Delete the 4.75 spoof and install the 4.76 spoof with the Package Manager if you're on new Rebug firmware. If you are not on new Rebug firmware such as Rebug 4.46.1 REX or below or using someone else's CFW, press Install Package Files in the game section of the XMB and install the 4.76 spoof. Also I don't know what CFW I could recommend but all I can say is I'm happy with 4.70.1 Rebug. Also, NEVER install new updates from Sony as it will remove your jailbreak. For the GTA 5 menu, put that in the dev_hdd0\tmp folder in multiMAN if it is an SPRX menu.
