    Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

    Hi, I've tried the auto patch and receive an error on running it. Info below.

    Using UEFIReplace to inject 2 DXE drivers...
    [1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
    [2/2] LenovoTranslateService (GUID 826bcf56-bac4-43f4-8ea1-8cdf0a121abd)

    Looking for volumes to patch...
    [1/1] NVRAM_EfiSystemNvDataFvGuid (checksum 2609h):
    Not found... Skipping.

    I've also added a link to the BIOS dump I created. It's for a T450s.
    If someone could let me know how to resolve the error above and or is able to run the patch and pop it somewhere I'd be very, very appreciative!

    *********
    Cheers,

      I also meant to say that I've been looking for a solution to the VNRAM error, however I can't seem to find anything about it.

          Ohh man, sorry I didn't mean to break the rules on that.
          I have some additional system and testing information as well from the link you provided

          I am using a Lenovo T450s
          Model: 20BW-000KUS
          Board Num: Can't locate
          BIOS chip: W25Q128FV

          I can backup the BIOS, backed up multiple times after re-seating the reader as well and on different USB ports to ensure the CRC is the same on all tests.
          I can run the autopatcher and it completes, however with errors.

          Using UEFIReplace to inject 2 DXE drivers...
          [1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
          [2/2] LenovoTranslateService (GUID 826bcf56-bac4-43f4-8ea1-8cdf0a121abd)

          Looking for volumes to patch...
          [1/1] NVRAM_EfiSystemNvDataFvGuid (checksum 2609h):
          Not found... Skipping.

          If I write this to the chip I get 5 beeps, twice, then a display and press F1 and next a password prompt.
          Pressing Enter will just result in a blank screen.

          I can write the original backup BIOS back to the chip without any problem and it boots back to the previous state.

          I've attached the BIOS to this post, if possible would someone be able to run the autopatch for me please?

          Cheers,
          T.SS.T

              And there it is, all in how you read it. Thanks for pointing out my brain failure. ha!

              Gave it 1234, proceeded to the next steps on the instructions and I am good to go.
              BIOS completely unlocked!

              Thanks again and for all who have contributed to this tool, wicked work.

                  How exactly did you try? Upload the patched file to see what you did.
                  What is this file with a strange size you have attached?
                  Have you tried to merge both 8MB and 4MB bios dumps? Why?

                      Yes, of course. Only 4MB dump must be patched!

                          In that case, you make a mistake somewhere, start all over again.
