Follow the instructions "DOWNGRADING AND REVERTING BACK TO ORIGINAL SPL" and "RESTORE THE 1.33.003 PRI"
This will get you back to stock. From here it's up to you if you want to attempt the upgrade again.
I think you might have skipped a step somewhere when dealing with the custom rom. It should have asked you to confirm the flash using power button.
If you didn't get a confirmation then you probably forgot to rename the file.
Try giving Dharvey4651's thread a good reading. He actually wrote a good tutorial on how to recover your device in case something went wrong.
Good luck and please keep us updated.
Oh when he says to use the sprint rom. You want to use your original bell rom ok?
