acer switch 10 sw5-11 -- downgrade the bios

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
