A tool that patches Playstation Vita's lv0's secure_kernel's syscall 6 (SELF/RVK checks)

What does that syscall 6 patch do?

  • Removes firmware/sdk version checks from SELFs
    • You can i.e play higher firmware games on lower firmwares, assuming that keys didnt change.
  • Removes RVK-list checks from SELFs
    • You can i.e use the revoked PSM-dev app
  • Some other basic SELFs checks are removed


  1. Put the plugin somewhere, preferably in ur0:tai/
  2. Add a line to the currently active tai/config.txt (ux0 or, preferably, ur0) under "*KERNEL"
    • ur0:tai/0syscall6.skprx
  3. Reboot


  • If the SELF uses new key revisions please use the _renga version with a decrypted kprx_auth_sm (.bin) in ur0:tai/
    • psp2renga framework is required
  • If you are using the psp2renga framework, please use the _renga version to prevent framework overwrite


  • Team Molecule / xyz for the update_sm 0x50002 exploit and help over discord
  • Team Molecule for HenKaku and TaiHen
  • CelesteBlue for StorageMgr (the ssresume hook)
