Unlocked BIOS request for MSI GE73 Raider RGB 8RE

[Enigma83]

Hi, I have the laptop listed in the thread title. It is currently running the latest American Megatrends (AMI) BIOS from 2019. My request is simple, i just want all the hidden options unlocked. I would appreciate it if someone could post soon in regards to how to dump a copy of my BIOS so I can upload it. After the mod is done, we can arrange payment.

Thanks!

First, download V12 ME System Tools package from this thread - https://www.win-raid.com/t596f39-Intel-Management-Engine-Drivers-Firmware-amp-System-Tools.html

Once downloaded, inside you will find MEInfo folder, and inside that a Win32 folder. Select that Win32 folder, hold shift and press right click, choose open command window here (Not power shell). Then run this command, and show me the bottom of the report >> MeInfoWin.exe -verbose

If you see Measured Boot or Verified Boot on the left/FPF side, you cannot use mod BIOS on this system (it means Intel BootGuard is enabled and the hash is burned into the FPF fuses on the chipset)

If it's not enabled properly, then you can flash in mod BIOS. Show me image of your Advanced BIOS page, so I can see what all submenus you currently have visible there.

Here is a link to the screenshots, as you've requested. Measured/Verified boot appears to be disabled.

Can you zip all that up for me please and thanks. Good measure/verified boot is disabled!

Before I send you any mod BIOS to test, you need to disable BIOS lock. Here is my guide on that, you can start at step 5-6, I've done 1-5 for you and info is below - https://www.win-raid.com/t3908f16-GUIDE-Grub-Setup-Var-Guide-Fix-Intel-FPT-Error-BIOS-Lock-Bit-Set-HSFS-W-Asus-or-Other-Mod-BIOS.html

Your BIOS Lock variable to change >> 0xA12
Rename your .efi file to >> Shell.efi

So at grub prompt you'll type the following >> setup_var 0xA12 0x0

OK, I zipped it all up for you:

Secure Boot was already disabled, I boot Windows 10 in legacy BIOS mode, but my BIOS is UEFI-capable. BIOS lock now appears to be off as well, the variable stays at 0x0 (I ran the shell a 2nd time to check it). I have also included a pic of the shell's output, because there was an error at the bottom, please check it. The variable you said to change was a success though.

I assume that next you will want me to dump a copy of my BIOS from my PC. Or you cam go to MSI's drivers page and grab a copy of the latest one, which is the one that is installed now:

Once you set that variable to 0x0 it will remain, until you flash in some other stock or BIOS locked BIOS region.

I think MSI can flash in mod BIOS, as long as it's same name as original BIOS, however that may only apply to desktop boards, we'll have to test. If your system wont allow mod BIOS to be flashed in using standard MSI Flash method for this system then we wont be able to use stock BIOS and you'll have to dump BIOS region via FPT. After looking at your BIOS images, I doubt this is possible due to non-standard MSI BIOS, this is just default AMI BIOS not MSI branded, I do see the built in flash option so you may get luck with stock mod BIOS, we'll have to test.

That error can be normal, you can test if successful by flashing back your stock BIOS region using FPT as mentioned below. That should have been 0x1 though by default, are you the original owner of this system? If yes, are you on the 10D BIOS already? Anyway, here's how you check it to confirm it's disabled

In the ME System tools package, Flash Programming Tool folder, and inside that a Windows or Win/Win32 folder. Select that Win folder, hold shift and press right click, choose open command window here (Not power shell).
At the command prompt type the following command and send me the created file to modify >> FPTw.exe -bios -d biosreg.bin

Right after you do that, try to write back the BIOS Region dump and see if you get any error, if you do show me image of the command entered and the error give >> FPTw.exe -bios -f biosreg.bin

If you are stuck on Win10 and cannot easily get command prompt, and method I mentioned above does not work for you, here is some links that should help
Or, copy all contents from the Flash Programming Tool \ DOS folder to the root of a USB Bootable disk and do the dump from DOS (FPT.exe -bios -d biosreg.bin)

Here is simple mod BIOS to test if in BIOS flashing option will allow you to flash mod BIOS or not, this just has BIOS lock disabled by default.
DO NOT use this with FPT, this is only meant as a test with built in BIOS flashing method only.

If you get invalid image or security error, then that means we'll have to edit FPT BIOS Region dump and reflash that way instead.

Yes, I'm the original laptop owner, bought new. As I said, I ran the command in the shell, rebooted back into the shell, then ran it again, the value was 0x0. I just did this to see if it "stuck". Yes, I'm on the 10D BIOS, as stated, I'm running the latest BIOS update for my model which is 10D, also linked to you in my previous post.

I tried the in-BIOS updater method, it says "Failed, wrong image format 11".

I did also back up my BIOS with the command you gave.....writing it back reported no errors, got a green success message.

Thanks for clarifying all that, seems weird since it's 0x1 by default, but this is stored in several locations and not all BIOS use the one we normally change, sounds like yours is one that uses from other location instead, since it's already 0x0 by default.

I assumed you'd get error with stock BIOS method and mod BIOS, so that's expected, sometimes you get lucky and it works. No big deal though, we'll use FPT and I prefer that anyway. Thanks for your dumped region, I will see what I can get unlocked for you tonight

* Edit - here, before I can start modifications I need to know what your default BIOS access level is set to, since Access Level is not shown by default in your BIOS. Please test this BIOS real quick for me, and on the main BIOS page, tell me which one of these new info items you see (Total memory, or Memory Frequency)

Flash via >> FPTw.exe -bios -f MemTFTest.bin

[Enigma83]

Not sure what you mean by access level.....but I see both items you mentioned, and they weren't there before:

Total memory: 16384MB
Memory frequency: 2400MHz

[Lost_N_BIOS]

Access Level is a BIOS thing, tells you what your access level is in the BIOS, like what kind of "user" you are in windows regular or admin etc.

I'll enable for you so you see what I mean, tell me what it says, I suppose if I enable both entries you'll see User and Supervisor just to make this more confusing Since you shouldn't have been able to see both of those I changed previously, I set one to user and the other to Supervisor (admin) so I could have you tell me which showed up, only one should have appeared.

I guess this just means, probably, I can set either one on any missing settings later, that's what this is for mainly (except for chipset tab, we'll probably have to test both ways on it)
