    Unfortunately, nothing can be done, probably remains the only repair service, thanks for your help.

    They are not removed. Andy's tool skips them.

    When you open the efi, EzH20 crashes. So you have to cut the firmware volume (_FV) which contains the SLIC. This binary can be opened with EzH20 2.1.0.4 (do not use newer versions since they can open the entire bios, but deny the changes made at the physical memory).

    When opened it gets LZMA decompressed and is located at the physical memory uncompressed. So you can browse the physical memory with winhex to find the pubkey and marker 2.0 to replace.
    When you save the file with EZH2O all the changes that are made are saved and LZMA compressed again.

    So finally I copied and wrote back the FV to its original offset WITHOUT to correct the checksums of the EFI. So when andy's tool parses my mod it skips more than 30 modules when decomposing.

    So you think they are missing, but in fact they are skipped.
    This is a very reliable method and was developed by me (direct edit idea) and Oho77 (cut of FV when EZH20 crashes).

    This was the first method to mod LZMA compressed EFI before andy's tool could mod them.

    I have PM'ed andy about to ask why a mod of his tool doesn't work and my mod does.

    You don't need to correct the other checksums when reinserting the FV, it always works.
    Only 'problem' has andy's tool. It skips modules if sums are wrong and you think that they are missing.

    All modules are still present at my mod..:)

    Open my mod with andy's tool. You don't find any pubkey or marker. Anyway they are there (BIOS is working and activating ;)).
