Fix Custom Binary block by FRP lock without USB???

[coolguybob]

I recently rooted my phone and soon after (unrelated i believe) i think my phone stopped connecting to a computer with a data cable. It still charged fine. It might be related to when i bought it from a person on craigslist it had dirt stuck in the headphone jack, usb port, and speaker holes. I cleaned it all out with a push pin and maybe I somehow messed up the pins on the usb port? Anyway, I thought maybe a reboot would fix the problem, and when it rebooted i got the "Fix custom binary block by FRP lock" error. (i'm wondering if i accidentally turned off OEM unlocking). I read online how to fix it, however the ways I found all required connecting my phone to my computer with a data cable. I even tried to format/wipe my phone but when it boots i still get the error. Is there anything I can do? I don't KNOW that my usb port is messed up, but that was just a theory, but when I connect it to the computer with ODIN3 or Kies3 it doesnt do anything. Thanks for any help!
