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.

Resurrecting Huawei C2830 is simple. Phone is auto powered on with USB Data Cable connected to the PC. Battery presence is not required; connection can be established with detached board. Since the JTAG test points are placed under keyboard sticker we recommend using USB data cable to supply power to the device.
Resurrector re-flashes only firmware zone of the phone (0x000000 to 0x5FFFFF).
Please note: if you do not have JIG (that is you solder wires instead) then black graphite covering has to be carefully scratched off in order to access copper surface of the pads.

To resurrect Huawei C2830:

  • Solder JTAG cable to Huawei C2830 JTAG pads;
  • Insert USB Data cable into board and PC;
  • Make sure Huawei C2830 is selected in the list of models;
  • Click Resurrect button;
  • Wait till software signals a successful operation completion;
  • De-solder JTAG wires;
