hmm,
to unlock and backup firmware correctly.
just use no name cheap serial cable from China.
you can find it @ Ebay.
then, use Siemens Service Tool Box or Freia.
I used Siemens Serive Tool Box to unlock it.
and backup for Freia.
Freia is very simple to use; however, Service Tool Box is better...
personally... I think.... but there are more functions with Freia....
I guess nobody uses other than unlocking functions...
and the settings... ex) com port...and stuff...
just go,,,everything default.... do not change any FIFO or whatever... I guess the program is designed work on DEFAULT SETTINGS perfectly. Also, anybody have a problem with making flashes... just format the OS and re-install windows 98 second edition... by this way, I solve the problem, Of course I used different hard drive to it... anyhow,,,, good lucks and happie new year.....................^^^^^^^^^^^^^^^^^^^^^^^^^
