I have the PS3 Slim from 2010 I updated it today to the latest firmware version and after that it is not booting up. I tried entering to recovery but nothing shows up. The light turns on and stays green but nothing happens. After update from storage media, it rebooted but nothing came up for 20 minutes. the i pressed power, nothing happened. I then long pressed it to shut down. I dont think it YSOD but am not sure if the hard disk got corrupted. After that nothing shows up. No recovery options and video reset does nothing.
Edit: So I removed the hard drive and tried going to recovery. Now it shows that there is now hard drive inside. So it is probably is a case of hard disk being corrupted. I will format it by connecting to my laptop and see if something happens.
