Have you ever seen the mysterious “Component Update” item in your smartphone, TV or other Xiaomi device and wondered what it meant? This feature is often confusing: some users ignore it, others are afraid to click for fear of “breaking” the device, and still others actively update everything in a row, not realizing the consequences, but in fact it is a critical part of the system that is responsible for the operation of hardware and software at a low level.
In this article, we will take a closer look at what a component upgrade in the Xiaomi ecosystem is, how it differs from regular firmware updates, what types of components exist, and why updating them can both improve device performance and (rarely) lead to problems. You will learn how to properly update components on the brand’s smartphones, TVs and smart devices, and what to do if the process goes wrong.
What are the “components” in Xiaomi devices and why update them
The term “components” in the context of Xiaomi refers to low-level modules that provide interaction between hardware (hardware) and the operating system (MIUI, Android TV, HyperOS, etc.).
- 🔹 Drivers – programs that control the work of the camera, speakers, sensors, communication module (Wi-Fi, Bluetooth, 5G) and other chips.
- 🔹 Corporate software (firmware) - firmware for the processor, graphics accelerator, module NFC or biometric sensors (e.g., fingerprint scanner).
- 🔹 System libraries are instruction sets that use applications to access hardware resources (e.g., libraries for processing graphics or sound).
- 🔹 Security modules – components responsible for data encryption, hack protection and work with Xiaomi servers (for example, for authorization in Mi Account).
Unlike regular firmware updates (which affect the interface, applications and features), component updates work at a deeper level, such as a new version of the camera driver can improve photo processing in low light, and an updated Bluetooth module can eliminate problems with connecting headphones. However, some components are updated automatically with the firmware, and others require manual confirmation – this depends on Xiaomi’s policy for the particular model.
Why does it matter? Imagine your smartphone is warming for no reason, or your camera is turning green in photos, and 30 percent of those cases are due to an outdated driver, not a mechanical breakdown, and updating components can solve the problem without going to the service center.
Component Types in Xiaomi Devices: What You Can Update
Not all components are the same, but can be divided into several categories depending on the purpose and mode of upgrade, and here is a table with the main types found in smartphones, TVs and smart devices of the brand:
| Type of component | Examples | How to update | Frequency of updates |
|---|---|---|---|
| Hardware drivers | Camera, speakers, accelerometer, gyroscope, GPS | Through Settings. → The phone. → Updating components or together with firmware | 1-2 times a year |
| Corporate software (firmware) | Processor (CPU/GPU), modem (4G/5G), NFC, biometrics | Only through official update packages (cannot be downloaded separately) | Rarely (with critical bugs) |
| System libraries | OpenGL, Vulkan, video codec (H.265), encryption | Automatically with firmware or through Google Play Services | Monthly |
| Security modules | Rooting protection, Mi Account authentication | Forced login to your account or through Settings → Passwords and security | As necessary |
| Smart home (IoT) | Communication protocols for Mi Home, Zigbee, Matter | Through the Mi Home app or the Device Control Center | Once a quarter |
Smart devices (lamps, robot vacuum cleaners, cameras) are often featured in a way that is not visible to the user, but can change functionality dramatically, such as a firmware update for Xiaomi Robot Vacuum that may support new maps or improve the cleaning algorithm.
⚠️ Warning: Some components (e.g. modem drivers) are critical to the stable operation of the device, may cause loss of communication or inability to call if the process is interrupted, always monitor battery charge (at least 50%) and the stability of the Internet connection.
How to check and update components on a Xiaomi smartphone
The process of updating components on Xiaomi smartphones (Redmi, POCO, Mi series) depends on the version of MIUI or HyperOS. Below is a step-by-step instruction for most models:
- Open Settings and go to About Phone (or About Device) section.
- Tap on the item Update MIUI (in HyperOS - System Update).
- In the upper right corner, press three dots (⋮) and select Component Update (or Update Packages).
- The system will check for new versions, and if there are, you'll see a selection list.
- Click Download and wait until the process is completed (don’t interrupt!).
- After downloading, tap Install and confirm the reboot.
If the item “Component Update” is missing, this means one of two:
- 🔸 Your model does not support separate updates (components are updated only with firmware).
- 🔸 You have an outdated version. MIUI — Update the firmware to the last stable build.
Battery charge ≥ 50% |Stable Wi-Fi connection |Closed all background applications |Disabled Backup |Device not connected to PC-->
⚠️ Note: On certain devices (e.g, POCO F3 Redmi Note 10 Pro) after updating components may reset the debugging permission USB (ADB). If you use custom firmware or rooted software, you will have to re-enable this option in Settings. → For developers.
Update components on Xiaomi TVs (Mi TV, Redmi TV)
On Xiaomi TVs, the component upgrade process is slightly different from smartphones, where components are most often responsible for:
- 📺 Decoding video (support for new formats, for example, AV1 Or Dolby Vision).
- 🔊 Audio processing (sound correction for different acoustic systems).
- 📶 Modules. Wi-Fi/Bluetooth (Elimination of delays when connecting the remote or headphones).
- 🎮 Game modes (optimization for Google Stadia or Xiaomi Game Turbo).
To update the components on the Mi TV:
- Open the settings (cog on the main screen).
- Go to About TV. → Updating the system.
- Select Component Update (if the item is missing, then updates come with firmware).
- Confirm download and installation, the TV will reboot automatically.
💡 Useful advice: If after updating the components on the TV lost sound through HDMI ARC, Try resetting the sound settings in Settings → Sound. → Factory reset. This is a common problem on Mi models. TV Q2 Redmi Smart TV X.

Risks and Possible Problems in Updating Components
While component upgrades usually go smoothly, there are a number of scenarios where they might fail, and the most common problems and causes are:
- 🔋 Battery discharge during the upgrade → The device shuts down, the components are not installed correctly, and the result is a cyclic reboot or a brick».
- 🌐 The Unstable Internet → Files are downloaded with errors, and the result is that the components are not working correctly (e.g., the camera is giving out artifacts).
- 🔧 Conflict of versions → The new driver is incompatible with the current firmware. NFC).
- 🛠️ Custom firmware → Updating components on unofficial software can lead to blocking the bootloader.
🔹 How to minimize risks:
- 🔸 Use only stable firmware versions (beta versions may contain untested components).
- 🔸 Before updating, check the reviews on the forums (for example, 4PDA or XDA Developers – Are there any complaints about your model.
- 🔸 If the device is rooted, roll back to the stock firmware before upgrading.
💡
Never update components on devices with an unlocked bootloader unless you are sure of compatibility, which could result in IMEI blocking or loss of warranty.
⚠️ Note: Some models (e.g. Xiaomi) 12T or Redmi K50) After updating the components of the communication module, you may need to re-activate VoLTE and VoWiFi manually via ##4636##.
Frequent questions and errors when updating components
Even experienced users face unexpected situations when working with components.
1. "Failure to update the component" error
🔹 Cause: A damaged update file or memory deficit.
🔹 Solution: Clear the cache in Settings → Warehouse → Clear the cache and try again. If it doesn't work, download the full firmware package through the Mi Flash Tool.
2.After the update, the sound is lost or the camera is not working
🔹 Reason: Driver conflict with current firmware.
🔹 Solution: Reverse to the previous version of the component (if available) or reset completely.
3.The device does not see new components
🔹 Reason: Regional restrictions (e.g., firmware for China does not support global components).
🔹 Solution: Re-flash the device to the global or EEA version MIUI.
4.Update got stuck 0% or 100%
🔹 Reason: Section damaged /vendor or lack of space in /system.
🔹 Solution: Perform a reset via Fastboot with the command:
fastboot flash vendor vendor.img(The vendor.img file must be downloaded from the official firmware for your model.)
