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

Posted on by

09.09.2011  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.
Please click “Check For Updates” button in order to download and apply new files. Closing all running application before starting update process is recommended.

RIFF JTAG – Samsung I9100 Galaxy S II Unbrick – Boot repair supported, World First ! ! !

29.07.2011     Samsung I9100 Galaxy S II Unbrick – Boot repair supported, World First ! ! !

Samsung I9100 is based on the S5PV310 (Exynos 4210) Processor (Cortex-A9 Dual-Core).

JTAG pads are very small; professional experience in soldering is required to connect wires to the JTAG interface. There is a big variety of versions of Galaxy II devices: GT-I9100, GT-I9100G, GT-I9100L, GT-I9100M, GT-I9100T, GT-I9101, GT-I9103, GT-I9108, GT-I9188, and maybe more. Some of them are based on different hardware platform – the OMAP4430 (Cortex-A9 Dual-Core). Thus make sure first which exact hardware version you have on hands.
Note, one simple way to connect over JTAG – connect USB cable to PC and insert battery. In this case phone is automatically powered on.
Phone has such booting sequence: ROM → FBL → IBL → PBL → SBL. Current resurrector will resurrect Partition Table (PIT) and SBL zones which are located in the iNAND (eMMC) memory. Write access to memory which contains FBL, IBL and PBL loaders is not supported currently, but in case your phone has these loaders damaged, you can choose “Initiate Download Mode” way of resurrection in order to directly put the phone into the Download Mode.

To resurrect Samsung I9100:

  •  Solder JTAG cable to Samsung I9100 JTAG pads;
  •  Connect USB cable to phone and PC;
  •  Insert battery;
  •  Make sure Samsung I9100 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.

To enter download mode:

  •  Disconnect PC cable;
  •  Insert battery;
  •  Hold both ‘Volume Down’ and ‘Home’ keys and press Power-On.
