Actually Ylod is pretty easy to repair, I fixed my phat ps3 3 times when it has /btw due to heating it ylod,/ but its been awhile since I have fixed it so I don’t remember the steps.
and to clarify super slim really isn’t hackable its just the ODE so no homebrew, but for that phat ya can use the progskeet seems to be only way to hack the phat consoles so gotta buy that to which is 80ish bucks.
