From what I have seen, J-Tag has no issues on a phone that was bricked due to user error. This is a full blown out of the blue EMMC failure. I am about 80% sure that the chip is toast. I have had it happen on a Captivate. Sent it out for J-Tag, came back fixed, 5 minutes later it froze up. Pulled the battery and tried to reboot... Nothing. It was the exact same thing that happened to the guy I bought it from. He was on Facebook and it froze. Same issue.
The J-Tag might bring OPs phone back, but it is unlikely that it will last for even a day.
