1. Firmware Preparation: What to Do Before Starting

Before you start installing official firmware, there are a number of critical actions that need to be taken, and neglecting them can lead to data loss, locking up the device, or even failure, starting with the obvious: backup.

Backing up data is a must, because the firmware erases all user files. Use built-in tools. MIUI (Settings → The phone. → Backups or third-party solutions like Titanium Backup (requires root:

• 📱 Contact (export to) VCF-Sync the file or sync with your Google Account)
• 📸 Photos and videos (copy to PC or Google Cloud Photos)
• 🔑 App and Wi-Fi passwords (use Mi Cloud or password managers)
• 🎮 Preserve games (if important, manually transfer them)

Then check the battery status. Make sure the battery is at least 60 percent, which will prevent the device from suddenly shutting down during firmware. If the smartphone is dead, plug it into the original charger and wait for it to be fully charged.

⚠️ Warning: If you are flashing a device with a damaged battery (blown or rapidly discharged), connect it to a power source via a power source. USB-A firmware interruption due to a power outage can make the phone unfit for recovery.

Also prepare your Windows computer (Mi Flash Tool requires an OS no lower than Windows 7) and the following tools:

2 Unlock the bootloader: without it anywhere

All modern Xiaomi smartphones (starting with the Redmi Note 3 and Mi 5) come with a locked bootloader, which means that installing any firmware – even the official one – via Fastboot or Recovery is impossible without first unlocking (OTA) Local updates via Recovery without data reset.

The unlocking process includes several key steps:

1. Linking your Mi Account to your device (be sure to use the same account as you do on your smartphone!).
2. Request to unlock via the official Mi Unlock app.
3. The waiting period for approval (usually takes 3 to 10 days, but can take months).
4. Directly unlock through Fastboot.

Important: Xiaomi has tightened the unlock rules, and new devices (released after 2022) require:

• 📱 Tethering SIM-Mi card account (must be active for at least 30 days)

You can download official firmware from two sources:

1. Xiaomi official website (miuidownload.index) – all current versions for all models are available here.
2. Forum 4PDA (partition of your model – often lay out “clean” firmware without unnecessary applications for specific regions.

When choosing a firmware, pay attention to:

• 📌 The device model (e.g. Redmi Note 10 Pro is codenamed sweet, and Poco is codenamed sweet). X3 Pro - vayu. Specify it in settings (Settings) → The phone. → Model).
