First off, Acer needs to put a warning that once you upgrade the bios to UEFI, you cannot downgrade (or at least easily). I upgraded from 1.09 to 2.21 and UEFI is **bleep**.  Nothing but troubles. 

 

1.  Try to run Legacy Bios and Installer Windows 7 and the USB transfer speeds are ~1MB/S.  I tried every possible work around.  Nothing solves the poor speeds.

 

2.  Upgraded to Windows 8.1 and the headaches persist.  Program incompatibilities with UEFI... Fantastic.

 

Is there any utility I can use to load 1.09 BIOS and flash the computer back to its prior state.  I am absolutely **bleep** that acer PUTS NO WARNING about Bios Downgrades.....

 

So now I'm at the mercy of anyone here to have a work around. I did find a thread where people said "Not Possible"....But Ive got to imagine there's a way to extract the Bios, and Make a Bootable USB and Flash.

 

Step By Step Guide? Assistance Appreciated.

    how you managed  to update from 1.x BIOS version to 2.x?

    as far as i know this is not possible just running the exe file under windows.

    I'm not an Acer employee.
