Hello, have you tried the latest 38,11 version of the Samsung tool?
- The program freezes and "thinks", or freezes and does nothing? Сan you press Cancel?
- See if the card blinks when you press the button, and it would be better to record a video of the blinking.
- And also, what happens if you start the process without a phone?
There is also an assumption that it is the phone itself, as this problem is not common among users.
