Root Samsung Galaxy S Vibrant SGH-T959 won't turn on at all, HELP!

This is the entire story. My phone used to run with Cyanogenmod 7, but I wasn't able to use One Click Lag Fix app for some reason. So I though I would downgrade my phone to Froyo, and installed the OCLF package. The problem is that I installed Froyo firmware for GT-I9000 model rather than the firmware for SGH-T959 model. My volume buttons were messed up, like other people mention in other forums, but that wasn't the problem. When I turned on my phone it would stay at the recovery screen saying that SD card can't be mounted or something like that. I couldn't access the download mode through the 3 button combo and I know it's different for GT-I9000, however I was able to get my computer to recognize the device. I download the Android SDK tools and I was able to reboot my phone in download mode with adb and got it back to 2.1 firmware with Odin v1.82. I got it fixed, so I went ahead and rooted my phone and I was successful. I was also able to use OCLF app to speed up my vibrant. Then I thought that I would use Samsung Kies to download and install the next firmware available for my phone. While doing this, Samsung Kies said it was successful and to give it a few minutes for the device to reboot. After almost an hour of waiting, the device was completely off. I tried turning it on, and my phone showed no sign of life whatsoever. As of right now, the phone is completely dead, no sign of life, the 3 button combo doesn't work, my computer doesn't recognize the device when it's plugged, and even with the usb plugged to charge, the device won't even show the regular charging battery as it usually does when it's off. I also tried taking out sim card, taking out sd card, and battery and putting the battery back together. Turning it on with a button combo and the usb connection. I think I have pretty much tried everything and I have nothing left. I have browsed through youtube videos and forums, and I find no answer. Every video that they say their phone won't turn on, the phone actually turns on. Mine doesn't even do that. I need help asap! I do not know what to do next. My next guess was JTAG Brick Repair, but I want to know if there is anything else I can do. I ordered a JIG today and I should be getting it tomorrow. That is my last resort, but if that doesn't fix it, or it doesn't get me to download mode, i got nothing left. Please help me I appreciate useful comments.Thanks!
 
You fried your bootloader. Jtag is pretty much your only hope. Hpwever, Jtag will get you back up. On a side note, don't mess with OCLF anymore as it's pretty useless with all the kernels available out there to speed up your phone.
