I got a Verizon SCH-I545 Galaxy S4 and tried to unlock the bootloader and accidentally hard bricked it. I can't even go in to download mode or recovery mode either. Is there a way I would be able to fix it? I heard that using a USB Jig would fix it. Are there any other way to fix this issue?
I'm not sure if this would help but some additional information:
Baseband Version: I545VRUFNC5
Kernel Version: 3.4.0
Android Version: 4.4.2
I rooted using towelroot. I remember disabling Knox while rooting.
