Xiaomi’s firmware through Mi Flash: a complete guide from preparation to completion

Introduction: Why you need firmware through Mi Flash and when to use it

Firmware Xiaomi smartphone through the official tool Mi Flash Tool is a radical but effective way to bring the device back to life, update it to the current version. MIUI Or even install custom firmware. OTA-Updating, this method allows you to completely overwrite the system partition, which is useful for critical failures, hanging on the logo or after unsuccessful experiments with modifications.

But firmware via Mi Flash is not a universal solution, requiring bootloader unlocking, which erases all data on the device, and is not suitable for all Xiaomi, Redmi or POCO models. For example, the new flagships of the Xiaomi 14 series may have additional limitations, and budget models like the Redmi Note 12 sometimes need special versions of firmware. In this article, we will discuss the entire process from A to Z, including pitfalls, which are rarely mentioned in standard instructions.

Preparation for firmware: what to do before connecting the phone

The first and most important step is to save data. The firmware through Mi Flash formats the device's internal memory, including photos, contacts and installed applications. Even if you plan to flash the same version of MIUI as before, the data will be lost. Use Mi Cloud for backup or connect your smartphone to your PC and manually copy files from DCIM, Downloads and Miui folders.

Next, check your model’s compatibility with the Mi Flash Tool. Not all Xiaomi devices support this firmware method. For example, Qualcomm Snapdragon smartphones (such as the Xiaomi 13 Pro or POCO F5) are seamlessly stitched, while MediaTek devices (such as the Redmi 10C) may require the use of the SP Flash Tool.

• 📱 Learn the processor model: go to Settings → The phone. → All characteristics → Processor.
• 🔋 Charge the battery to at least 60% – this will prevent a sudden shutdown during firmware.
• 🖥️ Install drivers: download Mi PC Suite or drivers for Qualcomm manually.
• 🔗 Prepare. USB-cable: preferably original, as cheap cables can interrupt the connection.

Pay special attention to unlocking the bootloader. Without this step, the Mi Flash Tool simply won't see your device in Fastboot mode. The unlock procedure takes up to 72 hours (due to Xiaomi's validation) and requires you to link your Mi Account to the device. If you've never unlocked the bootloader before, start with this - otherwise you won't be able to proceed.

💡

If your device is not identified in Mi Flash, try reinstalling drivers manually through Windows Device Manager. To do this, in Fastboot mode, select Update Driver → Search for drivers on this computer → specify the folder with Qualcomm drivers unpacked.

Firmware choice: official vs custom, stable vs developer

The right firmware is responsible for 90% of the success, and Xiaomi offers several types of firmware, each with its own features:

• 📦 Official Stable: Verified version MIUI with minimal bugs, suitable for everyday use.
• 🛠️ Developer: contains new features, but can be unstable.Sometimes requires manual installation via Mi Flash.
• 🌍 Global (Global) vs China: Global firmware supports Google services, Chinese does not. Some models (e.g. Xiaomi) 13T) have separate versions for different regions.
• 🔧 Custom (Custom) ROM): For example, LineageOS or Pixel Experience. requires an unlocked bootloader and may lose warranty.

Where to download the official firmware? Best to use the resources of Xiaomi:

1. MIUI Downloads official website – all versions are available for all models.
2. Xiaomi Firmware Updater is an unofficial but reliable source with a firmware archive.
3. Telegram channels like @MIUIUpdatesTracker are current news and links to fresh builds.

Important: the firmware must match the model code of your device. For example, Redmi Note 11 Pro+ 5G (veux code) will not work with the firmware from Redmi Note 11 Pro 4G (peux code).

Unlock the bootloader: without this, Mi Flash will not work

Unlocking the bootloader is a must before running through Mi Flash. Xiaomi blocks the bootloader by default to protect against unauthorized changes. The unlocking process involves several steps:

1. Mi Account Link: The device must have an authorized Xiaomi account that has not changed in the last 30 days.
2. Request permission: through the official unlock tool (Mi Unlock Tool).
3. Waiting for confirmation: Xiaomi may delay the resolution by 3 to 72 hours (depending on model and region).
4. Connect in Fastboot mode: After approval, connect the phone to your PC and unlock.

Important: once the bootloader is unlocked, all data on the device will be erased, and some features (such as Find Device or Mi Pay) may stop working. On new models (such as Xiaomi 13 Ultra), unlocking may require additional steps, such as confirmation via SMS.

⚠️ Warning: If you bought a smartphone with your hands, make sure the previous owner untie their Mi Account. Otherwise, unlocking will not be possible without their participation.

To check the status of the bootloader, perform in the terminal (with the phone connected to Fastboot):

fastboot oem device-info

If you see Device unlocked: true in the answer, the bootloader is already unlocked. If false, you will have to go through the unlock procedure.
