[Solved] How to Unlock HP Insyde BIOSes

hey there Im using a hp g45 g5 laptop and I want to unlock advanced settings in BIOS.
so if I follow exactly what you have said will it work?

Hey! I’ve got HP 630 laptop aswell, and i’m willing to dedicate some more ram for my integrated graphics, since i upgraded my RAM to 8GB lately. My bios settings are locked, what can i do to unlock the setting for that? What other settings could be unlocked aswell? What recources should i read on that? I’ll provide any information needed about my system.


i need less vram to my igpu in a laptop g4 hp

yes thats what I want too
I need to reduce vram usage for my igpu

Can someone reupload for all three board models (3672,3674,3676) from sp53673 that already modded on advance menu and whitelist removed ?
Maybe @leolift or @theonlyjosh can share it ?
Links from @Lost_N_BIOS now are invalid.
Thank you.


Although I downloaded it once to make explanations in the duplicate thread that leolift’s request had already been responded to, I did not have his mod left.

But I have sp64612 modded.

You’re the Best my friend !!!

P.S. Russians are the best …

Here I can leave my oldest notes about the F.24 mod files (2015/16) …

If I remeber yet I didn’t check the RSA Lock bypass at that time, but now all is possible and also we know how to do …
I hope that these will be helpfull for you and for Lost_N_BIOS who has spent his life helping us all, many thanks firend !!!

Thank for your share @Sweet_Kitten
I’m surprised you already create mod for latest bios.

FYI, after running InsydeFlash then klik start, my notebook suddenly hang and flashing failed before erase/write process.
I have to unplugged my battery to boot normally again.
Any consideration for using your mod bios?



thank you for reveal it, is it using IDA ?

This happens when the BIOS is not for your notebook, but it is pointless in your case, because the BIOS is exactly for the HP 630.
For a faster response of the flash tool, I disabled the platform check by bios in the mod. It usually works, it seems like I shouldn’t have done it this time. I reverted the changes, but the flashing will start slowly.

The mod is available at the same link!

To "uwyref" , yes IDA Pro 6.3/6.5 (at that time), now 7.5.
To "Sweet Kitten" , You are fantastic, remade iscflash.4.1.6.1.dll patch and Setuputility, (RSA thanks to CodeRush and Donovan6k) and You removed comletly … Super :wink:


Thank you.
But after redownload your mod and apply it , found that problem still persist.

I have saw that it’s different approch to patch the dll file, so if do You want try this one …
We will wait the “Sweet Kitten” response, but meanwhile You have a chance to try :

https://www.mediafire.com/file/xysaj7bld…1.6.1.rar/file

Let us know
Regards

P.S. unpack rename as original and replace into mod servicepack folder, then run againf InsydeFlash

I’m giving a look to the code and for me this it’s enough to make the mod …

If so, then I have no clue what is going on.
But referring to the history of posts with LOST_N_BIOS’s mods, he might not have used the MultiFD function because he made mods for each platform separately. Perhaps this is the problem, and I shouldn’t have touched the .ini files either.
Also, @uwyref , does the original update from the support site work?



for about 6 hours ago i also have a thought about doing something on .ini files.
I try to get .ini from stock bios and successfully flashed.
After auto reboot my bios become stuck and have blinking A on keyboard
I have to debrick by HP_TOOLS from stock F.38 sp60723 (official hp site) using Phoenixtool.
Then i try upgrade to stock F.39 sp64612, it’s smothly applied.


I already doing this and still, my notebook suddenly hung after clicking Insydeflash start button



Can we have your mod version @BDMaster ?


This indicates that the BIOS was successfully flashed, but the RSA check patch for this BIOS does not work. And it also suggests that I still do not fully understand how things are with the methods of bypassing it. Now we at least know that the platform of your device is 3672 or 3674.


Let’s follow the same way of using the BIOS version before implementing this protection. Flash sp53673 modded as you already did it somehow with sp64612


Okay, after checking from entering bios info and many windows applications, it saying board type is 3673.


I confirmed this version (F.19.mod) successfully flashed, no issue when downgrade from F.39(stock) to your F.19(mod).
However ,I didn’t do .ini files replacement this time.

For hanging behaviour after clicking start i found that ‘unplug and plug’ (while AC powered) battery resolve it, keyboard and touchpad become functional again to click OK button then erase/write process starting until autorestart.
Entering F.19 mod bios, showing all mod are activated.

I use the same method ‘unplug and plug’ battery on your F.39 mod, didn’t succeed after all.

Maybe you can create mod on fully multi-FD F.39 @Sweet_Kitten

Thank you.

wow,I considered lost the advances for the bios insyde hp, I have an old laptop g4 2072la with bio insyde f 2nd revision dated from 2016 with this I can set the vram memory of my integrated gpu in 512mb?


did you mean gpu aperture size?
may be you will find 256MB to 512MB to choice
