04.05.2012 RIFF JTAG – Samsung SGH-T679 Exhibit II 4G (Samsung Ancora) Unbrick – Dead Boot repair supported

Repairing bricked Samsung T679 is easy with the RIFF Box. Phone is auto powered on with USB Data Cable connected to the PC while battery is connected.
Please note, MSM8255T is multi-core chipset – it has ARM11 and Qualcomm Scorpion cores. During power on sequence only ARM11 core is visible on the JTAG chain. If boots are not completely damaged and it comes up to initializing of the Scorpion core then Scorpion core appears on the JTAG chain too. This will shift ARM11 from TAP0 into TAP1 position on the chain, while current resurrector has the ARM11 core hardcoded at TAP0 position. Thus make sure to establish JTAG connection in the time range while Scorpion core is not visible yet.

To resurrect Samsung T679:

  •  Solder JTAG cable to Samsung T679 JTAG pads;
  •  Make sure Samsung T679 is selected in the list of models;
  •  Insert battery and connect USB Data cable;
  •  If you use only battery, press Power On key;
  •  Click Resurrect button;
  •  Wait till software signals a successful operation completion;
  •  Disconnect power supply, 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.

To enter download mode:

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

  • HTC Desire HD (HTC Ace)
  • HTC Desire S (HTC Saga)
  • HTC Desire Z (HTC Vision)
  • HTC Flyer 3G
  • HTC Flyer WiFi
  • HTC Evo View 4G
It is possible to force QHUSB_DLOAD mode by disabling Vdd line on eMMC chip. Check Desire S TP info for example. This means, You can work with any MSM8255/MSM8655 based HTC phone, as long as You force it into QHUSB_DLOAD mode.
Follow this procedure if You want to use these updates:
  • Connect Your phone to USB port and install QHUSB_DLOAD device driver (C:\Program Files (x86)\RIFF Box JTAG Manager\Drivers\32Bit\QDLOADER)
  • Launch JTAG Manager, select appropriate Model DLL and click desired button
  • Install “RIFF Box DCCLoader USB Interface” port driver (C:\Users\Admin\Desktop\Drivers_64Bit_WorkedForMe\Drivers\64Bit\DCCLDR)
  • If required, repeat the procedure (sometimes required if device is connected for first time)

We will release USB support for rest of the models on these CPU-s in following days.

To download and install new updates – simply click “Check for Updates” button on Box Service TAB.
