Good morning , should I get a JTAG via gpgjatg of unSamsung gt- i9195 , but not found any detailed explanation , the figure of jat displayed via software do not understand if you have to solder the wires directly on the pins , or if you use a quick plug . The version used is 2.54 RTCK it shows that is not present in the set point of the pin's out . If there is a real guide thank you for your cooperation.
