How to Update Xiaomi Phone: 3 Proven Ways + Error Solving

Why it’s important to update your firmware on Xiaomi and what the new MIUI version gives you

Updating software on Xiaomi smartphones is not just adding new features, but a critical procedure for the security, stability and performance of the device. Each new version of MIUI (or HyperOS for modern models) closes vulnerabilities, optimizes iron performance and often improves battery life. For example, in MIUI 14, developers added an adaptive screen refresh rate, which reduced the load on the processor by 15-20% compared to MIUI 12.

But not all updates are equally useful. Sometimes new versions bring not only pros, but also hidden bugs — especially on older models like the Redmi Note 8 Pro or Mi 9T, where fresh firmware can slow down due to a lack of RAM. So before updating it is worth assessing whether you really need it. If your Xiaomi is stable and the new version adds only cosmetic changes (for example, new wallpaper or animations), it may be worth waiting for feedback from other users.

Another key point is regional firmware: Xiaomi smartphones purchased in China often have a China ROM with limited support for Google services, and updating such firmware through standard methods can lead to locking the device, which requires pre-unlocking the bootloader and installing a global version (Global ROM).
