Angry bricked my i747. calling all pros

Hello people, I randomly tried to flash internation model rom on my i747 model s3

it gave wrong model error so i went and modified asserts in the update file and made it pass the check. but phone wont turn on now. i do get red led when charging it. I know it sounds stupid but i just wanted to give a try (was assuming I would unlock the phone )

anyways i do know that 16gb sd un-brick method. but i was wondering if there's a possible different method.

thanks for your time.
