Shingen Beta was found to be buggy and it appears the PS4 4.00 OFW is no different, as PlayStation 4 developer @ryan111 discovered a PS4 4.00 WebKit Crash still plagues Sony's latest Firmware update with confirmation from @JNSXModz (YouTube Channel) as well.
Speaking of blogs (we weren't, but are now ) @ryan111's PS4 Dev Blog, which was updated yesterday, now has a few new entries which you can check out here: http://PS4Work.BlogSpot.ca/
Included are kewl things like a PlayStation 4 libSceAvSetting.sprx file dump from PS4 OFW 4.0 and 3.55 / 4.00 store.db files among this core file type (see the Wiki) string discovered: eCoreDumpType: $FDFBD280-90A6-4CFB-ADCC-D0BDBB0A302E
Keep calm and HAX on peoples!!!
