By Jack987 on Jun 25, 2016: #1 Hello, I think I killed my sons PS3. I got a Teensy ++ 2.0 and was following Bailey's guide to get it flashed from 4.8 to 3.55 and was having problems. At first I was able to get the chip to show up correctly in the downgrade tool but after awhile it no longer gave me the right name and code because it went to manufacturer 'unknown'. I was getting reads in the downgrade tool that didn't match many times. I kept checking my wiring and driving myself crazy questioning myself over and over until I knew it was all right. I finally got 3 good reads in a row Wednesday night and patched the file and tried to write it back but the tool stopped several times @ 768k and the downgrade tool froze up in Windows 7. I killed the PS3 and the program. I got frustrated, removed all of the wires from the system, put it together to the point I could connect it to the TV to check and make sure it still worked and it did. I was able to play the pinball game in it. So, I decided to try again next day. At first I was getting 'unknown' in the downgrade tool. Then it saw it fine. Had to go to bed for work next day and since, it doesn't see the damned chip right cause it's 'unknown'. Got annoyed again last night, disconnected all wires and now I'm getting 3 beeps and flashing red light. I have a good soldering station with variable temp heat gun and followed an ifixit article to heat the board and cpu\gpu, I've also grounded PA0 and still get the same thing. Can someone please help!!!!! I feel so bad and guilty because he sunk $80.00 into a new controller and other things and I'm broke. I thought I'd be the 'cool dad' and make things better and usually do with these things but, I may have really screwed things up this time!!! IMPORTANT NOTE: when I had the Teensy connected and before removing it from the system I did have a green light with no beeps.
