You'll need JTAG service repair.

He may not if it is a soft brick. As long as when he says softbrick he means that it is not loading past the Samsung log or the ATT logo for example. I was on stock rooted 4.3 as well and tried flashing other roms as well and soft bricked my phone in the process.

I ended up with two choices, load only 4.3 (The STOCK MOD v4 install worked for me just fine - but I was trying to get out of 4.3 tbh) Tried several other roms and all would end in a soft brick.

Finally landed on a stock 4.1.2 UCMG2 rom http://forum.xda-developers.com/show....php?t=2388065

After clearing my internal SD and formatting it I flashed it and it worked (took a long time on the Samsung logo but worked!) the wifi is a little flaky at times but it always was on 4.1.2 for me anyways... the key I believe was that this rom did not have a bootloader and modem updated, which was required to properly downgrade after having had previously installed 4.3.

OP try it out and see how that works? Unfortunately I could not find a TAR of this, but luckily I was able to use a microSD adapter to move the needed files onto the SD card so that I could flash in TWRP.

If he was on stock 4.3 and tried to ODIN to stock 4.1.1, then he's gonna need a JTAG.
If he had tried to flash something via TWRP/CWM then it wouldn't have been an issue.

You do not need a JTAG service. There is a way to unbrick it of you accidentally downgraded your bootloader from 4.3 OTA.
