[Request] ROG Strix G15 Advantage Edition G513 (AMD)

-------------BIOS MOD/FLASH UPDATE------------

H34T0 and I are still working on getting one of these G51X notebooks flashed. We have made some research progress figuring out the type of chip that these notebooks use. It is non-standard in that the pins are flat against the sides of the BIOS chip instead of legs that kick out from it. This and the fact that the chip is non-standard size as well (6mm x 5mm) makes it so that we cannot use the standard clip that comes with the CH341A programmer or other same-type clips like the Pomona 5250.

We have found an SPI adaptor that meets the CH341A specifications and fits onto the chip. It is one that you will have to hold on top of the chip. They seem to cost $20-$30 USD, unfortunately. But once we get our hands on this, we will be able to test both the connectivity and the voltage modulation requirements. The voltage modulation that this chip requires to draw enough power to perform read/write operations will be fulfilled using a pull-up resister.

Further updates will be posted as we discover more. Once we (hopefully) get a successful BIOS flash, full and detailed instructions will be posted and I will offer BIOS mods for everyone on this thread and future requesters.

Thanks for the update. I wonder if this will be the same for other machines like the 2022 GU603ZW.
Thanks

How is it going? I'm waiting eagerly for some updates.

How is it going? I'm waiting eagerly for some updates.

H34T0 and I aren't going to be able to get ahold of the necessary hardware until probably some time in March, and that even is dependent on the situation in Eastern Europe right now. In terms of hardware, I mean something like this that will fit onto the non-standard WSON8 6mm x 5mm BIOS chip that these notebooks use: https://www.aliexpress.com/item/40001080...rrency=USD (There are cheaper versions elsewhere, but I don't remember where)

In the mean time, we are looking for ways to get around HMAC authentication on the BIOS chip if it is implemented. Pages 7-17 of the attached document describe how HMAC authentication would work IF it is implemented. To be honest, I have no experience bypassing such a mechanism as described. We are hoping it is not implemented but doing research in case it is when we are ready to begin flashing.

Hello @SML6397,

I discovered this topic. With new driver RSR, i hope to have access to advanced option for enable only dGPU on this laptop and disable igpu. Also disable AMD CPU Boost & other stuff.

You can provide to us , a quick update ?

Thank you and have a nice day.

Hello everyone,

Apologies for the long wait, but I have great news!

@H34TO and I have discovered how to hardware flash the G513 series notebooks!!!

Really, it was H34TO who discovered who to do so. I provided moral support . I believe they would better be able to explain the process that I but essentially it involves using a 1.8v converter board, a properly placed resister of the right impedance on the CH341A flasher, and a hand-held SPI chip adapter (to deal with the unusual chip size/shape).

We have tested a basic Chipset Menu mod and it worked! We are in the process of testing various other mods with goals to unlock the CBS/PBS/AOD menus and more. The CBS/PBS/AOD menus willll take some time as I study up more on assembly. These three menus are not linked into the AMITSE module with the rest of the menus so it is a matter of getting the BIOS Setup Utility to read in those extra external modules via some link somewhere in the code. I just need to find where to put that link.

@H34TO, you want to take it away with the how-to on hardware flashing?
