While you are adding the Mi account in Mi Unlock status, you may get these type of error messages: “Couldn’t verify, please wait a minute or two”, or ” No network”. These happen, when you use older Mi Devices.
You have to post a thread in the bug sub forum and add the bug report that you will find in Mi Unlock Tool category.
We will recommend you to search if there is the same error thread already posted for your device. If not, then click on the Confirm button for posting the thread to avoid spamming.
