I think I need a jtag topic

I accidentally flashed a rom called Blekota_Note4_Lite_I9300_V3_Aroma for my Galaxy S3 T-Mobile T999L and now it won't boot. Nothing happens. Whatever that rom did it must have written over a lot of files. I made my own jig that doesn't work for my S3 but does work for my S2. So a jig isn't the solution. Tried to make a SD card using this guide but that doesn't work. Though that maybe because I had PacMan rom on it, and before that I had stock 4.1. Also the T999L Sd card debrick did make the phone act different to my computer, as it would usually find QHSUSB_DLOAD but won't with that SD card. I've tried the "SGH-T999 ***NOT FOR 4.3*** Debrick Image" and it would show the QHSUSB_DLOAD on my Windows PC. So that SD card is kinda working but the image isn't for my issue.

Can someone give me a image that will allow me to Odin my phone? If not can someone recommend me a cheap Jtag? :D
