hi i have a nokia 7250i and i want to flash it because it keeps stalling on certain menus.

i have the following software and a nokia dct4 cable.
WinDCT4
WinDCT4 2.0
DCT4v30
DCT4_125
D4_cool

i was wondering if anybody knows of any guides to flashing nokias or if anybody can tell me how to use this software.

thanks a.eccles
