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.
