(adsbygoogle = window.adsbygoogle || []).push({}); Hey guys

I'm downgrading a few PS3's using Progskeet. Just have a question about Factory Service Mode.

Do I need to buy a PS3Key to enter/exit FSM? Or can I use a normal USB dongle, and put the needed files on that? I just bought a 16gb SanDisk off eBay, wondering if I can use that, instead of paying even more money to get PS3Key or similar.

Any answers, advice or links to whatever i need would be appreciated!

Anyone know??
