[Requests]HP Pavilion g4-1000 Series For UEFI

[gujiangjiang]

Hey gujiangjiang,

It looks like you are able to recover from a brick, so would you mind test something for me? Try flashing all four of these roms. Let me know which ones brick and which don't. This'll help us determine which bios are moddable and which are not. Thanks!

Hello donovan6000,
My BIOS can't be recoveryed,i try all method to recovery it but faillure.Finally,i just remove bettary for CMOS and wait 5min ,when i turn on the laptop,the screen display following word:

The CMOS checksum is invalid.
The CMOS will be reset to the default configuration and will be rebooted.
Please check your BIOS Setup options to see if they changed.
CMOS Reset (502)
ENTER - Reboot the system

Then i press enter and laptop reboot byitself,and then it can boot into desktop,so i flashed the offical BIOS from HP website.

So the laptop was final now but i still can't recovery it by using U-Disk or HardDisk.

Then

Your Four files i will help trying to flash it ,and i will report here.

Thanks

Regards!

The DLL was replaced in origial package,so there is no need to change DLL file.
PS: I checked the HEX between two DLL ,and i find they all same.

So i think the brick is not be DLL problem.

Be very careful then if your not able to get the normal USB recovery method to work. I don't want you to brick you laptop

Also, what could you not get working with the USB recovery method?

I also want to know

I try to make a hp uefi inviroment and put 0166c.bin & 0166c.sig to current ,then press win+B,but when i turn on the laptop,he SCAP was flash twice a time,the WIFI was red,the Fan doesn't run.

F15、F23&F24 are OK .F32 is brick.

Thanks for testing those. That really helps validate some of my ideas abotu RSA bios

I never said I unlocked any tabs. I just changed 'Main' to 'Nain' because I wanted a quick way to make the rom would fail the RSA check. Now we know the bios for your computer made before F32 are moddable and all after and including F32 are not moddable. That's pretty good since before we could only guess which of the 16 bios released for your computer were moddable

Did both you and your friend manage to unbrick both your computers?

I'll upload a modded F.24 in a couple minutes. Thanks again!

Here you go. You'll find an EFI boot setting under the system configurations tabs. Eventhough this setting exists, I've never seen anyone successfuly get EFI working perfectly on one of these older HP laptops. Insyde and HP decided to remove a lot of EFI functionality. All we can do is unlock options, so if it doesn't work then there's nothing we can do about it

And try to come back to this forum during the next couple of days. I have one more thing I want you to test regarding RSA bios modding. Hopefully this test will be able to dtell us if the signature verification check is in the PEI or DXE region of the rom

Helllo donocan6000,i test the ROM,works fine,but have some mistake.
1.    
Look those Square between the menu...

2.UEFI Boot might not work even turn on the EFI Boot.
I think,Can anyone add the EFI Modules to this BIOS to become EFI Boot.

Thanks.
Reagrds!
