Re-installing RADIO to device.

[PocketPcUser]

I know Flashing ROM's is not for newbies and that is why I have been doing them without problems many times now. I just ran into a problem with my Radio. Do you know how to re-flash the radio over to the device? I had to disconnect my phone in the middle of the beginning of the FLASH this last time and it removed the radio from my device. The only thing that is on the device now is the actual ROM Mario from Bigj.
Any help at all much appreciated.
I have VZW xv-6700.
Do you know what the deal is with all the problems that people are having with their SD cards?
Thanks,
I look forwards to your reply.
Andrew,
