try to connect the testpoints properly and make sure u press the back button before inserting cable

u can do testpoint even with TWIZZER by shorting specific point with any screw or GND -ve

in setool folder you'll find tp pictures.

If you don't find, just google "lt15 tp", in pictures you'll see test point.

If you don't want to solder you can connect it to sim card tray with tweezer, it works like a charm.
