Recently, we received many requests of Pimax users to downgrade the firmware of their controllers and the headset marker.
As the latest firmware of NOLO CV1 is not compatible with Pimax 4K. If you update the firmware, your controllers will not work normally. (Then you definitely need a downgrade of them.)
Please do not update the firmware until we announce the compatibility of latest firmware with Pimax.
We hope you enjoy your NOLO!
