Default [Q] Hard Bricked SGH-I747 - Need some help

I accidentally formatted my phone's internal storage with a third party app. I intended to format my 16GB micro sd card. A bad oops. It's hardbricked, it won't power on, or get a boot screen. Power + vol down doesn't get it into download mode.

So.....

1. Will a USB jag off ebay work?

2. Would this method work? (dd image to sd card, try to boot off that)

Or any other suggestions?

My last resort is sending it to a repair service that would Jtag my phone.
