I have a PS3 Slim 120 GB. I just updated to 4.55, and it got stuck while restarting the system. I force shut it down, and in doing so, I corrupted the hard drive. Now, I do not have any display (I tried HDMI and the AV adapter), and I can't even get into Safe Mode after following the appropriate steps. After removing the hard drive from the PS3, I see the error message that the media storage cannot be found, so I know that my hard drive is corrupted.
But now, I can boot into safe mode by following the steps without the hard drive. I made a USB flash drive with the 4.55 update, so is there a way for me to possibly put the PS3 hard drive in while safe mode is still displayed on the screen, and then restore the update that is on my flash drive to the hard drive? Or can I put the hard drive in while safe mode is running and then restore the file system?
