    Transfer Windows-Key from bad BIOS to new BIOS

    Hi,

    the situation:

    I get a laptop with bad bios (mostly DELL).
    Then I try to find and download a suitably ROM-File for that BIOS.
    Next I solder out the BIOS chip and read it in an external programmer.
    Sometimes in the new BIOS there is a Windows key included - so I overwrite the key with the one from my BIOS-extraction.
    Then I reprogram the chip with the BIOS I found here.
    In most cases windows is working with my original key.

    But the most ROM-Files contain no windows key.
    And later if I check in Windows I get the information "Unable to open MSDM table".

    My question:
    Is it possible to transfer the information from the bad ROM to the working ROM?

      Re: Transfer Windows-Key from bad BIOS to new BIOS

      i asked same on MyDigitalLife (thay made cotribution to win7 activator) but never got replay

      sometimes keys can be extracted from working machine and inserted with phoenixtool (slic2.1, win7 key) but for win10 i never found solution

      if you want to experiment you can send me 2 working bios, with key and without key so we can try to make it

      lots of time and reflashing will be needed
      Im Back... sort of...

          Its always best to try and repair the original bios to preserve any windows keys,and dmi info. Win 7 oem keys and slic table can be edited in with a hex editor or phoenixtool.Win 8 keys,if any,with hex editor. Laptops with win 7,8 that were upgraded to win 10 will have a digital entitlement key,you can find that key with ShowKeyPlus .

              I can pull out the key if the DMI table around it is damaged.
              Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

              You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

              Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

                  Quite old topic, but any progress - maybe different topic? I've got DELL Optiplex 9020 with physical sticker and would like to "transfer" it into BIOS

                          How to transfer information from one BIOS to another?
                          by someonenotyou
                          Hi.
                          I am starting to learn about UEFI BIOS.
                          At the moment I have Lenovo laptop with bad BIOS.
                          I tried to clean ME region and transfer EC region from a known working BIOS, but the laptop does not POST (just fan spin).
                          So there is something else bad.
                          If I flash a know working BIOS, the laptop POSTs and boots into Windows.
                          But the problem is, that the serial numbers, Windows key, and every thing else is from another laptop.


                          Where do I start to transfer the S/N, Windows key and other information from one BIOS to another?

                          Thank y...

                          ASUS TP500LA BIOS request/repair/merge?
                          by jbonavita
                          Hi, my laptop wont boot at all
                          With original bios no POST, only LED lights
                          With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                          Some issues
                          A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                          B- If updated from 500LN version 203 to 300, the battery stops being recognized

                          Things I tried

                          1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                          by zenius
                          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                          by Wahaz
                          Hello,

                          I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                          So I thought it was a Bios problem.
                          I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
