My model is V3-771, my origal bios version is 1.10. Today I downloaded a revised bios and flashed it. Then my bios version became 2.16 now. But I want to degrade to 1.x now.

 

Anyone know something about it. Thanks in advance.

 

If someone wants to upgrade to 2.x, I could offer you the revised bios.

    We have posted regarding this before.

     

    We do not support cross-flashing from 1.x to 2.x or vice versa, on those systems which shipped with both Windows 7 and Windows 8.

    Windows 7 systems have a legacy BIOS and use v1.x.

    Windows 8 systems have UEFI and use v2.x.

     

    It is very possible to use Windows 8 on a system with a Legacy BIOS and also possible to use Windows 7 on a system with UEFI.  It is never necessary to cross-flash the BIOS.

     

    I'm not sure where you would have gotten a BIOS that enabled you to cross-flash, as none of the posted BIOS revisions allow that to happen.
