@Aikuman - Did you try inserting this serial/number, in anyway, before the BIOS bricked? >> 31B31B16K244
If yes, how were you trying to insert that, what tool/method etc? How did the BIOS brick to begin with?

Also, did you downgrade the ME FW yourself, and was laptop functioning properly after that?

Do you know your Ethernet LAN MAC ID, if there is Ethernet port on this model? If yes, send to me

The file above oldbios.bin, is this from the bricked chip, or from some previous BIOS backup you made?
If it's previous BIOS backup, from before it was bricked, how did you make this backup?

No, I did not try to insert the serial number. No, I wasnt downgrade me fw. The bios file comes from a bricked chip

Thanks. That is Wifi, I meant Ethernet, does this system have Ethernet port? If not, then nothing to do here for LAN MAC ID

Do you have ANY previous backup, before it bricked, using ANY method? You didn't answer, how did this BIOS brick to begin with?

I only have what I sent. Generally GPU fans did not work and I decided to program the bios. First I shed old bios and unfortunately I broke leg somehow. Later I upload the new bios from MSI to, new chip but some keys did not always work, only after removing the CMOS battery everything returned to normal.

@Aikuman - So, BIOS (oldBIOS.bin) was not bricked initially, or at all? If this BIOS was working, all you have to do is program this into the new chip.
Then update to latest BIOS normally (using M-Flash), clear CMOS, then boot to BIOS and load optimal default, save and reboot back to BIOS and make all other changes you want.
However, what BIOS chip did you get, if not in list @ post #2 then wait and let me know what new chip ID is, in case we need to edit FD/ME to add BIOS chip compatibility

Only on old bios I have problems, the point is that every 10 min blue screen video scheulder error.
My new bios chip is MXIC 25l6473E

So, do as I mentioned above (see edit), in case you opened this thread while I was editing.
25L6473E is same/equiv to original, so no FD/ME changes needed

What do I have to do now?

Program in oldbios.bin with programmer, be sure to erase/blank check first, then write/verify. Then boot to BIOS, M-Flash latest BIOS from MSI, then shut down.
Clear CMOS, boot to BIOS, load optimal defaults, then save/apply and exit, reboot back to BIOS and then make all changes you want.

Do you mean that I upload old bios to the new chip?

Yes, Program oldbios.bin to chip with flash programmer. Then do as I mentioned above

How to clear CMOS?

Sorry, forgot this was laptop. You may not be able to clear CMOS, but you can try remove main battery, remove power cable, press and hold the power on button for 15-20 seconds, then do rest I mentioned.

I did as you said. I still get blue screen video scheulder error after 10 minutes. The dragon center does not read the temperature and rotation of the fans

Then this could be BIOS bug in that BIOS version, or some driver issue causing that. Program back in oldbios.bin and leave things alone. What do you need updated in oldbios.bin and I can update it for you
