APM 2.6 and I broke everything

Had issues trying to load new firmware over usb. Kept getting no connection error. Tried to flash using arduino isp. I was having a solid green light, blinking orange, red, and blue at start then blinking red. Now all I have is solid green. Can someone give me a guide to load a new bootloader via ISP, how to do it with arduino uno or I have two serial usb cables for programming my rx/tx and 9xr.
