    Hello guys,
    I have a GT72VR 6RE with G-sync MSI Laptop. Sadly the GPU is partially dead (artefacts all over the screen, crashes, windows detecting a damaged hardware etc...).

    So I bought an other GTX1070 MXM on ebay, which was used in a Vorter G65 6RE before.
    Sadly, when I plug the new GPU in the laptop, the laptop screen stays completly off, but i can use the HDMI port. So i though that I would just have to flash the vbios to the one I was using on the GPU that died, but I couldn't because of a mismatch betwen the PCI Device ID.
    The new GPU ID is : 10DE 1BA1 - 1462 11AF and the previous GPU ID was :10DE 1BE1 - 1462 11AF
    Pretty close right? but the A1 and E1 variation are fcking everything up. I've read that 1BA1 is for non G-sync and 1BE1 is for G-sync. I've also read that the G-sync variation is not part of the card but is an external part no on the GPU board.

    So now I'm wondering what can I do : is there a way to force the vbios flash or to change the PCI ID ? I really need some help here. I'm no expert and I've try as much as I could. Maybe I need to do some vbios editing but I don't really know how to do it and what to do exactly to make this work.

    Thank you very much for your help guys

    It's possible. Just try out different 1BE1 Vbios ..

    eventually, one will work.

    Okay so first, I had some evolutions since myf first mesage:
    -I've managed to make the card boot on the laptop screen by flashing a MSI vbios that had the same device PCI ID (1BA1).
    -I tried to install with edited .inf files the nvidia drivers but I still have the error 43 once right after the driver installation
    -When I try to flash my former vbios or any 1BE1 Vbios on the card i got this :
    "
    NVIDIA Firmware Update Utility (Version 5.333.0)
    Simplified Version For OEM Only
    Checking for matches between display adapter(s) and image(s)...

    Adapter: GeForce GTX 1070 (10DE,1BA1,1462,11AF) H:--:NRM S:00,B:01,D:00,F:00

    WARNING: None of the firmware image compatible PCI Device ID's
    match the PCI Device ID of the adapter.
    Adapter PCI Device ID: 1BA1
    Firmware image PCI Device ID: 1BE1
    WARNING: Firmware image PCI Subsystem ID (1462.11FF)
    does not match adapter PCI Subsystem ID (1462.11AF).
    NOTE: Exception caught.
    Nothing changed!

    ERROR: GPU mismatch
    "
    That's why I plan to Hardware flash the vbios of the card in order to change the PCI ID. I will copy the vbios of my old card in the new one with this tool CH341A (I will save both of them first of course, in case something goes wrong I'll reverse the process)

    Do you think this might work ?

    The other option would be to change de firmware on my laptop to make it recognize the 1BA1 PCI ID as a compatible one, but Idk if that is the best option

    Hardware vbios flash is the only option i would reccommend, even though I don't know how to do it myself.

    Could you post your original vbios and the ones you have tried here?

    Following this - I was able to get my 1BA1 card to read a 1BE1 VBIOS but was unable to get past driver errors (error 43.)

    I'll take a look at my gtx 1070 vbios when I get off. If it's a 1BE1 , I'll dump it for you.

    What file size is your VBIOS?
