There's no need to take the discussion away from the forum, and I don't use Facebook anyway. The file itself, which you need to rename to just PS3UPDAT.PUP needs to be on a USB drive formatted in FAT32 with MBR in X:\PS3\UPDATE\PS3UPDAT.PUP where X is whatever drive letter the USB drive is on your PC. Verify the MD5 of PS3UPDAT.PUP once it's on the drive and there should be no problem installing it.
If you still have issues, try using a different USB drive because the file
(link here) is not corrupt since countless people have used it successfully without any issues.
