Lg g2 mini any method to detect ?

Hi guys I still got hard bricked lg g2 mini d618 ... I was trying to look for solution so I come across many (other) ways to detect but 1 of them was short testpoint or something but I am unable to find it for lg g2 mini and according to reply these tricks are pretty effective ..so I wanna ask and XDA member who is good in hardware things can confirm if these kind of tricks are possible for us (lg g2 mini) users ..Thanks in advance
Note: I got Korean so lg said they don't have it so repair is not an option...
