From everything I've read, that says, "Sorry, you modified the phone, so it's now bricked. Buy another phone."
You should be able to flash the stock ROM ... except for the fact that the PC may not recognize the phone. (JTAGing it might be possible, but buying another phone would be a lot cheaper. (Phones in the V2 class are about USD50. JTAGing a phone runs USD150 and up - if you can find someone who can still JTAG a V2.)
