This is a full chain exploit for PS4 firmware 6.72. Basically this is TheFlow's POC together with PS4-specific kROP & kernel patches. Mira is used as a HEN payload.
## READ THIS CAREFULLY BEFORE PROCEEDING
This ONLY works on FW 6.72. If you are on a lower firmware, download a 6.72 retail update file here and update your system. If you are on a higher firmware (e.g. 7.02), your console CAN'T BE HACKED yet.
Click on a link. In about 20 seconds you'll get an alert saying "You're all set!", followed by "There is not enough free system memory". This means that everything has gone well.
If something went wrong during the process, you may get an alert saying "Jailbreak failed! Reboot your PS4 and try again.". In this case you must reboot your PS4.
If the system hangs for more than a minute (may require more time on slow Internet connections), reboot your PS4 and try again.
If the system crashes (looks like instant powerdown), press the power button on the PS4 (NOT on the gamepad) until it turns on again, then retry.
For advanced users: To load your own payloads using NetCat, run Payload Loader and send the payload to TCP port 9020.
Claims that Mira does not have HEN are false, do not believe them!
This exploit does crash and hang. Sometimes you even have to retry 10 times to get the jailbreak.
Note: the speed of the exploit heavily depends on your network speed. If you have a poor network you may have to wait for a few minutes.
