Windows may be hiding filename extentions. If you are not sure if the PUP file is named correctly, you can right-click on it and open its properties. The full name will be displayed there. Check that .pup is in the name only once. ps3updat.pup.pup will not work.
Remove any firmware version spoofs before installing a pup! They can cause install to fail.
Do not use USB hubs while installing firmware. Only plug in the USB device with the pup file and your controller.
Thank you for your advice. I checked the file properties and it reads as 'PS3UPDAT.PUP' and says it's a PUP file.
I'm inserting the USB drive directly into the PS3 USB slot closest to the blueray drive.
What do you mean by firmware spoofs? Do I need to downgrade my firmware to 4.88 before installing the HFW 4.89 PUP file? i read it should install over 4.89 via safe mode however I cant seem to get that to work, just tring to work out what it might be. I've tried so many USB drives as well so I'm not sure what the issue is :/
