I've just been digging around and found an old PS3 phat running 3.50 OFW and I was wondering if I can just downloada 3.55 ofw UPDAT.PUP and update the same way you would with 3.55 OFW to 3.55 CFW, or can I just get a rebug firmware and update it?

Download and Install Rebug 3.55.4 then put whatever you want on it.
Set QA flag and your good to install any firmware.

I'm pretty sure you can't update to dex straight away. You have to update to, in your case, 4.75 Rebug CEX and then convert to DEX using rebug toolbox bro.

If you need any help bro just shoot me a PM!

Install Rebug REX 4.78 or higher then convert to DEX in the Toolbox Once you extracted your Eid Key bin again using the toolbox.
Look at the new ish method on how to convert to DEX halfway down on this page.
