Problem - Pimax Do not calibrate on steam vr

Already tried to make direct mod work anyway and I could not. Steam vr recognizes in pimax mode but I can not calibrate for it works.When I lift the vr, the device does not appear in the sitting calibration step.
My gforce 1070 is with firmware 368, I did not find compatible old firmware.

Please, what do I do?

Why would you want to use direct mode ? I think it’s become obsolete ?

I don’t understand the question, but is there any problem with steamvr room setup?
If so, see the link

After I saw that they took the direct mode. The problem is that I can not calibrate Pimax on Steam vr
