Hardware E3 flasher to downgrade from 4.75

[devag]

Hi,

I was about to purchase below E3 flasher, but the guy from the store seems to think you cant down grade from 4.75. Is this the case? or are there variations in the type of E3 flasher that you can buy?

any advice appreciated.

The E3 Flasher allows you to downgrade from any OFW, of course if your PS3 is compatible with the flasher (meaning it has a NOR chip in it), and it can also downgrade to at least 3.55 (the firmware required for CFW).

Use this list to figure out if your PS3 is compatible or not.

Here's a guide I used when I flashed my PS3. And here's another guide that I used to unbrick my PS3, when I bricked it by incorrectly flashing it (the clip was not making good contact with the chip).
