Installation of stock firmware on Xiaomi: official methods and step-by-step instructions

Why is stock firmware the best choice for Xiaomi?

Xiaomi’s stock firmware is a guarantee of stable smartphone performance, regular security updates and full hardware compatibility. Unlike custom firmware, it is tested by the manufacturer, minimizes the risks of the brick and retains a warranty (if the device is not unlocked). However, even among the official versions of MIUI, there are nuances: global (Global), Chinese (China), European (EEA) and stable/development (Stable/Developer) builds.

Install stock firmware may be necessary in several cases: after a failed experiment with custom software, to fix software failures, before selling a device or when switching from the Chinese version of MIUI to a global one. It is important to understand that the process is different from a conventional update "over the air" - it requires unlocking the bootloader (on most models), using special tools and following instructions accurately. Error at any stage can lead to data loss or device failure.

In this article, we will look at all the current ways to install stock firmware on Xiaomi, Redmi and POCO: through Fastboot, Recovery and Mi Flash Tool, and also analyze the typical errors and their solutions. If you are a beginner, start with the section on preparation, if an experienced user, go straight to the instructions.

Preparation for installation: what to do before the firmware

Before you start installing your firmware, there are a few critical steps to follow: neglecting it can lead to data loss, device lockdown, or even device failure. Start by backing up all your important data: contacts, photos, messages, and apps, and use Mi Cloud, Google Account, or local copying on your PC.

Check the device model and current version of MIUI. You can do this from the Settings → About Phone menu. Write down the exact model name (e.g. Redmi Note 10 Pro or POCO F3) and the firmware version (e.g. MIUI Global 14.0.5 Stable).

• 📱 Create a backup through Settings → Additionally. → Backup and reset or manually copy files to PC.
• 🔋 Charge the battery to at least 60% – this will prevent a sudden shutdown during firmware.
• 🔗 Download drivers for your model from the official Xiaomi website or through the Mi Unlock Tool.
• 🔓 Unlock the bootloader (if it is blocked) – without this installation via Fastboot will not be possible.

Important: On models with a Qualcomm processor (most Xiaomi smartphones), unlocking the bootloader erases all data on the device, including internal memory (photos, videos, apps). On devices with a MediaTek processor (such as some Redmi 9 or POCO M3), unlocking may not be necessary, but this is rare.
