Hello, There I made a worst mistake I upgraded to MOD bios for Acer Aspire V3-571G 1.13v to 2.09v Modded and now I am unable to switch to my Nvidia Graphics 640m please can you help downgrade
I tried to modify Platform.ini and have tried recovery method nothing worked
the recovery method ends with 3 beeps and the bios remains same.

Anyway we can get rid of error" update to 2.x " and or " not supported this version of flash common interface! "

just to add my system is Windows 7 based so it doesn't ve that EFI thing and I really don't want it. Don't know why I did it.
