I think these firmware are incremental rather than full, and FIPS firmware is different from common criteria, so we can’t simply modify the version number to install incremental updates.
By the way, I didn’t found the downgrade 1.2 firmware for FIPS.
Maybe you have the truth, I don’t know if it is incremental.
This is a screenshot trying to modify the last version number.
I’m very lost with this…
I need fw 5.63.3353.2
this key are “2”
I want a modified TPM.
I have TPM20_5.62.3126.2 but I wish to upgrade to the latest TPM20_5.63.3144.0
Can anyone do a mod for me PLEASE? → (Like: TPM20_5.62.3126.2_to_TPM20_5.63.3144.0.BIN)
Note: UEFI Tool does not help. “UEFI volumes not found” error appears. 
With HxD it is not possible to grab a single file inside the .BIN file of: TPM20_5.0.1089.2_to_TPM20_5.62.3126.2.BIN, TPM20_5.51.2098.0_to_TPM20_5.63.3144.0.BIN etc.
Seing this post of yours last year…
Isn’t this an offboard bought TPM module? …
You downgraded, now you’re back 2.0…isn’t the FW in the module itself, why are you opening the main bios image with UEFI tool, this is no tool for such data, the TPM one.
Why looking for TPM fw in main bios image…

You are right. This one is another Chinese TPM module, for another x99 mainboard not for x79.
I have many but 2 type TPM modules for MSI, Asus. I have managed to remove MSI 14 pin TPM 2.0 chip and soldered to Asus 20 pin type. Seen it works revision was TPM20_5.0.1089.2 flashed to TPM20_5.62.3126.2 I have bought this MSI TPM 2.0 module for pin modding earlier. Tried changing pins for Huanan dual processor X99 but did not succeeded.
I have also 2 unused TPM 1.2 for MSI. Bought one for Z77A-GD65. But there is no TPM menu inside the Bios menu of this board suprisingly, I couln’t use it. Other TPM 1.2 module was for MSI Big Bang Marshal, it was fine. (But one of Ram transistor chips burned, I have no chance to try after ordering.) I may think removing one of their chip later after trying a lately purchased one, that is an Asrock module.
I have seen an 18 pin Asrock cheap second hand TPM 2.0 module, asked TPM version but seller does not know. I will remove the chip and see what it is soon.
“why are you opening the main bios image with UEFI tool, this is no tool for such data.” I have not tried to open bios image, I have tried to open the BIN file of TPM image such like TPM20_5.0.1089.2_to_TPM20_5.62.3126.2.BIN, yes maybe was a stupid act.
