Bebop 1 just blinks

I have a Parrot Bebop 1 that just blinks green no matter how many times I try to reset it or upload the firmware with a usb directly to drone. My only option is to go through the UART on the side and try to reflash it with firmware, so I can bring it back to life. I have no picture of the cable I am suppose to use, I have a USB cable on hand with with TX,RX and ground pins (FTDI). Would this work? If not any pictures of how the cable is suppose to look, Or If I can buy one already made?

Next is the procedure and steps of actually re-flashing the firmware. I have looked all over the net with broken results. If someone can provide that with any downloads or pictures I would greatly appreciate it.

Surely someone must know how to reflash
