Have received Revision 5K+ in early November, SN 20420494223076.
Issue: Firmware 248 turn them into a brick. Older Firmwares than 244 also turn it into a brick. 244 gives a picture, but gives latency and distortion. There have been other users experiencing the same issue who contacted me via PM here and on FB.
65Hz mode is unusable due to this latency, and it is still felt in 90Hz! Some users have reported distortions (Uppi93, me, others).
We cannot rollback to the shipped Firmware, as it is not uploaded.
Please please please provide us the .dfu that are pre-installed on the new Revision 5K+ headsets.
Can we at please get a statement on that? We need that Firmware to rollback, in case we have not declined the automatic function that updates our Firmware to the new incompatible version. Just trying the Beta FW can brick our new 5K+ headsets or create crazy distortions.
At least enable us to do a rollback to the default pre-installed Firmware this way, please.
The only working firmware is 244 from Pitool .197.
If I try to install a Firmware from Pitool .180 or .144 the Headset is not recognized anymore by Pitool and I have to restore it to 244 firmware with DFU Tool.
But with firmware 244 there is crazy distortion and the the 64 and 72 hz modes are missing.
I got my old Pimax 5k+ here so i can compare them next to each other. And the old one has zero distortion and every firmware is working fine.
