Tell me PCI ID of the original WWAN card.

Tell me PCI ID of the original WWAN card.

I don't have one installed, only an empty slot. According to service manual it should be HP part number 531993-001, it's quite common in HP laptops. Maybe you can get PCI ID from web or this image:



If not, thanks for the effort.

I have uploaded testfile for you, i must warn you that many probook laptops doesn't accept the modded bios and automatically revert back to original bios, so if yours does this i cannot do anymore to solve.

Flashing is safe, even if it bricks the laptop, recover from bad bios is child's play using a usb stick.

Look for your test file following my signature directions, second HERE.

I tried your modded BIOS, but unfortunately it doesn't work.
I get 'The System BIOS update failed' message immediately after pressing Enter to apply update (after restart), it doesn't even start writing the new BIOS.

EDIT: Nevermind, I saw in another post I have to remove hptools partition, I'll try this later.

Nope, doesn't work, bricked it. Managed to recover after many unsuccessful tries.

[camiloml]

This happens a lot with Proobook and Elitebook laptops. Or reverts to original or it simply bricks but always are recoverable by usb stick and original bios.

So it's impossible to remove whitelist for my model?

[camiloml]

At this moment ... i think so.
