26.10.2011  Samsung Galaxy S Plus (i9001) Unbrick, boot repair supported

Resurrecting Samsung I9001 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.

  •  Insert battery (or connect external power supply to the battery pads);
  •  Make sure Samsung Z500 is selected in the list of models;

RIFF JTAG – HTC Desire Z (HTC Vision) Unbrick, Unlock, IMEI&CID repair supported

12.10.2011    HTC Desire Z (HTC Vision) Unbrick, Unlock, IMEI&CID repair supported

Resurrecting HTC Desire Z 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 Desire Z boards have JTAG interface disabled (that is enable MARM JTAG Fuse is blown in the MSM7230 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 one of selected PDA’s SPL versions (0.76.2000 or 0.85.0005). Additionally to SPL and Radio zones, the zone which contains Model ID is re-flashed too. Thus after resurrection phone will have Model ID = ‘PC1010000’.
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 Desire Z:

  •  Solder JTAG cable to HTC Desire Z JTAG pads;
  •  Insert batter and connect USB Data cable;
  •  Make sure HTC Desire Z 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;
