I don't check at the SLIC log, you can tell by BIOS name .DEC after it's done unpacking BIOS, and or BIOS size after unpacking the exe yourself. This BIOS is encrypted too

F12 can't be oldest, maybe only oldest they have linked on site now, I bet you can find older in google. What is different SP name? Different model? If yes, then it's not your model, so success there or those BIOS do not apply.
Or, those users originally had non RSA BIOS before flashing that BIOS, and you are currently on RSA BIOS, so you need BIOS before that first, then flash/program

Hi

it seems I have found a older one, can you check sp54846.exe
Also read some about F19 "cracked" rsa bios, but unable to find it blog don't press download link get's you no where.
"this is a gift from Donovan6k Bios Mod F.19 RSA Hack sp57474" that one I can't find

let me know :)

do you mean by "so you need BIOS before that first, then flash/program" that after I have f02 running I can flash to newer modded ?
like this user ? :

Update the link, please.
If I get you right:
1. First you need to install F.02 Patched
2. Then install F.1C bios Mod

Yes, that is what I meant, you have to flash older BIOS non RSA, then you can program in other BIOS later easier.

Thanks for the blog link, maybe I can eek out some info from it. That EXE BIOS you linked is encrypted too, it's the same BIOS from sp60655

via windows ? otherwise I don't get it, via the programmer I flash a whole bios, with or without rsa check in it.
how can I or do you check if is has a inside rsa check ( besides from the insyde flasher, because all is encrypted) ?
I also find f1 ftp://ftp.hp.com/pub/softpaq/sp58501-59000/sp58987.exe

it is possible that you make a f02/01 rom with disabled gpu from the bios I gave you? and flash it via the programmer to avoid downgrade issues. ( a complete rom )

meanwhile I will try to get a old one stock from hp in it....

Use programmer, main thing is first finding an older non RSA BIOS if there is one for this model. BIOS is decrypted when we would edit or look at it, or program it in, so encryption is not the issue it's the RSA Signature check internally.

I do not know what you mean about f02/01 ? We don't have any downgrade issues, only RSA signature check stopping booting at startup.
Ohh yes, that blog, I think he's full of shiiii you know, all that talk, to himself, never shown any results, only wow he got programming tools, then disabled comments and leaves knowing we'd find later along with 1000's of others.

The exe you linked is newer (2012) than previous one, which I just noticed is the oldest one you linked so far (2011 - sp54846, encrypted so likely RSA too, but we did not check by edit/program)

haha I agree no detail was provided

I have made read out of f02 can you make a test modify ? Rename a tab for example
if that fails I will give up , I do not see any other options.

thx

lol I changed to hp logo for own and that did work :)

laptop still boots but does show extra gpu

so I guess this is moddabble!

@Lost_N_BIOS do you have the skills to enable advanced menu on the bios above ?
I have tried to clone youre settings/mods from the new bios to this old bios, did boot but still can see the amd gpu in windows

Thanks @jeroenvtec - I will make same changes two ways and we'll see. Maybe only certain regions protected, since you changed logo and it was OK?
Or, my method of change is causing non-boot, but I more suspect RSA, since I use these methods on other HP non RSA without issue, that have same BIOS style/creation tools etc.

What did you change logo with, Insyde tool or UEFITool? If inside tool, open your mod BIOS in UEFITool, do you see any CRC32 error in parse/comment section?

@jeroenvtec - Quick test first, please check so I can move forward with FD unlock applied or not. Does this cause failed boot?
http://s000.tinyupload.com/index.php?fil...721506548262901

yes the logo but also module FE3542FE-C1D3-4EF8-657C-8048606FF670_714.ROM based on your earlier mod so I have confident in this one (the older f.02 sw) !
I used insyde tool and phoenix in combination with a hex editor..
I used windows inside to flash it btw

I am on in t!
btw the FD unlock did also work on the earlier bios file.

@jeroenvtec - Good FD unlock is OK, this means once you get a working mod in there, you can use FPT instead of programmer. All BIOS below have FD unlocked and your desired setting changes, so once you find one working and use that last, after that next changes you make can be flashed in via FPT if you want.
Here is four BIOS to test, please test program in each one, don't stop if settings you want are there/applied, please test all so I know method needed to be used next time (on final edit, we will make BIOS settings visible to you in BIOS so you can adjust as needed)
http://s000.tinyupload.com/index.php?fil...591436250096846

You used all those tools, great! You're picking it up now! I noticed when using Phoenix to edit structure or save/Go mod BIOS, it removes a padding file, so I have two in there to test about this.

*Edit - Please check with HWInfo64, or other tools like AIDA64, GPU-z, PCIE-z etc and see if you can find which port (1-4, ports 5-8 already disabled) the PCIE AMD is on, then we can disable that port entirely.

YES !! I got it
cloned some hex settings from other HP bios. And off course the help of Lost_N_Bios
Now got advanced menu and I am able to disable AMD gpu

Great you got it! Now, two things, please tell me outcome of BIOS I posted above, so I will know method to use in fixing BIOS later for others, hope you don't mind, thanks!
This will also maybe help us decide/find out if previous edits were bad causing the non-boot, or if RSA was the issue.

And then, tell me what you did you were just excited about that fixed the menu's for you.

yes sure, I will test that later, first test the laptop with some new installs.
I am sure this has to to with RSA check in the bios, as extra from the flasher btw. This old version does not have that as you prodicted.
used andy tool and modified windows inside flasher, mod based on hp sp55068 bios. There I had stock and modified version of it. So I programed nothing I was lifting on others work.
oh I also followed this : https://web.archive.org/web/201410100455...power-tabs.html

I believe:
Advanced > Video configuration > special features to disabled and , internal grap dev. to (rc6) disabled. rest is untouched, regarding the video.

Wish would be a newer bios but ok, result are here now.

YOu may be able to use a newer edited BIOS now, programmed in, you'd have to test that but after we figure out results from my BIOS above so we know which method is proper way to do it.
Thanks for the info, I will look into all that tonight. I see NOP NOP in your image, bypassing some restriction at an original JZ/jump location, so I do recognize what's being used there (in assembly)

can you explain that a bit ? on what way is there rsa check then skipped ? it's in the flash bios right. So then I don't understand why it would work, via the windows flasher or the complete rom via the usb programmer.
Yes correct it seems al the magic is done in FE3542FE-C1D3-4EF8-657C-8048606FF670 for the this HP serie

What I do understand is if you disablete the signiture check a mod bios will work for this laptop types.

what tools do you use btw ?

edit:
did the same with fb1 (newest) and that gave a blank non bootable laptop
