    i flashed a wrong bios into my RTX 2070.
    I have a RTX 2070 VENTUS GP, and i flashed a VENTUS bios with a little higher power limit, because mine was max 100% power limit.
    Then it flashed, and black screen.

    Only with a paperclip trick i was able to boot with the GPU installed. I can even install Nvidia drivers. But when i try to flash my old bios back into it, it keep saying
    No Nvidia adapters found...

    Is there something i can do?
    Please help i will never flash bios again i promise

    i cannot do anything with NvFlash as it does not detect any Nvidia Display Adapters.

    Got some advice to buy an CH341A flasher, will try this

    @revenge I have an Asus RTX 2070 mini that I successfully cross-flashed with the Asus RTX 2070 EVO OC V2 BIOS to increase to power limit from 175 W up to 222 W.

    Which version(s) of nvflash have you you tried?

    If Nvflash is no longer recognising the card you may need to try different versions.

    I have uploaded some patched versions of nvflash that should work with your RTX 2070. They have all been patched to disable "Override PCI Subsystem ID mismatch".

    Nvflash Patched

    You should use the following command to flash the original BIOS back to the card (assuming you only have one nvidia card in your system and it is index 0) then reboot the system:
    Code:
    nvflash64_5.xxx_patched.exe -i=0 -6 <BIOS.ROM>
    Start with the most recent version of the patched nvflash in the mega link above and work your way back to the older ones if the card is still not being recognised.

    Thank you for your help!
    Tried them all, but it keeps saying "No Nvidia Display Adapters Found"

    @revenge If Device Manager is showing the device as "Nvidia GeForce RTX 2070" with a yellow bang then it looks like Windows has attempted to install drivers and failed.

    Use DDU in safe mode to "clean up and do not restart" and then try Nvflash while still in safe mode.
