How to force flash/downgrade HP ENVY - 17-s143cl BIOS version (willing to pay)
#1
Hello, recently I just upgraded my BIOS version to the newest one, which is F.97 Rev.A, and now I am experiencing many issues, so I want to downgrade my bios back to my original one (F.82 Rev.A). However, when I download the older version from the site, it does not let me. It says "BIOS update is not compatible with this device". Then I tried to to the Windows Key + B method with the correct files, it just says "Bios update files not found." Is there anyway I can bypass this and force downgrade my BIOS? Thanks![Image: 1681420044739-png.2609763]
Here are the files https://support.hp.com/us-en/drivers/selfservice/hp-envy-17-s100-notebook-pc/12499196/model/12780775?sku=X0S43UA&serialnumber=5CD6494DGN

Hello.
Try the patched flasher.

Extract the archive, put the binary files of bios version on your choose in the same dir with the HPFlashWin flasher. Make sure the binaries renamed with .FD extension.
Run HPFlashWin, click Browse FD File and choose ANY VALID bios file.

Hello, just curious tho the binary files mean the 2 file we get from copy bios file right? it's .bin file and .sig
I tried to rename them to .FD and the hpflashwin just crashed after I click next. If I don't rename the files, it will show menu update, make USB recovery and copy but all the option is disabled.

Yes. Those are good. sig file is not required.

(04-15-2023, 09:08 PM)Jacatinelord Wrote: the hpflashwin just crashed
Another version. It should not crash and show legacy (Insyde default) flasher view in any event.

This is not a compatibility issue. The error appears when the program can not detect your current BIOS' FID and version.
I saw your post on overclock.net and the battery disfunction just after an update confirms that the BIOS is corrupted.

HP notebooks have 2 BIOS update modes: 'Legacy' and 'by UEFI'.

The first of them is out instantly, because InsydeFlash doesn't work with AMI type, which Victus is supplied with. I had no luck patching flasher program for AMI. BIOS gets corrupted.

The second is possible by shell flasher program, tbh the same for all HP notebooks. But it is not an option either. Although there's a way of starting HP Bios Image Interface without request from updater program or Win+B combo, the shell flasher wants something else than "CryptSHA1" driver being loaded for proper work.
So, patching shell is currently meansless.


I think you should get your device to a repair shop.

Yea, i am worried something wrong with my hardware because the GPU need to be undervolted in order to use it on AAA games, if not undervolted it will frame drops, its happened after my bios corrupted (Win 11 include BIOS update  Confused ) and trying to recover it with the lastest version anddd somehow its like throttling now. Hopefully hardware is good and software is the problem, I will try visit my official service center again soon, because last time I visit them they likely did not get what the problem is xd

Thankyou for your time and these explanation!

Hi Maxinator, thanks for your reply! I did what you said and everything worked fine, but now my laptop won't boot and the caps locks is just flashing. I think I may have bricked it. Also I selected the "just write BIOS version" instead of legacy flash.

It might happen because the chosen version was too old. For a very outdated version it is recommended to do sequential downgrade.

Try to power up your device along with Win+V being pressed, or perform recovery procedure.

What do you mean by that? I don't remember options in flasher named like that.
