Z440 Workstation. TPM wont update

[Hammer331]

Wow!  That’s great!  Thank you for your help.  Let’s hope they can provide a solution.  Just so strange their softpaq doesn’t work.  I wonder if there are different versions of hardware.  

Thank you!

Hi, any updates on this?  Would be great if someone can share detailed instructions…even if it’s a bit of a hack to get it to work!

Thank you!

Any Updates?

It was suggested by an SME that you try disabling the TPM and then applying the update software and then enabling TPM.

Which specific Z440 workstation do you have?

I notice that the supported operating system for the TPM upgrade software is Windows 10 and below.

I extracted the TPM update software and found a document that has a list of supported platforms at the end of it.  It is worth a read.

HP Z440 Workstation Long Life,  HP Z440 Workstation LL are supported, although they may be the same. 

It may be worthwhile for the others who have chimed into the thread to take a look as well to see if their workstations/desktops are supported by the update software.

I have provided the document in this reply.

It still does not work. My TPM in my Z440 needs the exact bin file name TPM12_4.40.119.0_to_TPM20_5.62.3126.0.BIN and also the messages are always the same. "The TPM firmware update was prepared successfully. Select .... "
But its not flashing.

Hello all,

I had the same problem with an z640 and a z440. I had those for a few years and managed to update the TPM on both of them effortlessly a few years ago. Due to a stupid action I had to swap the mobo's on both of them. The new Mobo's both still had the TPM 1.4 firmware.

So I updates all drivers and BIOS and at last the TPM but that didn't work anymore. Hmm strange no? After a while I started to think that was no coincedence and could only be caused by the BIOS. So I tried to roll back the BIOS in the conventional way. Turned out that didn't work either, hmm. Via the BIOS with a bin file on a sticky did work. So I rolled it back to 104013 (oct 2020). And YES, the TPM update worked again!

Sorry, See now that I repeated my former message. Can't seem to delete it.

I have been told by HP SME's that it is likely to be a hardware issue.

If your laptop or desktop has a TPM 1.2 chip, updating it to TPM 2.0  by using firmware upgrade software is not possible.

I do not have an answer as to why HP provided the TPM upgrade software.

I asked about that and have not been given an answer other than the issue is a hardware generation problem.

I do wish I had a more concrete answer to give you, but this is what I got when I asked  the HP Subject matter Experts.

Hi, I have 2 Z440 workstations. On both win 10, GPT, newest BIOS. I cannot upgrade it to 2.0. Same issue as original post. 
All seems to be ok, but there is no flashing, computer just restarts. I would be very much interested to find a solution for it.

As mentioned applying the latest BIOS to tthe latest version might be the cause. Did you try the TPM update after rolling back the BIOS to somewhere three years ago?
