PS3 bricked after firmware update

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.

In case anyone needs help with formatting their drive, or stumble upon similar issues,

1. Remove the HDD from your PS3. (on slim, its on th right hand side at the bottom.

2. Connect it to a Desktop/Laptop. If you have a PC with extra SATA and power cables, connect it directly. Or you can use a SATA-to-USB cable. IF you don't want to buy anything, burn a linux live CD.

3. Assuming you have connected everything perfectly, You should be able to see the hard drive on your PC. ( If you are booting from Live CD, This is your internal storage. )

4. open disk management with Win + X, K(on Windows 8+ devices. Open it from management console on older OS. Right click Computer for the option.) Start gparted (Partitions, gpart, GNU part, or similar.) if on linux or Disk Utility on mac.

5. Navigate to your PS3 drive and format it. Right click for the option. Use FAT32.

6. Reinsert the hard drive into your PS3.

7. Download the latest update package from Sony PlayStation website (This link is for US. Select your appropriate country.

8. Copy it into a USB flash drive (FAT32 formatted). Save in following order: Storage Media ( Flash Drive ) > PS3 > UPDATE > PS3UPDAT.PUP (rename the download file to PS3UPDAT.PUP if the file name is different. This is important!)

9. Boot the PS3, it should start the installation automatically. if not, bot to recovery and select update from storage media.
