hi i got a few questions, i a new to the world of flashing, so all help would be appreciated.

1. i want to know if it is possible to flash a fone with a datacable.
i heard you have to plug it into the printer port or something, so can't i just get a adapter that converts the 9 pin data cable into the 25 pin connector?

2. how do i convert a 8210 to 8250 & 8850 to 8855?
i looked on the forums, but there was no clear cut explanation. in the 8855 conversion, what chip do you have to replace?, my dad is a technician so he can install. (a tutorial with the list of programs would be nice)

thanks!
