I'm coming from here...
win-raid.com/t9605f2705-REQUEST-MSI-A-G-PLUS-TPM-SUPPORT-MOD.html

Since I discovered all the issues with TPM versions, now I need to mod .bin file to change internally version number and bypass flasher messages to make a downgrade.

There is any tool to make it possible? I uploaded the file to help searching the answer.

Edit by Fernando: Thread moved into the "BIOS Modding Request" Sub-Forum and thread title customized

Hello Fernando:

I will try it. Yesterday I modify the version number with another editor but Infineon flasher identified it like corrupted file.
There is any trick to avoid this issue?
I'm not an expert on this area, but I will try with HxD tool.
Thanks!

Thanks @Fernando this is very useful

Only have to say that I have not to modify the BIOS-UEFI (this time). This firmware is from TPM 2.0 with Infineon chip. My motherboard is a MSI 970A-G43 PLUS with TPM 1.2 support and physical module head. I have two possible scenarios:

1- Modify the UEFI and get support of TPM 2.0 (but MSI says to me bye bye , and the info I got here in the forum says that is virtually impossible to insert the TMP 2.0 BIOS module or code from another MSI motherboard product).

2- Downgrade the physical TPM 2.0 module firmware to get 1.2 full support with this board. Issue is that I'm on a "special" firmware version and I need to modify one number on the version to make the downgrade possible.

I need help. I don't know how to correct the checksum in a binary file...

I changed two values with HxD, only two numbers (red colour).

@snowind:
As you can see, I have moved this thread into the better matching "BIOS Modding Requests" Sub-Forum. Furthermore I have customized the thread title. If you are not satisfied with the new title, you can change it at any time by editing the start post.

You have the file on post #1 and modification needed on #7
Thanks a lot

@Fernando
Sry to steep in... i do believe that the user has problems with a modified BIN file of a TPM module FW that he owns and was flashed at his own will, based on shared info from another user, its not a bios file.
The user can correct me if im wrong.

Initial post from user: (REQUEST) MSI 970A-G43 PLUS TPM 2.0 SUPPORT MOD

Shared info by another user: (REQUEST) MSI 970A-G43 PLUS TPM 2.0 SUPPORT MOD

@MeatWar not exactly.
I bought a TPM 2.0 module, and I like to downgrade it to 1.2 via software.
Firstly I updated between versions based on 2.0, totally official, not mod inside.
The other user give to me a compressed file with Infineon TPM flasher and lot of versions, all official, both to update and downgrade too. Only some combination possible.
Issue is that I can't officially downgrade from my TPM 2.0 version to 1.2, I told the issue on both posts. This is the reason because I want the mod.

@Fernando

I get the files from another user, he uploaded one copy of Infineon flasher and a lot of official combinations of upgrade and downgrades.
Infineon since 2017 has not more updates because now every brand make the changes, not Infineon.
I uploaded the files into a rar file, the original has the end of the file name on "0", the mod ones has number "2".
