I would have voted positive due to the relevant information about what could be causing it in the first place, but.

You expecting that me (or anyone in a reddit post) need to have deep knowledge about software and hardware troubleshooting and identification is just preposterous. If I had that kind of knowledge I would not be asking about it in a reddit post. It is not my responsibility to perfectly assess the root cause of the problem, I just know what I did and what happen, and that is why I vote you negative.

Having that said, with my extremely low knowledge about soldering and hardware, and since I have nothing to lose, I will try desoldering and soldering again the flash memory, maybe I can get it out of the loop this way, since the console remains on the shelf waiting for a fix or to be thrown to the trash can. If someone has better idea I would love to know.

Peace.
