Hi MIUI-ers!

I think that many people have tried to unlock bootloader. Some of them could do it, but someone couldn’t. Therefore, I will give you several solutions, depend on my experience and the Internet sources. I hope that you can give me more ideas after read these solutions to make them perfect.


Before solving the errors, you have to know how to unlock bootloader, click here. These are some information of Bootloader errors and directions to correct.

1. Couldn’t Unlock error

Solution: This is the new policy of Xiaomi when it operates on a new device. You haveto wait 72 hours after login Mi account has been granted Unlock permission and add device to Mi Unlock Status in Settings.

2.
您所在的IP申请次数超标 error

Solution: If you use PC, install Hoxx Proxy and spoof position into Japan. After connecting to VPN of Japan, let your account be signed in again in Unlock login website.


3. 10008:参数错误、 请参考API文档 error

Solution: Some devices are not allowed to unlock bootloader when they are out of China area. You have to spoof IP/VPN into Chinese position. You can use VPN Turbo.
Firstly, you open this app, choose “China” in the list. Then, you activate Fake IP/VPN order and wait for a minute. When you see green symbol, you add your account in Mi Unlock Status.

4. Current account is not bound to this device
error

Solution: Setting -> Additional settings -> Developer option -> Mi unlock states -> add account and device. You add your account, connect your mobile phone to cable, and click Unlock again.

5. Your device isn't supported by Mi Unlock
error

Solution: This error happen because you haven’t had permission to unlock yet. If you have signed up already, click “Go” to access sign up interface. Then, you click “Re-apply” to sign up again. You will be sent permission message. Now, you can make the following steps.

6. Couldn't verify, wait a minute or two and try again
error

Solution: Many people cannot solve this problem, but I can. You should you another account to sign up Mi Account by mobile phone, and use it to unlock.
Note: This new account must have unlock permission already. Although you cannot use account to access Mi Unlock Status, you are able to use it in Mi Flash Unlock.

7. 86006: 参数组合非法 error

I've tried four new accounts for binding accounts but that did not work. Always show Coudln't verify message, wait a minute or two and try again. I never had a successful binding account with my device.

Of course I tried it using plexvpn, turbovpn, monkey fanfan fly vpn. But that did not work. Still stuck with could not verify, wait a minute or two and try again and when going to do ubl stuck with 99% Curent acount not bound.
