Problem TP...computer wont recognize it and soft reset button wont work

[dumblondewalkin]

I flashed Mighty Rom 6.5 on my TP a few months ago when I got it. Everything went well but soon after I flashed it, I could no longer connect my computer to my phone. Right now i have it plugged in and all the phone sees is a usb plug to charge it. I want to flash a stock rom on it but I can't flash from the SD card because I can't pull up the bootloader screen...as the soft reset key doesn't work (also worked before mightyrom). I want to fix it but don't really have any ideas
