Hello,
I am new here.
I have the same NB ASUS STRIX GL753VE , BIOS 308

Can I use the modded BIOS from here? Or I have to dump my BIOS because of region ? And then send it in here?

Thank You

This is all I know about the possible settings - https://leshcatlabs.net/forums/printthread.php?tid=55

@Vesly - Sorry for major delay, I just now came across your post! No, you cannot use BIOS here, all BIOS are user specific and we have to edit your own BIOS

You need to follow this guide first to disable BIOS Lock, start at step #6 because I will give you info from 1-5 below.
[GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash

Rename .efi file to >> Shell.efi

BIOS Lock variable to disable >> 0x8AA

So at grub prompt you will type the following, and then hit enter then reboot once done and do below FPT stuff again (Toss previous FPT file out)
This is case sensitive!

setup_var 0x8AA 0x00

Then once you do this, follow steps #1 and #2 in the spoiler below, and once you pass step #2 successfully you have unlocked your BIOS, send me that new FPTw BIOS region dump and I will unlock it for you.

Hello, I shed a bios on my BIOS Version: GL753VE.308. Is there a chance to unlock the hidden menu?

@krzychunh - did you already disable BIOS Lock, and can pass step #2 in above FPT spoiler? If not, do as mentioned above for Vesly, that is correct variable for your BIOS too
Once done, make new BIOS region dump with new name and confirm you can flash it back (step #2 in FPT Spoiler above)

I unlocked from the Bios level, turned off security and dumped. FTP allowed me to dump. Do you additionally need to unlock anything additionally? Does this copy have all MAC SN card data etc.? I don't want to lose it.

@krzychunh - You need to disable BIOS Lock, as I explained in post #18. You cannot do that from BIOS, and you can always dump BIOS region with FPT, this is not an issue.
After you disable BIOS Lock in Grub w/ setup_var, then make NEW dump with FPT using new bane, and try to write it back, once you can write it back, then send me the new dump.
Basically, see post #18, first part, do that. Then boot back to windows and do FPT spoiler step #1 with new biosregnew.bin name, then test step #2, if success then upload biosregnew.bin for me to unlock.
Yes, your BIOS region dump has all your system specific info it it, and that will remain in place

I already have the option to unlock the bios, do I still need to follow these steps? =)

Please clarify what you mean you "already have option to unlock the bios" This is not an option in the BIOS, and you are asking for unlocked BIOS here, so you need to tell me exactly what you mean?
But to answer you anyway, yes, you need to do what I said, otherwise you can't flash back in mod BIOS

I have Bios security options in Bios, if it was active I couldn't rip FPT because it thrown an error 368, turning off bios protection, there was no error anymore dumped the bios to the bin file

@krzychunh - You can always dump BIOS with FPT, writing back (Step #2) is the issue where you see error 368
Test, can you write back your dumped BIOS region now >> FPTw.exe -bios -f biosreg.bin

If yes, then OK, I will mod for you and you flash back, if you can't do FPT command above and get error 368, then you have to do what I mentioned.

@krzychunh - Sorry, maybe some translation issues? Yes, I know it's dumped BIOS, can you write it back or not, this is the issue right now until you confirm OK >> FPTw.exe -bios -F biosreg.bin << Can you do that, and not get error 368, YES or NO??
If you cannot write it back, then you need to do as I mentioned at first part of post #18, if you CAN write it back, let me know

I did your steps but I have a 370 error





I dumped the bios again to see if something changed from 0x1 to 0x0

@krzychunh - You cannot check changes made in grub/setup_var by extracting setup module, changes are not made there but are set in NVRAM instead.

Looks like you messed something up, or you need to reboot and try again (about error 370)

Thanks for your grub image, there you can see it was already 0x00, and then set again to 0x00, so all unlocked now.
You just need to reboot, dump BIOS region again with new name, and send me that file, then confirm you can write it back >> FPTw.exe -bios -f biosregnew.bin

* Edit - Hmm, not sure, looks like offset out of range, so could not be changed by grub/setup_var, but if that is correct readout initially, then it's unlocked anyway.
If it is, then you can write back BIOS region without error 368, if you still get error 368 now, then I will have to show you how to check and change this from 01 if needed to 00 using DOS and RU program.
