Bios Mods -The Best BIOS Update and Modification Source

Hi.

I have a Dell Latitude G3 3579 LA-F611P (this was a storage and was a bit outdated); that was running an old bios (below 1.8.0), and all was working good; after windows update, it updated the bios to the latest version (1.20.0), and now every time I turn on the laptop I get an error about TPM, saying “Alert! TPM device is not detected.”

I have attempted a few fixes, like CMOS reset, bios settings, bios downgrade, but I can’t get it to downgrade below 1.13.0, and even on 1.13.0 the error still shows.

I have seen online a bios MOD that disables the “TPM Over SPI Bus” and that “fixes” the error; unfortunately, I can’t get my hands on the actual bios (VIP download).

I have enough knowledge to do a dump of the bios and flash the motherboard with a mod bios; but moding the bios is beyond my skills.

So, my question is, would anyone please help me mod my bios so that the TPM is disabled and/or at least the error is hidden (because even if I hide the errors on the bios settings, that one still shows up).

Bios dump.

Thanks,
Dia

Hello, I have the same problem in dell G3 3579 as you tpm error.
After removing the motherboard, it turned out that there is no TPM chip.
I called Dell but they don't care and they keep releasing tpm motherboard patches.
Where did you find the modified bios version, please provide the link.
Maybe he will guide me, and maybe I can help you
Regards

The site on which he found the mod is likely a scam, because TPM Over SPI Bus is disabled even in the untouched BIOS backup. This setting does not apply to the error bothering you.
