(Locked) BIOS LOCKED HP ELITEBOOK 8470P

[chupameucuzin]

Goodnight!

Friends, so I had the idea to install WIN11 to test, and it asked for TPM and to activate TPM I had to put a password, since then I forgot the password. I would like to know if it is possible to circumvent this password or break it without having to touch the motherboard? I was watching some videos and I came across this picture situation.
Does anyone have a file similar to the one in the image that releases the BIOS without having to touch the motherboard?



The BIOS has the following boot options


Pen drive
enter by card
Windows Manager Boot

But every time I try to put something on the flash drive, I can't run it, sometimes nothing happens and many times it gives "error loading image invalid file".


Something I've been thinking about and if it would also be possible to force a BIOS update even with a password through HP's HPQ program, would it be possible to bypass the part that asks for a password and forces an update with some bypass?

Junior, thanks for answering me!!

Just had a problem, like this appeared SMC Failed

This SMC that you made available, needs to play on HPUnlocker, right?

I played there, then it generated a file, this file I renamed to SMC.BIN but it gave a reading error

In the case of the Elitebook 8460P is it for the 8470P? I forgot to mention that my BIOS is updated to the latest version of 2019

You didn't attach your bios, how do you unlock it?

I see, so I can only unlock my bios if I have a backup of it, right? The problem is that I don't have a reprogrammer to take the BIOS backup. Is there any way I can get the backup of this bios through windows? Or is this only possible with the removal of the chip?

For a cheap programmer, such as CH341A, removing the bios chip from the motherboard is necessary. For more expensive programmers there is no need as the clamp can be used to connect the bios chip and the programmer.
