I have a PS3 ofw 4.88 try to install the latest hfw to be able to then install HEN, when loading the update to 100% it turns off as when it goes into recovery to finish installing, in this case the screen went black for a long time little while. I turned it off and nothing, when I turn it on it stays on but it doesn't give an image and I can't enter recovery mode. Only on, to turn it off I have to keep the button pressed. What is the possible problem? I don't know if it's a brick, because apparently in a brick it always turns off, in this case it doesn't turn off.
