Someone asked me how to extract cached files from the PS4 web browser today and so I guess this isn't common knowledge, but you do it like this:
FTP to your PS4 hdd, transfer the file - /user/system/webkit/webbrowser/appcache/ApplicationCache.db...
In case someone is struggling like me with the syscon glitch for days, I would like to inform you that all you have to do is use the right MOSFET, and then it will unlock the system in less than a minute. If you use the wrong one, it will never...
yep, I added support for RL78/G23 protocol, used its new feature "disable debug interface", and wasn't able to enable it back. It's disabled really well.
Though It's not confirmed yet that new Syscon uses RL78/G23 series (in progress)
