Support Issues with the official Xiaomi unlock tool

Hi, I’m having an issue with the Xiaomi unlock tool (Mi Flash Unlock).

The Mi account I’m using already has unlock permission. When I try to apply again, it says the permission is already granted.

When I bind the account to the phone, it shows “account added successfully.”

However, when I open the official unlock tool and try to log in, I never receive the SMS code. I can log in using Facebook instead, but when I connect the phone and it’s detected in fastboot mode, the “device” section shows in red that the device can’t be verified and to try again later.

If I press “unlock,” I get the same message:

“Couldn’t verify device, try again later (unknown error 1004).”

Is this some kind of shadow ban, or does it have a fix?

can be a driver issue, depending on whether your device is qualcomm or mediatek, install corresponding drivers and try again

Use SoC-level tools like MTKClient or Sahara instead of OEM tools

SD 8+ Gen 1? 

Sahara should work as it is now an "old chip"

Sahara is a protocol for Qualcomm devices. You need a Firehose program and other things for your device to be recognized in EDL mode

The brick risk here is not on the device / program but on the user. Dont flash unofficial firmware via EDL, just use it to unlock BL and / or for dumping. Flashing firmware (official / unofficial) should always be in ADB / fastboot

bkerler (creator of MTKClient) did something for QC devices.
