USB method didn't work for me, but i used SD methot with no major issues.
The problem I have is with te windows versions themselves. None that i tried work properly! i tried all the ROM's that you made and 15-20 others and i get the same result : a unusable phone. Then I have to use splexploit most of the times, try another version and so on...
This is the ROM'm I run at the moment: http://forum.xda-developers.com/showthread.php?t=395935
the real ultra light version
...but it's bearly usable: today screen is blank, the dialer is blank, and the TouchDiamond keyboard/kepad/qwerty are a bunch of lines and dots
I guess that what I have to do is modify this ROM in order to get rid of the parts that don't work, but that is a little out of my league, for now
