Just be careful not to update the firmware on your VR headset. If you update it to a new new version, then it might not be able to connect to 5.05. So I would just leave the headset with v5.05 just in case.
Hi, the PSVR works on 5.05 with all the games. Just make sure to turn off your PS4 and when you turn it on, turn on the VR Headset first before running the exploit and Mira+HEN. Hopefully this helps!!
