It's better to use the current dump, because it ensures that none of board-specific setting and/or user setups will be lost.
It also won't enable flashing without the programmer, but will enable modifications of DXE volume.

Oh I see, makes perfect sense. I should first purchase a programmer then, thank you.

Hey. I have exactly the same laptop as you. HP Laptop 15-bw0xx. BIOS InsydeH20. I also follow the thread of this topic, but I understand almost nothing, sorry, I wanted to know, in general, theoretically, there is an opportunity to open a tab advanced in BIOS InsydeH20 on HP ? I just wanted to tighten up a little bit. add GHz. in technical support HP I was told that this is impossible...

It's not an unlocked model, therefore there is no way for overclocking. You may check for your cpu here:

@CodeRush - Thank you so much for jumping in to help here

Yes, nothing hidden that's really interesting here to unlock in the BIOS menu, especially not CPU/Memory OC related

@CodeRush
Unfortunately, the changes didn't work.
When I flashed the bios with the rsa bypass (with the changes you suggested) and tab unlock (my attempt), the notebook turns on but screen remains off, the capslock key blinks 2x indicating bios failure.
I flashed it many times just to be sure I wasn't missing anything.

I successfully flashed the bios of this same notebook multiple times (with stock bios), so I don't think there is any problems with the programmer+clip or the flashing process.

Is it even possible that my attempt to unlock the tabs is the source of the problem?

This what I changed to unhide the advanced and power tabs:

This sequence only has hidden tabs. Seems like this is some sort of blacklist.
I removed the "Advanced" and "Power" references and replaced them with the other ones that I don't care about.
While of course this is just a guess, this is the only part of the code that made sense to change.
This is the menu module unchanged: http://www.mediafire.com/file/kizvfxk33e...fitool.bin/file
I tried following some other methods but the code is very different.

I will only able to test anything more next week.
Any help is appreciated!

@Kirfve, can you please send me the original and modified dumps (via PM)? I'll check the mod to be done correctly, because modifications of PEI volume can be tricky, and sometimes tools fail to perform them properly, making a resulting image unbootable.

Yes, I suspected that menu mod may not be correct. To test your RSA mod bypass attempt, you need to make some other simple known "should be OK" edit, like update a microcode manually

@CodeRush I think we can continue the conversation here since the bios being used to test is a stock one.
I understand this is a difficult one to crack. If you don't want to, or don't have time to help furthermore, I completely understand!

This serves as an advice for anyone who has a HP notebook with rsa protected bios: Don't even bother with modification until you know the protection on your⁠—specific⁠—bios is bypassed.

It's not really difficult one to remove the check, it's much more likely a structural breakage of the modified image, or maybe some countermeasures by AMD that we aren't yet aware of. I'll check it out once again when I can find some spare time.

Just an observation, because I "hijacked" the thread from the start and our notebook models are different: My model number is v066br. The thread starter notebook has an amd cpu/apu but mine has an intel cpu.
