Developer Options > Mi Unlock Status.🎯 What is Mi Flash Unlock Tool and Why Do You Need It?
Bootloader Authorization UtilityAll modern Xiaomi, Redmi, and POCO devices ship with a locked bootloader by default. This lock serves as a fundamental Android security barrier that prevents unauthorized partition modifications, protects user data against theft, and prevents resellers from injecting counterfeit or modified firmware into genuine hardware.
Xiaomi Mi Flash Unlock Tool is the only official, OEM-authorized software that validates your identity against Xiaomi's servers and instructs the device's bootloader to unlock. Unlocking is required for the following operations:
Essential for unbricking bricked phones, performing clean reinstalls, or downgrading firmware via Xiaomi Mi Flash Tool.
Allows changing your phone's region (e.g. flashing Global or EEA firmware onto China hardware with Google Play services).
Required to flash custom partition recoveries for complete NANDroid backups, ZIP mod flashing, and system tweaks.
Unlocking allows installing Magisk, KernelSU, or flashing AOSP custom ROMs (PixelOS, LineageOS, Evolution X).
🚀 Step-by-Step Guide: How to Use Xiaomi Mi Flash Unlock Tool
Complete WalkthroughUnlocking the bootloader will wipe all internal storage (photos, apps, and files). Connect your device to a PC or use Xiaomi Cloud/Google Drive to save complete backups. Ensure your phone has at least 50% battery.
On your phone, go to Settings > About Phone and tap on OS Version (or MIUI Version) 7 times consecutively until "You are now a developer!" appears.
Then navigate to Settings > Additional Settings > Developer Options and toggle ON both OEM Unlocking and USB Debugging.
Insert a working SIM card with active cellular data into SIM Slot 1. Turn OFF Wi-Fi and enable Mobile Data.
Go to Settings > Additional Settings > Developer Options > Mi Unlock Status. Tap "Add account and device". Wait until you see the confirmation message: "Added successfully. Mi Account is associated with this device now."
Xiaomi enforces a mandatory security wait time—usually 168 hours (7 days). During this countdown, keep your SIM card inside the phone and use it normally. Do NOT log out of your Mi Account, do NOT unbind the account, and do NOT factory reset, as doing so will reset the timer.
Power off your phone completely. Press and hold both Volume Down and Power buttons together until the orange FASTBOOT logo appears on screen.
Connect your phone to your PC using a reliable USB-A to USB-C cable (preferably connected directly to a rear motherboard USB port).
Extract the downloaded ZIP archive on your PC. Right-click miflash_unlock.exe and choose "Run as administrator".
Agree to the disclaimer, sign in with the exact same Mi Account bound to your device, and verify that the tool displays "Phone connected". Click "Unlock", confirm the two data loss warnings, and wait for the progress bar to reach 100% ("Unlocked successfully"). Your phone will reboot automatically with an open padlock icon at boot.
📱 Xiaomi HyperOS Bootloader Unlock Requirements
HyperOS 1.0 & 2.0 PolicyWith the rollout of Xiaomi HyperOS, Xiaomi introduced revised bootloader unlocking policies to heighten ecosystem security. If your phone is running HyperOS:
- Xiaomi Community App Permission: You must request bootloader unlock authorization via the official Xiaomi Community application (Profile > Settings > Unlock bootloader).
- Account Age: Your Mi Account must be at least 30 days old before submitting an unlock application.
- Annual Quota: Each authorized Xiaomi Account can unlock a maximum of 3 devices per calendar year. Authorization remains active for 365 days.
- OTA Updates on Unlocked Devices: Unlocked HyperOS devices will no longer receive automatic over-the-air (OTA) updates; updates must be flashed manually via Fastboot ROMs.
🛠️ Troubleshooting Common Mi Unlock Tool Errors
Quick FixesThis is not an error; it is Xiaomi's mandatory security countdown. You must wait until the timer reaches 0. Keep using your phone normally with your SIM card inserted.
Open the extracted folder, go to the driver folder, right-click driver_install.exe, and run as admin. If on AMD Ryzen PC, use a USB 2.0 port or USB 2.0 hub.
Turn off Wi-Fi, turn on cellular data, and go back to Developer Options > Mi Unlock Status. Tap "Add account and device" again to re-bind properly.
Close the Mi Unlock Tool, re-open it, and sign in again. Alternatively, use the QR-code login option using the Xiaomi Account app on your phone.

❓ Frequently Asked Questions – Mi Flash Unlock Tool
What is Xiaomi Mi Flash Unlock Tool and what is it used for?
The Xiaomi Mi Flash Unlock Tool (miflash_unlock.exe) is the official Windows desktop software developed by Xiaomi Inc. for unlocking the bootloader on Xiaomi, Redmi, and POCO devices. An unlocked bootloader is required to flash Fastboot ROMs with Mi Flash Tool, install custom recoveries like TWRP or OrangeFox, install custom ROMs, or gain root access.
Why does Mi Unlock Tool show 'Couldn't unlock: Please wait 168 hours'?
Xiaomi requires a mandatory security waiting period—typically 168 hours (7 days)—to protect devices against theft and unauthorized third-party vendor ROM installations. During this countdown, keep your SIM card inserted, stay logged into your Mi Account, and use the device normally. There is no legitimate bypass for this countdown; when the timer expires, reconnect in Fastboot mode and unlock.
How do I unlock the bootloader on Xiaomi HyperOS devices?
For Xiaomi HyperOS, bootloader unlocking requires permission through the official Xiaomi Community app. Your Mi Account must be at least 30 days old and have verified Community status. Once permission is approved in the app, you can proceed with the standard Mi Flash Unlock Tool on your PC.
Why is Mi Unlock Tool not detecting my phone ('Not connected to phone')?
If the tool shows 'Not connected to phone':
- Ensure your phone is booted into Fastboot mode (hold Power + Volume Down).
- Inside the extracted Mi Unlock Tool folder, open the
driversubfolder, right-clickdriver_install.exe, and run as Administrator. - If using an AMD Ryzen PC, connect your USB cable to a USB 2.0 port or use a USB 2.0 hub, as AMD USB 3.0/3.1 controllers often drop Fastboot handshakes.
Does unlocking the bootloader wipe personal data?
Yes. Unlocking the bootloader automatically triggers a complete factory reset and erases all internal storage, downloaded apps, photos, and personal data to protect privacy. Always back up important files before proceeding.
Can I re-lock the bootloader after unlocking?
Yes. You can re-lock the bootloader by flashing an official stock Fastboot ROM (.tgz) using Xiaomi Mi Flash Tool and selecting the 'clean all and lock' option (flash_all_lock.bat). Caution: Never attempt to lock the bootloader if your device is running a custom ROM or modified partition, as this will hard brick the device.
Which versions of Windows are supported by Mi Flash Unlock Tool?
Xiaomi Mi Flash Unlock Tool supports Windows 11, Windows 10, Windows 8.1, Windows 8, and Windows 7 on both 64-bit (x64) and 32-bit (x86) architectures.
