Resurrecting Samsung S8600 is easy. Phone is auto powered on with USB Data Cable connected to the PC while battery is connected.
Please note, MSM8255T is dual 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 S8600:

  •  Solder JTAG cable to Samsung S8600 JTAG pads;
  •  Make sure Samsung S8600 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;

RIFF JTAG – HTC Droid Incredible 2 ADR6350 Boot repair, Unlock, CID, ModelID, IMEI Update

HTC Droid Incredible 2 ADR6350 Boot repair, Unlock, CID, ModelID, IMEI Update

Resurrecting HTC Incredible 2 (Droid Incredible 2 ADR6350VW) is easy. Phone is auto powered on with USB Data Cable connected to the PC while battery is connected.
Some (or all) revisions of HTC Incredible 2 boards have JTAG interface disabled (that is enable MARM JTAG Fuse is blown in the MSM8655 chip). In this case the JTAG may be enabled only by firmware itself. This is done by the FSBL loader, so writing to FSBL area is artificially disabled in the DCC Loader code. DCC Loader will discard all flashing attempts into FSBL zone and will respond with success code as if flashing succeeded. In this way FSBL zone is protected while user still can flash full image files seamlessly.
Resurrector will reflash radio’s boot zone (except FSBL area) and will re-write PDA’s SPL version 6.13.1002. Additionally to SPL and Radio zones, the zone which contains Model ID is re-flashed too. Thus after resurrection phone will have Model ID = ‘PG3210***’.
There is option to reflash BOOT and RECOVERY zones.
Please note, if your phone has the FSBL loader damaged and MCU has JTAG FUSE blown then there is no way to resurrect your phone via JTAG interface.
To resurrect HTC Incredible 2:

  •  Solder JTAG cable to HTC Incredible 2 JTAG pads;
  •  Insert batter and connect USB Data cable;
  •  Make sure HTC Incredible 2 is selected in the list of models;
  •  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;
