As far as know, when flashing a kitchen using Olipro 2.40, active sync appears to be dicsonnected when in actuality the connection is still there. I had a similar experience and got tremendously worried. Even if it does not work the first time, just remember to go back to booting into Olipro, and starting with the sprint ROM flash (as per link below).
I have been recommending this set of instructions for newbs because I myself am one. Its pretty straightforward, just follow the instructions. I just hope XDA gets back online soon.
