12 Pro+ will not be suitable for the Redmi 10, even if they run on the same version of MIUI 14.

Why Update Components: The Real Implications

Many users neglect to update components, believing that it is enough to install the latest version of MIUI, but this is a mistake.

• 📶 Communication problems: network disappears, does not catch 5G, Slow internet, even with a good signal.
• 🔥 Overheating and fast discharge: An outdated power controller may misallocate the load, leading to heating and shortening battery life.
• 📸 Artifacts in the photo / video: green or purple spots, dysfunctional stabilization, errors in shooting in the film 4K.
• 🎮 Lags in games: drivers GPU Not optimized for newer versions of apps (e.g. Genshin Impact or Call of Duty Mobile).
• 🔊 Sound problems: distortions in speakers, a broken microphone during calls.

An example of this is that after MIUI 14, many Redmi Note 11 Pro owners complained about the mobile network falling apart, and the solution was found only after updating the modem component through Settings → About the phone → Component Update.

⚠️ Note: If you have custom firmware installed (e.g. Pixel Experience or LineageOS), updating components through a standard menu may result in a device blink.

💡

Before upgrading components, check the battery power – the process can take up to 10 minutes, and interruption due to discharge is fraught with failures.

How to check and update components on Xiaomi Redmi

The process of updating components is easier than it might seem. Here is a step-by-step instruction:

1. Open the Settings. → The phone.
2. Tap on Component Update (on some models, the item may be called firmware Update).
3. The system will automatically check the relevance. If there are updates, the Download button will appear.
4. After download, click Set and wait for the reboot (usually takes 5-15 minutes).

If the Update button is missing, this may mean:

• 📱 You have a global firmware (for example, MIUI Global, where the function is hidden. Try switching to MIUI China or use it ADB.
• 🔧 Your device does not support separate component upgrades (relevant to older models like Redmi). 4X).
• 🛠️ The firmware is modified (castom or with remote system applications).

Battery charge > 50%|Stable Wi-Fi connection|All background applications closed|Backup of important data is made|The device is not unlocked (bootloader locked)-->

For advanced users, if the standard method doesn't work, you can manually update components through Fastboot.

1. Download the current firmware for your model from the Xiaomi Firmware Updater website.
2. Unpack the archive and launch the script flash_all.bat (For Windows, or use the command: fastboot flash modem NON-HLOS.bin fastboot flash fsg fsg.mbn

⚠️ Warning: Incorrect Firmware Components Through Fastboot May Lead to Loss IMEI Use only official firmware files for your model!

Common mistakes and their solutions

Component updates don't always go smoothly. Here are the typical bugs and ways to fix them:

If after updating the components, the smartphone stopped turning on (the so-called "brick"), do not panic. EDL-This will require an authorized Xiaomi account and Mi Flash Pro.

Myths about component upgrades in Redmi

There's a lot of rumors going around this topic, and we're going to look at the most popular ones.

Myth 1: “Renewing components speeds up your smartphone.”

🔹 Reality: Components do not affect performance CPU/GPU. They optimize the performance of specific modules (such as a camera or modem), but do not make the phone “faster” in games or applications.

Myth 2: “If you don’t update the components, the smartphone will break.”

🔹 Reality: The device won't fail, but software bugs can appear, like bad communication or artifacts on the screen.

Myth 3: “Refreshing components resets settings.”

🔹 Reality: Unlike full flashing, component updates do not affect user data, but in rare cases, battery calibration or network settings (e.g., a reset) may reset, APN).

Myth 4: “Components are automatically updated with MIUI.”

🔹 Reality: No! It's a separate process, even if you have the latest version. MIUI 14, components may be obsolete.

💡

Updating components does not replace full firmware, but without it, some features (such as 5G or night shooting) may not work properly.

How to roll back component upgrades if something goes wrong

If you have problems after the update (for example, the camera is not working or the network is lost), you can return the previous version of firmware.

1. Find the archive with the previous version of firmware for your model on Xiaomi Firmware Updater Archive.
2. Unpack the archive and find files with.mbn or.bin extensions (e.g. modem.bin, dsp.so).
3. Fastboot: fastboot flash modem modem.bin fastboot flash dsp.so
4. Reset the device.

If you're not sure what you're doing, you should go to a service center, and if you roll back incorrectly, you can make the problem worse.

⚠️ Note: Some models (e.g. Redmi) K50 or POCO F4) The firmware rollback is blocked by the manufacturer, in such cases only firmware of the full package through the Mi Flash Tool with the unlocked bootloader will help.

Optimization Tips After Component Updates

To maximize the benefits of new firmware, follow a few additional steps:

• 🔄 Reset your network settings (if the modem has been updated): go to Settings → SIM-maps and mobile networks → Resetting network settings.
• 📷 Check the camera calibration: open the Camera app, go to the settings and select Reset to factory.
• 🔋 Recalibrate the battery: discharge the phone to 0%, then charge to 100% without interruptions.
• 🎮 Update the drivers GPU (For gamers: install the latest versions of Game Turbo and GPU Driver from Mi App Store.

If you notice performance improvements after the component update (e.g., more stable FPS in games), it’s not because of overclocking the hardware, but because of optimizing its performance. For example, the new firmware for Snapdragon 8 Gen 1 can better distribute the load between the cores, reducing trottling.

💡

After updating the modem components, check the APN settings – sometimes they are reset and mobile internet stops working.
