I'm trying to unlock my MI 8SE bootloader, however I am greeted with the following error upon reaching 50% progress:
Couldn't verify device
After the error, the Mi Unlock Tool just shows "Not connected to the phone" on any subsequent attempts, the connection can only be restored after computer reboot. This is why I am suspecting a driver issue.
Basically I've tried every bit of infomation on the internet, but none of them mention the subsequent inability of detecting phone connection after the first failure. Thus I am posting to seek help.
Here is the application log: https://paste.debian.net/plain/1095622
It can be seen from the log that it tried repeatedly "getvar token" and "getvar product" before bailing out.
