I solved my own problem.
I downloaded the faster smaller better version of samba from:
http://sourceforge.net/projects/wp34s/files/FlashTool/
Installed that in windows, and picked the com port and the file,
pushed the reset button on the back and the power button on the
front, then sent the file, and it worked! The calculator is
now flashed with the new updated bug-free firmware!
Yea! I am so happy.
The newer 3.1 edition of the manual does refer to the better MySamba flashing program from the sourceforge site, but somehow I was using
an older 2.2 version of the manual that referred me to the atmel
version of the samba program which got me into trouble.
I will delete that older 2.2 manual from my harddrive right now!
