I need serious HELP!

[twisterxb]

I have a sprint 6900 that was flashed to metro pcs.

Last night i tried to flash the 6.5wm 21501 rom. It seemed like it was working fine but when the phone restarted it didnt load up. It froze at the PPCGEEKs screen.

I put the phone in boot loader mode. I have the .41 coke

I tried relfashing the stock rom from spring but i get error 262. I think its because my phone isnt connecting to WMDC. I'm running windows vista on my PC.

Is there anything im missing? do i need to unlock my phone? if so how? because i already tried but it seems like when i try to unlock it the program cant find my phone.

HELP!! lol
