    Tks for your reply

    I tried your method but eror:
    -----
    D:\>
    D:\>flashrom -r 850g2lock.bin
    flashrom v0.9.9-97-g29333a0 on Windows 6.2 (x86)
    flashrom is free software, get the source code at https://flashrom.org

    Calibrating delay loop... OK.
    Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on ch341a_spi.
    ===
    This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE
    The test status of this chip may have been updated in the latest development
    version of flashrom. If you are running the latest development version,
    please email a report to [email protected] if any of the above operations
    work correctly for you with this flash chip. Please include the flashrom log
    file for all operations you tested (see the man page for details), and mention
    which mainboard or programmer you tested in the subject line.
    Thanks for your help!
    Read is not working on this chip. Aborting.
    -----
    I dont know why?
    May be the flashrom cmd can not run on win 10?
    Thank you!
