WP34s flashing procedure

[Dieter]

Thank you very much to all for your suggestions. After reading your replies it seems that the following procedure should work even if the programming cable's ERASE button does not work:

1. Use a paper clip or something similar to connect the ERASE and VCC contact on the calculator's JTAG pad.
2. Press ON/CE to turn the device on.
3. Remove the paper clip and attach the programming cable.
4. Press the RESET button on the cable. The calculator should turn off.
5. Press ON/CE once again. The calculator should turn on, but the display will stay blank.
6. Transfer the new firmware with MySamba.
7. Press RESET on the cable, then disconnect it.
8. Press ON/CE on the calculator. It should wake up as a WP34s.
   

Do you think this will work?
