    INVALID entries in BIOS of Lenovo Yoga C630-13Q50 Windows on Snapdragon 2in1

    Hello,

    I have a Lenovo Yoga C630-13Q50 Windows on Snapdragon laptop that I bought used here in Japan. They only sell the 4GB RAM version here in Japan so I decided to purchase an 8GB motherboard off of Aliexpress. The motherboard works without issue but Product ID, MTM, and Lenovo SN entries in the BIOS are INVALID.

    I would like to input the values from the old motherboard. After searching the internet I learned about LVAR and have tried to use it to input the values but I get the following error.

    I have tried placing the LVAR folder on C drive and Desktop with no luck.

    So I found the Lenovo Golden Key download and made a bootable USB. After booting into the Golden Key I found my device listed under other tools, but it says the tools are meant to be used in Windows.

    Going into the gku1tools folder on the USB there is a folder for my device. In the folder is a utility called ControlWosEEPROM.exe.

    Does anyone know how to use this tool to update my MTM, SN, and ID?

    Sharing the latest version of Lenovo Golden Key I found to change DMI information such as serial number, MTM, UUID. Run the U1 application and create a bootable USB. It may show an older version upon making the usb. Restart the program and it will update the USB to the next version available. For some reason the updater program

          I will outline my steps.

          I downloaded the Lenovo Golden Key toolkit from here. After making a USB stick I copied the files from gku1tools->YogaC630_13Q50 folder; WinWOS.bat and the ODMTools folder.

          I copied those to C:\ and opened a PowerShell prompt on C.

          With the following commands I was able to write a MTM, SN, and ID to my BIOS

          Code:
          .\WinWOS.bat /w /ln "SERIALNUMBER"

.\WinWOS.bat /w /mt "MACHINETYPE"

.\WinWOS.bat /w /pn "PRODUCTNAME"
          Putting the actual values in the quotes.

          I got all this information from this post on reddit.
