Dell G5 5505 SE TPM Attestation Failure
Good afternoon,
I would like to report an issue for the Dell G5 5505 SE. There are some games like Call of duty Black Ops 7 which require a higher tpm manufacturer version for example 3.92.5.2 (because of an amd firmware issue that causes TPM attestation to fail), otherwise its blocking me from playing modes like ranked. The issue is this can only be resolved from a bios update and there is not a new bios update since 2024. Could you please release an emergency update for that matter?
Thanks

I will just upload a download link for my bios dump with some instructions, since dell refuses to release an official fix and its the only known solution to fix TPM attestation issue on Dell G5 5505 SE (also adds support for resizable bar up to 8gb bar size).

The Inspiron G5 SE 5505 will not receive an exception BIOS for this 2025 released game issue.
The Dell computer platform teams have released a final statement.
The models shown below will receive an exception BIOS for this 2025 released game issue =
Alienware Aurora R10 Ryzen (internal i-rev BIOS release only)
Alienware Aurora R14 Ryzen
Alienware m15 R5 Ryzen
Inspiron G15 5515 Ryzen
If your model is not listed above, then it will not be receiving an exception BIOS.

According to AMD, here is the article:
https://www.amd.com/en/resources/support-articles/faqs/pa-420.html
Dell was aware of that issue since 2022 which the G5 SE was still receiving bios updates till 2024. So its not an issue that appeared in 2025, either way if thats true and nothing changes im extremely disappointed.

By looking it a bit further:
1) Your answer is wrong you mentioned some Intel based PC's (Inspiron G5 5000, Inspiron G5 5090) which this is not an issue with Intel motherboards (and then you edit it?) so i believe that was not an answer directly from Dell.
2) The Inspiron G15 5515 Ryzen edition support has also ended but still received a bios update for that matter.
So could you please transfer that message to Dell computer platform team or in general the team that is responsible for those issues to release a bios update?
