RIFF JTAG – Samsung SCH-i920 Omnia II 8GB Unbrick – Dead Boot repair supported

Repairing bricked Samsung I920 AP (PDA Part) is easy with RIFF Box. Due to some hardware pecularities, we recommend to use only battery without USB cable connected. Please note, during connection establishment phase you will have to press the Power On key twice.

To resurrect Samsung I920 AP:

  •  Solder JTAG cable to Samsung I920 AP JTAG pads;
  •  Make sure Samsung I920 AP is selected in the list of models;
  •  Insert battery; make sure no USB cable or charger is connected;
  •  Press the Power On key;
  •  Click Resurrect button;
  •  When it stops at “Establish communication with the phone…” press the Power On key again;
  •  Wait till software signals a successful operation completion;
  •  Disconnect USB cable, de-solder JTAG wires;

To resurrect Samsung I920 CP:

  •  Solder JTAG cable to Samsung I920 CP JTAG pads;
  •  Make sure Samsung I920 CP is selected in the list of models;
  •  Insert battery and connect USB cable or charger;
  •  Wait till AP part boots up completely;
  •  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 known flashing methods.
