is there a way to unlock the bios for the new aero 15 xc laptops?

@rezzy_s thanks so much for your reply and advice!

I might start to try undervolting it tonight - but I am scared of making mistakes with the BIOS flashing!

With your undervolting did you see better temperatures during gaming and normal use?

Thanks again for your help!

@schrumpelrat I guess it will be possible by doing the same steps others have taken:

STEP 1 - dump your current BIOS
STEP 2 - unlock flashing of your current system
STEP 3 - edit the dump of your current BIOS to unlock settings
STEP 4 - flash the new BIOS

I'm a total beginner and am just learning myself so be careful and do your own research!

Sorry to post again in this thread so quickly.

This is the system I want to undervolt:
AERO 15 KB-7JP1130JH
i7-10750H on HM470 chipset
RTX 2060
144hz Panel

These are the steps that I understand that I need to do:
STEP 01 - Install lastest BIOS from manufacturer. Dump BIOS and archive it.
STEP 02 - Provide link to BIOS from manufacturer to @Lost_N_BIOS. (help with variable to unlock BIOS region and unlock BIOS itself)
STEP 03 - Unlock BIOS region with variable from @Lost_N_BIOS.
STEP 04 - flash unlocked BIOS.

Is that correct?
I'm concerned that all the guides and programs are for older models (HM370 chipsets, my model is on a HM470 chipset).
Can I still use to older guides (particularly when unlocking the BIOS region) with my newer model?

@Lost_N_BIOS
Sorry to bother you again. Is it possible to tell me the variable to unlock my BIOS Region?

Thank you for any help possible!

Hi @Lost_N_BIOS

Sorry to bother you again. I have been reading and researching! I hope to unlock my BIOS now! :)
Any help you could offer would be much appreciated!

I dumped my BIOS.
It can be found here: http://s000.tinyupload.com/index.php?fil...329893849923525

Now I will try to unlock BIOS flashing. Can you help me identify the variable that I need to change to unlock the BIOS Region?

Any tips for an AERO 15 KB (no OLED) would be much appreciated!

EDIT: Disregard

@rezzy_s
How did you unlock your BIOS Region? Using RU method?
Also, what was your variable?

Our systems are similar so maybe it can help me.
Thanks!

I'm trying to do a hardware upgrade of my Gigabyte AERO 15 SA (i7-9750H).

In a few words :

- Adding of one new 8 Go RAM module (in addition of the OEM 8 Go ram module) : SAMSUNG SODIMM M471A1K43CB1-CTD

- Adding of a second 1 to SSD M2 NVME (250 Go on the OEM M2) : WD Blue SN550 NVMe SSD 1 To

Tests report :

1) First try :

- Black screen on laptop startup

2) It seems to be a RAM problem, so I giving back RAM to OEM configuration :

- the BIOS seems to go further (GIGABYTE logo on screen), function keys reminder but no OS boot and I can't access to BIOS setup (F2 key doesn't work...).

3) I giving back SSD slots to OEM configuration

- laptop is working normally (OEM configuration)

I tried with and without Trusted computing enabled.

new ram module and OEM ram module photos in attachment.

Could you help me to solve the problem please ?

Hi!
I'm not an expert with laptops but have some experience with desktops.

Start by just changing one thing first and testing. This will help to find the issue.
First reset you BIOS back to factory defaults and then try changing things.

With the RAM:
Have you tried booting with only the new RAM installed?
If you have problems with just the new 8GB RAM installed then you probably have a bad stick and need to send it back for a replacement.

With the HDD:
I'm really not sure here why this would be happening. Sorry. I hope someone new else can help.

@Jimmyme Yes correct. I had to use the RU method, since the other one didnt work. If you go on page 4 of this thread Lost_N_BIOS mentioned these steps. I think it is is around the #203 reply.

@rezzy_s
Thanks for the reply!
I have prepared for RU method.

I just checked reply #203 in this thread. So you changed this variable: (4570B7F1-ADE8-4943-8DC3-406472842384) at PCHSetup?

Thanks for your help. Our system is same except for OLED display. I think this can work for me too.

@rezzy_s Thank you very much for your help. I managed to do it! :)
BTW, does Windows 10 install BIOS updates automatically on your system?
I think it might do that on mine. Did you disable it somehow?

@Lost_N_BIOS Could you please unlock the menus in my BIOS?
Of course, I would be most happy to donate to you and the site.
Thank you in advance!

I used RU to edit the BIOS. Then dumped it in windows and reflashed it. No errors.
Here is my region unlocked BIOS: (REMOVED)

EDIT: I will remove the BIOS file until I hear something from @Lost_N_BIOS or another user who can help unlock it.
