RIFF JTAG – Samsung Galaxy S 4G (T959v 1GB) Unbrick – Boot repair supported

22.06.2011  Samsung Galaxy S 4G (T959v 1GB) Unbrick – Boot repair supported

Samsung T959V 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 very rare 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 T959V:

  • Solder JTAG cable to Samsung T959V JTAG pads;
  • Connect microUSB cable to phone and PC;
  • Insert battery;
  • Make sure Samsung T959V 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 both ‘Volume Down’ and ‘Volume Up’ keys and press Power-On.

Please click “Check For Updates” button in order to download and apply new files. Closing all running application before starting update process is recommended.
