XPS 15 9550 - TPM 2.0 upgrade failed "blocked by tpm fw policy"
Hello All,
I have Dell 9550 with 1.7.0 BIOS. I need upgrade TPM from 1.2 to 2.0 module. Always I got a message "Failed blocked by TPM fw policy".
I try everything:
- clear TPM via BIOS
- clear TPM via Windows option
- disable auto provisioning
- upgrade via Windows
- upgrade via DOS mode from USB
Do you have any ideas what wrong with my computer? Any helps?

Thank you for your answer, but this manual doesn't help me :-(.
I think this is something wrong with BIOS.I downgrade - it doesn't help.dgabriel

Any luck with this? I have a Optiplex 7050 and I'm getting the same blocked by TPM FW policy message...

Have you checked what TPM version you currently have? My XPS 15 9550 has v1.2. I don't know if you can run a v2.0 update on a 1.2 TPM chip. You can convert 1.2 to 2.0. There are updates for both versions on the Dell Support site for the XPS 15 9550. Dell gives no indication as to which one you should use. Also Dell gives a rather involved process to run the update. Is this something Dell Update presented to you or did you manually download it?
