Samsung T759 is based on the S5PCxxx Processor (ARM core is Cortex-A8).
Note, one simple way to connect over JTAG – connect USB cable to PC and insert battery. In this case phone is automatically powered on. But note, in some cases it is possible that you will have to hold Power On key during initial connection.
In case after resurrection (after you have tried with both boot versions) the download mode is not initiated (LCD remains blank) do repeat resurrection with ‘Clone Gremlin zone’ option checked.

To resurrect Samsung T759:

  •  Solder JTAG cable to Samsung T759 JTAG pads;
  •  Connect USB cable to phone and PC;
  •  Attach battery connector;
  •  Make sure Samsung T759 is selected in the list of models;
  •  Make sure a fixed TCK frequency is selected;
  •  Click Resurrect button;
  •  Wait till software signals a successful operation completion;
  •  Disconnect USB cable, de-solder JTAG wires;

Now phone is in bootable condition, that is, even if it does not start up normally, you can flash it using original Samsung downloader software to restore it to the working state.

To enter download mode:

  •  Disconnect PC cable;
  •  Insert battery;
  •  Hold ‘Volume Down’ key and press Power-On.
