Also after the job done, I soldered remaining SMC from the 2012 cpu tray to my 2009 cpu tray with no SMC on it. After that it was a perfectly working 2012 cpu tray.

At this point, I don't know why the GPU or PCI SSD would interfere but, all I know is that it only worked when they were out of the equation. I reset the pram and all is great.
