Last updated: November 8, 2026. Mi Unlock (miflash_unlock) is Xiaomi’s official Windows tool for unlocking the bootloader of Xiaomi, Redmi and POCO phones. Without an unlocked bootloader you can’t flash a Fastboot ROM with Mi Flash, install TWRP or root your phone.

The latest version is Mi Unlock 7.6.727.43. It is the version most users run on HyperOS phones today. Below you’ll find the official download, a quick-start guide and fixes for the most common errors.

Xiaomi’s own download page (en.miui.com/unlock) still links to the older 6.5.224.28. Both versions talk to the same Xiaomi unlock servers. We recommend 7.6.727.43 because it is the newest build. Use the 2020 and older versions only if a very old phone (MIUI 9–11) refuses to work with the new one.
What You Need Before Using Mi Unlock
- Unlock permission for your Xiaomi account. On HyperOS, you must apply for it in the Xiaomi Community app first. Mi Unlock alone is not enough. Our step-by-step HyperOS unlock guide covers the whole process.
- The phone is bound to your account in Developer options → Mi Unlock status (over mobile data, not Wi-Fi).
- Not a China unit. Xiaomi no longer unlocks phones made for mainland China.
- A Windows PC. Mi Unlock includes its own Fastboot, but installing the Google USB driver avoids “phone not connected” issues.
How to Use Mi Unlock (Quick Guide)
- Extract the ZIP to a short folder, for example
C:\miunlock. - Run
miflash_unlock.exeand accept the disclaimer. - If it asks to install the driver, click Install (it runs
driver_install_64.exe). You can also run that file manually from the folder. - Sign in with the same Xiaomi account that is on the phone and has unlock permission.
- Turn the phone off, hold Power + Volume Down to enter Fastboot and connect it to the PC.
- When Mi Unlock shows Phone connected, click Unlock → Unlock anyway.
- If you get a waiting time (“Please unlock N hours later”), keep the account signed in on the phone and try again after the timer. The phone is wiped and reboots unlocked.
Common Mi Unlock Errors
| Message | What it means |
|---|---|
| Couldn’t unlock. Please unlock N hours later | Normal waiting period (often 72 or 168 hours). Wait and retry. Don’t sign out of your account. |
| Current account is not bound to this device | Bind the account again in Mi Unlock status on mobile data, then retry. |
| Couldn’t verify. Wait a minute or two and try again | Server or connection issue. Check the PC’s internet connection, disable VPN/proxy and retry later. |
| Phone not connected in Fastboot | Driver problem. Run driver_install_64.exe, use a USB 2.0 port and the original cable. |
| Unlock fails at 50% | Usually an account sync issue. On the phone, open Xiaomi Cloud once and make sure Find device is on, then retry. |
| Your account doesn’t have unlock permission / Go to Mi Community to apply | You haven’t been approved yet. Apply in the Xiaomi Community app (HyperOS). |
Mi Unlock Alternatives
For Linux and macOS users, the open-source MiUnlockTool (Python) uses the same official Xiaomi unlock servers. It still requires the same account permission and waiting time. It doesn’t bypass anything, it just runs on other operating systems.
FAQ
Is Mi Unlock safe?
Yes, it is Xiaomi’s official tool. Our 7.6.727.43 download is the original file from Xiaomi’s server, and you can verify it with the SHA-256 checksum above (Get-FileHash in PowerShell).
Can I re-lock the bootloader later?
Yes. Flash the official Fastboot ROM for your phone’s original region with Mi Flash and choose Clean all and lock. Never relock with a modified ROM or a ROM from another region.
Does Mi Unlock work for China phones?
No. Xiaomi has stopped unlocking mainland China devices. Mi Unlock will show an error even if the account was approved.
