Hello @jason420 check here = click

Find your model, check the datecode and use minvercheck.

Datecode? I think it's 9C

Use this now. Put the .PUP on a pendrive and then into your PS3 and will say which is the lowest firm you can downgrade = Click

1 - Enter the MinVerChk in the pen, as if it were an upgrade.
2 - Insert the stick into the PS3.
3 - Install the update from XMB (This will fail and display the Firmware Base).

Okay, sorry but I'm new to this lol, I extract the file I just downloaded, copy it over to a USB stick, plug into my PS3 and then install it?

It says Update data version 2.70 or later can be installed on this system. Where I go from here? Do I need to look into getting some sort of flasher? Thanks for the help btw mate

Yeah you need E3 flasher, because your PS3 is NOR. So you are good to go.
Just purchase the flasher and you can perform downgrade.

Needless to say you need to tear open your PS3 in order to this and have basic soldering skills just in case.
