Thank you for your reply...So,I put the phone in bootloader,tried to flash the Cricket Rom in to the phone but it didn't work .....Do you think if I Flash the Sprint Rom it probably works?
[/quote] As I stated in my previous post you will need to flash it to a shipped ROM and as dex says you will need to unlock it also. There is a full tutorial here in the HTC section to help you out.
