acer switch 10 sw5-11

if you try to downgrade the bios or to reinstall the same version, you will receive the message "The version of ROM file is not newer than that of BIOS"

 

I've tried to follow the following instruction:

Unpack the .exe file with something like WinRar or 7-Zip and then in the platform.ini find "[Bios_Version_Check]" and change "flag=1" to "flag=0" after that save the ini file and run the InsydeFlash.exe as administrator.

 

but in the .exe file there is not the platform.ini file.

 

so I have launched the bios exe program and kept it open on error message, copied the unpacked files that he creates in \users\<youruser>\appdata\temp

 

there I have found the platform.ini file to change, but unluckly all the time that I launch again the Insyde program (H2OFFT-W.exe) it overwrite the platform.ini file and all my modifies go lost.

 

How can I downgrade (or reinstall) my bios in my switch 10 sw5-11 ?!?
thank you

    Excuse me, but after so many time, I try an "UP" of my message, as I have not yet found a solution.

     

    Thank you

    Dear.

    Attached modified file that worked for me. This file is modified field Bios_Version_Check.

    Please, copy this file next to the XXXXXXX

    Hi, I did not get it, how do I exactly downgrade the BIOS? I have serious issues, my touchscreen is not working and getting an error message after every reboot (Update Cypress -> Cap Sensor Update FW fail or don't plug.)

    Your touchscreen issues are likely due to a bad driver, not the BIOS.

    Then how can I find a working driver? I did not change any installation, I just used Windows update.
    Thanks

    Open Device Manager and take a look at the USB devices. You likely have one showing an issue... Try removing that device then reboot and let Windows reinstall it.
