Gigabyte Aero 15 v8 (FB0A BIOS Unlocked)
#1
Disclaimer: Do this at your OWN RISK! I will not be held responsible for anyone bricking their machine!

I made the mods based on @Lost_N_BIOS's post here and by following the How-2-Rip-It-Open-Yourself guide here.

This patch has been confirmed to work with both 15X v8 and 15W v8 models. Make sure you have your Aero's BIOS flashed to version FB0A using the official release on the Gigabyte website here before attempting the following.

First you must run command prompt (as Administrator) and run "FPTw.exe -bios -d biosreg.bin". You can get FPTw.exe from Intel CSME System Tools v12 r18 (located in the "Flash Programming Tool" folder).

Next you will need to run UEFITool 0.26.0 and open biosreg.bin. Select File->Search... Text tab and enter AMITSE. A list of search results will show at the bottom. Double click on "Unicode text "AMITSE" found in User interface section at offset 0h". Right click on the "PE32 image section" and select "Replace as is...". Browse to the (unzipped) file attached (Section_PE32_image_AMITSE_AMITSE.zip). File->Save image file... and call it biosmod.bin.

Then you need to run AMIBCP 5.02.0031 and open biosmod.bin to set the menu access to USER like so:

Once you File->Save run "FPTw.exe -bios -f biosmod.bin".

If you get the following error:
Quote:Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.

This is caused by the BIOS Lock variable set to 0x01 (Enabled):
Code:
BIOS Lock, VarStoreInfo (VarOffset/VarName): 0xA12

How to set the BIOS Lock variable to 0x00 (Disabled):
1. Make sure you have following values set in BIOS:
  - Legacy Support: Disable
  - Secure Boot: Disable
2. Take USB stick and format to FAT32
3. Create directory structure EFI\Boot
4. Download and unzip bootx64.7z
5. Put BOOTX64.EFI into Boot directory
6. Boot from this USB stick
7. Run command: setup_var 0xA12 0x00
8. Run command: reboot

Attempt to write the modified BIOS again using FPTw.exe.

If successful this time run "FPTw.exe -greset" to reboot.

Press F2 to enter BIOS you should (hopefully) be greeted with some extra menus...

Awesome! Thanks for posting! Can confirm it works on my Aero 15x v8 Smile

Do you have any tips on good settings to use for the 8750H?
I must admit I am a bit lost in all those settings!

Hello headkaze!

Really appriciate your work as well as Lost_N_BIOS.

Is this guide suppose to work (in principle) also with other version of Gigabyte Aero 15?

I have this 15W v7 (i7-7700hq+gtx1060) that I'm really interested in unlocking BIOS options for thunderbolt purposes.

The guide seems compatible but I'm not so sure about the PE32 image (is it suppose to be the same?) and about BIOS Lock variable too.

Hello headkaze, thanks for doing great work! the stock bios is very limited...

Im having a memory issue with my 15x v8 and was hoping that the unlocked bios will help me solve it.
I have been trying to get a a set of two hyperx CL15 hx426s15ib2k2/32 ram to work, thats 2x16gb. I have the same ram in 2x8 as well.
2x8=16gb total works fine at cl15 2666 dual channel
8 + 16 = 24gb works fine at cl15 2666 dual channel
This ram supports both jedec and xmp profiles, so it *should* work

I cannot get the laptop to post with one 16gb or two 16gb=32 sticks.
Ive undervolted with TS and have been thinking of doing this through this bios.
Do you think that i will be able to force the ram settings through the bios and get the 32gb ram recognized?
Thanks

Hey headkaze, I salute your abilities. This looked like a gift from the gods. but unfortunately your link with the sections to substitute (hosted by headsoft.com.au) is broken, and I understand it is very important to use specific files for specific machines.
Do you still have a copy of that archive?
Or maybe someone that previously tried to mod can pass me a link with the files?Please, me and my second hand machine are waiting for your help!
Congratulations to everybody,
Gabriel

Hello everybody. Firstly, I'd like to thank headkaze for the PM, as it made me able to successfully unlock the bios. Tons of settings that are making the laptop more efficient. Hands up!
Second, since I have a XPS9560, would it be possible to copy the sections of that bios regarding:
ADAPTIVE CHARGING
and
FN KEY LOCK
in order to merge it in the 15x FB0A bios? It would make this bios even more useful, but maybe this is an impossible fantasy. I'm not a pro, I'm just dreaming.
Congrats!
