I upload some bios files and your upgrade tool. You can find there:
BIOS 18.104.22.168.dfu (beta version)
You have 2 flash tools there: The Pimax version and the "sjefdeklerk" version.
Im trying to find the 22.214.171.124
If somebody can help with more Bios or Piplay files I can Upload all in that Mega folder.
I create a new folder to content some Piplay versions also. You can find there:
Piplay 1.1.92 Beta
Piplay 1.1.92+ PIMAX BE driver (I realy dont know if it is the same like the beta)
Piplay 1.2.63 (It doesn't work to some people, Pimax can not recognize the headset)
Piplay 1.2.74 beta
