PS4 6.20 Build Strings by Fire30, ETA WEN for Kernel Exploit?

Recently developer Fire30 shared on Twitter some PS4 Firmware 6.20 Build Strings which have been added to the Dev Wiki displaying the current status as 'dumped' leaving many asking the proverbial question of ETA WEN for a public kernel exploit release to complement the PS4 6.XX JSC_ConcatMemcpy WebKit Exploit so PlayStation 4 consoles on recent Firmware can be jailbroken.

Previously Fire30 publicly released a PS4 Webkit Exploit PoC for 2.XX OFW, PS4 HENkaku Exploit for 3.55 Code Execution and FireKaku PS4 3.15 / 3.50 OFW Ports of the exploit... so although he may decide not to do a public 6.20 release at least he has a track record of sharing his findings publicly with the PS4 scene in the past.

To speculate briefly, besides obvious legal hassles a reason he may opt against doing a public 6.20 kxploit release is what developer @Mathieulh (Twitter) mentioned on Discord last month... to quote:

"No one is interested in doing a release for various reasons including how we don't have any other exploit chain after this one XD"

Like it or not, that's a compelling reason to keep things private (for the moment) among PS4 developers since end-users can still obtain jailbreakable consoles if they're willing to pay what those selling them are asking.

I sold my last ps, and for that money i bought ryzen pc, and voila... play everything at same 1080p, only with (in most cases) higher frame rate... Almost everything that interests me is multiplatform, and when tlou2 is out, i will simply borrow ps for few days and play it...

When, if, jailbreak comes out, i will buy used ps... Kinda sad, i prefer ps over pc, but hey... Really dont need 500$ emulator machine

 

[lucasnooker]

I play all multi plats on pc but keep my ps4 for Exclusives. Sony has the best Exclusives for sure and games like Uncharted 4, Bloodborne, God of War, Spider-Man etc are definitely worth keeping a ps4 for. Even if it does collect dust most of the time lol, when a great game comes out I'll be ready for it.

This year we still got days gone which I'm not too convinced about tbh but also the Medievil remake which should be awesome and then Ghost of Tsushima and last of us 2 definitely worth keeping a playstation for...

Death stranding eventually too but honestly don't see that releasing until 2020. The rest of the games don't bother me I'll just get them on pc and play at 4k

 

[Koh23]

Agree...

But in terms of jailbreaking, i played everything i could on 5.05, and played everything up to this date that interests me on 6.20.... then sold it. So, keeping 5.05 or sell it and buy pc, then play metro, re2... Not a brainer for me.

Beside, not sure why, but second hand market in my place is crowded with banned consoles, and they sell it for about 100$, but nobody want to buy it... so, when,lets say 7.0 jailbreak becomes available, for super change i can buy used ps jailbreak it and catch up everything i eventually missed to play....

But, im sad, for sure... miss my ps4

 

[lucasnooker]

Lol I still have 2 ps4s. 1 on 5.05 and 1 up to date but honestly I might sell one too, I don't feel the need for both but it's a difficult decision XD whilst my 5.05 mainly collects dust it's nice to have there because there's still a few games I need to catch up on like horizon zero dawn but most of the other games I already played as they released before the jailbreak.

I keep my new ps4 for when things like red dead 2 and Spider-Man released. I guess I could sell the 5.05 ps4 and just hold out till a new jailbreak comes out but it's also nice to have the collection of the 40 Exclusives I have just in case 1 day I feel like playing the order 1866 or something XD

I avoid it rn because of the terrible reviews and such but 1 day you never know right lol maybe I'll get around to some different games I'd never played eventually so right now I don't sell anything but I should really
