anybady know, what if i flash an old modem and the newest PDA, JVT for example.
I flashed JVT.JVT.JVT; CSC was for EU. But i've got a problem with the modem, somtimes nobody couldn't call me and i sometimes couldn't call too.
Now i've flashed back the stock rom wich has CSC = DBT.
Can I only flash JVT in PDA, but modem and CSC leave untouched?
Sorry for my english
