Installation of custom and repacked PKG files on a retail PS4 with a kernel's exploit. A totally different and more bullet proof method in comparison with the one from 1.76. A write up on how to achieve this will see the light soon (and again, kernel exploit is needed for that, also porting to other firmwares is possible, and shouldn't be hard).
