After the first fix I came to the possible understanding that I may have not been thorough enough with the repair so I chose to do it again. With more determination and better attention to detail was more thorough but again the repair did not work. At this point what can I do, anything?

@danielames0820 first you will have to remember that there are a few things that can cause the YLOD. A few of them are:
A dead or disconnected HDD
Cold-Joint between the CPU/RSX/EE(If your console has one)
A dead power supply
Overheating
Corrupted NAND Flash
You most likely have issues with your GPU processor. It is a flip chip design and the issue could be the solder bumps between the IC and the substrate. A reflow might fix it for a while but even reflows are very limited. YLOD (as well as RROD on a Xbox) are caused by the design of the processor, not necessarily by bad or cracked solder joints. The only repair that would fix it permanently is a new BGA. Try this repair again and you may have to change the approach a bit by adjusting the heat. It is a hit and miss situation and most first time failure with this is caused by not applying to much heat, whereas to much will totally remove the IC's. Anyhow, the biggest reason for failure to reflow is not enough consistent heat. There is a fine line between reflowing and absolutely melting the solder, so one needs to be aggressive without going over board. If nothing else, get a couple of temperature probes and see what heat you generate. Yes, replace the thermal paste again, do not add to it. The AS5 thermal paste alone will not prevent a YLOD. Apply it according to their specs and it should not give you any issues. You might want to contact the game console guru and see what he thinks.

Sorry for the newb question, but you said "The only repair that would fix it permanently is a new BGA". Would you kindly explain what BGA is and is it possible to acquire it?
Bga means replacing the cpu soldering,
Using a mesh, and bga soldering ball etc.
Sony used cheap soldering wich can met when the console cpus get Hot, this can result in disconnects. Replacing soldering with a higher melting point might fix it.

Are you applying new thermal grease? What's happening when you try to turn it in? Which guide are you following?

Yes I used new thermal paste. I followed multiple videos on YouTube that have used all the same techniques. Reflow the solder correctly, apply new thermal paste, reassemble. Once turned on the fan is low and idle for about 5-10 seconds and then full speed and then proceeds to shut off with the flashing light.
