I'm stuck in a boot loop (HTC One X)

My HTC One X is stuck in a bootloop. The phone is unlocked and I don't know what to do. Every time I reboot the phone it gets stuck in the HTC logo. I was trying to flash a ROM and I think I messed up one of the fastboot commands, something to do with the boot.img file. I don't know what to do. Please help.
