I ordered a Bus Pirate and want to try re-flashing it. It's a MacBook Pro 17 inch early 2009 (EMC 2272). It then installed the Firmware, it rebooted and then it did nothing, just a black screen, no startup chime I downloaded and burned the Firmware Recovery DVD and put it in the MacBook Sometimes it would show a gray screen with an X in the middle After reboot it started beeping, 3x short, 3x long, 3x short

I inserted the Recovery DVD hoping it would do something, but now I can't even get it out anymore. In the simplest terms, it's the arms of your drive heads trying to seek across the drive platters, and failing. It powers on, even tries to read the DVD (you can hear it spinning up) but no chime and no screen. it's a very, very high-pitched grinding noise. It showed a gray screen with a progress bar and it completed, it rebooted and then it was completely dead. While shutdown I held the power button until the LED would start blinking rapidly, then it went to what I assume was a firmware upgrade or recovery. So I downloaded the proper recovery CD, burned it to a DVD. Then it started to do funky things, sometimes it would boot to a gray screen with an X in the middle and sometimes it would show a black screen and beep 3x short, 3x long, 3x short. It crashed during the installation so after a few hours of doing nothing I forced a shutdown. So I booted it from a El Capitain USB stick, removed the partitions and created a new one and then installed El Capitain. My wife got the old MacBook Pro of her dad so she can work on it.
