Flashed the wrong VBIOS I guess

I'm on a Razer Blade 15 with 1070 Max Q inside - what baffles me more is that an unmodded version of Nvflash allowed this to happen.

 

Now when I try to flash to my backups it's telling me "GPU mismatch" cause the PCIE ID (?) is off by 1 letter - 1BE1 vs 1BA1 - there must be a way to ignore this and force it? I've Googled around and none of the supplied commands are working. I can't get my head round not being able to force flash my own backup back on?

  1. Find the backup
  2. Open it in a hex editor (e.g. HxD)
  3. Find the string containing the PCIE ID
  4. Change it to the appropriate value
  5. Flash

Looks like we're getting somewhere here but in HxD there are no search results for "PCIE ID" ...

More than likely there won't be "PCIE ID" as it's a hex file and has no reason for such labels. Just search for the ID itself E.g.  "1BE1" or "1BA1"

Here's the search result for "1BA1" ... all of this looks encrypted to me bud, are we going to be able to fix it this way?

Can you attach a copy of the backup and let me know the full PCIE ID. I'll take a look

Thanks man!

 

It should be: 10DE 1BA1 1A58 2000, we're off by 1 letter: 1BE1

backup.rom 232.5 kB · 1 download

https://www.techpowerup.com/vgabios/186329/asus-gtx1070mobile-8192-160701

Is this the BIOS you flashed?

Also, Still working on the file. It identifies as 1BE1 now and should allow you to flash, but I don't want to add any extra data so I'm trimming down the modifications right now so nothing should brick

EDIT: My bad, was this one https://www.techpowerup.com/vgabios/186340/asus-gtx1070mobile-8192-160713. :/

 

Maybe this will help for modding the file? Original BIOS backup I uploaded before all this: https://www.techpowerup.com/vgabios/213833/213833

 

EDIT: I think we're going to have to make the computer recognise it as 1BA1 to get the NVIDIA drivers working again tho ...

Possibly. Here's the modified backup file and the change made, thankfully it ended up just being four bytes

 

Here's what I'd like you to do:

  1. Attempt to flash the backup using this version of Nvflash: https://www.techpowerup.com/download/nvidia-nvflash-with-board-id-mismatch-disabled/
  2. If Step 1 fails, try to flash the backup_updatedheader2.rom using either your current nvflash or the nvflash from step 1

Already been thru step 1 a few times, no dice. :/

 

Any special commands for step 2?

It shouldn't need anything extra. It's been modified to match the board id and nothing else. If you're getting error messages then please attach them.

OML. Probably some checksum bits. Try this one, This one included some extra bytes I removed to be safe that may have been checksums. If it doesn't accept this one then I wouldn't know how to proceed. I'll be back in a couple hours after my dentist appointment

Same error about BIOS Cert 2.0 ... and the certificates bypassed version of NvFlash doesn't work with Pascal cards as far as I can see? Is there another way to bypass this cert thing?

 

Thanks for all the help so far man!

 

EDIT: Local guy seems like he understands how to write the BIOS with a programmer chip - is this the way forward?

UPDATE: I flashed an Alienware VBIOS on the offchance it would do something and suddently my card appeared in Device Manager as a 1070 Max Q and not "Microsoft Basic Display Adapter" - I also noticed it's now showing as 1BA1!? Long story short, reflash my 1BA1 original backup and we're back to stock. :)
