I900 crash after update

[Guest GTKiller]

Hello, I am new to the board, and i just recieved my i900 this week and i tried to flash to dzhj1 rom. I downloaded the modem drivers and the update from the samsung update site. I am running xp on my laptop. I started the process the phone turned off afetr the first file was downloaded. The updater asked me to manually turn the phone on, but the phone doesnt turn back on. Im afraid i just wasted 600+ US dollars. what can i do
