and i dont have other vr headset now cant afford the new 1
Does the flasher tool when ran manually show the headset?
if so you can likely reflash it. I know there was the vega temp firmware. Have you tried the p4k iirc 299 firmware? Will see if I can find it. @playa 's pimax repo might have it.
Here is a link for the 4k firmware looks like version 999
no after that flasher not show up the headset is not possible to reflash i thing the firmware not succes to write all code for some reason and now the vr is invisible no led nothing is like is not on usb
You may need to do the 3 button sequence to put the hmd into Dfu mode.
Will aee if can find the post. I am sure if needed you can likely file a support ticket.
i try to find way like this but not succes i hold the buttons 2 3 minutes all 3 buttons i dont know if is there any combo but y they not show up now as pimax headset impossible to find the device thanks for reply man i appreciated
Here is @Doman.Chen post on setting dfu mode via 3 buttons.
After setting dfu mode try the manual flasher.
Just heading to bed. Will check tomorrow to see how your made out.
man you are god realy appreciated your help in my old post you are always here for us thanks alot i succes to flash my headset again the only problem now is the black bar on my right eye is stil there this happent when i update on last pitool version i thing is not hardware problem is like the photo but they are there after flash bios after test all piplay and pitool versions the black bar is always there can i add the p4k iirc 299 firmware? on pimax 4k? becase in your other message you say if i test this firmware
Your quite welcome. My apologies I forgot to provide the link for Playa’s repo.

Sorry to hear the black bar is present even in older piplay?
The 999 firmware is said to improve ghosting iirc by making it a bit of motion blur? Haven’t tested it.
You may still want to try a support ticket. With it being 4k you may want to request @Doman.Chen . @PimaxQuorra can likely help with ticket.

Hello,
If you have encounter any other issue after trying this firmware, please kindly file a ticket with our tech team.
thank you to!!! yes all looks fine for now so yes the Heliosurge guy help alot thanks all of you guys. Hereby, wish you happy every day.
My Pimax 4K is not recognized anymore by the PiTools after the flash but the DFU.exe still finds it to flash it back. Returning to the 265 resolves the issue.
Noticed that the 999 firmware removes the HMD name from it, this could be the reason for the PiTools not finding it.

mine work perfect but i do it with the old method ther old piplay not the pitool i dont know if that helps but this version work perfect for me no issues now the 1.0.0.999 is perfect for mine
