30.09.2011  Samsung Wave II S8530 Unbrick, Boot repair supported

Samsung S8530 PDA is based on the S5PCxxx Processor (ARM core is Cortex-A8).
You will have to carefully scratch off the mask covering in order to access copper surface of the JTAG pads.
Note, one simple way to connect over JTAG – connect USB cable to PC and insert battery. In this case phone is automatically powered on, so no need to press any power-on buttons on the phone keypad.

To resurrect Samsung S8530:

  •  Solder JTAG cable to Samsung S8530 JTAG pads;
  •  Connect USB cable to phone and PC;
  •  Insert battery;
  •  Make sure Samsung S8530 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. We used MultiLoader 5.64 version.

To enter download mode:

  •  Disconnect PC cable;
  •  Insert battery;
  •  Hold both ‘Volume Down’ (from the left side of phone) and ‘Hold’ (right side at top) keys and press Power-On.

RIFF JTAG – HTC Desire S S510E (HTC Saga) – Unbrick, Unlock, CID, IMEI Update supported

Resurrecting HTC Desire S 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 S boards have JTAG interface disabled (that is enable MARM JTAG Fuse is blown in the MSM8255 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 to 0.98.0000 version. Additionally to SPL and Radio zones, the zone which contains Model ID is re-flashed too. Thus after resurrection phone will have Model ID = ‘PG8810000’.
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 S:

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

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.

25.08.2011  HTC Wizard 200 Unbrick – Boot repair supported

Resurrection of HTC Wizard 200 is simple. Battery must be connected in order to establish JTAG connection.
Current resurrector works with devices based on G4 MDOC chip.
Resurrector can repair IPL and SPL areas (which areas to repair you can select in popup window).
Please note: DiskOnChip G4 memory has security features, due to which there is a risk of permanently blocking the access to the flash memory while re-flashing the IPL area. Thus be very carefull not to interrupt IPL repair process (in case you have selected IPL area to be repaired).
In case your device has permanently blocked MDOC memory you will see this error:

****************************************************************
Detected a Not Initialized FLASH1 Chip ID: 0x0400/0xFBFF
ERROR: Selected FLASH Chip was not initialized by the DCC Loader
****************************************************************
This can happen due to unknown protection keys used or due to permanently blocked MDOC chip. If latter is true we advise you to solder a new flash memory chip or throw this phone away to the trash bin.
