I've ghosted my computer lastnight, so don't have flashing log.
about testpoint: I removed battery cable, use the needle to connect all golden point to nearest cage (one by one), after that, I plug usb cable, PC regconised it as SEMC device. so I don't know which one. But I noticed that there is one circle point had 9 small dot inside, I think that it is. I attach picture below.
I cant acces flashmode when use flashtools and PC companion (hold volume down button when connect cable) so cannot flash anything.
No warranty for my phone, it is T-Mobile model, I'm in Vietnam.
