The TLDR of an Xbox 360 restoral....

Had the notorious and classical problem that the console turns on and off itself randomly which means that if no deep cleaning and certain settings doesn't avoid that, it means changing the electric flat cable which means uncomfortably opening the console.

Operation went as disastrous as expected as I was not completely "armed" with proper tools and after everything was set and done, in my Second test, apparently the Xbox 360 got the power and eject button not functioning any more.

So I gave in for the night, but woke up motivated on checking again and one last disassembly and finally got the Power functioning (eject function is dead).

ALL THAT...

And at the end... Still turning on and off itself, so it HAS to be particles trapped in unreachable part of the plastic border but don't have time (or brush) now.
