So I was on my way to work and decided to flash this firmware file JB4_P21_KIA_V22_T4.hex while I was driving. Stupid mistake as I lost all my power and was forced to pull over and figure it out. I tried restarting the car and connecting to the JB4, but when I did it said that I had no firmware and that the car would not work properly (something like that). I was in a hurry so I just ended up taking the JB4 out and run it stock to work. I'm sure this is an easy fix, does anyone have suggestions? It would be much appreciated
