Bios: RomId not compatible / revert back to recovery

[Terminator-X]

Model: MD88157 (P7639), MSN30018556
Real issue: My Geforce 940M does not work. Only intel video. Windows sees a "3d video controller", but cannot install drivers. The Hardware ID of the device confirms it is the Geforce
What happened: My Medion did not start. Was sent to Medion for repair. Worked upon return, but I found out later that Geforce did not work.
What did I do sofar: several versions of the Nvidia drivers from Medion site and Nvidia. Compatible hardware not found. Inserted the Hardware ID, but failed later on. Check this on Win7, Win10 and Linux. All failed.
Medion helpdesk: tried to revert to Medion Recovery from Harddisk. But Power Recover says: Can only be run on a Medion system (????). Helpdesk sent me a new recovery DVD. System tries to run DVD, but starts windows after 20 seconds (same no-Medion error??). Run Power Recover from DVD, same no-Medion error. Helpdesk asks me to press F11 upon boot, nothing happens.
Where am I now: Maybe something wrong with the bios? Maybe due to repair? Downloaded latest Bios for my MSN30018556: WinD17DMD703.exe when extracted. Upon install as administrator under Win10 it quits. Was able to capture the screen just before quit with the burst camera mode from my phone.

Question:
1- How can I get the right BIOS to check if the Geforce still fails?
2- How can I revert to Recovery to check if Geforce fails and make laptop ready for return?

Your given MSN is wrong, it can not be WinD17DMD703. Where do you have your Bios from? May be it is this one

MSN 30018554

@daddlethanks for answering.

the MSN on the sticker on laptop is msn30018556. The helpdesk supplied a DVD with MSN40047549.
I downloaded the bios bioe741x_p763x. When extracted, the file is WinD17DMD703.exe

This one gives the problem of wrong Romid.

@Terminator-X

OK, Bios is for both MSNs the same.

Then, is your Accu charge above 50, better 60 %?

And your computer connected with a wall outlet for charging?

No other program running in the background?

Antiviral software deactivated?

You could try do discharge your laptop from any left over capacity first. 

1. Disconnect charger

2. Disconnect your battery-maybe xou have to open the bottom of the case to do this.

3. Press Powerbutton for 15 to 30 seconds

4. Reconnect battery and charger

5. Restart laptop

6. Try to flash Bios again (deactivate antiviral software first)

@daddle Thanks. Just did all that. Same result. I see a possible solution for a /x method and something about a REV in here:

But I do not have separate files The .exe probably makes the c:/ubios dir and deletes it upon shutdown (see first line in the cdm screenshot).

@Terminator-X

You should be able to decompress the bios.exe with an rar/unrar program.

@daddle
OK, but is this /x method recommended? Anyway to check if the bios is 100% right? So Medion did not mess with repairing my mono?

How should I know? Check your Board-Revision, maybe after repair it's different.

Ask a Medion Mod, or Admin, eg  @Andi or @Luke

Thanks @dadle. I thought you might be from Medion.
