Hi,
I understood...You phone is started, good.
Give to me more details. Your display is black or blue. If your display is blue, use Joker -> Service mode (your phone is off)->5007 Read->set your display to 126-135)->5007 Write->Phone Off and start your phone without the cable.
If your display is black ....you have the hardware error (possible wrong testpoint cut error).
Br,
