What is your phone model?
Try to access download mode and flash stock firmware via Odin.

Sorry mate, that's not possible. You can try a usb jig to force access download mode and flash a firmware, if you are successful once then you can go normally afterwards but it does not always works. Sometimes the damage is too much even for the jig to help.
Then you will have to take it to the service center.

What rom did you flash on the phone?? Post the link where you got it from.
P.S. a 4.0.1 rom is not jellybean, its ice cream sandwich.
