To be fair I think it would be possible to write an EFI program to make the modification from booted external pendrive, but currently I'm overloaded with my real job, but I'm still planning to do it one day!
As with every bios mod I've ever done I would strongly recommend to

1) Gain experience with soldering, especially hotair for this case
2) Be confident when soldering on working device
3) Get eeprom/flash programmer (I'm using some chinese device, xegu) but you can always find a cheaper one compatible with the chip you're working on
4) Make a working backup...

I have one working board and two other with fried CPUs, which place do you need measured/checked?

Hey, last update.

I figured it out. Sorry it took this long, but I had to purchase another laptop preconfigured with NFC, and shipping it across the ocean with special help of customs office in my country extended it to only two months.
As I debated before FactoryConfigFlags had one byte set differently. The first byte should be '0x00' instead of '0x01' (see attached screenshot). Afterwards ther NFC module is detected correctly and works as intended (in UEFI and Device Manager).

Hope that helps anyone who stomps into this problem in the future....

Re: HP ELitebook 840 G8 NFC activation

Small update on progress: I wanted to see a clearer picture, so I looked for any kind of efi extension for ghidra, and I have found it. It's called [URL="https://github.com/DSecurity/efiSeek"]efiSeek[/URL]. After re-analyzing the two efi programs I have found, one of them is indeed electronic label renderer, but the other one happens to set the NfcOptionImplemented container and locate/load some protocol, based on what it finds in FactoryConfigFlags container. The algorithm is a bit obfuscated, and uses RAM addresses to load a few...

Hey guys,

Recently I've been working on a laptop I've bought for myself, repaired water damaged board, and wanted to add few nice things. Fingerprint sensor worked just fine after installation, however the nfc chip is a stubborn one.

(I also happen to have an old 850 G3, where the nfc activation happened in ME branding stage with [URL="https://www.badcaps.net/forum/showthread.php?t=69204"]nbdmifit tools[/URL]) but the tools do not even recognize the status of "NFC" as its probably outdated for this platform.

I have some previous experience...
