Windows 10: Downgrade Acer Laptop BIOS

    Downgrade Acer Laptop BIOS

    Hey Guys!
    A few weeks ago I updated my BIOS of acer Aspire E1-572G to the latest version 2.17.
    Since then my laptop has had many problems and now I would like to downgrade to an older version.
    The problem is that acer uses a utility called "InsydeFlash", this utility has a BIOS version checker and won't let me downgrade due to that it shows an error "BIOS version compare error".
    Now many people found a solution to this by editing the platform.ini file and disabling BIOS version check by placing 0 in place of 1 in its flag like this :
    flag=1 to flag=0
    The problem is that in my case its already set to 0 and even then shows me the same error
    Please tell me any possible way I can downgrade my BIOS :/
    Any help would be appreciated!

    Are you sure that you have the correct flag?

    What I see in platform.ini is (just a few lines):


    The flag should be set to zero to prevent checking.

    On the other hand, the update is more than two years old. I hope that Acer wouldn't leave a defective BIOS update in place for that long.

    Thanks for your response bobkn!

    Actually the lines that I edit other than those that you have mentioned are these:

    flag=1 to flag=0

    But in my case the platform file already has the BIOS version checking flag set to 0 even then it shows me the same error as if editing the file didn't do anything .

    The update is infact 2 years old but it might be possible that something wrong happened while I flashed (I don't really remember anything going wrong though)
