It was no surprise that crypto processes were not handled by the kernel (such was the case for previous Sony consoles). On, Rejuvenate, which was the first public exploit that allowed to run unsigned usermode code, was released. HENkaku only works on firmware 3.60, however the kernel vulnerabilities are present in all firmware versions up to and including 3.60. HENkaku uses two kernel vulnerabilities: Vulnerabilities#Heap_use-after-free_in_sceNetSyscallIoctl and Vulnerabilities#sceIoDevctl_does_not_clear_stack_buffer and a usermode webkit vulnerability. HENkaku enables homebrew by patching out signature checks (works similar to SceKernelModulemgr#Module_decryption_and_signature_checks). The Molecule team was the first to hack the Vita and responsible for the majority of the reversing work done on the Vita. Finally, you need an internet connection to install HENkaku. In order to transfer homebrew to your device, you also need a FTP client for your computer. Internal memory on newer devices is currently not supported.
You also need a memory card (any size) with at least 10MB of free space. Unfortunately, it is not possible to run HENkaku on any device running a higher firmware version and it is also not possible to downgrade your system firmware. You need a PS Vita or PSTV running system firmware 3.60. You must do this every time you reboot the console–that is, every time you turn the console off and on again. Visit from the built-in web browser on your PS Vita and press the “Install” button to install HENkaku. You can find more examples in the showcase.īest of all, HENkaku is 100% free. For example, VitaDoom is a port of the classic game DOOM and mGBA lets you play GameBoy Advanced ROMs. Homebrew are games and other software not officially approved. It is akin to jailbreaking your iPhone or rooting your Android device. HENkaku is the first ever homebrew enabler for PS Vita and PSTV.
