There is no need to disconnect the HMD or uninstall PiTool, just stop all “pi*” processes and tinker with the 3 buttons until you enter DFU mode. Took me a few tries, but hey, this belongs to the experience.
As far as i can see the firmware works great, the increased brightness really makes the image look way more vivid, how it should have been from the start. Tested with some nature videos (REAL nature, lol) and love it !
But it also makes the already horrible mura on my 8KX even more visible …
Quick question B4 I proceed with this, 1 Because I have the optical cable I am assuming I have to use the USB cable 2 copy the 295 DFU file into the Firmware Flasher Tool open CMD and follow the video right?
I’m no expert, but I think you can just use the optical cable. My understanding is that it should act like a USB cable, as far as data transmission is concerned.
Haven’t got any information about release notes for this FW. At least there is nothing new in the version from what I can see.
Optical cable works fine to upgrade firmware, just like the original cable. It still uses the same USB data connection. I use mine every day.
Flasher tool?
Just use the DFU.exe file in PiTool installation directory inside Runtime folder. Browse the firmware file and let it do the job in a few seconds. Just make sure your Pimax is connected and running, and dont unplug or use the headset until it automatically reboots after FW flash.
The 60Hz refreshrate for 8KX is basically done already. Although there is a problem that the team is fighting currently, to make multiple refreshrates in the 8KX firmware to work and switch properly. It introduces some minor issues. Thats mainly the reason why its so delayed. They will solve it for sure.
I have asked Alex earlier this week if we could maybe - meanwhile - just release separate FW for 60Hz refreshrate. Especially since so many flight sim ppl are waiting for it. Let’s hope…
Btw… may I ask why anyone is still using the DFU-mode procedure when upgrading FW, instead of just using DFU.exe? (Unless the HMD FW is bricked).
I did it because I couldn’t get it to work using DFU.exe.
When I tried with DfuSeCommand.exe I found out that it didn’t work either, unless I unplugged the power only (USB 2.0) cable, so it would most likely also work with DFU.exe when doing that…
Good news, backlight adjustment works for me finally with this firmware! (Didn’t work with 294).
Persistance is about the same - noteicable in 114 Hz mode and pretty bad in 75 Hz mode with Eleven table tennis (the probably most demanding game when it comes to smoothness of motion).
I just tried with DFU again this time, also. Like in the attempts before it hung at 98%. Had to resort to DfuSeCommand which worked flawlessly. I had both cables plugged in with DfuSeCommand, still works.
