8.52

[Felix12332]

Can I revert the firmware to 5.05 or can I still install games and homebrew on it? I'd prefer to get it back to 5.05 which I think was the best version for hacking (please correct me if not)

Sorry there is no downgrade.

I ask because in the aio exploit guide it said
FW REVERTING: WORKS
8.XX GAMES: NOT PLAYABLE

 

[Felix12332]

Could I maybe do something like a factory reset and then update to a specific version?

Actually... I answered and then searched. Maybe there is a 8 reversion?

I haven't looked into it yet but you probably need a backup of your nand from before?

Looking into it now... interested.

Hopefully someone can elaborate

reverting is possible, but you must've made preparations on that firmware such as backing up the sflash0. it also requires at least two, possibly three, chips.

 

[Felix12332]

Yeah hopefully

Don't really know what this means

 

[godreborn]

the sflash0 is the main file of the system apparently. it contains the cores, hdd keys, etc.

Like I was saying before, you basically need a "nand" backup from a previous firmware. You would have had to make the backup before upgrade.

Here is a guy doing it

 

[Felix12332]

It'd be my first time doing this kinda thing on a ps4 and the one I'm planning to buy is on 8.52

 

[godreborn]

can't do it then unless you have at least the sflash0 and an hdd backup.

 

[Felix12332]

Oh so I need to make a backup before I can revert it

There isn't 8 exploit yet, but buying a low firmware is good for the future exploits whenever they come.

If you want an exploitable PS4, easiest way is search 6.72 PS4 on ebay

 

[Felix12332]

Damn it's really hard to find one on the right version, wish someone would've figured out a method

 

[Felix12332]

To downgrade I mean

 

[KiiWii]

Downgrade or “revert” isn’t possible without certain files backed up. Sorry.

 

[Felix12332]

Maybe someone could send me a backup but I doubt that would work

 

[Anderxale]

Hopefully some day!

So yeah, maybe ebay for "6.72 PS4"

Or if you are willing to pay for an unopened new PS4, wolo has a list of models to search for on websites or markets. https://wololo.net/2021/02/15/ps4-how-to-get-your-hands-on-a-ps4-with-firmware-7-55-or-lower/

Also I tried looking for one in ebay but I didn't really find much
